#9v lithium ion battery

[useless-polls]

[n-and-uzi-chat-abt-things]

I noticed some drones eat batteries. Do the various compositions (Zinc, Alkaline, Nickel Cadmium, Nickel Metal Hydride, Lithium Ion, Lithium Polymer) taste different, same across the sizes like AA, AAA, C, D, 9Vs. Am genuinely curious.

Uzi: Batteries are Batteries ig lol

[riflebrass]

Dude lithium 9Vs are insane. I tried getting Energizer/Duracell for my rangefinder but nobody local carries them in lith. All I could find was a weird brand called Dura-Ready or some shit and that was dead right out of the pack.

Looking them up on Amazon I didn't see any lithium duracells so I don't know if they actually make them. Energizers are like $16 a piece which is just insane for a 9V.

The best deal I could find were some rechargeable lithium ions. Comes with a 4 pack and a charger for like $28. Wild to think that's even cheaper than just two non-rechargable Energizers.

I might go with this one. I need a new battery for the range finder, another one for the tuner built into my guitar, and a battery on backup for the shot timer would be a good idea.

How Mobile Phone Charging Technology Works

Mobile phone charging technology has become an essential part of our daily lives. Understanding how this technology works can help users make better choices regarding their devices and charging habits. This article delves into the mechanics of mobile phone charging, covering traditional wired charging, fast charging, and wireless charging.

Traditional Wired Charging

Traditional wired charging is the most common and oldest method of charging mobile phones. It involves connecting a charger to the phone via a USB cable. The process begins when the charger is plugged into an electrical outlet. Here's a step-by-step look at how it works:

Power Source: The charger is connected to a power source, typically a wall outlet. The charger converts alternating current (AC) from the outlet into direct current (DC), which is suitable for battery charging.

Power Transfer: The DC power is transferred through the USB cable to the mobile phone. Inside the phone, the charging port receives this power and directs it to the battery.

Battery Charging: The battery management system (BMS) in the phone regulates the amount of power sent to the battery to prevent overcharging and overheating. Lithium-ion batteries, commonly used in phones, charge through a two-phase process: constant current (CC) and constant voltage (CV). During the CC phase, the battery receives a steady current until it reaches a set voltage. Then, during the CV phase, the current decreases as the voltage remains constant until the battery is fully charged.

Fast Charging

Fast charging technology has gained popularity due to the increasing demand for shorter charging times. It works by delivering higher power levels to the phone's battery. Here’s how it differs from traditional charging:

Increased Power Output: Fast chargers supply more power (measured in watts) compared to standard chargers. This is achieved by increasing the voltage and/or current. For instance, a traditional charger might provide 5 watts (5V/1A), while a fast charger can deliver 18 watts or more (9V/2A or 12V/1.5A).

Optimized Battery Management: Phones equipped with fast charging technology have advanced BMS that can handle higher power inputs safely. These systems monitor the battery's temperature and charge level to adjust the power flow, ensuring efficient and safe charging.

Enhanced Charging Protocols: Various fast charging standards exist, such as Qualcomm Quick Charge, USB Power Delivery (PD), and proprietary technologies like Apple's Fast Charge or Samsung's Adaptive Fast Charging. These protocols determine the power levels and communication between the charger and phone to optimize charging speed and safety.

Wireless Charging

Wireless charging offers a convenient way to power up mobile phones without the need for cables. It uses electromagnetic fields to transfer energy between two coils: one in the charging pad and the other in the phone. Here’s how it works:

Inductive Charging: The most common type of wireless charging, inductive charging, relies on electromagnetic induction. When the phone is placed on the charging pad, an alternating current passes through the pad's coil, generating a magnetic field. This magnetic field induces a current in the phone's coil, converting it back into DC power to charge the battery.

Resonant Charging: A less common but emerging technology is resonant charging. It allows for more flexibility in positioning the phone on the charging pad. It operates on similar principles but uses resonant inductive coupling, which enables energy transfer over greater distances compared to inductive charging.

Efficiency and Convenience: While wireless charging offers convenience, it is generally less efficient than wired charging due to energy loss in the form of heat. However, advancements in technology are continuously improving the efficiency and speed of wireless charging.

Conclusion

Understanding how mobile phone charging technology works can help users make informed decisions about their devices and charging practices. Traditional wired charging, fast charging, and wireless charging each have their mechanisms and benefits. As technology advances, we can expect even more efficient and faster charging solutions to become available, further enhancing the user experience.

Power Supply for Espressif Module with Battery Charger & Boost Converter

We will discuss the integration of a power supply for the ESP32 Board. Additionally, we will add a Boost Converter Circuit to enable the use of a 3.7V Lithium-Ion Battery for powering the ESP32. Since Lithium-Ion Batteries can discharge, we will integrate a Battery Charger Circuit along with a Battery Management System. Many Lithium-Ion/Lithium Polymer Batteries can only charge up to 4.2V, which is low for the ESP32 Board.

Therefore, we need to increase the battery voltage from 2.8V-3.7V to 5V. This necessitates the use of a compact Boost Converter Module build with inductors, ICs, and resistors. To facilitate battery charging and management, we will use the TP4056 Battery Charger Module. Alternatively, we can also power the circuit using a 9V/12V DC Adapter. The LM7805 Voltage Regulator IC restricts the voltage to 5V. If you are not going to use a battery for power, you can utilize the DC Power Adapter or a 9V Battery.

ESP32 Power Requirement

The ESP32 Board’s operating voltage is between 2.2V to 3.6V. But we can supply 5V from the Micro-USB port. For applying 3.3V there is already an LDO voltage regulator on the module to keep the voltage steady at 3.3V. ESP32 can be powered using Micro USB port and VIN pin (from external supply).

The power requirement of ESP32 is 600mA of that ESP32 pulls only 250mA during the RF transmissions. When it is performing boot or wifi operation it’s drawing more than 200mA current. Thus supplying power from Micro-USB Cable is not enough for ESP32 Board when we need to add multiple sensors or modules to the Board. This is because Computer USB port can provide less than 500mA of current. Check more on power requirements of ESP32 here ESP32 Datasheet.

Hardware Requirements

Following are the components required for making this ESP32 Power Supply project. You can get all the components from our Campus Component store.

ESP32 Board-ESP32 ESP-32S Development Board (ESP-WROOM-32)

Battery Charger Module-TP4056 5V,1A Battery Charging Module

3. Input 2-3V, output 5V 150-380mA

4. Input more than 3V, output 5V 380-480mA.

TP4056 Battery Charger Module

The TP4056 module is designed specifically for charging rechargeable lithium batteries through the constant-current/constant-voltage (CC/CV) charging technique. Apart from ensuring the safe charging of lithium batteries, the TP4056 BMS Board incorporates essential protection mechanisms for lithium batteries. It is compatible with both USB power and adapter power supplies. Also because of its internal PMOSFET architecture and anti-reverse charging path, there is no need for external isolation diodes.

TP4056 Module Datasheet.

Power Supply for ESP32 with Battery Charger & Boost Converter

The circuit can be powered by using two methods, one with 9V/12V DC Adapter and other with 3.7V Lithium-Ion Battery.

To power the board through the DC Jack, we've added here a DCJ0202 Female Jack. Also we have added 470uF and 100uF Electrolytic Capacitors that serve to lower the DC fluctuations and eliminate voltage spikes. The LM7805 Voltage Regulator IC is capable of handling input voltages ranging from 7V to 35V, although it's advisable to stay within the 15V limit. Higher input voltages result in increase in heat dissipation thus we have to add a larger heat sink. Connecting the Voltage regulator's output to the Vin pin of the ESP32 and grounding it ensures the module can be powered using a 9V/12V DC Adapter or a 9V Battery.

Alternatively, if opting not to utilize a DC Adapter for ESP32 power, a 3.7V Lithium-Ion or Lithium Polymer Battery can be used. Utilizing the Boost Converter Module, the 3.7V is increased to 5V, operating within the 2.8V to 4.2V input range. The boosted 5V is connected to a switch, and the switch is linked to the 5V Vin pin of the ESP32. The Battery terminal is also connected to the output terminal of the TP4056 Battery Charger Module, allowing the battery to be charged using a 5V MicroUSB Data Cable.

Conclusion

Thus by including a Battery Charger and Boost Converter to power up the esp32, we can create a flexible and efficient power for the unique requirements of the ESP32 platform. Reach out to the Campus Component- an electronics parts suppliers today, if you are building a Battery charger, Boost converter and looking for electronic components such as ESP32 and other microcontrollers from trusted brands such as Mornsun, Espressif, AIT, IKSEMI other components.

How Long Do Smoke Alarm Batteries Last?

When you’re choosing a smoke alarm for your home, you’ll want to find one that lasts for years. There are many types of alarms on the market, ranging from those that are powered by lithium batteries to those that are mains-powered. You’ll also want to ensure that the alarm you choose will be able to detect different types of fires.

Lithium battery

Lithium-powered smoke alarms can last for 10 years. That seems like a pretty good deal if you’re not going to have to replace the battery each year. However, the batteries have to be replaced as a unit.

There are two different types of lithium batteries. One is an alkaline battery and the other is a lithium ion battery. The battery life will depend on the frequency of testing and activation.

Alkaline batteries last longer and have a gradual drop in voltage. Unlike lithium batteries, however, alkaline batteries are less tamper-resistant.

This means that if you tamper with the batteries in a smoke alarm, it can cause fire damage. In addition, some people claim that the chirps that alkaline batteries produce are less accurate than those of lithium-powered alarms.

9-volt battery

If you’re looking for a long-lasting 9-volt smoke alarm battery, then you’ve come to the right place. There are several types of 9V batteries that you can choose from, but not all of them are created equal. You need to make sure you purchase a brand you trust.

First, you should look for a 9V battery that has been marked with an expiration date. This is an important indicator of how long the battery should last.

Another important factor to consider is the manufacturer of your alarm. Many manufacturers recommend that you replace your battery at least once every six months. However, some manufacturers claim that their smoke detectors can last for ten years.

The best way to ensure your smoke detector will last for as long as possible is to buy a quality brand. Those brands are usually more expensive, but they offer better performance. It’s also important to follow the manufacturer’s instructions when using your alarm. Failure to do so can cause your alarm to malfunction.

Mains-powered alarms

Mains-powered smoke alarms are easy to install. They are cheaper to buy, and they have a backup battery that will continue to sound the alarm in case of a power failure. However, their batteries will need to be replaced at least once a year.

The best way to ensure the life of your mains-powered smoke alarm is to replace the battery every year. If your alarm is plugged into a wall socket, you will need to remove the alarm from the base, and then disconnect the wall plug.

Some alarms have a plastic tab that will need to be folded in. You should also check that the battery terminals are free of corrosion. Failing to follow these steps will invalidate the warranty.

Mains-powered smoke alarms use ionization to detect smoke. They are also designed to be hardwired into your home’s electrical system. This means you will need to have a qualified electrician install them.

Chirping

If you have a smoke detector that chirps or makes a noise, you may want to replace the batteries. This is to ensure that your alarm continues to work properly.

You can find smoke detectors with a battery backup, so you will have a constant power source to protect you during a power outage. However, you may find that you need to replace the batteries on your alarm more often than you would like.

There are different types of batteries for different types of smoke detectors, so you need to check for the correct ones. Batteries are also affected by the temperature in your home. They lose power more quickly in colder temperatures.

The best way to make sure you are using the right battery is to test your alarm. Hold the test button for 15 seconds to see if the device produces a louder sound.

Checking the age of a smoke alarm

If you have a smoke alarm, you should check its battery often. You should also have a way to contact your local fire department if you are concerned about the alarm’s health.

Most manufacturers recommend replacing smoke alarms after 10 years. However, some models may last up to five years.

The National Fire Protection Association (NFPA) conducted a survey that found that a majority of Americans don’t know the proper age of their smoke detectors. This is unfortunate because it means that three out of five home fire deaths result from fires in properties without working smoke detectors.

In order to avoid these deaths, you should replace your smoke alarms at least once a year. When you replace the batteries, you should also clean the covers and remove any dust.

Impact Driver vs. Drill: Get the Right Tool for Your Next Job

You must be wondering which one you should buy an Impact driller or a Drill. Before making a decision let us understand the difference between the two. A drill is a home toolbox indispensable for almost any DIY project or to repair home. However, depending on what kind of project is, Impact Driver is used.

At a glance, both of the tools might look similar as they sit on a store shelf, but they have certain differences as well as similarities. Both Brushless Impact Driver and Impact Drill come in cordless and corded models. Offering a reverse direction setting to make releasing fasteners easier. It is true that you can handle all kinds of job by just choosing the right tool.

Most of the time, we are confused regarding the selection of the right tool for a particular job. With so many options available in the market it becomes a little difficult task to understand which tool will be appropriate to finish a task. This becomes more difficult when they perform a similar function. It might not be a difficult task for an expert to figure out but for a person, they are in dilemma.

Well coming to the discussion of 18v Impact Driver vs Drill it can be said that these tools are not interchangeable. This article will guide you to understand the difference between impact drivers and drill so that you make the right choice and sound investment depending on the task that you are willing to accomplish.

Let us point out the difference between the impact driver and a drill-

·         Drill design:

A standard drill-driver is an excellent all-purpose tool. The head has a chuck-keyed or keyless-used to hold bits in place. The tool usually has a low speed used for driving screws and other fasteners and a higher speed for drilling. By contrast, an Impact Driver is more compact and lighter weighted than a standard drill driver and has more twisting force. Usually, Power tool batteries like cordless impact drivers are 12volt, 18volt or 20V.  18V Impact Drivers are used to doing those tasks which cannot be performed with the help of a standard drill.

·         Usage:

Standard drills are basically used for drilling holes and driving in small fasteners. The main purpose of the impact drivers is to drive large fasteners. Large bolts can be driven with more ease if it is performed with long screws, with the use of an adapter. Some basic drilling tasks can e-accomplished with an Cordless impact wrench and Impact Driver set.

The "Going Green" Conundrum.

Here’s another technical perspective on electric vehicles that I thought you might find informative. What is a battery? I think Tesla said it best when they called it an Energy Storage System. That's important. Batteries do not make electricity – they store electricity produced elsewhere, primarily in power plants fueled by coal, uranium or natural gas. So, to say an EV is a zero-emission vehicle is not at all valid.

Also, since forty percent of the electricity generated in the U.S. is from coal-fired plants, it follows that forty percent of the EVs on the road are coal-powered. It takes the same amount of energy to move a five-thousand-pound gasoline-driven automobile a mile as it does an electric one. The only question again is what produces the power? To reiterate, it does not come from the battery; the battery is only the storage device, like a gas tank in a car.

There are two types of batteries, rechargeable, and single-use. The most common single-use batteries are AA, AAA, C, D. 9V, and lantern types. These dry-cell types use zinc, manganese, lithium, silver oxide, or zinc and carbon to store electricity chemically. All contain toxic, heavy metals. Rechargeable batteries only differ in their internal materials, usually lithium-ion, nickel-metal oxide, and nickel-cadmium.

The United States uses three billion of these two battery types a year, and most are not recycled; they end up in landfills. California is the only state which requires all batteries be recycled. If you throw your small, used batteries in the trash, here is what happens to them. All batteries are self-discharging. That means even when not in use, they leak tiny amounts of energy. You have likely ruined a flashlight or two from an old, ruptured battery. When a battery runs down and can no longer power a toy or light, you think of it as dead; well, it is not. It continues to leak small amounts of electricity. As the chemicals inside it run out, pressure builds inside the battery's metal casing, and eventually, it cracks. The metals left inside then ooze out. The ooze in your ruined flashlight is toxic, and so is the ooze that will inevitably leak from every battery in a landfill. All batteries eventually rupture; it just takes rechargeable batteries longer to end up in the landfill.

In addition to dry cell batteries, there are also wet cell ones used in automobiles, boats, and motorcycles. The good thing about those is ninety percent of them are recycled. Unfortunately, we do not yet know how to recycle single-use ones properly. But that is not half of it. For those of you excited about electric cars and a green revolution, I want you to take a closer look at batteries and also windmills and solar panels. These three technologies share what we call "environmentally destructive embedded costs."

Everything manufactured has two costs associated with it, embedded costs and operating costs. I will explain embedded costs using a can of baked beans as my subject. In this scenario, baked beans are on sale, so you jump in your car and head for the grocery store. Sure enough, there they are on the shelf for $1.75 a can. As you head to the checkout, you begin to think about the embedded costs in the can of beans. The first cost is the diesel fuel the farmer used to plow the field, till the ground, harvest the beans, and transport them to the food processor. Not only is his diesel fuel an embedded cost, so are the costs to build the tractors, farm machines, and trucks. In addition, the farmer might use a nitrogen fertilizer made from natural gas. Next is the energy costs of cooking the beans, powering the canning facility, and transporting the workers and materials to the plant. The steel can containing the beans is also an embedded cost. Making the steel can requires mining taconite, shipping it by boat, extracting the iron, placing it in a coal-fired blast furnace, and adding carbon. Then it's back on another truck to take the beans to the grocery store. Finally, add in the cost of the gasoline for your car.

A typical EV battery weighs one thousand pounds, about the size of a travel trunk. It contains twenty-five pounds of lithium, sixty pounds of nickel, 44 pounds of manganese, 30 pounds cobalt, 200 pounds of copper, and 400 pounds of aluminum, steel, and plastic. Inside are over 6,000 individual lithium-ion cells. It should concern you that all those toxic components come from mining. For instance, to manufacture each EV auto battery, you must process 25,000 pounds of brine for the lithium, 30,000 pounds of ore for the cobalt, 5,000 pounds of ore for the nickel, and 25,000 pounds of ore for copper. All told, you dig up 500,000 pounds of the earth's crust for just - one - battery. Sixty-eight percent of the world's cobalt, a significant part of a battery, comes from the Congo. Their mines have no pollution controls, and they employ children who die from handling this toxic material. Should we factor in these diseased kids as part of the cost of driving an electric car?

I'd like to leave you with these thoughts. California is building the largest battery in the world near San Francisco, and they intend to power it from solar panels and windmills. They claim this is the ultimate in being 'green', but it is not! This construction project is creating an environmental disaster. Let me tell you why. The main problem with solar arrays is the chemicals needed to process silicate into the silicon used in the panels. To make pure enough silicon requires processing it with hydrochloric acid, sulfuric acid, nitric acid, hydrogen fluoride, trichloroethane, and acetone. In addition, they also need gallium, arsenide, copper-indium-gallium-diselenide, and cadmium-telluride, which also are highly toxic. Silicon dust is a hazard to the workers, and the panels cannot be recycled.

Windmills are the ultimate in embedded costs and environmental destruction. Each weighs 1688 tons (the equivalent of 23 houses) and contains 1300 tons of concrete, 295 tons of steel, 48 tons of iron, 24 tons of fiberglass, and the hard to extract rare earths neodymium, praseodymium, and dysprosium. Each blade weighs 81,000 pounds and will last 15 to 20 years, at which time it must be replaced. We cannot recycle used blades, so those that are no longer serviceable go to landfills. Sadly, both solar arrays and windmills kill birds, bats, sea life, and migratory insects.

There may be a place for these technologies, but you must look beyond the myth of zero emissions. I predict EVs and windmills will be abandoned once the embedded environmental costs of making and replacing them become apparent. "Going Green" may sound like the Utopian ideal and are easily espoused, catchy buzz words, but when you look at the hidden and embedded costs realistically with an open mind, you can see that Going Green is more destructive to the Earth's environment than meets the eye, for sure.

If this had been titled… "The Embedded Costs of Going Green," would you have read it?

What is a battery?

I think Nicholas Tesla said it best when he called it an Energy Storage System. 

That's an important distinction.

They do not make electricity – they store electricity produced elsewhere, primarily by coal, uranium, natural gas-powered plants, or diesel-fueled generators.  

So, to say an EV is a zero-emission vehicle is not at all valid.

Also, since forty percent of the electricity generated in the U.S. is from coal-fired plants, it follows that forty percent of the EVs on the road are coal-powered, do you see?

Einstein's formula, E=MC2, tells us it takes the same amount of energy to move a five-thousand-pound gasoline-driven automobile a mile as it does an electric one. 

The only question again is what produces the power? 

To reiterate, it does not come from the battery; the battery is only the storage device, like a gas tank in a car.

There are two orders of batteries, rechargeable, and single-use. 

The most common single-use batteries are A, AA, AAA, C, D. 9V, and lantern types. 

Those dry-cell species use zinc, zinc-and-carbon, manganese, lithium, or silver oxide to store electricity chemically. 

Please note they all contain toxic, heavy metals.

Rechargeable batteries only differ in their internal materials, usually lithium-ion, nickel-metal oxide, and nickel-cadmium. 

The United States uses three billion of these two battery types a year, and most are not recycled; they end up in landfills. 

California is the only state which requires all batteries be recycled. 

If you throw your small, used batteries in the trash, here is what happens to them.

All batteries are self-discharging.  That means even when not in use, they leak tiny amounts of energy. You have likely ruined a flashlight or two from an old, ruptured battery. 

When a battery runs down and can no longer power a toy or light, you think of it as dead; well, it is not. It continues to leak small amounts of electricity. 

As the chemicals inside it run out, pressure builds inside the battery's metal casing, and eventually, it cracks. 

The metals left inside then ooze out. 

The ooze in your ruined flashlight is toxic, and so is the ooze that will inevitably leak from every battery in a landfill.

All batteries eventually rupture; it just takes rechargeable batteries longer to end up in the landfill.

In addition to dry cell batteries, there are also wet cell ones used in automobiles, boats, and motorcycles. 

The good thing about those is, ninety percent of them are recycled.

 Unfortunately, we do not yet know how to recycle single-use ones properly.

But that is not half of it.  

For those of you excited about electric cars and a green revolution, I want you to take a closer look at batteries and also windmills and solar panels. 

These three technologies share what we call environmentally destructive embedded costs.

Everything manufactured has two costs associated with it, embedded costs and operating costs. 

I will explain embedded costs using a can of baked beans as my subject.

In this scenario, baked beans are on sale, so you jump in your car and head for the grocery store. 

Sure enough, there they are on the shelf for $1.75 a can. 

As you head to the checkout, you begin to think about the embedded costs in the can of beans.

The first cost is the diesel fuel the farmer used to plow the field, till the ground, harvest the beans, and transport them to the food processor. 

Not only is his diesel fuel an embedded cost, so are the costs to build the tractors, combines, and trucks. 

In addition, the farmer might use a nitrogen fertilizer made from natural gas.

Next is the energy costs of cooking the beans, heating the building, transporting the workers, and paying for the vast amounts of electricity used to run the plant. 

The steel can holding the beans is also an embedded cost. 

Making the steel can requires mining taconite, shipping it by boat, extracting the iron, placing it in a coal-fired blast furnace, and adding carbon. 

Then it's back on another truck to take the beans to the grocery store. 

Finally, add in the cost of the gasoline for your car.

A typical EV battery weighs one thousand pounds, about the size of a travel trunk.  

It contains twenty-five pounds of lithium, sixty pounds of nickel, 44 pounds of manganese, 30 pounds cobalt, 200 pounds of copper, and 400 pounds of aluminum, steel, and plastic. 

Inside are over 6,000 individual lithium-ion cells.

It should concern you that all those toxic components come from mining. 

For instance, to manufacture each EV auto battery, you must process 25,000 pounds of brine for the lithium, 30,000 pounds of ore for the cobalt, 5,000 pounds of ore for the nickel, and 25,000 pounds of ore for copper. 

All told, you dig up 500,000 pounds of the earth's crust for just one  battery."

Sixty-eight percent of the world's cobalt, a significant part of a battery, comes from the Congo. 

Their mines have no pollution controls, and they employ children who die from handling this toxic material. 

Should we factor in these diseased kids as part of the cost of driving an electric car?"

I'd like to leave you with these thoughts. 

California is building the largest battery in the world near San Francisco, and they intend to power it from solar panels and windmills. 

They claim this is the ultimate in being 'green,' but it is not! This construction project is creating an environmental disaster. 

Let me tell you why.

The main problem with solar arrays is the chemicals needed to process silicate into the silicon used in the panels. 

To make pure enough silicon requires processing it with hydrochloric acid, sulfuric acid, nitric acid, hydrogen fluoride, trichloroethane, and acetone. 

In addition, they also need gallium, arsenide, copper-indium-gallium- diselenide, and cadmium-telluride, which also are highly toxic. 

Silicone dust is a hazard to the workers, and the panels cannot be recycled.

Windmills are the ultimate in embedded costs and environmental destruction. 

Each weighs 1,688 tons (the equivalent of 23 houses) and contains 1,300 tons of concrete, 295 tons of steel, 48 tons of iron, 24 tons of fiberglass, and the hard to extract rare earths neodymium, praseodymium, and dysprosium. 

Each blade weighs 81,000 pounds and will last 15 to 20 years, at which time it must be replaced. 

We cannot recycle used blades. 

Sadly, both solar arrays and windmills kill birds, bats, sea life, and migratory insects.

There may be a place for these technologies, but you must look beyond the myth of zero emissions. 

I predict EVs and windmills will be abandoned once the embedded environmental costs of making and replacing them become apparent.  

"Going Green" may sound like the Utopian ideal and is an easily espoused, catchy buzz-phrase, but when you look at the hidden and embedded costs realistically with an open mind, you can see that Going Green is more destructive to the Earth's environment than meets the eye...
