Two 650-foot-tall (200-m) towers have risen in China's Gansu Province. Combined with an array of 30,000 mirrors arranged in concentric circles, the new facility is expected to generate over 1.8 billion kilowatt-hours of electricity every year.

While photovoltaic panels that directly convert sunlight to electricity are what most people think of when they hear the term "solar power," there is another method of harvesting the Sun's power that's been steadily developing since the early 1980s. Known as solar thermal or concentrated solar power (CSP), these systems rely on mirrors known as heliostats to bounce sunlight to a central gathering point. There, the concentrated beams heat a transfer fluid that in turn heats a working fluid. This fluid then evaporates, turns a turbine, and generates electricity.

In 2014, what was then the world's largest solar thermal power station opened in the Mojave Desert in the United States. [The] facility consists of three different towers surrounded by heliostat arrays and has a capacity of 392 megawatts. [...] The world's largest CSP, the Noor Complex Solar Power Plant, now operates in the Sahara Desert in Morocco where it churns out 510 megawatts of power.[...]

Much like the facility in the US, the Ghazhou solar thermal energy storage project will use multiple towers: in this case, two of them, both sharing the same steam turbine.

But unlike the US facility, where each tower is surrounded by its own field of heliostats, the Chinese project will deploy a field of mirrors set in overlapping concentric circles. The mirrors will then be able to follow the path of the Sun and reflect light to either tower in the most efficient way possible. It's an advance that will improve CSP efficiency significantly, says project manager, Wen Jianghong.

"The mirrors in the overlapping area can be utilized by either tower," he said. "This configuration is expected to enhance efficiency by 24 percent." Helping that efficiency along is the fact that the mirrors being used have a 94% reflection efficiency, meaning that most of the solar energy that hits them is beamed back to the power-producing towers.

Research abounds at the International Space Station

At the International Space station, researchers are making strides in everything from Earth science to chemical properties. Here's what they're up to and why it matters.

Recently, researchers have found that eddies, or swirling wind patterns, increased moisture evaporation in an alfalfa field. A better understanding of the complex exchange of water and heat between the ground and atmosphere could improve remote sensing products and their use in agricultural water management.

The station's ECOSTRESS instrument takes high-resolution thermal infrared measurements of Earth's surface that provide data on changes in water availability, vegetation water stress, and agricultural water use. Researchers use observations from the USGS Landsat 8 and 9 satellites and ECOSTRESS to validate climate models and update data on Earth's surface energy (the amount of energy absorbed from the sun and radiated back into the atmosphere).

Properties of flow boiling

Researchers have identified various properties for flow boiling using n-perfleurohexane, a fluid used to cool electronics. A better understanding of this process can improve models for designing thermal cooling systems used in the electronics, energy, aerospace, and other industries.

Flow boiling, a method of thermal management, uses the heat generated by a device to boil a liquid, generating vapor bubbles that lift the heat from the surface. The Flow Boiling and Condensation Experiment (FBCE) tested a flow boiling method in microgravity, where the process is less efficient; in the absence of buoyancy, bubbles grow larger and remain near the surface.

A new radiation-resistant polymer

Researchers successfully manufactured a polymer of rare metals and other elements that showed high radiation resistance and has a suitable size and weight for use in space. This result provides knowledge that can support development of improved shielding for future spacecraft and extraterrestrial habitats.

The Roscosmos investigation Shielding Composite tested the absorbed radiation dose of two polymers during 225 days on the space station using monthly monitoring by the Pille-ISS investigation. The data showed that the material has high and stable radiation shielding characteristics. Protecting crew members and equipment from radiation is an important requirement for future long-duration space missions.

Copper is one of the most popular pipe materials used in solar thermal systems, especially for domestic hot water applications.  It has excellent thermal conductivity, making it efficient in transferring heat from the solar collectors to the storage tank.  Copper is also highly resistant to corrosion, which ensures a longer lifespan for the pipes.  Additionally, copper pipes can withstand high temperatures and pressure, making them ideal for solar systems.

However, copper can be expensive compared to other materials.  It is also susceptible to theft, so additional precautions may need to be taken in certain locations.

2.   Stainless Steel

Stainless steel is another common choice for solar system pipes due to its high resistance to corrosion, excellent thermal conductivity, and ability to withstand extreme temperatures and pressures.  Stainless steel is particularly well-suited for larger solar thermal systems used in commercial or industrial settings, as it can handle the demands of heavy-duty applications.

While stainless steel pipes are more expensive than some other materials, they offer exceptional durability and longevity, making them a cost-effective choice over the system’s lifespan.

3.   PEX (Cross-Linked Polyethylene)

PEX pipes are made from a type of plastic that is flexible, durable, and resistant to corrosion.  PEX is often used in solar thermal systems for domestic hot water applications due to its lower cost and ease of installation.  PEX pipes are particularly useful in systems where the fluid temperature is moderate, as they can withstand temperatures up to 200°F (93°C).

However, PEX is not suitable for high-temperature or high-pressure solar systems.  It is best used in smaller residential applications where the conditions are less extreme.

4.   Polypropylene (PP)

Polypropylene pipes are increasingly being used in solar systems due to their excellent resistance to high temperatures, UV radiation, and corrosion.  They are particularly well-suited for large-scale solar thermal systems and solar district heating systems.  PP pipes are lightweight, easy to install, and can handle temperatures up to 248°F (120°C).

One of the main advantages of PP pipes is their environmental friendliness.  They are fully recyclable and have a low carbon footprint, making them an excellent choice for sustainable energy systems.

The Importance of Choosing the Right Distributor

Selecting the right pipe material is only part of the equation.  Working with a reputable pipes for solar system works distributor in Vadodara or pipes for solar system works distributor in Gujarat is equally important to ensure you receive high-quality products that meet your system's specifications.

Elements

All magic in the Next World falls under a certain elemental bias. Elements are odd though, for many reasons. Most notably, despite there only being seven magical elements, they are incredibly broad, and very abstract. There is no “fire” or “plant” or “water”, but rather elements that encompass those uses, as well as unimaginable amounts of others. Additionally, certain elements are very non-standard, and direct the usage of abilities not commonly seen in magic systems.

Toyhou.se information profile here! More up to date and will be updated.

However, even with the broad range in each element, an item or individual with an elemental affinity cannot manipulate any concept in an element’s range. Rather, actual usage of an element must be precise, and will inherently be channeled differently between users or devices. Two users of the same element are unlikely to have remotely similar magic abilities.

As mentioned prior, there are seven elements of magic:

Thermal is the element of temperatures, heat and cold, the properties of temperatures, and concepts heavily linked with temperatures. 

Geologic is the element of rocks, minerals, metals and crystals, as the direct material, their properties, or common uses.

Power is the element of energy, as the usage of energy, creation of energy, and types of energy.

Organic is the element of living things and compounds, in the form of aspects of living things, organic materials, or associated properties. 

Fluid is the element of liquids, properties of liquids, or liquid-like states.

Force is the element of unseen forces, in the form of physical forces and their effects, or conceptual forces and their effects.

Artificial is the element of manmade things, both physical and conceptual.

Every Mirribeast has one elemental association, and a specific usage of this element. As far as the element system goes, their magic usage is completely normal, minus their ability to use it on their own.

When the SR-71 was getting low on gas, its crew members pressure suits started to warm up. So aboard the Blackbird the fuel was used as a heat sink. Here’s how.

SR-71 Blackbird crew members have said that they sometimes came down looking for a tanker, not so much because they were running out of gas but because their gas was getting too hot.

My Dad, Colonel Richard “Butch” Sheffield, SR-71 Blackbird Reconnaissance Systems Officer (RSO), wrote in his unpublished book “The Very First” that when they were getting low on gas in the SR-71, Blackbird crew members pressure suits started to get a little warm up. By contrast bringing on new fuel cooled them down. Aboard the SR-71 the fuel was used as a heat sink.

Everything about the SR-71 was complex yet incredibly engineered, so they have to find a way for the Blackbird to deal with the enormous amount of heat generated by its high-speed flight.

‘Flying at over Mach 3 is a thermal problem. Everything is too hot, including any air you slow down to interact with the vehicle. You are trying to make the vehicle (and the pilots inside) survive for hours in a pizza oven, while they are getting cozy with two 500 million BTU/hour flamethrowers,’ Iain McClatchie, an aviation and turbine engine expert, says on Quora.

When the SR-71 was getting low on gas, its crew members pressure suits started to warm up. So aboard the Blackbird the fuel was used as a heat sink. Here’s how.

‘When you look at a graph like this, your first impression might be that the vehicle is this glowing hot thing slicing through the icy -52 C air at 80,000 feet. So naturally, you think of the air as cooling the airplane down.

‘Not so much. The air has to change to the vehicle’s speed to touch the vehicle, and that requires work. That work heats the air. At Mach 3.2, the stagnation temperature of the air is 740 F, which is hotter than every (labelled) point on the above graph! (The nacelles around the engine afterburners, unlabelled, are in fact hotter than the air around them.)

‘I know, it seems unbelievable. Use this handy graph and see for yourself.

When the SR-71 was getting low on gas, its crew members pressure suits started to warm up. So aboard the Blackbird the fuel was used as a heat sink. Here’s how.

‘Basically, the shocks from the airplane heat the air around it, but the vehicle itself cools the air in contact with it down. Once the airplane passes by, all that disturbed air tumbles to a stop, leaving a path of hot air through the upper atmosphere.

‘So back to life in the pizza oven. The basic solution is (a) leave most of the airframe hot and make it out of stuff like titanium and stainless steel that are strong when hot, and (b) start with a large amount of cold fuel, and then dump heat from critical areas into the fuel before burning it. When decoupling from an aerial tanker, half the SR-71’s weight was fuel.

‘A special type of kerosene fuel, JP-7, was developed for the SR-71 to be good as a heat sink. It boils away at 285 C at 1 atmosphere pressure, which is the upper end of the kerosene range. When the plane tanked up at 30,000 feet, the kerosene might start below 0 C. At speed, it would be used to cool the avionics and cockpit, and by the time it arrived at the engine it would get up to 177 C. It was then used as hydraulic fluid for the various engine actuators, primarily the variable geometry nozzle. By the time it got to the fuel injectors it had gotten up to 316 C (but wasn’t boiling because it was at several atmospheres of pressure). At cruise the burner cans were at 330 kPa (about 3.3x the pressure at sea level), so the fuel still didn’t boil as it left the nozzles but the droplets would have evaporated very quickly.’

When the SR-71 was getting low on gas, its crew members pressure suits started to warm up. So aboard the Blackbird the fuel was used as a heat sink. Here’s how.

McClatchie continues;

‘JP-7 is mostly a mix of hydrocarbons centered around C12H26 (dodecane). The graph above shows the vapor pressure of dodecane as a function of reciprocal absolute temperature. That makes it a bit hard to read. 0.0024, for instance, is 417 Kelvin which is 143 Celsius. Liquids start to boil when their vapor pressure is greater than the ambient pressure. I’ve labelled the boiling point of dodecane at 2900 Pa, which is the absolute pressure at 80,000 feet, and 13000 Pa, which is the minimum absolute pressure in the SR-71 fuel tanks. Note that the dodecane component of JP-7 starts to boil at 162 C at sea level… quite a bit less than the advertised 285 C which is actually when the stuff boils away completely.

‘The flash point of JP-7 is 60 C. The fuel was held in tanks whose walls were formed of the skin of the vehicle. Since fuel vapor against the top skin of the vehicle would be well over 60 C during cruise, if air was allowed in any ignition source in the tank would cause a deflagration and destruction of the vehicle. Instead, nitrogen gas from a 260-liter liquid nitrogen dewar was used to pressurize the tanks. This would have mostly been an issue during descent, when the ambient pressure rose and extra gas was needed to fill the tank ullage space.

‘But nitrogen gas fill was not enough. The fuel was heated in the tank by the bottom surface of the vehicle, just as water in a pot is heated by the flame on a stove. In this case the fluid was over a meter deep in the tank and consequently took longer than a pot does to boil. At ambient cruise pressure the fuel would have begun to simmer in the tanks at 116 C. By pressurizing the tank to 10 kPa over ambient, the tolerable tank temperature rose by 33 C. This temperature limit put a time limit on how long the SR-71 could stay at cruise before it began to lose fuel to boiling.

Blackbird Pilot explains why the SR-71 had to refuel right after takeoff (and it’s not because it leaked fuel)

‘The fuel pumps in the tanks raised the fuel pressure so that boiling was no longer a problem once in the fuel system. The limit of how much heat could be absorbed by the fuel was rather set by it’s coking temperature — the temperature at which the fuel begins to deposit varnish on the interior of whatever plumbing it is in. I don’t have a specific number on JP-7, but it must be higher than 316 C. There was another experimental hydrocarbon blend developed, called JP-900, which resists coking up to 482 C. This was intended for a higher speed vehicle that was never built.

‘They were not able to get the wind tunnel behavior to match the actual behavior of the airplane. Kelly Johnson speculated that this was because during cruise, the fuel sitting against the lower skin of the fuselage and inner wing kept that portion of the airframe cooler than the upper skin. This caused the vehicle to bow from the differential temperature expansion, which would have made the wings slightly anhedral and would have made the vehicle unstable in roll.’

McClatchie concludes;

‘Heating of the fuel while in the tanks caused yet another problem. As I said earlier, the engines can take the fuel at a maximum temperature of 177 C. So as the fuel in the tanks heats up, it’s ability to absorb heat on the way to the engine decreases. Flight crews have said that they sometimes came down looking for a tanker, not so much because they were running out of gas but because their gas was getting too hot.

‘Using fuel as a heat sink is common in fast jets. The Concorde did it, the F-15, F-16, F-18, F-22, and F-35 do it, and probably all other supersonic aircraft.’

Achieve A Net Zero Home Using Geothermal Heating And Solar

In the fight against climate change, net zero homes have emerged as a remarkable solution, pushing the boundaries of energy efficiency and sustainability. But what does it mean, and how does one achieve it? Let’s dive in.

What is a Net Zero Home?

A net zero home is a residential building that generates as much if not more, energy than it consumes. This can be achieved using renewable energy technologies such as solar panels and geothermal heating and cooling systems. 

A Closer Look at How Geothermal Systems Work

We need to start beneath the Earth’s surface to appreciate the science behind geothermal systems. The Earth’s internal heat is transferred to the surface by thermal conduction and convection, resulting in a relatively consistent underground temperature throughout the year, usually between 45°F (7°C) and 75°F (21°C), depending on the latitude. Geothermal systems tap into this reliable and consistent heat source for heating and cooling purposes.

A typical geothermal system consists of three main components: the ground heat exchanger, the heat pump unit, and the air delivery system. The ground heat exchanger is a series of pipes buried near the home, commonly called a loop. Depending on the available space, this loop can be installed vertically or horizontally. These pipes are filled with a heat transfer fluid (commonly a mixture of water and antifreeze).

Heating Mode

In heating mode, the fluid circulates through this loop, absorbing heat from the Earth and carrying it to the heat pump unit. The heat pump then extracts this heat and distributes it throughout the home using the air delivery system, often a system of ducts.

Cooling Mode

For cooling, the process is reversed. The heat pump absorbs heat from the home’s interior, transfers it to the fluid in the loop, which then disperses the heat into the ground. Hence, the Earth serves as a heat sink in summer.

Efficiency Unleashed

Geothermal systems are incredibly efficient because they move heat rather than generate it. According to the U.S. Department of Energy, geothermal heat pumps can achieve efficiencies of 300%-600% on the coldest winter nights, compared to 175%-250% for air-source heat pumps on cool days.

Another advantage of geothermal systems is their lifespan. The indoor components can last about 25 years, while the underground loop system lasts more than 50 years. This long lifespan, coupled with energy savings, makes geothermal systems a desirable option for homeowners aiming for a net zero home.

Though the initial costs of geothermal systems can be higher than traditional heating and cooling systems, the energy savings over time can make them a worthwhile investment. Federal, state, and local incentives can also help offset these initial costs, making geothermal systems more accessible to homeowners.

Harnessing Solar Energy for Home Use to Achieve Net Zero

Solar energy harnessing, especially for home use, has seen significant advancement. It’s a critical component in achieving a net-zero home, and understanding its functionality is vital to maximizing its benefits.

Solar energy harnessing starts with solar panels, often mounted on rooftops, for maximum sunlight exposure. Each panel comprises photovoltaic (PV) cells – semiconductors usually made from silicon. When sunlight hits these cells, the photons from the light stimulate the electrons in the silicon, initiating an electric current. This is known as the photovoltaic effect.

The electricity generated by the panels is typically in direct current (DC). However, most household appliances use alternating current (AC). Therefore, the DC electricity is converted into AC electricity via a device known as an inverter.

Solar panels are most productive when the sun is at its peak – usually in the middle of the day. However, energy demand can extend into the night when the panels aren’t producing electricity. This is where energy storage systems, such as solar batteries, become essential. These batteries store excess energy produced during the day for use during the night or during periods of high demand, ensuring a continuous power supply.

One of the attractive features of solar energy systems is the possibility of grid interconnection. In many regions, homeowners can sell excess electricity back to the grid, a practice known as net metering. It reduces energy costs and can lead to energy credits when more power is generated than used.

Combining Solar and Geothermal Power for Net Zero Homes

Combining solar and geothermal power systems can be a powerful approach to achieving net zero energy status in homes. Both technologies complement each other, providing a more balanced and stable energy supply throughout the year.

Take, for example, a scenario where a home is equipped with both a solar panel system and a geothermal heat pump. During the summer months, the solar panels can generate electricity during the day to power the home, with excess power stored in batteries for use at night. The geothermal system, on the other hand, can provide efficient cooling, taking advantage of the stable underground temperatures to dissipate heat from the home. Any excess power generated by the solar panels could also be used to power the geothermal system or be fed back into the grid, resulting in energy credits. 

In winter, while the efficiency of solar panels might reduce due to fewer sunlight hours (shorter days), the geothermal system can take over, providing highly efficient heating. The heat pump draws heat from the ground and distributes it throughout the home. Solar panels can still contribute to the home’s energy needs during the day, reducing the load on the geothermal system and resulting in more efficient energy use.

Major Geothermal Projects in Alberta – Eavor-Loop

A groundbreaking geothermal project, valued at $10 million and currently being built in the heart of Alberta, is being celebrated as a significant innovation due to its independence from fracking or water and its zero greenhouse gas emissions.

Upon his visit to the construction site close to Rocky Mountain House, Alberta’s Infrastructure Minister Prasad Panda lauded the pilot project as a major turning point.

The project, known as the Eavor-Loop, is unique in its kind, according to John Redfern, the president and CEO of Eavor Technologies, which is headquartered in Calgary.

Geothermal energy, which is a sustainable form of energy drawn from the Earth’s stored heat, operates much like a radiator in this closed-loop geothermal project, explained Redfern.

He added, “We’re utilizing conventional components, but assembling them in an unconventional manner.”

He further explained, “For instance, our approach contrasts with standard practices. Generally, when drilling a well, the objective is to prevent intersecting another well. However, we aim for intersection in our operation… We commence a few kilometers apart, drill down a similar distance, then take a right turn and drill towards each other, connecting one well with the other, thus forming a massive U-shaped well.

“This technique essentially generates a radiator effect.”

The Eavor-Loop recently gained financial support of $1 million from Alberta Innovates and Emissions Reduction Alberta.

Rebates and Incentives

While the initial costs of installing solar and geothermal systems can be significant, the energy savings over time make them cost-effective. Additionally, homeowners can benefit from government incentives, rebates, and tax credits designed to encourage the adoption of renewable energy technologies. As part of the Canada Greener Homes Initiative, homeowners have access to federal grants and provincial grants and interest free loans up to $45K. New residential homes can save 25% of your CMHC premium through the CMHC Eco Plus program.

Completed experiments on International Space Station to help answer how boiling and condensation work in space

After a decade of preparation and two years of active experiments in space, a facility that Purdue University and NASA's Glenn Research Center in Cleveland designed, built and tested has completed its test campaign on the International Space Station.

The Flow Boiling and Condensation Experiment (FBCE), led by Purdue professor Issam Mudawar, gathered vital data for engineering innovations to help astronauts travel farther into space and conduct long-duration missions on the moon or Mars. The data will also support the design of future spacecraft propulsion, thermal management systems, in-space refueling and vapor compression heat pumps for planetary bases.

"We were asked to create an experiment to test flow boiling in microgravity, and I'm thrilled to see that we've delivered in a big way," said Mudawar, the Betty Ruth and Milton B. Hollander Family Professor of Mechanical Engineering and FBCE's principal investigator. "The amount of data coming out of the FBCE is just absolutely enormous, and that's exactly what we want."

Mudawar's space-based experiment tackles a simple question: How do we keep future vehicles and facilities cool in space's harsh environment? For example, the moon's surface fluctuates wildly between minus 410 degrees and 250 degrees Fahrenheit; to create a human habitat there, reliable thermal management will be essential.

Traveling farther into space requires cryogenic fuel depots, but the flow physics of cryogenic liquids in microgravity haven't been fully understood. Even future propulsion systems, such as nuclear fission or Rankine cycle heat engines, will also require efficient cooling systems capable of operating in a zero-gravity environment.

For all these reasons, NASA solicited research proposals on the topic and selected a proposal submitted by Mudawar, who is one of the most cited researchers on flow boiling and condensation, and Glenn's Mojib Hasan.

In flow boiling, heat is removed by flowing a liquid that then boils, phase-changing into a gas, and then later condensing back into a liquid. While this efficient thermal management solution has been studied in-depth on Earth, no one knew if it was feasible in space.

"We have developed over a hundred years' worth of understanding of how heating and cooling systems work in Earth's gravity," Mudawar said, "but we haven't known how they work in weightlessness."

Enter the FBCE, which started operating on the space station in 2022. About the size of a refrigerator, FBCE contains two Purdue-designed test modules—one for flow boiling and one for condensation—integrated with a fluid system that Purdue researchers and NASA Glenn designed together. NASA Glenn built the fluid system along with avionics modules. Sitting in the space station's Fluids Integrated Rack, the fluid system enables researchers to conduct space station experiments autonomously from the ground.

"The FBCE experiments are crucial in two ways," Mudawar said. "Not only do they generate fundamental data that would be difficult for us to gather on Earth, but they also serve to validate theoretical models that we have spent years developing. Once the models are validated, it becomes possible for NASA to more accurately predict the fluid physics of lower-gravity environments, such as the moon or Mars."

Boiler up

Mudawar started this project in 2011 when NASA selected his proposal after a decadal survey from the National Academies emphasized the need for this research.

"Every 10 years, the National Academies conduct a survey that advises NASA what specific aspects they should focus on," Mudawar said. "This report indicated a lack of fundamental models of how fluids behave in microgravity. That's when I began work with NASA Glenn to create an experimental facility to study fluid flow and phase change in space."

The first prototype FBCE flew on parabolic airplane flights with Zero Gravity Corp. (ZERO-G). Purdue students and NASA Glenn-qualified operators conducted experiments on that flight during 15-second periods of microgravity. After promising results and years of hardware development, testing and flight qualification, the final version of the facility came together at NASA Glenn.

After passing NASA's design, safety and readiness reviews, FBCE's flow boiling module was launched to the space station in August 2021 and began operations in early 2022. Last August, the condensation module of FBCE launched, replacing the flow boiling module. Purdue completed its test campaign in July.

The mountains of data gathered from FBCE's experiments will form the basis of fundamental models and future research for years to come.

"This is among NASA's largest and most complex experiments for fluid physics research," Mudawar said. "We have published more than 70 papers on reduced gravity and fluid flow since the project's inception and even contributed to the most recent National Academies decadal survey based on our findings. Collectively, these papers are really almost like a textbook for how boiling and condensation works in space."

Cool future

While the Purdue test campaign has ended, FBCE isn't going anywhere. The facility will remain on the space station for other researchers who want to experiment with fluid physics in space.

"My original proposal established that FBCE would eventually become a national resource," Mudawar said. "Other investigators have already started using it since our campaign ended. It's my hope that the data coming from FBCE will help establish the science of cooling spacecraft for years to come."
