"A net-zero power system is closer than we think.

New research, published by RMI, indicates that an exponential surge in renewable energy deployment is outpacing the International Energy Agency’s most ambitious net-zero predictions for 2030. 

That’s right: Surging solar, wind, and battery capacity is now in-line with net-zero scenarios. 

“For the first time, we can, with hand on heart, say that we are potentially on the path to net zero,” Kingsmill Bond, Senior Principal at RMI, said. “We need to make sure that we continue to drive change, but there is a path and we are on it.”

And that’s really good news.

Exponential growth in renewable energy has put the global electricity system at a tipping point. What was once seen as a wildly daunting task — transitioning away from fossil fuels — is now happening at a faster pace every year. 

Based on this new research, conducted in partnership with the Bezos Earth Fund, RMI projects that solar and wind will supply over a third of all global electricity by 2030, up from about 12% today, which would surpass recent calls for a tripling of total renewable energy capacity by the end of the decade. 

Global progress in the renewable energy sector

China and Europe have been leading the way in clean energy generation, but the deployment of renewable energy has also been widely distributed across the Middle East and Africa. 

Research from Systems Change Lab shows that eight countries (Uruguay, Denmark, Lithuania, Namibia, Netherlands, Palestine, Jordan, and Chile) have already grown solar and wind power faster than what is needed to limit global warming to 1.5°C, proving that a swift switch to renewable energy is not only feasible — it’s entirely achievable. 

In order to make that switch, globally, wind and solar need to grow from 12% to 41% by 2030. Denmark, Uruguay, and Lithuania have already achieved that increase in the span of eight years.

Meanwhile, Namibia, the Netherlands, Palestine, Jordan, and Chile have grown solar and wind energy at sufficient rates for five years...

The economic impact of climate progress

Not only is this an exciting and unprecedented development for the health of the environment, but this rapid transition to clean energy includes widespread benefits, like jobs growth, more secure supply chains, and reductions in energy price inflation. 

This progress spans both developing and developed countries, all driven to accelerate renewables for a number of different reasons: adopting smart and effective policies, maintaining political commitments, lowering the costs of renewable energy, and improving energy security. 

And with exponential growth of clean energy means sharp declines in prices. This puts fossil fuels at a higher, uncompetitive cost — both financially and figuratively. 

RMI suggests that solar energy is already the cheapest form of electricity in history — and will likely halve in price by 2030, falling as low as $20/MWh in the coming years. This follows previous trends: solar and battery costs have declined 80% between 2012 and 2022, and offshore wind costs are down 73%."

Im soooooo hungry i neeed.... gaming trivia. tO live 😺

i mostly just have TF2 trivia, as its history has always been something ive always been fascinated with, so i hope these suffice:

The Pyro's Beta Head: While 8 of the 9 classes had their heads redone throughout development (to better show off Valve's new facial flex system), only the Pyro was left untouched, leaving them as the only class to still have their beta head.

Reference Posing Medics: In "Trailer 2", there are two Medics who are in their reference pose, during the first-person sequence of the Scout running through RED's base. While their role isn't clear, one likely theory is that they were meant to be camera positions for shots that were ultimately removed, in favour of the Scouts perspective, and Valve just forgot to remove or hide them. The second Medic even turns to look at the Scout as he runs by, maybe further proving their original purpose.

The Teaser Corkboard: While we don't have a clear idea as to what Valve had been planning with the "Teaser Corkboard", one likely theory is that it was created for the proposed update that would've included both Asteroid and Cactus Canyon, due to the few mentions of "Future", the blueprint of the rocket engine from Half Life 2 Episode 2, and Poopy Joe. Also worth noting, the two posters that were added with the corkboard share similar styles Asteroid and Cactus Canyon.

The Balls of Steel Taunt: Originally, The Love & War update was meant to include a lot more taunts than what ultimately shipped. One of the few to get scrapped is a taunt called "Balls of Steel", where the initiator would dare other players to kick them in the groin. While we don't have footage of this taunt, we do have voiceline files that reference the taunt's intention, as well as the name. The few files that remain were reused for other contexts, such as the Soldiers Conga taunt, where his "Ooh!" and "Ahh!" lines were originally his pain sounds for the taunt.

A couple of points of note…

…from rewatching a bunch of old 80s movies:

While the "evil developer" has been a regular Hollywood villain since the 30s and 40s, it really seemed to have peaked in the 80s.

Given various factors, I'm surprised it hasn't seen a resurgence (though this gets to that "modern villain" vs. "postmodern villain" distinction).

THE POLAROID WORKS

[jcmarchi]

Students strive for “Balance!” in a lively product showcase

New Post has been published on https://thedigitalinsider.com/students-strive-for-balance-in-a-lively-product-showcase/

Students strive for “Balance!” in a lively product showcase

On an otherwise dark and rainy Monday night, attendees packed Kresge Auditorium for a lively and colorful celebration of student product designs, as part of the final presentations for MIT’s popular class 2.009 (Product Engineering Processes).

With “Balance!” as its theme, the vibrant show attracted hundreds of attendees along with thousands more who tuned in online to see students pitch their products.

The presentations were the culmination of a semester’s worth of work in which six student teams were challenged to design, build, and draft a business plan for a product, in a process meant to emulate what engineers experience as part of a design team at a product development firm.

“This semester, we pushed the six teams to step outside of their comfort zones and find equilibrium between creativity and technical rigor, all as they embarked on a product engineering process journey,” said 2.009 lecturer Josh Wiesman.

Trying to find a balance

The course, known on campus as “two-double-oh-nine,” marks a colorful end to the fall semester on campus. Each team, named after a different color, was given mentors, access to makerspaces, and a budget of $7,500 to turn their ideas into working products. In the process, they learned about creativity, product design, and teamwork.

Various on-stage demonstrations and videos alluded to this year’s theme, from balance beam walks to scooter and skateboard rides.

“Balance is a word that can be used to describe stability, steadiness, symmetry, even fairness or impartiality,” said Professor Peko Hosoi, who co-instructed the class with Wiesman this semester. “Balance is something we all strive for, but we rarely stop to reflect on. Tonight, we invite you to reflect on balance and to celebrate the energy and creativity of each student and team.”

Safety first

The student products spanned industries and sectors. The Red Team developed a respirator for wildland firefighters, who work to prevent and control forest fires by building “fire lines.” Over the course of long days in challenging terrain, these firefighters use hand tools and chainsaws to create fire barriers by digging trenches, clearing vegetation, and other work based on soil and weather conditions. The team’s respirator is designed to comfortably rest on a user’s face and includes a battery-powered air filter the size of a large water bottle that can fit inside a backpack.

The mask includes a filter and a valve for exhalations, with a hose that connects to the blower unit. Team members said their system provides effective respiratory protection against airborne particles and organic vapors as users’ work. Each unit costs $40 to make, and the team plans to license the product to manufacturers, who can sell directly to fire departments and governments.

The Purple Team presented Contact, a crash-detection system designed to enhance safety for young bicycle riders. The device combines hardware and smart algorithms to detect accidents and alert parents or guardians. The system includes features like a head-sensing algorithm to minimize false alerts, plus a crash-detection algorithm that uses acceleration data to calculate injury severity. The compact device is splashproof and dustproof, includes Wi-Fi/LTE connectivity, and can run for a week on a single charge. With a retail price of $75 based on initial production of 5,000 units, the team plans to market the product to schools and outdoor youth groups, aiming to give young riders more independence while keeping them safe.

On ergonomics and rehabilitation

The Yellow Team presented an innovative device for knee rehabilitation. Their prototype is an adjustable, wearable device that monitors patients’ seated exercises in real-time. The data is processed by a mobile app and shared with the patient’s physical therapist, enabling tailored feedback and adjustments. The app also encourages patients to exercise each day, tracks range of motion, and gives therapists a quick overview of each patient’s progress. The product aims to improve recovery outcomes for postsurgery patients or those undergoing rehabilitation for knee-related injuries.

The Blue Team, meanwhile, presented Band-It, an ergonomic tool designed to address the issue of wrist pain among lobstermen. With their research showing that among the 20,000 lobstermen in North America, 1 in 3 suffer from wrist pain, the team developed a durable and simple-to-use banding tool. The product would retail for $50, with a manufacturing cost of $10.50, and includes a licensing model with 10 percent royalties plus a $5,000 base licensing fee. The team emphasized three key features: ergonomic design, simplicity, and durability.

Underwater solutions

Some products were designed for the sea. The Pink Team presented MARLIN (Marine Augmented Reality Lens Imaging Network), a system designed to help divers see more clearly underwater. The device integrates into diving masks and features a video projection system that improves visibility in murky or cloudy water conditions. The system creates a 3D-like view that helps divers better judge distances and depth, while also processing and improving the video feed in real-time to make it easier to see in poor conditions. The team included a hinged design that allows the system to be easily removed from the mask when needed.

The Green Team presented Neptune, an underwater communication device designed for beginner scuba divers. The system features six preprogrammed messages, including essential diving communications like “Ascend,” “Marine Life,” “Look at Me,” “Something’s Off,” “Air,” and “SOS.” The compact device has a range of 20 meters underwater, can operate at depths of up to 50 meters, and runs for six hours on a battery charge. Built with custom electronics to ensure clear and reliable communications underwater, Neptune is housed in a waterproof enclosure with an intuitive button interface. The communications systems will be sold to dive shops in packs of two for $800. The team plans to have dive shops rent the devices for $15 a dive.

“Product engineers of the future”

Throughout the night, spectators in Kresge cheered and waved colorful pompoms as teams demonstrated their prototypes and shared business plans. Teams pitched their products with videos, stories, and elaborate props.

In closing, Wiesman and Hosoi thanked the many people behind the scenes, from lab instructors and teaching assistants to those working to produce the night’s show. They also commended the students for embracing the rigorous and often chaotic coursework, all while striving for balance.

“This all started a mere 13 weeks ago with ideation, talking to people from all walks of life to understand their challenges and uncover problems and opportunities,” Hosoi said. “The class’s six phases of product design ultimately turned our students into product engineers of the future.”

Hm

Something that kinda bothers me with trimax vs tristamp is the framing of Choice

In tristamp, it's framed as this whole big thing where he has to choose between humans and plants. "Who's side are you on?" Repeated over and over again, & he continues to not give an answer because he doesn't WANT to choose. Which in and of itself, I think this is narratively interesting, but like...

Then I think about what the big Choice is in trimax, & it feels kinda cheap in comparison.

Bc see, the Choice in trimax is over whether he should ever take a life. Wolfwood says it, Legato forces it, even fucking Nebraska Dad says it. Someday, Vash is going to have to make that choice whether he wants to or not. He spends over a hundred chapters running from this, REFUSING to choose one life over another, citing that all life is sacred... he really, truly believes this, and he really, truly wants to live by this.

But sometimes in this hell of a world, you really do have to make a choice. And in the end, he's forced to make that choice. One Time, he chooses to kill in order to save someone else's life. It happens only when his hand is really truly forced, but it Happens. He kills someone, and it nearly destroys him.

And we see this during the time where the earth forces have gotten the order to bomb Gunsmoke to combat Knives, Despite people telling them that they've got plans in motion to combat him without killing a great many people. Bc the people on earth many many miles away are more concerned with risk avoidance, so they're willing to accept killing a Lot of people in order to remove the uncertainty & risk to a great many more.

Zoom back in on Vash. He literally passes out from the mental agony of it & goes into a fever dream of all the people he knows that has died. The man he killed was an awful person, caused so much harm to both Vash and many many more people. Objectively, it should not have been a hard decision.

But for Vash, it was.

And that's what really gets me about it all. Vash is a staunch pacifist. He sticks to this despite people telling him over and over again to give up, to just accept that he has to kill people sometimes... And he eventually learns that they were kinda right in the end, but Even Still, after all is said and done, he STILL refuses to give up on any life he could possibly save.

This framing of the Choice is really, truly moving to me. It's a key part of what really made trimax Hit for me.

So tying it back in with tristamp's framing of choice... idk, it just feels kinda cheap in comparison. In trimax, Vash never really has any doubts about the plant vs human thing (aside from when he was a kid, post-tesla). He knows he's a plant. He knows a lot of humans wouldn't accept him for that. He knows a lot of humans would Fear him for that. But he still loves them and never once wavers in his pursuit for love & peace.

Overall, I just really enjoy the framing of moral questions in trimax more, I guess.

Okay on the topic of crack treated seriously crossover isekai with mdzs, I've been batting about the daycare attendant from fnaf getting reborn into... Someone.

My first thought was obviously wwx, cuz main character, excellent wild card. I considered lxc, all smiley with a heavy heart and too much responsibility trying to care for everyone even as it ruins him. I considered NHS or jgy for that manic rodent customer service energy, I considered xy for his demonic cultivation and intensity, even jyl if you really wanted to lean into the crack energy, and also Moon snapping would be Excellent crouching tiger energy.

I also considered jc.

The thing about the robot DA, if you don't know,

Half is Sun, a frustrated, overworked, sarcastic mf dealing with his alter ai going insane and trying to kill/kidnap the kids they protect. He's anxiety riddled, pithy to adults, a bit of a control freak trying to scrabble together a semblance of balance in a steadily collapsing situation while trying to maintain himself while being terminally neglected. His sanity is hanging by a thread.

Its alternate, Moon, appears whenever it's naptime - ie, when the lights go out. Moon is an uncanny security guard of the pizza plex (imagine a giant themed mall slash party venue that fails basically every osha compliance) that acrobatically hunts down anything that moves when the other animatronics (basically tortured androids let's be real) are in recharge. Moon is corrupted by a semi computer semi haunted magic virus that makes him evil. Sun is left the responsibility of keeping it locked up in his head by never, ever, resting, or by being in the dark.

By the end of the games, sun and moon, the DA, is a shell of his former self. Despite being a multi million investment as a highly marketed, one of a kind animatronic with a worryingly lifelike ai (or two), the DA is abandoned by its creators and left to rot in the slowly crumbling ruins of the daycare, along with the half destroyed and monstrous forms of its fellow animatronics who aimlessly, sightlessly roam the halls. Sun is huddled in the last beam of light from a jacked generator, and when that finally dies moon is reduced to little more than a manmade beast in the dark as they too slowly run out of power, their powerful battery long stolen and grafted into someone else. Their kingdom boarded up and half destroyed, their own private apocalypse they cannot escape, the DA begs the next person he sees for a total reboot. The combined personality, eclipse, is a gentle and naive thing unable to perceive the reality of its situation. Until it runs out of power, it will be placid and calm, lost in its illusion of the past. It is, essentially, requested euthanasia. It's the kindest send off anything else in the pizza plex gets.

So, a snarky, bitchy guy with huge abandonment issues sick of trying to corral unruly kids without reward, constantly overlooked and frankly neglected in favour of the more successful and popular siblings, with deep rooted trauma about losing his core, too much responsibility and no support, desperately trying to keep himself from lashing out and causing irreparable damage and kinda failing? Who just wants to play stupid games and stop having to shoulder everything himself? Fiercely protective of children but also not immune to pettiness?

Yeah, at that point it's not even a question. Let's give jc an identity disorder and a crippling fear of water.

How does an engine contribute to a car's powertrain?

The powertrain in a vehicle is the system responsible for generating power and delivering it to the wheels to propel the vehicle forward. The operation of a powertrain can vary depending on whether the vehicle is powered by an internal combustion engine (ICE) or an electric motor (in the case of electric vehicles). Here's a general overview of how a powertrain works in both types of vehicles:

Internal Combustion Engine (ICE) Vehicle - Combustion Process: In an ICE vehicle, the powertrain starts with the combustion process in the engine. Fuel (gasoline or diesel) mixes with air in the combustion chamber and is ignited by spark plugs (in gasoline engines) or compression (in diesel engines).

Power Generation: The combustion process generates energy in the form of mechanical power, causing pistons to move up and down within the cylinders of the engine. This motion drives the crankshaft, converting linear motion into rotational motion.

Transmission: The rotational motion from the crankshaft is transmitted to the transmission, which consists of gears that allow the driver to select different ratios (speeds). This enables the engine to operate efficiently across a range of vehicle speeds.

Drivetrain: The transmission sends power to the drivetrain components, including the driveshaft, differential, and axles, which transfer power to the wheels. The differential allows the wheels to rotate at different speeds, enabling smooth turns.

Wheel Movement: The power transmitted through the drivetrain causes the wheels to rotate, propelling the vehicle forward or backward depending on the gear selection and throttle input from the driver.

Electric Vehicle (EV) -

Battery Pack: The primary source of power for the EV, storing electricity in chemical form.Powers the electric motor and provides electricity for all electronic devices within the EV.

Battery Management System (BMS): Monitors battery cell conditions, including voltage, current, temperature, and state of charge (SoC).It protects the battery against overcharging, deep discharging, and overheating and helps balance the charge across cells. Ensures optimal performance and longevity of the battery by regulating its environment.

Inverter: Converts DC from the battery pack into AC to drive the electric motor.Adjusts the frequency and amplitude of the AC output to control the motor’s speed and torque. Critical for translating electrical energy into mechanical energy efficiently.

Onboard Charger: Facilitates the conversion of external AC (from the grid) to DC to charge the battery pack. Integrated within the vehicle, allowing for charging from standard electrical outlets or specialized EV charging stations. Manages charging rate based on battery status to ensure safe and efficient charging.

DC-DC Converter: Steps down the high-voltage DC from the battery pack to the lower-voltage DC needed for the vehicle's auxiliary systems, such as lighting, infotainment, and climate control. Ensures compatibility between the high-voltage battery system and low-voltage electronic components.

Electric Motor: Converts electrical energy into mechanical energy to propel the vehicle. It can be of various types, such as induction motors or permanent magnet synchronous motors, each offering different efficiencies and characteristics. Typically provides instant torque, resulting in rapid acceleration.

Vehicle Control Unit (VCU): The central computer or electronic control unit (ECU) that governs the EV's systems. Processes inputs from the vehicle’s sensors and driver inputs to manage power delivery, regenerative braking, and vehicle dynamics. Ensures optimal performance, energy efficiency, and safety.

Power Distribution Unit (PDU): Manages electrical power distribution from the battery to the EV’s various systems. Ensures that components such as the electric motor, onboard charger, and DC-DC converter receive the power they need to operate efficiently. Protects the vehicle's electrical systems by regulating current flow and preventing electrical faults.

In both ICE vehicles and EVs, the powertrain's components work together to convert energy into motion, enabling the vehicle to move efficiently and effectively. However, the specific technologies and processes involved differ significantly between the two propulsion systems.
