New solar panels suck water from air to cool themselves down

May 28th, 2020 at 11:17 am » Comments Off

Intense summer sun can spike temperatures of solar panels, causing their electrical production to plummet. Like humans, solar panels don’t work well when overheated. Now, researchers have found a way to make them “sweat”—allowing them to cool themselves and increase their power output. It’s “a simple, elegant, and effective [way] to retrofit existing solar cell […]

Peer-to-peer highway EV charging would use telescoping cables between moving cars

May 26th, 2020 at 9:30 am » Comments Off

Imagine a future where your EV was getting low on charge ­on a highway road trip – so you deploy a telescoping charging cable to another EV and borrow a few kilowatt-hours. An engineering professor at the University of Florida believes it’s not far-fetched. We’ve seen a host of mobile EV charging van concepts. And […]

A no-brainer stimulus idea: Electrify USPS mail trucks

May 26th, 2020 at 9:27 am » Comments Off

Electric vehicles for the US Postal Service would reduce noise, air, and carbon pollution in every community. With the US trapped in a historic lockdown, everyone agrees that enormous federal spending is necessary to keep the economy going over the next year and beyond — and everyone has their own ideas about how, exactly, that […]

Fusion energy gets ready to shine – finally

May 7th, 2020 at 11:06 am » Comments Off

Three decades and $23.7 billion later, the 25,000-ton International Thermonuclear Experimental Reactor is close to becoming something like the sun. UNTIL 1920, HUMANS had no real sense of how the sun and stars create their vast amounts of energy. Then, in October of that year, Arthur Stanley Eddington, an English astrophysicist, penned an essay elegantly […]

The most important US energy chart of the year is out: 8 big takeaways

April 27th, 2020 at 12:10 pm » Comments Off

  The numbers represent “quads” or quadrillion BTUs, with the total consumption totalling 100.2. Conveniently, you can pretty much interpret the below numbers as a percentage of total US energy usage. 1. Overall energy usage declined by 1% That’s significant. Compare to 2018 below and you can see: The biggest shock to most people is […]

Energy-harvesting design aims to turn Wi-Fi signals into usable power

April 12th, 2020 at 1:25 pm » Comments Off

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone. Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic […]

This company wants to turn your windows into solar panels

April 11th, 2020 at 12:11 pm » Comments Off

Ubiquitous Energy solar glass San Francisco (CNN Business)What if every window in your house could generate electricity? One Redwood City, California-based startup thinks its technology can achieve that by transforming the way solar power is collected and harnessed. Ubiquitous Energy has developed transparent solar cells to create its ClearView Power windows, a kind of “solar […]

If you’re living with an electric car, what type of house you have is more important than you think

April 8th, 2020 at 11:19 am » Comments Off

If you live in a flat or don’t have off-road parking, running an electric vehicle may be more difficult than you think, writes Sean O’Grady If there is one hard lesson I have learned about living with an electric car, it is that it is not for everyone. At least not for now. Sure, there […]

The coronavirus is showing us how clean the air can be if electric cars were the norm

March 31st, 2020 at 11:18 am » Comments Off

With all the loss of lives and financial destruction that the coronavirus has brought us, it’s hard to look at silver linings from this crisis, but there’s one that’s becoming obvious: cleaner air. It might not last for long, but it’s giving us a glimpse at what we could experience if the world was to […]

Researchers create stretchable super capacitors for our next wearables

March 31st, 2020 at 11:09 am » Comments Off

Carbon nanotube forests improve the stretchable supercapacitor’s performanceDuke University The supercapacitors still functioned well when stretched to eight times their original size. Imagine a new type of supercapacitor that can be repeatedly stretched to eight times its original size, yet still retaining its full functionality. Only after 10,000 cycles of charging and recharging does it […]

Long narrow wires carry heat with little resistance

March 28th, 2020 at 9:51 am » Comments Off

Smooth-walled wire traps high energy phonons, low energy phonons carry heat. Tiny wires may boost heat flow. Getting rid of heat is one of the central challenges with modern technology. It doesn’t matter whether the technology is a high-end server CPU or some pathetically anemic processor in a no-brand set-top box—someone has had to think […]

Era of wireless charging for electric vehicles is coming

March 22nd, 2020 at 11:37 am » Comments Off

  Wireless charging for electric vehicles is today’s most cutting-edge technology. Why? It is the most efficient, futuristic, scalable–in short–awesome alternative we have to gasoline. While tech giants such as Uber are placing their bets on autonomous cars, major key players such as Jaguar Land Rover are mass-producing electric cars. What’s more, Fordis releasing fully-electric […]
