New battery tech lasts for days, charges in seconds

The super-capacitor cell is just a “proof-of-concept” but looks promising

Scientists from the University of Central Florida (UCF) have created a super-capacitor battery prototype that works like new even after being recharged 30,000 times. The research could yield high-capacity, ultra-fast-charging batteries that last over 20 times longer than a conventional lithium-ion cell. “You could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week,” says UCF postdoctoral associate Nitin Choudhary.

New batteries that mimic the human intestine could store 5 times more energy

by Peter Dockrill, Science Alert

Scientists have developed a new prototype battery inspired by the anatomy of the human intestine, and the biologically informed approach could pave the way for much more powerful energy sources for our digital devices.

The prototype – which offers up to five times the energy density of the lithium-ion batteries we use in smartphones and laptops – uses a lithium-sulphur cellinstead, and its intestine-mimicking design could finally make these energy-dense batteries long-lasting enough for commercial use.

Las Vegas streetlights are powered by your footsteps

by Steve Dent, Engadget

EnGoPlanet’s solar and kinetic energy stations also run WiFi hotspots and security cameras.

Las Vegas is famous for its lights, bright sunny days and copious pedestrian traffic. That no doubt made it the perfect place for clean tech startup EnGoPlanet to test new LED streetlights powered by both photo-voltaic panels and kinetic footstep pads. Married with a battery, the setup not only lights up the Boulder Plaza in downtown Vegas, but also powers security cameras (yep), WiFi hotspots and portable charging stations.

This battery heals itself if you break it in half

by David Nield, Science Alert

Scientists have developed a self-healing electronic device that repairs itself when broken, using a special magnetic ink to bridge gaps as wide as 3 millimeters (0.12 inches) – a new record in the field.

The technology could be used in a variety of ways, including batteries and sensors for wearables, because it works much faster than other self-healing materials and requires no external input to carry out the patch-up job. Continue reading This battery heals itself if you break it in half

An Electric Helicopter Arrives

by Steve Hanley, Clean Technica

Martine Rothblatt is not your typical person. She is the founder of Sirius satellite radio and vehicle navigation company GeoStar. When her daughter was diagnosed with a rare life-threatening form of pulmonary hypertension, Rothblatt formed United Therapeutics to market medication for others suffering from the same disease. Because pulmonary hypertension often requires a lung transplant, she next created a division of her drug company that focuses on developing artificial and transplant-able lungs from pig genetics.

But the helicopters that deliver those artificial lungs are loud and not particularly environmentally friendly, so Rothblatt decided it was time to invent the first full-size battery-powered electric helicopter to deliver the transplant-able organs more cleanly and quietly. Helicopters can burn 500 pounds of aviation fuel every hour, leaving a trail of carbon emissions in their wake. Continue reading An Electric Helicopter Arrives
