Helios Bluetooth headphones use solar power to juice up

Bluetooth headphones offer the distinct convenience of shedding the audio cable and allowing users to listen to their music unshackled. That convenience disappears, however, once the battery runs low, which requires you to plug them back in until there's enough power to go wireless again. Exod's Helios headphones address this by adding solar charging into the mix, allowing users to leave the device in sunlight when not in use to charge back up the internal battery, no cables necessary.

Team Sunswift sets record for EV speed over 500km distance

Team Sunswift sets record for EV speed over 500km distance

A group of Australian students has set an official world record for the fastest electric vehicle over a distance of 500km using a car they built at the university dubbed eVe and operated by team Sunswift. The record was certified by FIA, a motorsports governing body, with a new speed mark of 109.966 km/h set by team Sunswift in July. Before Sunswift reset the record, it had stood at 73 km/h for 26 years.

New solar cell is its own battery

New solar cell is its own battery

Solar power is an important part of our future, but in many ways it is still too expensive. The Ohio State University has helped lessen that issue with a new device it created -- a solar cell that serves as its own battery, doing so using a type of panel design that introduces air into the "breathing" battery.

MIT recycles old car batteries into cheap, long-lasting solar panels

MIT recycles old car batteries into cheap, long-lasting solar panels

Lead pollution is a serious issue, particularly when looked at from the perspective of thousands of old car batteries that are increasingly unneeded due to changes in the battery technologies used. Researchers at MIT have developed a new way to recycle these batteries, and rather than creating them into new car batteries, they've figured out how to make them into very efficient solar panels.

BMW i Solar Carport Concept powers i8 and home

BMW i Solar Carport Concept powers i8 and home

Plugging in an electric car to recharge often happens in the dark confines of a garage, but BMW wants to brings its u3 and i8 EV range into the light with a new BMW i Solar Carport Concept. Mounting translucent solar panels on top of a bamboo frame - the wood picked for its rapid regrowth - the carport could be entirely off-grid, BMW claims, though you'd obviously need to get enough sun.
