Roost battery makes your dumb smoke detector smarter

If you're looking to add a bit of smart functionality to your home but aren't interested in swapping out your existing devices, the folks behind Roost might have the solution. Roost is a 9v battery that connects your "dumb" smoke alarms to your WiFi network so that alerts are shuttled off to your smartphone, where you can see if they're going off and in which part of the house the detector is located. It also eliminates low-battery chirping that starts late at night, among other things.

Gogoro teases big battery plans for smarter city travel

Gogoro teases big battery plans for smarter city travel

Power: it's something none of us can do without, both the enabling and limiting factor of everything from smartphones through to electric vehicles, and it's ripe for a revolution. Hoping to lead just that is Gogoro, startup brainchild of former HTC innovation chief Horace Luke and Matt Taylor, and coming out from the shadows today to share a few early hints about its plans "to transform energy distribution" within smart cities. I caught up with Luke to find out more, curious at indications that some new power system potentially for EVs could be on the cards.

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.

Why Chrome browser on Windows eats batteries like crazy

Why Chrome browser on Windows eats batteries like crazy

If you're a dedicated Chrome user and have noticed your Windows laptop plunging into an earlier death than normal, then you may very well blame a "feature" that was introduced way back in 2010. Though that feature made sense in a day and age when browser plugins, Java applets, and Flash dominated the Web, Chrome's high-performance system tweaking has now become a liability that Google doesn't seem to be keen on addressing quickly.
