Comments Off on Newly-revealed Tesla solar roof patent shows the secrets behind the technology

Tesla’s solar roof tiles stand apart from other integrated solar roofing options in part because they’re camouflaged – you can’t even tell the tiles are collecting solar power. But have you ever wondered what kind of tech it took to make that happen? A new Tesla patent released this week shows how they did it. Here’s a hint: it wasn’t easy. Tesla worked with Panasonic to create a grid of solar panels that could link together without taking forever to install. On top of that, they had to create the tiles in such a way that they appeared opaque from the street but remained transparent to the sun above – all while still being as efficient as possible. To solve this problem, they created a new kind of glass with small louvers, which make the glass look opaque when viewed from below while keeping it open to sunlight.

Comments Off on Ceramatec’s new battery could power your house for pennies per KWh

Eco Factor: Inexpensive battery developed for use with on-site power generators. One of the major reasons we don’t see people opting for off-grid systems such as solar and wind generators is the high cost of batteries that are required to store all that power for low wind or sun periods. Scientists at Ceramatec have developed a new kind of deep-storage battery that when coupled with solar and wind generators can power your entire home at the rate of pennies per KWh.
