If you follow me on Twitter you might have noticed I’m slightly obsessed with renewable energy. It seems like an obvious solution to some of the problems we’ve inflicted on our planet in the last 100 years or so. It’s been quite some time since I’ve managed to get enthusiastic about a new Kickstarter project, but here’s one that’s really exciting to me – Orison is a relatively affordable new battery for your home, a smaller modular alternative to the recent-ish Tesla Powerwall. This kind of energy storage allows you to buy energy from the grid when it’s at its cheapest, or sell it back to the grid when it’s at its highest, and you can store the energy from solar or wind power too. It’s exciting to think this kind of individual sustainable energy storage could be just around the corner as a mainstream solution.
