Inhabitat's Week in Green: Tesla's Powerwall and the 2015 Milan Expo
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Tesla capped the week off with the announcement everyone's been waiting for -- its new $3,500 10kWh Powerwall home battery is coming soon. All eyes were on Elon Musk this past week as he took the stage to show off the stylish new battery that could help take your home off the grid. The internal combustion engine has been around for more than 150 years, and for most of that time it has run on petroleum, which isn't exactly a friend of the environment. But what if we removed gas from the equation and replaced it with something more harmless? Audi recently invented a synthetic "e-diesel," which is made with water, CO2 and electricity derived from renewable energy sources. The new fuel could revolutionize the car industry and help reduce carbon dioxide emissions.
Tesla wants its Powerwall to save the grid and your bank account
Our lust for electricity is insatiable. At night we connect a hydra of wires to our phones, computers, smartwatches and tablets. They sip at the electrons being pumped into our homes, filling their batteries to be ready for another day without being tethered to a wall. Tesla wants your house to be ready. Ready for power outages and heat waves. The company says its Powerwall home battery system can untether your home from the power grid for a few hours, which might not sound like much, but could have huge implications for the way we power our lives.
