Tesla Powerwall

Whether they’re looking to finally get off the grid for real, have a nice power-outage backup plan to increase their peace of mind, or just show off how damn futuristic they are, the Tesla Powerwall is one of the foremost technologies in modern electric power. The idea is so obvious that it’s kind of amazing we haven’t had these for decades. Paired with solar panels, the Powerwall can power an entire house on most days, and as a standalone item it provides great insurance against temporary outages due to severe weather and other natural and manmade mischief.
