Tesla Powerwall

I wonder how these things stack up with existing "house UPS" systems. I imagine Tesla has learned a thing or two about batteries and has more up-to-date tech than most home UPS systems but I'd do some research along those lines before I jumped into it.


Because if you wanted solar panels into a battery that could run your house, you could have done it 10 years ago. Did we cross some technological barrier or is this just basically like Apple claiming they invented an idea that had been around for years, but now has rounded corners?

On the UPS concept yes. Still need an inverter, but yes, the concept could act as a UPS, and it could be charged via commercial power instead of solar.

From a tech perspective, the tech has changed a lot with lithium. We have the old lead / acid based plants in all our central offices. These are 48 volt power plants with big ass batteries. When they charge, they generate hydrogen and require a lot of maintenance. the hybrid and electric car batteries has introduced new tech.

BUT... I still do not believe Lithium is the answer. The answer will be some sort of super capacitor, perhaps even made from grown organic carbon with lighting fast recharge capabilities. There will be a time that we will look back Batteries as the old and very stupid tech.

Graphene Supercapacitors are one of the area's to keep an eye on.
