How many solar panels (and/or windmills) do you think you would need to keep up with your daily kWh usage?

What a cool article. All steps taken towards solar energy are great steps. I think that though there are hurtles, electric/solar power is the way to go!

Thanks for the information!

I like that idea James. A rotating battery stock would provide safety and check points for the batteries to ensure no bomb-like capability. And, since the companies are talking about leasing the batteries anyway, well, it could turn into a modernized convenience store eh? Instead of stopping to refuel, there is a certified person who comes out and changes your battery, kind of like the old days (40′s). But that could get complicated.

Thanks for your comment. It’s good to keep blowing people up in mind when considering new technology.

Let’s assume you have the battery.
The car it is in will draw 12KW/HR for 4 hours then need recharge. That’s 48,000 watts input for 1 hour to recharge. A ten min. recharge would require 6 times that rate of charge. That’s substation size charging stations.
Volts times amps= watts!!!!
I don’t want to be anywhere near that thing! One slightly loose connection or corrosion and you have a bomb.
Better to have exchangeable batteries and lower recharge rates.
