Global Warming, er Climate Change is a National Security Threat

Quote:What about the new Tesla battery that powers your house and that they claim is infinitely scalable?   They're pricing it at $3,500 for the 10KWh model. 

 

"Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery."

This makes solar panels much more viable.  
 

So now you're believing corporate press releases? Lead-acid batteries can already do what these do and are cheaper. This is just a big Lithium Ion battery. There's no technological breakthrough here.


 

And $31,000 for nine batteries buys a lot of electricity, and that doesn't even include the cost of the solar panels or the DC/AC converter. At 8% interest (a good mutual fund pays more) you'd get over $200 per month from $31,000 without ever dipping into the principal.
