### Comment:
It lets them bring supercapacitors and ultracapacitors in house. The whole reason Tesla purchased is because of supercapacitor tech.

### REPLY:
What’s the point of that? I’m not saying it’s wrong, but super capacitors are known for their high power density, but low energy density, and high leakage current. Surely houses would value high energy density and low leakage current batteries over super capacitors? What am I missing?
