[ausev] hydrogen efficiency

[m. edmund howse]

The only place I've found to have access to super capacitors with some 
stock is Digikey.com.
The Univ. of Texas uses a lot of capacitors but the ones I'm familiar 
with are in the 30-50kv
range. You probably don't want them in your EV except maybe for theft 
prevention. LOL.
