Solar Storage Via Hydrogen [RE-wrenches]

[Matt Lafferty]

Scott:

A contact you might want to make with regard to H20-H2 conversion is Michael
Lafferty (yes, my dad).  He can be e-mailed at Michael_Lafferty at ferris.edu .

What a bummer to only get $.02/kWH!  Keep looking.   This industry needs
answers!
