[ RadSafe ] Rational Thought

Tue Oct 4 07:05:09 CDT 2011

Chris,

Ever heard the words "efficiency"? If you ever heard anything about hydrogen production by electrolysis and its efficiency (it has to be burnt to deliver energy) or the overall efficiency of pumped storage - please enlighten us. I know obviously a little more about this than you! 

Best regards to everyone except our raman spectroscopist!

Franz
