Hey RW. I too have a system to cheaply, very cheaply produce Hydrogen AND methane from water...... and I have the same problem, need to get a team together or scientists, engineers and funding.... together I bet you and I have some realistic cheap solutions to fuel everything, and we will be met with much resistance.
What can we do? Funding is the only real hurdle here for any of us Hydrogen heads :)
Do you know the answers to the following questions?
How much electrical energy does it typically take to disassociate H2O thru the electrolysis process?
How much electrical energy does it typically take to disassociate H2O by using an RF signal thru the RET process?
