There is no question that the fossil and uranium deposits of the planet are finite and sooner or later will be exhausted. The only question is when? Yet, because of the financial interests of the fossil and nuclear industries, the need for converting to inexhaustible energy is still being debated. This debate must end and conversion to renewable energy must start. This will not happen until it is proved that the conversion to a solar-hydrogen based economy is feasible and economical. It is for this reason that I designed the demonstration power plant described in this section.
