If I remember right, burning a wax candle was more efficient than this process.
Burning a wax candle is more efficient than what process?
A typical cold fusion experiment using Seebeck calorimeter
costs roughly $50,000 including all equipment, and they are run by volunteers and retired professors. Some have produced 50 to 300 megajoules in one run. They have achieved the two goals hot fusion has failed to reach for 60 years: breakeven and full ignition.
The Tokamak Fusion Test Reactor (TFTR) at the Princeton University Plasma Physics Laboratory, U.S. Department of Energy cost “about a billion dollars” to construct and $70 million a year to operate. It produced 6 megajoules in one experiment, the world record run for hot fusion.
