James, The thread about the H-Cat, as an inexpensive but meaningful experiment in its base-level incarnation - raised the possibility that an automotive catalytic converter ($40 -$100) - filled with hydrogen. It could show a steady temperature gain over ambient of more than Cravens' ongoing gain of 5 degrees - essentially for years.
That kind of experiment would cost a few hundred, out-of-pocket dollars for any garage lab with hydrogen, a datalogging PC, thermocouples and about a square meter of space to spare. To actually burn the hydrogen is counter-productive for proving gain. From: James Bowery How expensive is it to replicate? http://www.infinite-energy.com/images/pdfs/NIWeekCravens.pdf Cravens experiment was ongoing at infinite COP for 2.5 months before NI Week, and he indicated that he would keep it going (that needs to be confirmed). If true, this one has been ongoing for almost 10 months at infinite COP.
