I also performed a comparison that suggests that Rossi will do fine with the new design. I thought about a 1 MW thermal input ICE which should deliver around 300 kW of mechanical power on a good day. At 750 watts to a horse power I obtain an estimate of 400 HP for the equivalent internal combustion motor rating. The size of Rossi's drum is greater than the radiator required to cool down an engine of this size with air.
I think the drum in quite reasonable with this comparison as a reference.

I think I am mixing up MW electric and MW thermal. A like sized region of a commercial fission core is producing about three times this much thermal output, ~3MW. Plants of that generation are about 33% efficient so the resulting electrical output is ~1MW, which I erroneously used for the thermal number in the previous mail. So I think the thermal density Rossi describes is about 1/3 of an operating commercial LWR fission core.

That volume would accommodate ~4 linear feet of ~100 fuel rods which would produce ~1 MW. Note: I am not a nuclear engineer but I'm playing one tonight on the interwebs. Ymmv.

Please check your figures and let me know if there is an error. This is very interesting information from Rossi as, if true, his device now would fit nicely within a locomotive size tractor. It is time to do some further research into this.

This is incredible power density. Seems unbelievable how you can pack 1MW output from these dimensions. If true, this is more revolutionary than we thought. I did some rough calculations. With diameter of the cylinder at 1.2 m, the area is 1.13 m2. Assuming that the coolant pipes take up about 50% if this area, and fitting remaining area with 100 reactors. Each reactor would have a diameter of 4.2 cm. Each 4.2 cm dia. reactor would be producing 10KW. Dave, maybe you can do some simulations on if it even is possible to remove this much heat from such a reactor. Another thing. Rossi says he's shocked. Does this mean that Rossi no longer does the main development. Otherwise, How can he be shocked by something he is developing himself? Or maybe, he is shocked by the extent of his own imagination.

Andrea Rossi August 29th, 2012 at 3:05 AM Dear Dr Joseph Fine: You are perfectly right: in fact we are designing the new 1 MW plants, for hot temperature, and the dimensions will be those of a cylinder with a diameter of 1.2 m and a lencth od 0.4 m. Is shocking, I myself are surprised, but it is so. Warmest Regards, A.R. Andrea Rossi August 29th, 2012 at 9:45 AM Dear Franco: Attention: the dimensions 1.2 x 0.4 is not the surface of the surface of the reactors! Inside this drum of 1.2 x 0.4 m there are 100 reactors , each of one having about 1 200 cm^2 of surface ! I talked of the dimensions of the external container, not of the heat exchange surface ! Warm Regards, A.R. Regards, Patrick
