I think one of the little sterling models would make an interesting reactor platform where the Ni foam or skeletal cat is captive at the bottom of the cylinder and the hydrogen gas is sealed inside like the Papp engine – a sort of hybrid between only using exotic gases like Papp and the present Rossi or Mills device using pressurized gas with Ni powder or skeletal cat. The shaft of the sterling engine would be externally driven to vary the pressure and then measure the temp variation of the cooling system. Fran

The efficiency of the system is better with the low pressures achieved by condensing the steam and not many would want to have to refill the coolant as often as would be required to go long distances. Also, if coolants other than water are used, it would be difficult to release them into the atmosphere. A closed water system appears ideal and the LENR device could be running in idle when the vehicle is not in use to keep the water from freezing during cold periods since the cost of doing so would be negligible.

A quick back of the envelope calculation reveals a (very rough) amount of water usage of 20 L / hr, which is not too much to carry on board. A 40 L "gas tank" would hold enough water for about 2 hours, after which it would need to be refilled with a garden hose. Any radiator used would extend this. (This assumes a high temp. of 400 ºC, and a Carnot efficiency of 57%). Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
