Given the huge weight savings in fuel, perhaps the lower efficiency of steam turbines can be lived with? The problem with generating Hydrogen on the spot is that all the Hydrogen required needs to be carried in the form of water, which once again adds a huge amount of weight, since the energy liberated in the turbine is normal chemical energy, implying much more water than conventional fuel (assuming it can't be condensed & reused once it has been through the gas turbines). All in all, my generator would be better. Energetic alphas generated through fusion as required, and used to heat in-flowing air to produce thrust in an almost conventional gas turbine. About a lb of fuel would easily take a fully laden 747-8 around the planet, non-stop. [snip] Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
