So liquid H is cheaper than He? Just out of curiousity, how do they compare with LN2? I have no idea what LH costs. I have seen estimates of $4 a kg. produced. Sales at low volume would probably be double that. It boils at about 20K. Its density is about .071 kg/l. It takes 50 KWh to produce a kg o...

In spite of their double talk about frames of reference, this still violates conservation of momentum. Draw a box around the system and ignore what is inside. Nothing comes out, except a little heat. Without some outlet for the momentum, there can be no thrust. Here is a paper which uses a different...

Read this article by Jan S. Brzosko. http://www.physicsessays.com/doc/s2007/PF50-7-_03_07-CurrentTrends-bk.pdf From page 25, the best shot is the blue line with 50kJ of energy. With D-D, this gave about 9e10 neutrons. Multiply by 2 fusions/neutron * 2.7 MeV /fusion * 1.6e-13 J/Mev, we get 0.78 Joul...

Smells like BS to me. It is advocated by Eric Lerner of Lawrenceville Plasma Physics, Inc., see http://www.lawrencevilleplasmaphysics.com . The wikipedia page http://en.wikipedia.org/wiki/Eric_Lerner mentions that he does not believe in the big bang and has its own theory of cosmology. Google maps i...

Re: What will it take?
Dr Carlson, from what you know about the WB-7 right now, do you believe it could produce results that would convince you that it was worth spending ~$200M attempting to build a net power device? Not just for scientific discovery, but specifically because you thought net power just might be possible...

The available descriptions of polywell operation are neither complete nor consistent. Some explanations contradict other explanations or the laws of physics. We're just trying to find a description that could describe a working machine. This has also been a source of frustration to me. See http://w...

At 10 keV? I don't have the specific voltage for that model, but the website says typically they are 80-180 Kev. They are simple accelerators with metal hydride targets, so it is much more likely that the accelerated hydrogen hits the metal rather than the hydrogen in the target. Of course, there i...
