i wonder whether (and how) they can do it better than the explosive lens of the fission primary. I mean they have to do it better as otherwise there wouldn't be need for the fission primary.
- laverya 5y agoTo me, this has an obvious answer - size/weight. A fission primary is in the 50-150kg range, and can spark quite a bit of a fusion secondary at once. How many tons of pistons would you need for the same effect?
- trhway 5y agoi meant the explosive lens of the primary, not the primary itself. The lens is formed by the shock waves of normal explosives moving at 10km/s. We know that that isn't enough to spark the fusion. Thus the question - can their pistons generate the better dynamics than the explosive lens? They have to in order to spark the fusion. If they can - then how?
- bobsmooth 5y agoExplosives are single use. GF's promotional videos say one fusion reaction per second.
