Duh! Why do these pennies take so long to drop these days? Be vapour in the reactor looks like it might be a supplement to the Boron fuel. The natural isotopes are Be7, 9, and 10. If the most prominent reaction is proton capture, Be7->B8->2He, ie more aneutronic fusion. Be9 and 10 just produce stabl...

For some months at least the plan has been to try a tungsten electrode before Beryllium. This doesn't seem to me to be a change of plan. I guess the question is why do tungsten at all. Maybe they hope for better data which will attract more funds.

Today emissions are 35 bn tonnes CO2. That's from roughly 2bn industrialized inhabitants. So suppose 10bn people emit 5 times that. At the moment CO2 is rising about 2.8 ppm per year. In the worst case scenario, it would be rising at 14 ppm per year. It would rise linearly, because CO2 per head has ...

The gravitational behavior of antimatter is still unknown...... I read about experiments being set up to test that years ago. Not seeing a followup I presumed a 'null' result of antimatter acting exactly like normal matter to within the precision of the experiment. I keep looking, but AEGIS has not...

I had intended to post this reference in respect of the AEGIS comment. EPL (Europhysics Letters) Volume 94 Number 2 M. Villata 2011 EPL 94 20001 doi:10.1209/0295-5075/94/20001 Abstract The gravitational behavior of antimatter is still unknown. While we may be confident that antimatter is self-attrac...

Couple of points: 1. I'm far from a physicist, but I recall that 'Hawking Radiation' is caused by gravitational effects near an event horizon tearing virtual particle pairs apart. So the assertion that virtual particles don't gravitate is at least suspect. 2. The AEGIS experiment at CERN is working ...

Apropos various remarks: 2 kW/kg was rather arbirary and used to calculate N/kg, aka acceleration. So higher thrust per watt reduces the specific power requirement. Higher thrust/Watt may be entirely sensible, per others comments. Also, do you agree the proposed skunkworks generator is about 1kw/kg?...

Although there is massive cause for scepticism on these results, it's amusing to do some arithmetic on what it might mean if true. 5mN per kW combined with 2kW/kg, gives an acceleration of 10^-2 ms^-2. That's about 10^-3 light years per year per year. On a simple newtonian calculation, accelerating ...

Hello Talk-Polywell! My first reply after much read-only access, and it is of course a begging letter..! LPP are close to both their target for funding, and the end of their indiegogo campaign - ends midnight today July 5th. https://www.indiegogo.com/projects/focus-fusion-empowertheworld--3 For me, ...
