Hot Fusion finally breaks even -- far, far behind "cold fusion"
Fernando Lins from Brazil brought this to my attention.
Nature Reports: Fuel gain exceeding unity in an inertially confined fusion implosion (February 12, 2014)
- Ignition is needed to make fusion energy a viable alternative energy source, but has yet to be achieved. A key step on the way to ignition is to have the energy generated through fusion reactions in an inertially confined fusion plasma exceed the amount of energy deposited into the deuterium–tritium fusion fuel and hotspot during the implosion process, resulting in a fuel gain greater than unity. Here we report the achievement of fusion fuel gains exceeding unity on the US National Ignition Facility using a ‘high-foot’ implosion method, which is a manipulation of the laser pulse shape in a way that reduces instability in the implosion. These experiments show an order-of-magnitude improvement in yield performance over past deuterium–tritium implosion experiments. We also see a significant contribution to the yield from α-particle self-heating and evidence for the ‘bootstrapping’ required to accelerate the deuterium–tritium fusion burn to eventually ‘run away’ and ignite.
This is elaborated in TheHindu:
But "cold fusion" or LENR as it is now more frequently called, still mislabeled "junk science" by mainstream science, achieved overunity long ago, and the leading companings bringing it to market are in the region of 6-10x. The hot fusion world is still a decade and many more billions of dollars away from anything commercial, while three LENR companies are looking to go commercial (product available) in 2014. Rossi's E-Cat, Defkalion, and Brillouin.
