Dr Hurricane unleashes FUSION POWER

Recommended Posts

 

Scientists in California have made a major breakthrough in fusion power research, but the path to unlimited clean energy remains long and difficult.

 

The scientists described the significant result – which was recorded last year at the National Ignition Facility in Lawrence Livermore National Laboratory – in a paper published in Nature on Wednesday.

Ignition is needed to make fusion energy a viable alternative energy source, but has yet to be achieved1. 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 method2, 3, 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 has to be the way forward, but it always seems like we are 30 years away.

  • The Jet Stream is coming next week, bringing Autumn with it

    It had to happen at some point, and from Tuesday next weeka0Autumn proper is going to arrive. The jet stream will be diving south, bringing low pressure systems right across the UK which means a change to much less settled and also cooler weather. Read the full update here

    Michael Fish: Autumn proper on the way

    Michael Fish returns with his latest weekly forecast, and there's a big change on the way. The weekend and start of next week will keep the sunny, warm and mostly dry weather coming before low pressure makes its move and brings a change to much more Autumnal weather.a0 Watch the video here
