Certainly a cool achievement and something to be proud of. Maybe even a very important step towards real usable fusion power plants.
But:
> The facility’s laser system is enormously inefficient, and more than 99% of the energy that goes into a single ignition attempt is lost before it can reach the target.
So it's still two orders of magnitude off hitting break even. And that's without a suitable device to actually capture the released energy and it does not account for pellet production. For all we know, it might very well be three orders of magnitude away from a real powerplant.
That being said, making more efficient lasers and working on capturing energy might be more fruitful than trying to improve a Tokamak design. So it's good to have options.
- DennisP 3y agoFar more efficient lasers already exist. Their lasers are old.
- SamBam 3y agoTwo orders of magnitude more efficient?
- DennisP 3y agoFrom 0.5% to over 20%, for equivalent lasers. So they still have work to do, but not as much you'd think without accounting for the old lasers.
- deepnotderp 3y agoAre modern petawatt class lasers really 20% efficient?
