Need a link for this “claim”. Checked the science sites I frequent and no mention of it. IF sustainable fusion happened, the net should be jumping...it’s not.
As far as a “commercial device” goes...well, I think not. The following link takes you to the National Ignition facility
as one can see by the few posted pictures, a working smaller commercially available device is a long long long long way off.
I know you’re just passing along what you found, but sorry, NO SALE!
See post #21.
