One doesn't often see the words dimmers and 4GHz together.
Explanation, please?

NIF has 192 beam lines, each a big pipe full of flashtube pumped
amplifiers. The input to each line is a fiberoptic blip of light at
about 1100 nm; it makes 4 free-space passes through the slabs and
emerges at the and, goes through a tripler, and enters the target
chamber as UV. It all converges on a little gold capsule full of
tritium and stuff.

So, do you expect to see break-even in your lifetime?

I think they expect net fusion energy greater than the laser light input
to the target chamber, but that's far from wall-plug break-even. As they
like to say, they expect about as much fusion energy as there are
calories in a jelly donut.

I'd like to hook up with a sorceress, and conjur up a Zero Point
Daemon. ;-)

Cheers!
