It's not even close to net positive. It's more energy out than the lasers put in. But the lasers take in WAAAAY more than they put in.

What are you talking about? They put in 2MJs of energy in, and got back 3.5MJs out?

They lasers are about 1% efficient. The actual energy required is hundreds of MJ.

If your "they" refers to the lasers, the lasers put in 2mj, correct. That is not what "they" (my they) put in to the lasers.
