Ah that makes sense. I had no idea the lasers were that inefficient. Still it's not an inherent feature of the problem. But maybe getting the fusion reaction to self-sustain is the easier thing to solve.
- nine_k 4y agoLasers are likely 10% efficient, not 1%, but it's still an order of magnitude less than needed to break even.
- fsh 4y agoThe laser at NIF has a 0.5% efficiency [1]. Some lasers are highly efficient (for example diode lasers). High-energy pulsed lasers are usually not. [1] https://physics.aps.org/articles/v14/168 https://physics.aps.org/articles/v14/168
