Comment on Could AI robots with lasers make herbicides – and farm workers – obsolete?parent

Lasers are even more energy-intensive than pesticides...

Even if that's true, perhaps having a small-ish solar farm near the crops would allow the bots to recharge onsite?

That might be(?) less energy-intensive than manufacturing pesticides remotely and shipping them to the fields.

I was imagining in my head kind of real time conversion from sunlight to a laser. Maybe not the practical solution, but I do wonder how doable would that be.

Back of the napkin with GPT assistance seems around 2 square meters needed to power a 150W laser.
