Welp, at 2 acres per hour it'll only take 3000 hours to weed my friend's farm.
I never would have thought of using lasers for weed control.

Me neither, but it makes sense. I have a propane 'weed torch' around here somewhere.
I can see this working well for the high-$$ organic crops. But it needs to scale up by a couple of orders of magnitude to be useful around here. IIRC, this company had an autonomous crawler version, pair that with a Mr. Fusion and just turn it loose in the fields. Then the number of hours won't matter 'cause it is just a robot, hhh.
>Me neither, but it makes sense.
Except won't the weed grow right back with its roots being left behind? Maybe that works fine with ag cycles.
> grow right back
I don't think so. The propane spot-weeding torches have a good record for long-term kill. I *think* the heat kills the root.
