The energy usage should be minimal - it doesn't take much power to burn a leaf. If you pull it behind a tractor, you need to hire someone to drive the tractor.

If you pull it behind a tractor, you need to hire someone to drive the tractor. This defeats the purpose of an autonomous weeding system.

If they're weeds, they're actively growing, so they are trapping a lot of moisture that could make it hard to burn. If the weeds are a problem, then they're going to be growing. Many weeds, too, will continue to grow, even if their leaves are damaged or removed.
- throwaway09223 6y agoI think we might be using different definitions of "burn." I mean burnt by radiation so it no longer photosynthesizes -- in some plants this can happen simply from overexposure to sunlight. It's not necessary to turn it to ash. A machine continually damaging cotyledons in emerging seedlings would go a long way. That's part of the advantage of a continually running weed killer.
