There was a machine at bit like this about 7/8 years ago at a show at Newark. Mounted on the back of a tractor. Seem to recall it consumed a huge amount of energy to heat the foam up. Cost about £45k then iircHas anyone else heard about Foam weeding - I was sent a link this week:
https://www.weedingtech.com/why-foamstream/foamstream-vs-alternatives/
Quote from their website - "Foamstream requires fewer treatment cycles than any other herbicide-free solution. Its treatment cycles are even comparable to those of glyphosate. "

That seems to be the problem commercially - as water is at boiling and imagine boiling 3000l of water!
Boiling water is probably more hazardous than roundup!
