You don't have to be a farmer to appreciate the awesomeness that is the 'Weedmaster' from Fabian Zimmerli. The 'Weedmaster' is a methanol-powered robot designed to remove the weeds from crops.
'Weedmaster' from Fabian Zimmerli would reduce the number of herbicides and human man hours currently required to pick weeds. Cutting out the herbicides would make our food safer to eat and farmers would save money by not having to hire hands to do the backbreaking job of weeding out rows of crops. Check out the Weedmaster above.
