flowCUT solarmower by jake griffiths from uk
designer's own words:
Had enough of pushing a heavy lawnmower across your back garden when you have better things to do with your weekends? The flowCut solarmower tackles this laborious task by using sunlight and rainwater. All you have to do is leave the flowCut on you're lawn, let it soak up the sun, and the photovoltaic panel will power the engine and rotary blade, allowing you to put your' feet up. The flowCut detects when to turn and stop with the use of a laser sensor at the front and rear. It also tackles the task of feeding the lawn by collecting rainwater in a compartment filled with natural grass nutrients... With the flowCut solarmower the grass is always greener!
