The EcoMow is a revolutionary new proto-type built by US students from George Mason University, Washington D.C. using a toy car as the basis. It trims the grass using an electrical bar cutter which requires less energy than a radial blade system which conserves power.
The ‘science bit’ is that it then collects all the trimmings as it goes and converts the grass into dried pellets that is can then turn into fuel to power itself along.
The secret is in its internal small biomass gasifier which is a furnace that is able to convert organic matter into fuel and in this case – gas.
The mower is autonomous thanks to its in-built proximity sensors which will stop it bumping into things around the garden or people. It is also able to self-navigate and follow a course setout using its onboard GPS tracking unit.
