This lawn maintenance device would be powered by grass clippings gasified in its fuel hopper. The airflow thru the bag would dry the "fuel" sufficiently for it to burn. Then it would be smoldered like a giant cigar in the end of the hopper to fuel a gasifier to power the engine. Large ones would be self
propelled ditch mowers for cutting the side of the highway. They would gasify grass, sticks, trash, and anything in their path. Metal left in the hopper post compustion could be recycled normally. Maybe if fuel was left after cutting it could be used for power generation...
Grass-powered mower.

I think there's an energy balance error here: unless the grass being clipped is already dry, the latent heat of evaporation of the moisture in the grass will be greater than the energy available from burning the grass. |
