#2524: DryMow

You can get pretty much any organic powder to explode, if it’s fine, dry and concentrated enough.

Today’s invention takes advantage of this to create a self-fueled, cordless lawnmower.

On a dry day, the user would start cutting grass in the old fashioned, push-mower style. There would be multiple, close blades on a single horizontal shaft, so that any grass would be very finely chopped.

This would create a cloud of dry particles which, when introduced into the combustion chamber of the mower engine, would act as fuel.

A conventional spark plug would ignite the powder/air mix. This engine would drive the many blades so that the lawn would all be converted into fuel for the mower.

There would therefore be no need to transport cuttings to a bin.
