He has developed several prototypes of hand-cleaning devices that can be mounted on walls, as well as a portable, battery-operated model the size of a large electric toothbrush.

This model train was mounted with a synthetic radioisotope (a source of neutrons - or energy) and sent on a continuous three-day loop on hobby train tracks to help inform other fusion experiments.

The second model is fitted with a more conventional single frame windscreen and is designed more for the serious off-roader with additional lighting mounted on the roof.
