i come from a country with really poor power supply an a lagging government so if this could happen it could be an additional power source for a small or fixed community to add to there daily power input , adding to that from the national grid and eventually work in other places round the world in third world striving countries as well. it more than likely wont have an over use of the dirt since its totally collected from the community daily use. to reduce the environmental effects has also been thought about can use the chemicals used in modern dirt to energy plants. just small pellets, spray it once the allocated time for the dirt to be burnt elapses in the heat to steam collection chamber before the bin bot rolls out. it really could cost quite an amount and getting anyone to believe in you nowadays is tougher but if i can accomplish the binbot aspect atleast and show a working prototype am sure i could get someone interested. here or overseas.
