The world needs a new source of energy, an unspillable source.

Engine that burns powdered solids?

Is there a commerical mfg who builds engines which can burn solid fuels, powderized, such as coal, biomass or such fuel? Without having to burn it in a boiler to make steam to power a turbine to run a generator? Not just little 5hp or 10hp engines but bigger ones from say 200hp up to 5000hp.
