View source for Engineering:High Energy Density Matter

'''High Energy Density Matter''' ('''HEDM''') is a class of energetic materials, particularly fuel, with a high ratio of potential [[Chemistry:Chemical energy|chemical energy]] output to density, usually termed "[[Engineering:Thrust-to-weight ratio|thrust-to-weight ratio]]", hence "high energy density".  The substances are extremely reactive, therefore potentially dangerous, and some consider them impractical.  Researchers are looking into High Energy Density Matter that can provide much more lift than the current [[Chemistry:Liquid hydrogen|liquid hydrogen]]-[[Physics:Liquid oxygen|liquid oxygen]] reactions used in today's [[Engineering:Spacecraft|spacecraft]].
