High-energy-density matter

High-energy-density matter (HEDM) is a class of energetic materials, particularly fuel, with a high ratio of potential chemical energy output to density, usually termed "thrust-to-weight ratio", hence "high energy density". The substances are extremely reactive, therefore potentially dangerous, and some consider them impractical. Researchers ...
