In today's podcast, we're going to look at research into how boron can be used as rocket fuel. Boron has a high intrinsic energy density. It's inexpensive, plentiful, and stable, making it a good choice for solid rocket fuels and an additive for jet fuels to increase energy output.
However, the oxide shell and its impurities make boron unreliable at the ignition point. Research is ongoing into overcoming these impurities so that boron fuel may be used more widely in space travel.
