    1. Hypothetics: let's say it takes 1/100 of the current fuel to take a spacecraft out of Earth's atmosphere. What happens?

      This is obviously a thought-experiment, but maybe an interesting one. Let's say we get a super-efficient, eco-friendly alternative fuel that can do whatever rocket fuel does now with 1/100 of the...

      This is obviously a thought-experiment, but maybe an interesting one. Let's say we get a super-efficient, eco-friendly alternative fuel that can do whatever rocket fuel does now with 1/100 of the cost, 1/100 of volume and 100% more efficiency. What does it change in the short term?
