Let’s compare RP-1, hydrogen, methane, solid rocket fuel and even hydrazine-based hypergolic fuels. Going over these will pretty much cover the vast majority of rockets and what fuels they use. Let’s start off with the dirtiest of rocket propulsion, and that is solid rocket boosters. You...
Thin pieces of fuel burn more quickly than larger pieces because a larger proportion of their mass is exposed to oxygen at any moment. For example, you could burn up a pile of wood splinters or paper much more quickly than you could a block of wood with the same mass, because splinters...

The primary concern of engineers is how to get a spacecraft to Mars, on the least amount of fuel. Robots don’t really care about the hostile environment of space, so it makes sense to decrease the launch costs of the rocket as much as possible. ...
(150,000 kilometers per second), the starship would need to burn 81 times its mass in hydrogen, the fuel used for nuclear fusion. The technical manual for "Star Trek: The Next Generation" lists the Enterprise as more than 4 million metric tons in weight, so the ship would need more ...
Consider how much coffee you drink if you're looking for a Rocket Espresso machine. Are you an occasional sipper or a multiple-cups-a-day person? This will help you pick a machine with the suitable capacity and features. Also, check the space in your kitchen or coffee nook. Rocket Espres...
Spacecraft use a more primitive design called an alkaline fuel cell (AFC), while much greater amounts of power could be generated by an alternative design known as a solid-oxide fuel cell (SOFC). Microbial fuel cells have an extra feature: they use a tank of bacteria to digest sugar, ...
