The men who governed Earth were far more intelligent than George the Third; nevertheless, they were beginning to show the same reactions as that unfortunate monarch.

He nearly brought down an airplane. Since the energy in chocolate chip cookies exceeds that in an equal weight of TNT, each gram of chocolate chip cookies will ultimately do more destruction than would each gram of TNT. Other researchers, however, dispute this conclusion; they argue that natural resources generate easily taxable rents that more often than not result in increased spending on education.

Some values may not be precise because of isomers or other irregularities. Today, producing hydrogen is cheaper and cleaner than ever before, and fuel cells are poised for a comeback.

Hydrogen fuel cells were once considered the future of green energy—until research on them was squeezed out of the U.S. budget. Download it here (version 2); Note that this table only contains engines for which I have data for the engine's thrust.
