A new study by a team at the National Renewable Energy Laboratory (NREL) concludes that a high-pressure, scalable, intra-city hydrogen pipeline system could improve the economics and logistics of hydrogen delivery, making it potentially cost-competitive with gasoline. The smallest modeled system connects eight existing stations.

Since the IC was invented, all of the metal that connects transistors was formed above the silicon surface. The Practical Power of Fusing Photons Chad Hagen Silicon solar cells are relatively cheap and plentiful, but they miss out on a lot of energy in sunlight. Too bad rhenium is one of the rarest elements on Earth.
