Magnetic Device Separates Hydrogen from Oxygen

High temperatures have been used to dissociate water, but in many cases, the oxygen and hydrogen recombine when temperatures drop. A new device magnetically separates hydrogen from oxygen at elevated temperatures. Steam enters a reaction chamber, heats to over 150 °C in a focused solar beam, and...
