down, safety and infrastructure issues appear and still are four-time les hydrogen atoms in any liter of liquid hydrogen than in a liter of gasoline. So the key problem is to find a way to store hydrogen in a safe and dense way. No hydrogen flame has the ability to truly melt tungsten. There is much disinformation about hydrogen burning, mainly because the burning temperature of hydrogen flame is very unstable; therefore hard to measure and dependant on many factors, like volume and cleanliness of hydrogen and oxygen used in the reaction, temperature, pressure and any other chemical elements in touch with the reacting system. Almost any chemical element or compound can serve as a catalyst or inhibitor of the hydrogen oxidation reaction. Illusion of tungsten melting could be easily created with side reactions. Hydrogen improperly burned in air creates polluting nitrogen oxides. University of Stanford (May 2000, WWW) argues that although some nitrogen compounds may also be produced and may have to be controlled the main problem of global warming - carbon dioxide is not produced in any quantity. Hydrogen can rot metal through an embrittlement and will easy diffuse through most other materials. Hydrogen can form various compounds with almost all metals, except non-reactive metals like gold and platinum, and because hydrogen H2 molecules are very small they can diffuse through many materials, like most hydrocarbon-based materials (plastic, rubber). Consequently it means that special materials and their combinations need to be used. Water is not a fuel. It is an ash. Often, water is mistaken to be the source of power but water is only the product of the hydrogen and oxygen reaction, not the actual fuel. Normally, a monoatomic gas only briefly exists in tiny amounts. There is a lot of free hydrogen on our sun and on other moons and planets, but on Earth only a few very rare gas wells release some free hydrogen, but only in very small amounts a...
