The first blog was titled What Will be Powering Our Cars in the Future? and the second was called Alternative Forms of Energy : Part II in which I was a co-author with allpar member jstwe314.

The speed at which Hydrogen ignites is much faster than normal fuels, like petrol and ethanol. You might have notices higher 'Octane' (R.O.N) fuels are "better", as they burn slower, and allow a more efficient combustion as the travel of the engine crank. Hydrogen releases a very quick burst energy and is therefore inefficient. This is also detrimental to the engine components and will cause sever engine ware and damage. To run Hydrogen you need comparatively retarded ignition timing and low compression (or at lease low static compression). On a 8.2:1 engine at 0 degrees timing at 800rpm, advancing to 5 degrees to 4000rpm, an engine will run on Hydrogen, although it denotes, and I estimate the engine would last 10k-20k km’s. 9.7:1 compression engine and a variety of timing's, the rings give way and the engine seizes. Those are the 2 most successful of my tests. The use of Hydrogen to power cars requires another 100yrs of engine development. Or, if given the funds from US defence, 1 week.
