Would Hydrogen on Demand (HOD) technology have a weight problem if used in aircraft?
If you look at the atomic weights of Hydrogen and Oxygen gases you see for every 18 lbs of water, you only have 2 lbs of hydrogen. A Learjet 40XR can carry 5375 lbs of fuel. If that fuel was water, that’s only 597 lbs of actual hydrogen fuel. The remaining 4778 lbs is oxygen. Perhaps it could be handy to have for extra altitude, but doesn’t help much with distance. So this earlier research study that gives a thumbs up for hydrogen propulsion in standard aircraft turbine engines would necessitate only carrying pure hydrogen to work. Recycling the exhaust might be somewhat feasible for internal combustion engines, but is absolutely impossible with external combustion engines. Another way to illustrate the weight issue: if you have 2 gallons and one quart of water, 18 lbs., the quart is the hydrogen’s weight and the 2 gallon jugs are the oxygen. Did you ever realize the air you breath was so heavy? 12/20/2006 Donald Trump Gives Miss USA (party girl) a 2nd Chance. Hmm I wonder if her looks
