Where is this miracle flashlight?
In my younger days, I thought that perhaps we would use solar power to split water for this type of thing, but I think it takes more energy to do the water splitting than hydrogen is produced. If the approach was to have a hydrogen cell that was slowly filled with hydrogen by some constant low-power source, that might work, but a tank with pure hydrogen of any quantity is a very dangerous bomb.
- yock 15y agoa tank with pure hydrogen of any quantity is a very dangerous bomb. That seems like a solvable problem to me. By limiting concentration, removing oxygen, and investing heavily into rupture-resistant tanks, is it feasible that the risk could be brought in line with other fuel storage standards?
- ryandvm 15y agoI actually have a vehicle that is powered exclusively by a very efficient hydrogen storage technique. It basically relies on a liquid that is made up of long chain hydrocarbons. This makes the fuel source both very energy dense and relatively stable.
- sharkbot 15y agoWow! The wonders of such a storage technique! Hopefully the production of this liquid doesn't peak anytime soon... :)
- qdog 15y agoAccording to Wikipedia, hydrogen is flammable in concentrations from 4% to 75%. Its likely any tank and transfer system for hydrogen fuel would be cost prohibitive or risky. It's been a long time since I had chemistry, so I don't know, a lot of people are interested in hydrogen fuel. However, the original post about the boat succeeding at this seems unlikely with current technology.
