Detroit Q. Spider posted:Man I really hope this gooses hydrogen development as a fuel. The most abundant element in the universe and the only waste product is water vapor? Yes please. From what I understand, the methods of producing hydrogen currently aren't sustainable. This means it currently requires more than a BTU to make a BTU's worth of hydrogen and bring it to market. This includes generating it, compressing it, and transporting it. There is a similar issue with corn based ethanol. But the United States likes corn so much they do it anyway.

There's a wheeled jack under the car that lifts the wheel off the ground; let them set world records for non-stop endurance driving from California to NYC and back to California without ever stopping, and then later Alaska to Mexico City, without stopping. One guy would shimmy out on a retractable running board, while another climbs on the hood and sets up the plywood platform on the wheel that needs changing. The guy on the hood then climbs down to the plywood and changes the tire just like you normally would, only the car is still moving at 25mph. They refueled in a similar fashion. Safety was apparently not much of a concern. https://www.youtube.com/watch?v=yT8azxnVAC4&t=390s

That is pretty badass. You could do it nowadays without ever changing the tire, though. I guess that takes out some of the heroism.  I would've put two platforms, one on each side, with a sliding rail the length of the car like on an early Caravan. Then you don't need hood guy if you have a tire guy on each side of the car and a rope connected to the platforms.

I agree there, the real argument against hydrogen as stated earlier is that you simply can't get it without consuming another fuel/electricity. So why not just bypass the inefficiency and consume the other fuel/electricity directly? Especially considering that we already have a huge electricity infrastructure in place. It's a great fuel, but until we're producing it with nuclear power plants or some bioproduction, it'll never be economical or efficient to use.

The hydrogen isn't being burnt. Power density of liquid vs gaseous fuel is irrelevant, the hydrogen is being used in a chemical reaction with air to produce electricity. And maybe you missed the point about it powering an endurance racing prototype? Sure, they won't be competing with the Audi hybrids in the "who can spend the most money" game (and don't get me wrong, the Audis are next-level type badassetry that sound amazing and are stupidly fast), but the whole point of prototype racing, especially LeMans, is it's where people get to try new things in the most punishing environment just to see if they work.  which was doing well until

The cheapest way to get hydrogen right now is from natural gas. Instead of going to hydrogen you could just go to natural gas directly and burn it in current ICEs with no modifications. The US has enough natural gas for 200 years, so why isn't everyone driving around in Honda Civic DXGs and gas Ram trucks? Same reason why they aren't doing it with hydrogen. Carrying a giant tank of volatile COMPRESSED GAS is a much diferent affair than a tank of volatile liquid.

Linedance posted:The hydrogen isn't being burnt. What do you think burning is? You still have to deal with the waste of converting some other form of energy to hydrogen before you can feed it to the cells; there are other gaseous fuels that can be dug straight from the ground, but are still not practical because of energy density problems, at least with combustion engines. Fuel cells have other problems too, ranging from some requiring more platinum than your catalytic converter, to just low power density. Hydrogen fuel cells will simply never be mainstream.

No it's not. http://en.wikipedia.org/wiki/Autogas We don't have LPG cars exploding all over the place. Ours hasn't killed me. not even once! CNG is a slightly different affair having a lower energy density still, but the systems are designed with safeguards and the tanks are pretty much bulletproof. It's not my fault that the majority of the U.S. is scared of LPG, CNG, Diesel and Metric.

No it's not. http://en.wikipedia.org/wiki/Autogas The most common car in the US(Honda Civic) and lots of trucks can be bought from the factory equipped for natural gas in the US. Most US households have ready access to gas lines. No one buys them because the cost of engineering the car so that it remains somewhat safe in a crash almost doubles the car's price. Also the tank takes up all the truck space.

dissss posted:How many service stations still carry LPG in Australia? In NZ its virtually gone now, because having the tanks and training staff up is just more money than its worth. The vast majority of them. It's pretty rare to see them not carry it. Although at the current time it's not the most popular fuel because even premium works out cheaper in $/km. They blame the LPG price hikes on international bs, but as far as I know LPG is locally sourced. Throatwarbler, it's pretty much been a perfected technology for a while now. I can't really comment on CNG but LPG costs ~$1-2000 to be retrofit for a mixer ring setup and ??? for liquid / gas injection. If I go back in time before the last year or so, if I were to get gas fitted it would have paid for itself in a few months. You can lose space, yes. It depends on where the tank is mounted and whether the vehicle is a total conversion or dual fuel. Total conversion a tank can be mounted where the original fuel tank was. Depending on the vehicle design sometimes the tank can go between the frame rails, under a tray or whatever. There are also smaller tanks which can be fitted instead of a spare tyre. As said the tanks are strong, plus there is a dual solenoid setup, tachometric relay and I don't know what else. If the vehicle is demolished to the point an LPG tank is ruptured odds are the occupants are dead anyway.

Of course the tanks in these are probably stronger than the cars because Chinese car, so uh, you know. The natural gas Civic costs $27k in the US, vs $24k for the Civic hybrid. According to Honda that's the price because that's what it costs to build, probably more because I think they get some kind of government subsidy too.

Carrying a giant tank of volatile COMPRESSED GAS is a much diferent affair than a tank of volatile liquid. Right, hydrogen has its issues, but at least its mostly renewable. Manufacture of hydrogen with next gen nuclear plants is above 50% efficiency. They use waist heat from the reactor to speed the reaction involved in braking down hydrogen from water. Our supplies of nuclear fuels are magnitudes higher than CNG. My schools has several fuel cell power projects going on. There are issues to over come, but the vast amount of research going into it tell me that It wont be that much longer until its viable. Most people would have said solar power was pointless years ago because of the efficiency of the panels but these days they are pretty good. Technology moves fast.
