Hydrogen would start making sense if we had local production using artificial leaves. Use solar energy to electrolyze water, use the hydrogen in fuel cells. 5l of water would provide enough H2 to run your house for the day, another 3l for the car, according to Dan Nocera at MIT.

Throatwarbler posted: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. I'm mostly staying out of this because I don't care. But this statement is like saying that most houses have electricity and water so they can easily create a hydrogen supply for a vehicle. You need to understand that natural gas coming into your house at 20 PSI pre-regulator is a really expensive amount of equipment away from packing it back into portable tanks to use in your car.

Yeah, but doing this will burn more electricity than using the electricity to power your house. It takes more KWH of solar power to generate hydrogen to run your house for the day than just running your house for the day on straight solar power. And until someone invents an over-unity power source (i.e. never) it will always be so.

Sadi posted: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. Solar power sucks everywhere because there's simply not much power density in solar. Hydrogen is a pretty lovely storage medium. You have to use up some other energy just to manufacture it, it is hard to contain inside typical gas tanks, slips past seals with amazing ease, and makes most tanks brittle. It is a nastier beast than any other fuel on the table. Using excess solar or nuclear to make hydrocarbon fuel will take precedence over hydrogen, not just because it will retrofit to existing vehicles easier, but because it is safer and more dense.

Linedance posted:sure, the closer you get to work, the longer it takes, but goddamn do you get home quick! Personally I can't wait for friction powered cars, but the hard part is convincing my coworkers to slide my car across the parking lot fast enough to build up enough potential energy to get home. Besides, they'll just end up putting a quarter on my rear bumper so I pull wheelies.

We have an electric car discussion thread somewhere, most of this has been covered in a slightly more grown up manner  If I remember the kit to turn house gas into cng is a couple of thousand dollars? I wish you could get it in the UK.

IF as a civilisation we loving man up and tell a bunch of ignorant religious assholes called Greenpeace and their ilk to go gently caress themselves then start beating sense into NIMBY's, we would be building nuclear power. Oh sure, a few tons of waste, but compared to the literal billions of tons of poo poo thrown into the atmosphere like we do now? And then, hey..... we suddenly dont have electricity problems. Crack all the water you want for hydrogen or gently caress, plug every car into the grid, there's more uranium in seawater than we could possibly concieve of using, let alone known reserves - which is far more extensive than you might realise. And not even starting on Thorium. But noooooooooo....... the greens have made this a religious jihad and that's what it truly is, a religion. THe hypocracy of beating everyone with science over climate change (Which, believe me I more than accept is true, deniers are morons) and then blocking their ears and LA LA LA at ANY science about nuclear and it's very real benefits, while throwing up any manner of bullshit. What a stupid species we are, the answer is availible right now and we let a bunch of retards ruin it.

We're lucky we have cars or electricity at all. For every kind of energy source there is, you have a vocal group of people against it with a laundry list of reasons as to why it's terrible. If that sort of opposition had been around 100-120 years ago, we'd be in the local bar chatting about our velocipedes instead now.

And how the hell do they balance with people climbing and moving all over the car? It also amazes me that the suspension and axles and tires just hold the entire weight of the car on the tips of two wheels for so long.

I've won a soda or two betting new guys at the warehouse that I couldn't do it. The bottle is a new angle but I think I could do that easily. To be fair I drive a 5 ton forklift and not a yard monster like that one.

grover posted:It's pretty obviously rigged. They've got a 3rd wheel where we can't see it. They also would have had to have modified the differential and/or brakes, too. At about 40 seconds in, the camera pulls behind the truck going sideways and gently caress if I don't see but two wheels on the ground. It wouldn't be too hard for the driver to be able to feel whether the truck's starting to tip one way or the other and adjust the wheel accordingly, just like if you're riding a bike too slowly for the spinning wheels to be enough to keep you upright.

You might be thinking of a LSD, which is between a locking diff and an open one. Depending on the behavior of the LSD, the off the ground wheel might not spin at all, but the one on the ground would still be driven. Also, I got your PM, but your box seems full. PM me your email address or clean out your PM box so that I can send you the answers.

A locking diff can keep both wheels turning the same speed and transfer all the power to the wheel on the ground though.

He then picked up his car with a grappling hook from his helicopter and flew away.  Dude has been a helicopter mechanic for the DC police for the last 20 years. I had no idea this was the case when I agreed to meet him. When we were working out the exact location he's like 'call me when you're close to the hanger and i'll come open the gate.' "right-o!" <hang-up> "wait - hanger? what?!"
