UK's Loughborough Uni Demos Hydrogen Motorcycle

rolandw writes "The Beeb have a piece about Loughborough University's hydrogen motorcycle and one of the UK's first hydrogen fuel pumps (presumably all developed by their excellent Aeronautical and Automotive Engineering department). Offering 50mph, the ENV will have a range of 100 miles on a 3-minute refill of hydrogen. By-products are warm air and 'drinkable' water. It will be interesting to compare these hydrogen powered vehicles with the hydrogen fuel cell-powered vehicles as pioneered by such as the Morgan prototype 'Lifecar' in the near future."

And yes, with a catalyst, the amount of raw energy input changes in efficiency with the use as well as you have to look at the secondary process of using the stored energy. We aren't talking about hydrolysis, we are talking about hydrolysis as a means of storing energy and then reusing it later. Energy is moved far beyond just the chemical reaction which has different levels of efficiency currently.

      By ascribing magical powers to catalysts as you do, then indirectly that's indeed what you're doing. If it worked that way then you could reverse a reaction and be left with an energy profit (or deficit) even assuming 100% theoretical efficiency.

      I think your attempting to blind yourself by your own rhetoric. Why would we use a catalyst if we could cause the reaction without one? Because it is more efficient, that's why. In this context, we are talking about splitting water into it's basic elements. So why would a catalyst or a set of catalysts be used when simply inserting energy into a pool of water will cause the reaction? In case you don't know, it is because the catalyst allow the reaction to occur using less energy otherwise your simply making a Rube Goldberg machine with no benefit. I mean why would they waste the energy creating the catalyst or finding specific catalyst for specific reaction that can be done without them?

      The bottom line is that with those catalyst I mentioned, you can create as much hydrogen and oxygen from water using less energy to initiate the process and you can create more of each using the same amounts of energy. No energy is magically created, the processes become more efficient and you use less input energy.

    Vehicle not carrying extra protective carapace gets great fuel economy. Film at 11.

    If we all drove motorcycles, we would be able to power them off gasoline, because they regularly get two to three times as many miles per gallon as cars. Except that they're wildly dangerous, because they offer no protection in a crash, especially when everybody else is driving cars.

    We see the same story in cars all the time: they build a car that's little more than a motorcycle, and by taking away all of the protective (and heavy) metal, it gets huge MPG. Even if there is some sort of useful advance in the engine technology it's dwarfed by just getting rid of all the metal.

    So you can build a hydrogen motorcycle. So what? We knew it could be done. All you've done is to offer us a motorcycle that's very safe because you can't refuel it anywhere so you can't actually get it out of the driveway.

      I'm glad you said 100 years and didn't repeat one of those robot feel good statements like within the next 15 years or something.

      I ran some numbers relative to my experiences a while back and it is alarming at how long it would take just to replace passenger cars with something cleaner and not fossil fuel powered. I don't have my numbers and sources at hand, but It appears that in good economic times, about 6% of the passenger vehicles are replaced per year. This means if we had something today, it would take something along the lines of 16 years for an effective replacement. But we still have some problems with those numbers because the replacement rates do not account for wrecked and destroyed cars or population growth. The reality is that cars generally get pushed down to poorer and poorer people when the more well off replace them. I have two cars over 20 years old right now and I know people who are working on 25 or more year old for everyday drivers. It doesn't look like either of us will be replacing them anytime soon with the economy the way it is. It will take a seriously long time to replace the vehicles when something comes along if we remain practical about it and don't confiscate people's rides.

      I'm guessing 25-30 years for 90% of the passenger car for all but collectors and such. And possibly longer if the replacement doesn't have as long of a usable life span (usable as in someone can use it not that it is efficient or cost effective to use it). And this clock won't start ticking until production is ramped up to a point that no new fossil powered vehicles are being produced any more. This could be another 50 or more years too. It makes your 100 years a lot closer to reality if we were to look at it realistically.

But the tank is the size of a large bike tank. You are in effect asking for a machine with about 4 times the hydrogen capacity, and this is a very big scale up indeed. How close do you want to be to a large tank full of compressed hydrogen?
