The Hybrid Scooter

anthemaniac writes "Hybrid cars are all the rage. Now comes a hybrid scooter. It gets beyond ethanol and lots of batteries, though, running on a hydrogen fuel cell that charges a battery. During braking, energy is also harnessed. All this and speedy too, says inventor Crijn Bouman of Delft University of Technology in the Netherlands. For now, however, the prototype lacks one crucial component: the hydrogen fuel cell! It's coming, Bouman says. Yes, just like $5/gal gas..."

best guess of a drowsy mind.

The Hydrogen Fuel-Cell is able to both charge and provide power to the engine. The electronics are jacked if it doesnt work this way. My guess is that the H-power would go straight to the motor in a high drain situation, and in a lower drain the H power would work to keep the Li battery at a modest reserve. The regenerative braking couldnt recharge a fuel-cell, but would be great for the Li-battery.

My best guess is that the Li battery shouldnt need to be all that big (capacity wise), if your running a fuel cell then you already have a very efficient way of making electricity on demand, so there is less need to store the energy in the Li batteries. It could allow for quick bursts of speed, and a reasonable choice for regenerative braking.

Re:SUV-bike collision?

What happens when a vehicle with a drunk driver collides with your vehicle? SUV vs. car: people in car survive if they are properly restrained. SUV vs. bike, even with proper helmets: Don't even go there.

You can disagree with the site, but the sources are another matter entirely. It's something to think about next time you see a jacked-up SUV with a super reenforced "brush guard" steel bar running across the front grille blowing through another STOP sign.

While SUVs pose serious safety problems for their occupants, recent studies are showing that SUVs are greatly increasing the danger on our roads for drivers and passengers in other cars. Federal information shows that although light trucks account for one-third of all registered vehicles, traffic crashes between a light truck and any other vehicle now account for the majority of fatalities in vehicle-to-vehicle collisions. Of the 5,259 fatalities caused when light trucks struck cars in 1996, 81 percent of the fatally injured were occupants of the car.(9) In multiple-vehicle crashes, the occupants of the car are four times more likely to be killed than the occupants of the SUV.(10) In a side-impact collision with an SUV, car occupants are 27 times more likely to die.(11),

Re:nobody's going to stop buying SUVs

I'm reasonably certain that you'd be safer in most of the offerings from a certain swedish brand of cars recently bought by Ford than you'd ever be in an Escalade.

SUVs don't make you safe, it only makes you bigger and gives you more kinetic energy to get rid of. Sure, it'll trump a 1980s Ford Escort, but that's not because an SUV is safe, it's because the Escort is shitty. http://www.euroncap.com/ runs a good testing program and you might note that a Toyota Prius gets a better safety rating than a Jeep Grand Cherokee.

"because when it comes right down to it, they're safer. Sadly, the reason they're safer is they destroy anyone or anything not in an equivalent vehicle."

Actually there have been a lot of studies that have shown the opposite, for example have a look at the chart on page three of this pdf. You'll see that in this study the amount of deaths of the primary driver per million sold is higher in SUV's than large cars, midsize cars, minivans and imported luxury cars. Compact & subcompact are worse for the primary driver - obviously tin cans with a motor don't handle accidents well! Pickup trucks are the second worst and I'm suprised they're not more similar to SUV's. The worst is sports cars, possibly a combination of the historically bad handling of american sports cars and the fact that 150-200mph on a suburban road is usualy a bad idea!

$5/gal gas

[nmg196]

$5/gal gas? Wow that's cheap!

Here in the UK, it's already the equivalent of $7 per US gallon (97p/litre) or more. You guys don't know how good you've got it.

Mind you, the average "yank tank" probably uses more than double the fuel of the average European car. I think our average engine size is still under 1.6 litres in the UK.

Re:Not even funny anymore

Australians are in a similar situation - fuel here is the equivalent of USD3.90/gal.
It's a 9 hour drive to the next largest population centre of 200,000 people. Forget rail/bus/air transport.

The most popular large sedans in Australia have 6 cylinder engines that get about 27-30mpg highway. V8's are becoming, well, not 'rare', but they're a lot less visible than they used to be. While there's plenty of large cars and 4WDs, but theres none so large as what I've seen in the states as 'common'. For example, there's one (1) F350 truck in my town of 25,000 people.

You're going to have to adapt. Your cars will shrink, they'll become more fuel-efficient and their total horsepower will reduce. But saying that, you'll still be driving them everywhere for a long time yet.
