Green power project - little hydrogen cruiser

AI Thread Summary
The discussion centers on enhancing an electric scooter's performance, specifically aiming for speeds of 40-45 mph using hydrogen fuel cells instead of traditional batteries. The user currently experiences limitations with their electric scooter, which has a low range of about 10 miles due to stock SLA batteries. They seek advice on how long a liter tank of hydrogen would last with a 2000W motor and how many fuel cells would fit in the scooter's battery compartment. Suggestions include considering a muffler for the existing gas scooter instead of pursuing complex hydrogen solutions. The conversation highlights the challenges and potential safety concerns of using high-pressure hydrogen tanks.

I bought this stand up scooter for $850. It's made by a company called http://goped.com" . It can go upto 20mph and I weigh 142lbs. But the problem is, as with all electric scooters is they get low range. Mine get's about 10 miles and it runs on stock SLA batteries packs.

I would like to go 40-45mph with plenty of torque. I already have a gas one that can do this but is too loud so I stopped riding is for my neighbors sake o:)

I would like to use Hydrogen fuel cells but how long would a liter tank of hydrogen last with a 2000W motor (my current one is 1100watts)?

How many fuel cells would I need? I wan't as much range as possible while still fitting the fuel cells in the 24"x12"x2" battery compartment.

Also can anybody suggest a motor?

Batteries are not perfect and a battery's energy storage is almost always proportional to its size. Don't expect a battery to output more power for a longer distance and take up the same space.

Well I said fuel cell should fit in the battery compartment but hydrogen tank may be about a liter and can be mounted separately somewhere.

Sorry about the confusion.Mybe I can get a high pressure tank for it and stuff it at about 5,000psi but would it be safe

No one's going to help me? :frown:
 
I can't help you because I know next to nothing about it. It does seem to me, though, that it might not be worth the effort and expense.
Can't you just put a muffler on your gas machine and save the electric one for a grocery-getter or inner-city travel?
 
Try contacting a supplier of fuel cells. They will know the details you are after.
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
