great idea. roblem is, like ll other great inventions over hte last 50 years (more than that is you count the true diesel engine) that would eliminate the need for oil, their patends are purchased by big oil companies and we will never see them. Look into what industry has given the most money to colleges and think tanks over the last 100 years. You got it, big oil. Kinda like the big bad wolf getting his scientists to work on building the better pig house.

As for the niose factor and holes in the helmet. It is wind noise that causes hearing loos for bikers, but engine noise. Not all bikes are that loud and most that are never see more than a couple hundred mile per year. The true riders have quiet bikes and cover hundreds (even 1000 or more) miles in a day. FWIW

Yet a Tomos Moped can be modded to do 50 MPH at 49 CC and still get 100 MPG. wokka wokka wooka.

Unfortunately it looks like yet more marketing hype. Here we are in mid 2007, and still no sign of any production models.

When I checked out the bike website the price has increased to 10K USD, and a lot of the technical numbers just dont add up, such as how you can get 100 mile range using a 6KW Motor (is that Max power, or continuous) and just 2.4KW of Hydrogen?

To put that into perspective 1 HP is about 750 Watts, so they have enough Hydrogen to deliver a constant 3 HP for 1 Hour, or 1 HP for 3 Hours.

To get a Human powered bicycle to maintain speeds of 20-30 mph requires something like 250-350 Watts, and thats with exceptional aerodynamics (Lance Armstrong on a carbon fiber TT bike).

I guess its possible that with great aerodynamics and exceptionally light weight they may be able to achieve 40-50 mph on around 600 Watts, and from that get to 100 miles in around 2 Hours?

Personally, I feel that adding noise would be rather silly.
One of the disadvantages of the motorcycle is that the engine noise and helmet effectively deafen the rider. With a silent engine, ear holes in the helmet become practical.

I’m seventy years old, since 1951 I,m found of engines ( Vespa ). I,ve designed a new I.C. engine able to improve mechanical efficiency of approx. 3 points and to reduce virtually to nil vibrations and lubricant consumption.
I think this is important in hydrogen I.C.E where the cost of combustible is very high. Are you intersted in my project ? My email is verganimapelli@alice.it
