“Hydrogen has more than 4 times the energy content compared to petrol!”

yes, its more explosive but it has a lower density so you need more to cover the same distance. Then there’s the supply and demand issue, producing hydrogen is expensive. There are some interesting technologies on the way which may help but the time to market maybe too long.

This car is an excellent concept and drive claimed it has been in development for 30 years!!. But the reality is electric cars not Hydrogen. They will be available quicker and once people get use to the idea of plug in who’s going to want to visit a petrol station again.

I think an internal comustion engine that runs on hydrogen seems like the way to the future. As it seems as though it will provide all the fun things conventional cars provide us with now, only we don’t have to worry about oil, although by the time it becomes main stream the last barrel of oil ever produced will probably be on display in a museum some where.

There has been huge break throughs in hydrogen storage in only the last few months and there is development of bio-hydrogen (produced by microbes – like biodiesels) currently being developed. It is a viable alternative – and potentially the best.

Mainwaring in the ideal hydrogen economy hydrogen is provided as a byproduct of several industrial processes. So hydrogen is a very good idea. The question is more this: is enough hydrogen produced as a byproduct to power everyone in the hydrogen economy, or just a few.
Hydrogen is a perfectly viable alternative, but for how many people?

Realcars the Hydrogen 7 is internal combustion on Hydrogen and can switch to petrol at the push of a button. It has separate tanks for hydrogen and fuel and it’s owners will probably still use petrol most of the time because there are very few filling stations in the world that are compatible with the Hydrogen 7.

Whats wrong with you Captain Mainwaring?? Hydrogen has more than 4 times the energy content compared to petrol!

BMW PR spin at its best. Hydrogen is straw-clutching technology. Might be emission-free out the tailpipe, but takes more fossil fuel to manufacture than what it saves, is too temperature-sensitive to store and reticulate effectively, and only has half the energy of petrol. Not to mention the cost. We’ll all be dead before this is a practical transport fuel alternative.

They could assess there car against others, gain feedback on what others are doing, see how others perform – where is FORD. AWOL as run by USA for USA and minimal input with designs that is only now changing with kinetic hot look. Ford should hang there heads and give up as they are RS!

Whatever Realcars…..fact is hydrogen is in this tour and Ford at sea doing SFA R&D as still at round table working out how to release designs and compete! No wonder Toyota are number 1!

The tour is from the US cities of Portland, Maine to Santa Monica, California
