Im STILL waiting for a sensible answer!
PLEASE – will somebody answer (sensibly):

Where does the Hydrogen (AND OXYGEN to recombine it, with don’t forget)come from?

IF there is an efficient / low emission way of producing large amounts of hydrogen – then im all for it!

Look – the idea of a “fuel cell” that recombines hydrogen and oxgyen to produce electricity, with water as the only by product – is NOTHING new!! its been around since the 19th Century (google it!!)

We’ve all done (years and years ago) the famous experiment of putting electrodes into water and watching the bubbles of oxygen and hydrogen appear – and then excitedly talked about the reverse process – the “fuel cell” that recombines the oxygen and hyrogen to creat water again – and of course electricity.

and the idea of bolting one (fuel cell) into a lightweight box with a seat and steering wheel inside – and 4 wheels outside is nothing new either!!

Oh – and when the article says:

and will run at the equivalent of 300 miles per gallon. It will have a range on one tank of hydrogen of at least 200 miles.
what does that mean?

does that mean the equivalent of 300 miles per gallon of petrol/diesel –

or does it mean 200 miles on one tank of hydrogen (in liquid form?)
ie a tank of about 2/3 gallon of liquid hydrogen?

Oh – and in winter – you wont have any power to run a heater!!!! (cos you use some of the waste heat from the good old inefficent fossile fuel engine for that in your car!) –

as ….we arent seriously suggesting that we use the fuel cell for extra electricity (in addition to that used for motive power)
to run a heater are we???? – god forbid!!

You’ll need thick clothes to drive this in winter!!

Hi Nelli, (sub post #1)

You suggest googling “electrolysing water?”

But – if you electrolyse water – you’re using electrical energy to do it ! ..

and Nelli, where does the electricity come from to do this??

mainly from fossil fuels !! – and not very efficiently either !!

so all weve done is moved the use of fossil fuels from powering the car directly …. to generating the electricity to electolyse the water, to produce hydrogen, to power the car!!

reminds me of an old song…

I knew an old lady that swallowed a fly….

STILL no answer to where the Hydrogen comes from??

Aren’t Riversimple reading this??

Gone very quiet !!

Hydrogen, how does it work ?

Hi Wayne

Im not against the car – and the way it works
In fact I’m all for it (dont like the styling at all though – i think its really ugly !!)

All im asking for is a SENSIBLE discussion on where the fuel (hydrogen AND oxygen dont forget!!) comes from !!.

We’ve had all this many times before about hydrogen fuelled cars – and NO-ONE EVER mentions where the hydrogen comes from – and
YES – what about distribution -of Hydrogen in LIQUID form!!! ????

And -how about fuelling the car? injecting liquid hydrogen at high pressure?

Yes- I agree that technology has moved on – I should know – as a Chartered Electronic/Electrical engineer of over 40 years standing – Ive seen and worked with many of the changes!!

I am in fact extremely interested in methods of providing cheap / green energy. I’ve been discussing this topic for decades,long before it became “fashionable”.

We were experimenting with more efficient ways of combustion in cars in the early ’70′s when the international scene at the time forced up oil prices (petrol went from about 33p a gallon (yes GALLON) to about 50 -55p almost overnight)

Problem is though – even though I’m an engineer, I really dont think “high tech solutions like this are the REAL answer.

What about Photosythesis (been going on more millions of years in plants producing Carbon and oxygen from sunlight

and what about sunlight itself? – look at how much enrgy from the sun falls on the earth every day – FAR more than we need !!

If only we could harness these two alone -which are non polluting and essentially “low tech” – we would surely be finding a REAL way out of the problem !!
