Never mind acetone and additives! Which of these incredibly fantastic two fuel saving devices would you put your money on?

Even if any of these wonderful inventions actually worked, a certain Gordon Brown would just put up the price of fuel to compensate....

Hydrogen gas in close proximity to heat and sparks?

Anyone remember what happened to the R101 ...

I notice the second article mentions 'Worldwide Patents'. Any decent inventor who has an ounce of IP law knowledge will know that such a thing does not exist. Even the World's multi billion pound turnover multinationals do not have 'Worldwide Patents' because they are not needed.

The first one...

OK, so this thing uses electricity to generate hydrogen from water by electrolysis. It then takes the hydrogen and oxygen created and burns it in an IC engine. The alternator generates electricity which is used to generate hydrogen from water...

see what I'm getting at?

Eureka! Perpetual motion by Gad!
Throw the baby out with the tap water? - Number_Cruncher
Well, that's the first item dismissed - and rightly so IMO.

The second one just looks like an expensive and inefficient supercharged two stroke to me. I think that the waffle about seperating the different parts of the four stroke cycle is something which is done far more elegantly in an ordinary two stroke, which pumps the inlet air using the underside of the piston, rather than having another piston and cylinder just for the purpose.

So, which would I put my money on - neither!, nor will I be caught pouring any nail polish remover into our car's tank!

Don't go there .. old backroom hands will recall the story of perpetual motion, pink chieftain tanks (or wa sit a centurions?) and Ladas. Not worth revisiting...

BUT back, screaming and kicking to topic.
BMW has for many years been pumping its hydrogen fuelled mega eco friendly motor car - all it produces is steam!
But they seem to have been ignorant of one fact .. steam IS a greenhouse gas!
Anyways, stuff the grandchildren, I like driving fast cars!

Shush Mike! The whole world is running on the belief that the hyrdrogen economy will save us all. Except of course Greenpeace et al have forgetten that the hydrogen to power our cars doesn't exist naturally so we have to burn fuel to make it. Oh and of course that hydrogen is massively inefficient as a method of transporting energy because of the volume of it needed. Don't you just love Colin Oram's modules for a cynical take on the real world?

Ah! but Chris that's where the electrolysis comes in. In the future we will be using excess energy created by wind turbines to produce hydrogen from water at night to power our cars in the day! Of course we'll all be under 5 metres of sea water by then :-P

That'll be useful. Seawater is a scientifically feasible source of uranium.

And just really rain on the parade of the German "inventer" of the two stroke engine with one compressing cylinder and power cylinder, my 1914 Motor Manual has it included as being largly superceeded by then!

In fact, a lot of the current mechanical ideas had all been tried by then. Generally either the cost of the component, the accuracy needed, or the materials technology of the time had ruled it out at that time. You make claims for first in this industry and likely as not someone will prove you wrong.

Hydrogen powered cars. Store the gas as a liquid at -260C (or around there). Leave it too long in the sun and all your fuel will evaporate..

The second principle which is basically a supercharged 2-stroke where one cylinder is a supercharger for its neighbour. It's not a new idea - didn't Trojan use it before the war and up to the 1950's.

The water powered car looks interesting - there have been urban myths about inventors coming up with water powered engines before and being paid off by the oil companies - perhaps those myths are true after all!

BMW are developing a Turbosteamer device - sounds like something you might see on Ebay but it's real. The exhaust heats water in a 'flash' boiler and this is used to drive a steam motor that feeds power back to the crankshaft. There is a condenser so that the steam power system is s closed loop - no trail of steam behind your Beemer! BMW claim a 15% power increase on the 1.8 litre 4 cylinder test engine.

I have wondered why a manufacturer has never progressed an idea like this, or any other external combustion/heat engines such as Stirling or Rankine, to make use of wasted exhaust heat.

I guess the main problem is that the extra power is not delivered instantaneously on start-up, and the space restriction under the bonnet. A 15% power increase may be accompanied by a 15% weight increase!
