Gas/Hybrid, Diesel, Diesel/Hybrid, Fuel Cell - where will it end?....
How about some external combustion in hybrid configuration.
I start a thread about steam engine for cars:

I will recommended to callously examine the steam engine...
dickon17 pointed out that the turn over of new cars is only 5% a year.
We need to think how to build the retrofitting industry that will speed up the turn over. We can't wait 20 years. Once particular solution is find it should be introduced as fast as possible.
I just wait when the hub motors...

Look like you mess a lot...not miss a lot :)
If you have in mind the bracket of water that been call in past a boiler that you pressurized to 500+psi that may be consider weapon of mas destruction. Modern steam boiler is a single small diameter steam pipe, so in the event of...

Excellent points. The fuel flexibility was the key advantage when steam power machines were used. It become even more important right now
Ability to used any thing that can be combusted specially renewal fuels and “green” fuels (dry plants, grasses so on) should be attractive...
NickE, I see that your idea about steam cars is closer to steam locomotive than contemporary power plant.
I will recommended to read the articles in the links that I provided, there some detail information of that 1920's design and new design.
1. You do not need catalytic converter if the...
GregLocock you are right, some type of engines are better in one function then others, so when choose, the deficiency have to be overcome or minimize.
Look on web page of Robert Bourque and his development:

That a piston steam engine have pretty...
GregLocock -"So what advantage do you think they possess over the current solutions?"
Extremely clean exhaust as compare to Otto and Diesel due to low pressure combustion.
1. no catalytic converter necessary
2. no muffler
3. no transmission
4. no starter (to that may be exaction, it have...
BMW use steam turbine as a secondary mean of power.
The system add only 13Hp.
80 years ego the 5000 lb steam cars with 20-30Hp could accelerate to 60 mph in 10s. That shocking eve today. The enormous toque (1000lbft) from 0 rpm was the key. Only electric motors can compare to that.
I kinda puzzle. I read article about Lysholm screw-type expander have 94% efficiency.
What that efficiency represent?
Let say Carnot efficiency will be calculates at 56%, does this mean that the Lysholm expander can deliver up to 94% of the calculated Carnot efficiency? So it mean that such...
I just read two article about steam car developments in pass and in there both authors getting to very similar conclusion: steam car can be good option for future car if today advance technology can be used. I believe at list one author read the other paper. However, the case is pretty strong...
I wonder is the multiple expansion that is used in steam engine to improve efficiency can be apply to internal combustion engine.
I thought that the first cylinder will work exactly in the same way as it work in Otto or Diesel, the exhaust will go to second cylinder to do second expansion. The...
Last two weeks was very fascinating. I read about some old developments of steam engine for cars. It it is very interesting what was develop on the first part of 20 century. The Doble brothers (specially Abner Doble) did amazing job on steam power car that even today, after 80 years, did not...
Probably power meter is more precise then spectrum analyzer The precision of most power meters are down to 0.03dB+/-, spectrum analyzer can have up to 2dB tolerance - depend of model and manufacture. Power meters from any manufacture should be OK (Boonton, Anritsu, Agilent, Rochde&Shawarz...)...
I just wonna start new thread, and fortunately I spot this one. It exactly cover what I have in mind.
I think most people have little understanding when exactly adding extra hydrogen to in regular fuel mixture (gasoline or diesel) will have any impact on general fuel economy.
The only time...
