Another thing to note is the difficulty in reaching a better MPG.
Whilst some hybrids claim 60MPG, to raise that figure to 100 would require an extremely clever design, or many compromises.

In reality this may mean that the car may take 30 seconds to reach 60 miles/hour and go through 10 gears getting there. Not exactly ideal..

what about the rapidly expanding and contracting metals in the engine wouldnt this greatly compromise reliability and durability ?

You know, I thought of an easier way of using steam to improve the efficiency of IC engines, which could be (relatively) easily applied to existing equipment.
How about running all the ancillaries (alternator, water pump, air conditioning etc.) from a steam engine which simply uses lost heat from the exhaust?
By having a flash boiler set up in this way there are no moving parts like a turbo in the hot gas stream. A flash boiler coil could simply be wrapped around existing pipework.

Rehashed old idea that the original patents have expired on.
These things were bandied about 50 years ago, and no one could make em practical because of lubrication, corosion and volume problems.
Yes, it will work, .. for a while.
With all the computer control, advanced materials and lurication tech. we have today, why does his engine look no diferent than the ones they tryied back in the thirties?
I’ve been following Mr. Crowlers work on this for a while, and I have thus far seen no evedence that he has solved any of the problems inherent in these engines.
How about an award for developing misleading hype for investors?

This is a fantastic idea. I have long thought gasoline/diesel-steam hybrids to be a great idea. But one problem that I see is the rapid expansion and contraction of the surfaces that come into contact with the injected water. I think it will reduce engine life damage the cylinder walls and piston. I wish the best of luck to Mr. Crower, and I hope to see this engine in mass use someday, but it seems that he will have a number of obstacles to overcome.
