Smile New steam engine

Anyone for a steam engine to run a generator. Or how about a fresnal lens on top of a car to make steam. Check it out here:

Pretty neat idea, may have its uses in something. However, I would be a bit weary in trying it in an airplane.

Worth checking out the link as it is interesting.

Well, they were saying in "model airplanes".

I don't think a steam boiler would be effective for use in a plane... the boiler undoubtedly weighs more than the thrust provided by that engine.

I am a fan of steam power, especially green steam.

A solar boiler is a great idea for powering a generator, but boy my neighbors would hate me with all that racket. Sure love the rhythm of a steam engine though.

Can anyone find hard data besides steam pressure or engine weight on that site?
Any kind of motor/engine can be built so that it weights only one pound, the question is how many kW do you get from it and how efficient is it?

The only thing I see is some pictures without explanations and a lot of text without any information. Sounds total hoax to me.

I've seen that before, and even if it does work, I would not buy one.

Why?

Durability.

Look at how many oddly moving(un-lubricated) parts are inside that engine.

A regular steam piston engine is very reliable.

Even a make-shift steam turbine made from an Automotive Turbocharger is extremely reliable.

I'm not sure how long a machine like this would last, if it even does produce useful mechanical power.


Personally, I have plans to build a Solar Thermal collector (in a trough design) and it will feed 300+ degrees F steam into an automotive turbocharger (a cheap turbine) that will turn automotive alternators to generate electric power.

The poor-man's steam power.

This system will also take the waste steam from the turbine and condense it back into hot-water(via automotive radiators for condensers) to supply hot-water to the house.

Or be routed into a steam-fed indoor radiator system to heat the house in winter.

I plan to have 100+ square feet of solar troughs to collect a massive amount of heat from the sun, using cheap(and replaceable) Mylar Flexible mirror.

This system can also provide distilled fresh drinking water or
Refrigeration(and air conditioning) via an absorption refrigerator (a heat powered refrigerator, like propane-powered ones in RVs)

If you want to see more, check out http://www.solarturbinegroup.org/
They're already doing it in South Africa.

If they can do it, why can't I?

Why not recycle the waste heated water back into the loop so its already preheated.
Im looking at using an old 8ft satellite dish as a collector/reflector for my steam powered turbine.
Its pretty easy to track the sun with it.

The system I plan to build will have a very large heating capacity.

I plan to have a closed-loop system for the turbine, to make it most efficient.

And all distilled water production will have as much waste heat recycled as I can. (which means the radiators might not be used)

It'll be a massive plumbing project for sure, my problem is figuring out a way to automate it.

Have you ever run the #s to see what efficiency it will operate at?The dish Im going to use first is about 32 sq ft.
How big of a "collector" will I need to create enough steam to power a turbo turbine like you mention?

I'm thinking of doing the same. In the winter I will need power to heat the compartment and maybe the batteries too, no point in wasting away the heat from the controller then.

And yes, major plumbing galore. Not sure how to pull that off...

I think the inventor of the Aircar is working up to a motor like this. He has already disclosed that he needs to heat air to extend the range of the car. He's just a hop skip and a jump from reinventing the steam engine
