Novel steam engine

What do you think of this crazy looking engine.

And a steam engine that powered an aeroplane.

 Mentor Interesting innovation, but it is still a steam engine that works on the same basic principle that drove trains 150 years ago. It is long obsolete. And the reason they never worked for airplanes is that the power to weight ratio is far too low due to the fact that you need fuel and water and a boiler and an engine, whereas you could burn the fuel directly in the engine (at higher efficiency), and get rid of the water and the boiler.

Awwww, Russ you big kill joy, you are supposed to wax lyrical about steam
engines, they are big kids toys, and are getting lighter

Novel steam engine

Instead of smog we can have fog.

 Not bad, quite interesting. Though I do wonder how well the flex will stand up to use. I didn't notice any provision for waste steam porting/valving for condensate return. Sort of reminds of a design in one of my old P.M. encyclopedias. Russ: Steam is making a comeback of sorts. There are some experimental models for personal vehicles. Though I do doubt that they will be on the road anytime soon. However, some smaller sawmills still use steam power, largely because it is economical for them and works well. I was at the Paisley Steam Show last summer and was quite impressed when the sawmill bit into a hardwood log without slowing down. http://www.bruceheritage.org/
 Mentor Steam itself isn't outdated, it's reciprocating steam engines that are outdated. Steam has been driving turbines for decades.
 Mentor Blog Entries: 9 Hull Oaks Lumber is located in the southern Willamette valley is noted for its steam engine. A significant benefit it the that they fuel it with sawdust. One could say that HP has made billions and billions  off of steam engines in the last 20 years. A Thermal Inkjet pen is a very simple steam engine. The work done is squirting ink.

And what do you plan on burning to ensure that we won't have smog? Water?!

 Russ: While your statement is generally true, there is still a use for reciprocating engines. While they are less efficient than turbines they are generally able to take more abuse (looser tolerances) and keep running under conditions in which a turbine would experience a rather abrupt expansion. Recips are still in use, notably in small sawmills and the Third World.

Is this possible?

 Quote by david_india Is this possible?
No for two reasons:
1. It is prepetual machine, the battery is running the burner, and being charged by power output from the turbine. This is not possible because you can't get more energy out of the steam engine than you first put into it as heat. In reality you will get much less based on the system efficiency.
2. The pump (compressor in your diagram) is in the wrong spot to be a proper Rankine-cycle steam power system. The pump needs to be located after the condenser before the boiler, and would have to have some power input. See: http://en.wikipedia.org/wiki/Rankine_cycle

 Thank you for your reply Mech_Engineer. How about 4-stroke spark ignition gas engines. I mean they get the power from the battery to the ignition coil and to the rotor which distributes the spark into the cylinder which runs the engine; and the engine runs the alternator which recharges the battery. Why cant this be possible in steam engines. I really appreciate your input. Thanks again.
