Here are a few solutions that can some of the problems to solve..
Surely you will need to test them in practice, before se makes the right decisions as to the shape of the structure of the drive.
Perhaps such a solution with a single tube might be the most efficient, because it will most laminar flow
Or a Cutter Heron
Of course, a whole can be properly enclosed guard areodynamic...
Well, here an example, if the electric drive can also adapt to the helicopter. Turbine itself would be inside the helicopter, but it would not be permanently linked to the rotor, so that no torque moved...

AndrewNice idea, but I doubt it would run an electric oven, shower or heating system (or AC!) for very long.
There are lots of proposals for these types of systems, in the US some energy companies are filling containers with batteries to use in load balancing systems for the grid. (This is effectively what you are doing, but on a local scale), mainly in flat areas where they can't install a hydroelectric solution.
The primary issue is conversion efficiency, going from AC->DC + Charging, then DC -> AC you typically lose iro 20-25% of the energy in conversion.
There are proposals to create a DC socket standard for homes for low power systems that can work well in DC such as electronics and lighting. The problem with this is you need to rewire your home.
The other fundamental weakness with this system is the same one experienced by electric cars, battery life, yes lead acid is cheap (relatively), but if you're changing the batteries every 3-4years it outweighs the savings in electricity. They are looking at a lithium solution that should hopefully work for 20-30years, but these are not suitable for cars.

I have my car Mercedes 508 D from 30lat. I purchased the two batteries Bosch 1A (headless) with up to 100Ah, in 1995, which is a good 15 years ago. Today I have them in the car, although in Poland severe winter.
I think, with such new batteries housed in the home where the same temperature and daily regular load, can calmly work is by some 20 years.
You can of course put with two or three such systems versus demand. The heating also.
And of course, this is the system ready for solar and other power systems. ...

A home electric shower, cooker or heating system are in the 10Kw region, @ 12v dc this is 833A continuous for sustained periods, hours possibly, not including conversion losses.
Big Automotive DC batteries can deliver this current, but only for short periods and the voltage is quite low so you don't get the total power output.
Higher voltage would reduce the current draw, but the batteries are not designed to operate in these conditions for sustained periods.
Repeated high current charge and discharge cycles wear the batteries out faster.

I was with my friends in the Museum of aviation again. "I'd like him to show this demo in which the effect of the vacuum State at the top of the wings, which blows the wind from the fan, the ball is sucked in by a transparent tube
provided in the middle of the wings and a peg that pops up on the wing.
Doing this experience again, so your friend can see it, I am surprised that the ball a is NOT sucked in tube!!
It is that this experience has been vandalized, and the ball is not sucked on
Vandalized based on this, with a transparent tube to the bottom was several times the seeds.
But this was not the reason for the lack of vacuum in the tube.
After arrives home, thoroughly by looking at the about the well running the show.
http://www.youtube.com/watch?v=Fb8IFfnbjY8&fea...
I noticed that the tube on the film extends over the upper surface of the wings have 70 mm
The vandalizet show the tube was brought down to equality with the upper surface of the wing.
And this was the main reason for the lack of vacuum in the tube !
Simply air her upper surface of the wing, when it encounters a simple hole in the wing, just get it and seeking to keep the pipes, eliminates any vacuum in it.!!
That is, that the ball could be the suck by the vacuum arising at the top of the wings, in this case the pipe must extend over the upper surface of the wing by about 70 mm !!!
When this tube does not extend, this does not transmit its down this vacuum, even in the smallest degree.
Why is this, explain the following drawings:
Yes so we are one of the one cases where due to vandalism, we fully the specificities of of the Red Baron Windmill...
According to estimates, the surface of the wing of a 100 m square, with a wind speed of 30 km/h can produce approximately 750 KG lift.
To get 100 KG of thrust of the propeller to the ultralight trike, the engine must have a power of about 50 KW
We can also assume vice versa that the 100 KG lift gives us 50 KW electrical dynamo.
Which had managed to seize the entire lift such 100 m ^ 2 wings which is 750 KG, a power Dynamo would be 300 KW.
The Windmill of the Red Baron 100 m x 30 m = 3000 m ^ 2 and this will give us the 9000 KW.
Now you can build 10 such wings one above with which 30000 m ^ 2 = 90 MW.
No and now depends on how many% of this theoretical power we capture this lift and exchange it into electrical current.

I think the era of steam comes to an end. At most in obsolete nuclear power plants will be still used. 
Half supports the engine has one very big advantage. Piston not friction on the walls of the "cylinder""Only the seals frictions cylinder
Thanks to these properties, the engine may be running on ... the coal dust.
Rudolf Diesel's first engine was built just on the coal dust, but unfortunately zacierał is at work. In the case of half rotate, will not look any login problems.Simply does not have any large surface friction
Only the directory should be chosen for personal seal. Each round you can straighten lines, of course, resistant to coal dust.....

Star engines were characterized biggest always force density
Below picture of the star half rotate around 10 (40) with "cylinders". for the transparency of the picture one can see only 3 additional "cylinders" more than is at the animated film.
One can also see dimensions of the whole of the engine in the assumption that every cylinder has such dimensions for the picture half rotate with the set connecting rod of the Sulzer D= engine of 900 mm and stroke 2500 mm .
So 10 (40) "cylindrical" engine half rotate about the same working capacity in comparing to the Sulzer 10 engine cylindrical on the picture below .
Sulzer: 10 Cylinders 20 m long , 15 m hight , 1500 Ton weight
Half rotate star : 10(40) "Cylinders" 4,5 m diameter , 4,5 m long

And most importantly.. Since in the engine half rotate mass innertia are several times Sulzer smaller than in the engine, engine half rotate can work with the much greater rotation speed.
Slzer : 102 RPM 60 000 KW
Half rotate 250 RPM 150 000 KW

And now, the efficiency of the engine, due to the friction of the walls of the cylinder to rise about 5%. That is, it is the most efficient machine for the heat, whose efficiency exceeds 50% of the.
