横流式涡轮机
有两种不同的涡轮机设计,一个用于低压,另一个用于高压应用。我的涡轮机叶片被设计成产生升力,象飞机的机翼,因此,水的流速从前缘的上方和下方流动到后缘使压力差在上(外倾角)和加氢的低级(和弦)升力面刀片,从而创造一个升降的结果。

Crossflow turbinesThere are two distinct turbine designs, one for low, the other for high pressure application. Contrary to some individuals who claim that Crossflow wheels are impulse wheels, my crossflow blades derive their power by reaction not impulse (impact).  My turbine blades are designed to create lift, like an airplane wing, thus the water velocity flowing from the leading edge over and under to the trailing edge causing a pressure differential in the upper (camber) and lower (chord) lift surfaces of the hydro blade, thereby creating a lifting reaction the result is much extra torque to the shaft. As evidence to my statement check out my Prony brake test. 
If you want to create electricity without building the Bedini self running energizers, but having a creek on your property with a head (drop) capable over ten feet I suggest you build amedium pressure spinner with three RPM setting 1/3%, 2/3% and 100% full open with stub shafts, whereas for a 6" pen stock you would build an high pressure 8" runner,  also no shaft through the center of the runner and not as wide. 
______________________________________________
In the other hand if you are reading this page just for the sake of interest to create your own power but are having no creek flowing through your property, then the self running Bedini window motor, the self running John Bedini Monopole at my Schematics page INDEX (oo) or the self running magneto energizers at the same page INDEX (xxx), might interest you. Especially the window motor if you like  Hugh Piggott's energizer. Looking at the good torque reach and high rpm the window motor will produce, which by the way will create its own power (no I am not kidding), a high efficiency output of the alternator should be ideal from all perspectives. Also with a single rotor the tuning of the alternator is made easy by adjusting the rotor position/distance relative the stator. 
If only the lack of experience in electricity is holding you from jumping at it with "all four", then just read through my work shop and schematics illustrated and start from scratch. Study the novel principle of extracting Radiant Energy or cold electricity from the air by creating a sharp gradient and shocking the RE into existence through DC pulsers or transistors for your own use. By the time you have read all my Bedini pages and have practiced  some of the switching procedures, you'll be ready to build your own electrical energy generator, I mean creating your own power. 
I do not belief in the term of free energy since no gadget is falling in your lap for free, you'll always have to sweat and reach into your pocket, be it by building it your self with the needed shop equipment or farming it out, unless you try to buy it for big bucks and get taken*$%^.

Three foot head
Keep your formulas in your pocket and listen to my practical reality talk. The 26" 16 blade low pressure wheel 12" wide, a 9-1/2 chord, 3/4 draft and (D) opening of 1-3/4" on a, three foot head would get you between 4 and 10 Ampere through a one by twelve foot culvert 1/3d volume of water. Even though the 12" intake of a 10 foot pipe is fully submersed (1 ft below the surface). The outlet volume of the creek can be controlled seldom more than 35% of its diameter, except in runoff on higher water volume when you could let the 12" penstock rip full force to which the site was not designed for though; shut off, flow/vacuum and water level is therefore controlled with a peace of 3/4 plywood at the intake of the penstock. You can't have air in the penstock if you want to make use of the full head pressure...and that is not always possible!! In the dry season for instance. 
In any case, I haven't seen an average of 7amp output in any table or performance sheet on a 3 foot head with that small amount of water, in fact I haven't been able to find any Data below a 6' head of water.
In a low pressure dam setup you use sometimes every drop of the creek water, whereas  with a high pressure dam and full headrace with a steady penstock pressure, all is totally different, in which only a small percentage of the creek water is being used. For low pressure without a gate one can design a smaller pipe and run it full flow, except when the water level in the dam drops to a certain point where the intake will suck in air, hence  you run out of vacuum/siphon effect and torque, then the pipe is to small because of the water/air or even ice mixture.  Yup, I'm not kidding, when winter weather conditions are accordingly, the whole creek is full of ice crystals mixed in with the water just like a freeze drink.
The output depends on the volume of rain, snow fall or frost/ice, water volume of the creek and level of the dam, which is the reason for the big diameter penstock and wide margin of the power performance. 
The above low pressure description is my turbine and it is running to this day and the Frenchmen who is running and enjoying the "free electricity" !!*???#^  is busy doing it.
