Darrieus Hydro Turbine

[homskoult]

If vertical axis turbines were effective in water, boat propellers would be obsolete. Urban509 is right about the horizontal axis, however, cupping the blades and only submerging the part of the lower blades that create power would be better.

Do you have a pic of the turbin out of the water? Thanks:)

[smellycatpoop]

This will never work!

[CoyoteBoyUK]

Seems most people here have no idea how a Darrieus generates it's rotational force. Good work, nice little test rig.

Nobody will EVER use water for energy!!!!!!!!! this is stupipppppppppiddd

@photofox1985 are U drunk?

[maka666]

@photofox1985 burning salt water will never be the next big thing

[damedosmates]

@photofox1985 idiot

@photofox1985 Obviously you are a twenty five year kid, that quit school at 6 years old. Did you ever see a picture of a hydro electric plant that uses water to turn a turbine? Go check out Hoover Dam. Your friggin computer is probably running off of it right now!!

[shotsxxx]

@photofox1985 I do hahahahaha

[MoviesAndGamesTV]

@photofox1985 lol you are stupid!!!! you see wath happen to Japon ????? fukushima

[walperstyle]

Congradulations, you figured out the basics of how a Hydro-electric Dam works, only the dam upstream is actually producing power, lol.

I'm all for the little guy getting off grid, but you've got a long way to go from watching this video.

Try a larger water wheel, standing on a different axis much like they use to use in the middle ages. You will find less resistance then your current setup. If you don't understand what I mean by resistance, ask me, I'll draw a picture.

Questions and comments:

1. Are you shielding the 180-degree side that rotates back against the river flow?

2. See all that turbulence at the surface? It is also turbulent all the way down to the bottom. You need to eliminate the turbulence - with smooth flow in and out. All turbulence is energy lost.

3. You can ALSO funnel MORE water at it, which will increase the water's velocity at the vanes, meaning more HP.

How did you get that out into that part of the river? Boat? If so, that looks deep there...how tall is the device? It seems to be touching the bottom, but how is that so if the water looks so deep? It must either be anchored down or weigh an awful lot, which would seem awkward to get it out there on a boat.

300$ excluding the cost of that river, of course we exclude that because that would be too expensive!

This dude is right!

should of built it upright with a plate on the back diverting water into the bottom spinning the wheel round a horisontal axis. would of spun allot faster without resistance in the opposite direction.

[lastmondaypast1]

lol thats true, thats how they did it hundreds and even thousands of years ago for mills.

[EltonMD]

Tu trabajo me asqueo

[marinerodeaguapura]

all is not generating... turbine must be studied for get better work!

[montrealbroadway]

how much electricity is this producing?

[Holsterinalaska]

None.

I built this as a platform to test different variations of the turbine... ex.. blade placement, rotor diameter, etc.

[lauragravesfain]

That is so inefficient. Go back to school.

[MrFrais]

Bravo!!! More!
