I believe Mariah energy in northern Nevada tried a design like this. The solid curved “wings” came off in a prototype installed at an elementary school in Las Vegas. They modified their design to curved “blades”. Look at their web site for the current design. Gusting winds can put a lot of unstable pressures on these devices.

A small turbine located inside the engine compartment using a scoop and duct system for airflow is feasible.

The amount of materials and machine shop time/labour that go into this machine vs. the relatively minuscule amount of power out makes this a big loser. Furthermore, this drag turbine in a new package technology is certainly not *new*.

Brendan,

I would like to point out something about the conservation of energy, though you are right about the closed systems. You seem to know your physics, so I’ll try to be spesific and brief.

Consider a car. It pushes air away, which turns kinetic energy of the car to that of air. Air then gives room to the car. I find this energy could be used. Though this is only for the air moved by the car body. Maybe for some design this power is more than the additional drag? (not much, i think, but there has been talk about something like this.)

But then again air above and next to the cars passing track. That air is still, and then you come driving at it with your windmills on the roof. You move towards the air to make it feel like its windy. Common sense says there is no potential.

Correct me, please!

I’ve dug into these. Apparently, they don’t deliver the power stated on their wesite according to some customers and cost like $20000. Buyer Beware!

I am a rancher in south Texas 7 miles from the gulf and all ways have a good wind. And also we have a large high elect line down the middle of the ranch. I need to know who I contact about wind turbines? Thanks for your time. James

There are several erroneous comments above. A wind turbine on top of a moving vehicle would slow it down, and use energy. However a solar cell roof might help. Wind turbines could not be installed on existing tall buildings, as they are not designed for these large forces. It is suggested that in 5 years flat panel voltaics will be cost effective. One of the problems with wind turbines is that they are required to pat about a 2% higher interest rate than power plants, & this makes them less cost efficient.

Hello,
Could some one please contact me from your office I would like to talk to them about more information on wind turbines we are a custom composite company needing advice on types of generators
Thank you

I’m a student in debate and I’m writing an affirmative case over this, and I need to know how many jobs this could potentially create when they’re at full production, and if you find how many jobs it’ll create, can you provide me the info so I can use it as an evidence card? Thanks

Sir,

Congratulations for developing unique design especially for urban and rooftop conditions.

Pl inform performance of this innovative design wind energy generator.

Kindly keep me on your mailing list for further developments. I would love to have one for my building.

Turbine on top of a car, now that is funny. Yes it will generate power, but more power will be used up by the engine to counter the drag. Everytime you transfer the type of energy to another you lose some. So overall it will lose energy.

If you had a device that could generate more power than drag then yes, but seeing as that is the opposite of how wind turbines work…

Vertical Axis Wind Turbines like this are not new, and I do not see this design variant as ground breaking or “next gen”. VAWT wind turbines have their place, but any design for low wind must be able to survive when the wind picks up! Else you know what will happen.

Regular large wind turbines could have these along side supported by the same tall post, increasing total output.

To SR,

Actually, the famous law of the Conservation of Energy is fatally flawed, contrary to mainstream belief. It only works for closed systems. A moving car is anything but a closed system.

And as far as wind turbines on car roofs are concerned the main drawback would be the wind resistance created by the device, adding friction to the entire system. Cars already lose the majority of the energy (chemical-thermal-kinetic) used to power them through friction, turbulence and heat. The idea of catching some of that and redirecting it back into the system is not new, and does have potential.

I have 9 houses on 2 ac and I have “The Trade Winds”; what would it cost for the turbine? I can do the rest.

How much to buy and install ?
Do you export to Perth Australia ?

There’s a law against that.

No, The BIG MONEY OIL LOBBY did NOT spend
a fortune to bribe Congress….

It’s one of the laws of the
Conservation of Energy.

Would it be practical to attach a smaller version of the wind turbine to the top of an electric car. using the constant wind traveling at say 60 mph to generate electricity to recharge the batteries?

Are there any wind turbines like this for residential use? That seems like the next logical step.

I would be curious about the variability of wind speeds in urban areas. Also, I wonder if these would be more cost-effective than wind farm models?
