How to Build Very CHEAP Solar Panels and Wind power Generator and Cut your Electricity Bills by 90%

How can we build power plants for solar energy, which will cost less for developing countries?

Mirrors and water tanks. Mirrors shine light on black painted water tanks. Water in tanks boils, steam runs a turbine which turns a generator. They have already built some plants like this in the US, the one I know the location of is in California, just north of Kramer Junction on US 395 (Death Valley). Of course, the enviro-nazi’s will not let the California government BUILD any more of them…heavens, it might, might mind you, distrupt habitat for the Desert Tortise! Heavens to Mergatroid!! GASP, not the tortise! Can’t do that, cannot take the RISK that MAYBE it might affect habitat.

I started working on commercial scale wind turbines in 2006. There are STILL people that INSIST that the wind park I work at has driven all the animal life away from that area. Crap. Daily, we have to stop/slow down/swerve to aviod Elk, Deer, Moose, Red-tailed Hawks,Bald Eagles, blue birds, etc. (or just sit and watch while taking a break up tower, no better place to watch eagles and hawks flying from!) People blow my mind with the BS they get all wound up about.

Oh yeah, wind turbines do not slay birds by the thousands like some folks would have you believe. I have never seen a bird carcass on our site, I have heard of a few at other sites, but not many.

Sorry for the rant, think I pushed one of my own buttons there! lol

Many people living in cities are itching to take advantage of residential wind turbines, but this may prove to be difficult.  Cities are some of the least hospitable places for wind turbines to be located.  Wind turbines work most efficiently when placed in undisturbed airflow.  Any large obstacles nearby, such as buildings will greatly affect the amount of power that a turbine can produce.

To find a suitable residential wind turbine, the best option may be a vertical axis wind turbine or VAWT.  You may have seen these turbines before, most commonly they are shaped like large egg beaters and spin around a pole mounted vertically.  This is in contrast to traditional wind turbines which have propeller-like blades.

Vertical axis wind turbines have much better performance than traditional wind turbines when used in turbulent environments.  This means that in a residential wind turbine application, a VAWT will provide more power than a traditional turbine.  There are many different styles of VAWTs and each has its own advantages and disadvantages.

Savonius type turbines are completely solid, and don’t have blades as you are used to seeing.  Instead, a Savonius turbine has two (or more) curved surfaces which face the wind full on, and spin the turbine about its axis.  These turbines are large and heavy compared to other aerodynamically-driven turbines and are also less suitable for use as residential wind turbines due to their size.

Darrieus type wind turbines are the egg-beater style VAWTs mentioned earlier.  These turbines have curved or even more complex blades to take advantage of turbulent wind conditions.  Traditionally, these turbines have been very large.  This means that their suitability as residential wind turbines is limited; however they are more suitable than Savonius type turbines.  These turbines do have several issues which make their design more complicated.  Specifically, the turbines generate maximum torque at two points in their rotation, and thus the power they generate is not “smooth†as it would be in a traditional wind turbine.  Additionally, these turbines have issues with vibration that could cause the blades to fail prematurely.

Finally, airfoil based wind turbines, which are a subset of Darrieus turbines.  Instead of curved blades, the blades of these turbines are parallel to the main shaft.  This means that they generate more constant power than Darrieus turbines, much closer to traditional wind turbines.  These turbines are the closest match to the requirements of residential wind turbines.  Much research into this type of turbine is ongoing and new developments are happening in this field every day.
