Going Green with Our Homemade Wind Generator

going green with wind energy I don’t care about what they write about other countries, given that they couldn’t get a very simple fact right about France, a country where the tax rules are documented and easily available. Yours truly is a design engineer and recognises this bearing issue as just another bit of engineering reality that loads up the Cap-ex and the repair and maintenance costs of this hair brained technology and its submerged cousin, wave power. There are no market forces in favor of wind energy. During low demand times (especially spring runoff) in western Canada/USA, mandated, extremely expensive wind power is forced onto the grid, driving grid prices down into negative territory. This ignores the fact that wind energy is a very old technology – 14th century perhaps.

Using 22 rpms (at about 30 mph wind, which they avoid operating in, I believe), and running 3/4 of the time, 90% of turbine bearings should last for about 10 years. So using the other rule, even a little bit slower can help a LOT. And if the wind averages only 15 mph, the life span should be 20 years for 90% of the bearings, etc. Situations of low or zero wind in which the blades stop for considerable periods of time, making the actual flattening of balls/rollers and indentation of cages not possible, but likely. Operation in an area of inevitable wind shear as blade tips approach ground level so that cyclic thrust and torsional load variations will inevitably happen. Massive gyroscopic effects if the head assembly needs to be slewed through azimuth to meet the actual wind direction when operating. Its a totally useless way to generate minuscule amounts of electricity at massive costs. The future is different.

Obviously it has to fit with some room to move freely, but even if it is a lot thinner, the wind turbine will remain reasonably upright when the overlap is long enough. I set up the (hand) mitre-saw with a guide so that they could do the sawing, and we used a drill-stand with a template much like yours for the generator and rotor holes. That gave the holes in acceptable positions and meant that the wiring could be along the lines of “orange motor wire into the orange hole” etc. In theory combining two different metals leads to corrosion of the least noble one. But in practice, I expect you will not have corrosion problems within the lifetime of these wind turbines. PS we used 50cm lengths of pipe over 120cm bamboo canes with your marble bearing and they turn fine in the wind. Hopefully we can do these generators but either way, I am completely stealing this wiring method! Attach the generator to the head shaft.

It is my understanding that significant transmission efficiency losses are associated using hydraulic motors and hydraulic lines as power transmission coupling devices, with the energy losses appearing as heat in the transmission fluid. There are other tax credits that are not Oil Company specific. The nominal rotor speed of the turbine is 10.5rpm.

The Low Wind Mallard LW is a great starter generator for those who have never used wind generators before. It will generate electricity in as little as 5 MPH winds and can tolerate wind speeds up to 60 MPH. For the past 18 years my family has been living Off-the-Grid with only wind energy and solar, powering our home. We can live off-grid with solar and wind generated power that we can build ourselves. We know this works because we have done everything that is shown in their Homemade Wind Generator Plans! People like you, who have been held down and robbed blind by the power companies.

You see, we were like you… just regular people who wanted to lower their expenses, especially high electricity costs. These guys have made the process easy to follow – even a complete novice will be able to follow these homemade wind generator blueprints and plans. Total cost project was £190. Live and learn.
