Solar "Preheater" Air Heater

diy solar air preheaterThis solar air heater is made from just $50 worth or reused materials and provides a very significant heat source.

The solar "preheater" feeds an existing air exchanger in this R2000 home, increasing the input air terperature by 20 Celsius (36F).

Wind Turbine Furling

You worked hard building your DIY wind turbine and now you look forward to days when the wind blows hard. The power output increases as a CUBE of the increase in wind velocity - a 3 fold increase in wind speed means a 9 fold increase in power output.

Problem is, your DIY wind turbine won't survive very many of those "extreme" wind days. You need a way to protect your wind turbine from high wind damage, while allowing it to still produce power at the top end of it's output curve. You need to FURL your wind turbine in high winds.

Build an Axial Flux Alternator for Wind Turbines

DIY Wind Turbines are very popular and usually very quick and simple to build. The permanent magnet D.C. motor has a lot to do, with making this process EASY. However, good D.C. motors (Ametek 30), that produce a workable voltage and current, at low revolutions per minute (rpm) are becoming hard to find. Ebay is loaded will people selling motors for wind turbine projects, that simply WILL NOT WORK at the rpms that a homemade wind turbine can produce.

A homemade axial flux alternator could be your best alternative. While the process to make your own, may seem complex, why not give it a once through. Some of the plans on the internet, show you how to make top of the line jigs and tools, which can be reused many times. If you only want to make one or two alternators, the steps can be simplified.

No Cost Ways to Help the Environment

  1. Reduce, Reuse, Recycle - starting with reduce. Lower your carbon footprint by carefully considering each purchase. Is this a “want” or a “need”. Can I get it in good used condition from someplace else? Does it have minimal packaging.
  2. Operate your large electrical appliances in off-hours. If you use a dryer, run it in off-peak hours. (using a clothes line is even better)
  3. Turn down the temperature on your hot water heater.
  4. Make your own household cleaners. It’s easy and quick. See for recipes. low flow shower head
  5. Shorten your shower times and take fewer baths. (if you buy a low flow shower head you can greatly reduce your hot water usage and keep those longer showers).
