Solar "Preheater" Air Heater
This 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).

Electric Vehicle EV Battery Reuse
Battery systems in electric vehicles are expected to outlast the vehicles themselves. Thus at the end of the car’s life, the battery system should still retain 70% of it’s storage capacity. These used battery systems would not be strong enough to power another new vehicle but could they be used for home power systems?

DIY Solar Water Heater
We have several DIY solar projects including solar ovens, solar pool heaters, solar PV panels solar air heaters and batch solar water heaters. We have just added another solar water collector - a bit more involved than a batch water heater or "bread box" water heater. Take a look at this design by Jake Teaters.

Grow Your Fresh Air With Houseplants
As we made are homes and workplaces more energy efficient and air tight, the quality of indoor air greatly decreased. Use these houseplants to remove indoor air toxins. Plants are ordered by their ability to remove chemical toxins, how easy they are to grow and their resistance to pests.

How Home Solar Photovoltaic (PV) Works
Interested in a small solar photovoltaic (PV) project for your home, cottage or camp ground? Here’s a quick overview of how it works and how to setup your own small solar PV system.
How Solar PV Works
Chickens Chickens Chickens
Having mastered the backyard garden, most people wishing to grow or raise more of their own food, add a few chickens to the mix.
Green Driveways - Grass Pavers
Green driveways reduce storm water runoffs and the pollution that carries as well as reduces the island heat effect of large dark surfaces.
VAWT- Ready for Testing
We have finished our first Vertical Axis Wind Turbine (VAWT). However, we still have concerns about our gearing system. Once we have some test results, we'll be sure to post them here.
DIY Solar PV Panels
We take a look at building your own solar PV panels. It's a very nice project - requires soldering skills and a bit of woodworking and you learn lots.

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.

DC Wind Turbine Motors on eBay - BEWARE
DIY Wind Turbines have become very popular items in the past year. We have DIY plans forboth horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT) on this site. And yes, in the beginning we recommended people take a look on eBay for used DC Motors to use in their DIY Wind Turbines.
Unfortunately, as the demand for DC Motors has increased, so has the supply “of inappropriate” motors.

DIY Wind Turbines
As the price of electricity rises, so does the interest in making your own windmill or wind turbine. We have designs and links for the do it yourself builder for both:
Vertical Axis Wind Turbines (VAWT)
Horizontal Axis Wind Turbines (HAWT

Electric Plug-in Vehicles
Electric plug-in vehicles are available today, that can travel over 100 kms (60 miles) before a recharge, with top speeds exceeding 100 km/h (60 mph). Even greater ranges and speeds are on the horizon.

Just how much Power is in the Wind, for producing electricity? - Wind Turbines
There's just a little bit of math involved, but you can easily figure out how much power a small wind turbine can produce, given the length of the blades and the wind speed. With this information, you'll know if you should listen to that Salesman, or walk away.
How Much Power is in the Wind
Step by step instructions with parts list and tools list. Makes a great science project.
- 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.
- 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)
- Turn down the temperature on your hot water heater.
- Make your own household cleaners. It’s easy and quick. See http://greenterrafirma.com/cleaners.html for recipes.
- 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).
