Solar Air Conditioner - Solar Evaporative Cooler

We made a solar air conditioner using an existing evaporative cooler. We power the solar air conditioner with a tracking solar panel. Solar cooling and air conditioning is possible.

CEILING FAN ALTERNATOR AC to DC Power Supply Converter

This is a DIY alternator that contains 2 sets of coils. Only one set is used in this video. These are standard wall power supplies that are used for household DC rechargeable appliances.

How I built my first V.A.W.T. Vertical Axis Wind Turbine

Home Made Wind Turbine

Lynx Vawt with new airfoil rotor vanes

For Plans: go to this website and scroll to the first post in the thread. I highly recommend the smaller 4'H x 3'D version seen in the video. Just adjust the dimensions.

In this video you can see the increase in speed from the re-designed rotor vanes. The vanes are angled in a way you wouldn't think would work. The airfoil gains lift as the rotor spins. The airfoils are cutting a path around the turbine and lift is at a slight tangent to the axis.

Homemade Wind Turbine Generator VAWT Vertical

Homemade Vertical Wind Turbine mounted behind my wall and isn't visible from the street. Perfect turbine for HOA areas and in cities that won't allow mast mounted turbines. This is a wing lift prototype I'm getting some numbers from to create an improved designed. I believe these are the future of wind energy. I also have so other alternative energy concepts on the drawing board I'll post in the future. This intellectual property belongs to myself. However, please feel free to use this design for non-commercial purposes (your own home turbine). © 2009-2010 imikewillrockyou

How to build a solar water heater

Trade Secrets - Solar Hot Water Systems

solar water heater simple DIY project

A short video showing the small solar water heater i designed a couple of days ago. it consists of 136 feet of 1/2" black tubing. internal diameter is actually 3/5" (cost approx $10.00), 4 connector pieces (to connect the various pieces together and to connect it to the house (cost approx. $5.00)), and finally the 'y connector' so i could have the garden hose hooked up at the same time (cost approx $5.00). all purchased from home depot. total cost was approx. $20.00. all i did was coil 100 feet of the hose and attach it to a piece of plywood. after 30 minutes of sun the water temperature is about 130-133 degrees and after 60 to 90 minutes it can reach 150 degrees. the tubing can hold about 2 gallons of water at a time. if you drain and refill several times throughout the day you could easity get 10-15 gallons of hot water a day. of note: they call the tubing 1/2" but the actual internal diameter of the tubing is 3/5" (.6 inches). 100 feet of tubing holds 1.47 gallons and 136 feet of tubing holds approx. 2 gallons. home depot sells a 500 foot roll for about $35.00. that would hold 7.36 gallons of water.
