Using The Physics of the Parabola to Build a Homemade Parabolic Signal Collector
A Homemade Parabolic Signal Collector is a Great Project.
The mathematical beauty of a parabolic reflector is described by what it can do. Energy of all frequencies can be collected and reflected to a single point as long as you are using the right material in the design.
Signals such as sound, radio, microwave and light can be reflected and concentrated in this way.
Buying a parabolic reflector is not so easy but it turns that making a small sized one is really very cheap and easy to do. In this video the team from Green Power Science shows us how to make a parabolic collector from simple material and components that you may have around the house or can get at your local hardware store.
In this design, you will need a garbage can lid and some aluminum insulation material and some glue and of course the know how to put it all together.
The finished design can reflect sunlight but be careful not to use it in direct sun because it can really burn you. If you are looking to make a solar cooker this is the business end you will need to do it.
You can also use this a cell phone signal booster if you live in a hilly or forested area without direct access to phone tower signals. It may be enough to get you from 3G to 4G.
