105. YOU are the alternative power!

http://www.electric-bike-kit.com/solar-tubes.aspx

In Stock! Now Shipping!

Excellent for winter heating systems and summer projects. Boil water using only sunlight! Use this box of 10 tubes for your own science or hobby projects, or for building your own powerful solar-powered home heating systems.

...

Each solar evacuated tube soaks up the energy in sunlight, absorbing it into the super-insulated inner tube of their incredible double-wall heating system. Once inside, the heat of the sunlight is trapped inside the inner wall of the inner glass tube, creating a powerful solar thermal collector. Highly-reflective layers of steel, aluminum, and copper trap the infra-red energy of the sunlight, and the nearly perfect vacuum between the inner wall and the outer transparent wall protect the inner tube from heat loss due to convection, just like a high-grade drink thermos. This thermos effect can quickly heat water to boiling temperatures in direct sunlight, and keep the water well over 100 degrees, even over night! Perfect for you DIY, home improvement, solar hot water heater.
