There is an idea in the field of Geo-Engineering that says reflecting some of the sunrays back into space is a possible solution for Global Warming. The idea of Geo-engineering is usually only of interest to venture capitalists, scientists, and of course engineers. However, I think there is great value in everyone, adults and children, to learn about and brainstorm ways to save our planet.
My Sun Reflector, which is precarious and impractical in several ways, seems to be the work of a backyard tinkerer. Yet, it is built fearlessly, with the materials I find, and the technology I know. It uses water and floatation, tension and gravity, handmade parabolic reflectors (which bounce and focus sunrays forwards) and bamboo (an incredibly strong and sustainable building material). This was my first idea for a sun reflection device, but new ones are in development. I am envisioning new simple devices in the upper atmosphere of the earth, or orbiting the earth in outer space.
