Can flags be used to collect solar energy?

This morning I heard John Oakley, the host of a morning radio show on AM 640 Toronto Radio, blatantly express the possibility of using flags to collect solar energy. The remark occurred after a local politician was said to be stepping down, but still wanted to continue a project constructing the largest flag in the world. In the past, solar panels were not considered to be ‘flexible’, but in today’s market flexible solar panels exist.

Hence the creation of a flag with solar panels at the back, and the country’s banner at the front, should not hinder the flag’s natural movement in the wind. Considering the fact that sunlight is prevalent in some parts of the world more than others, such as in countries near the equator, this could just be one way to harvest energy and show your national pride at the same time.

As ridiculous as it may initially seem, there is a market for such a product. Schools, government buildings, and large offices are just a few examples. Once the product is designed and the technology is validated via testing to ensure sustainability and safety, the potential outcome could alter the way we look at a seemingly ordinary flag pole.

2009: International Year of Astronomy

2009 has been recorded as the International Year of Astronomy. Yet the concept of astronomy as a hobby is often seen as one that is too challenging, and too expensive, for the average individual. The purpose of this post is to dispel those rumours. According to the homepage for the International Year of Astronomy (see link below), ”Astronomy is a science which embraces modern technology…”. It is seldom required to have a telescope for practical astronomy as thanks to the advances in technology and the manufacturing process, it is quite possible to have a pair of binoculars that allows you to see the surface of the Moon and potentially planets like Venus.

 

The cost of participating in a hobby like astronomy, can greatly be reduced by attending local venues for that subject. Sticking with astronomy, visiting a science centre or planetarium, where they will often have telescopes for public use, might be the best way to quickly educate yourself in the chosen subject, while you make new connections through academics and hobbyists alike.
