I saw an episode of "Penn & Tellers BULLSHIT" last night. The show was about the truths and myths of recycling. Is recycling a benefit to the environment and does it save natural resources?

Which ever view you take, one interesting fact popped up: 40% of all of the recycled trash ends up in a landfill site anyways.It turns out that aluminum cans were the only thing that is being recycled at a profit. It simply costs more to recycle paper products than what you can buy wood which was grown on a tree farm for just this purpose.

Using trees as a renewable resource is not only a better bargain it also saves the environment from the chemicals necessary to bleach and process recycled paper. Other recycled products cost more to transport, sort and reprocess than they ever will fetch on the market.

One of the biggest drawbacks with electricity produced by windmills is that the price per Kw falls the harder and longer the wind blows. Since there is no way to regulate the output from windmills it would be nice to be able to somehow store the energy until prices are high enough.

This is an interesting design challenge as well as a huge business opportunity.

The price the electrical utilities pay per kW of electricity from windmills fluctuates considerably minute by minute. During peak loads the prices are higher, at night time the prices are lower. Power stations conserve energy by turning production down at night, (un)fortunately nobody can increase or decrease the wind to regulate the output of windmills. The consequence is that windmills sell a large portion of their output at very cheap rates.

By the end of 2007 there will be 1 billion camera phones in existance. The sale of mobile phones with a camera have skyrocketed from 3 million in 2001 to 500 million sold in 2006. In 2006 there were sold 1 billion mobile telephones worldwide, half of which were camera phones.

Lets take a moment to grasp this: It took Casio 30 years to sell 1 billion calculators. I don't even think McDonalds sold a billion hamburgers that fast!
