A promising technology?

I recently read about this company called Levant Power. Levant Power was formed by two MIT students who were trying to find a solutions to allow cars to be more efficient with fossil fuels, due to the fact that cars only use 20% of the energy available for every gallon of gasoline it burns. They came up with a shock absorbing system that takes the energy from a bump in the road, and transfers the energy to the drive train to help propel the car forward. Their tests have show that this system can save 3% in fuel cost and allow for cars to be more energy efficient. You may think 3% is a tiny number but just think how much fuel that actual is if this system was put in all cars. This may not be a solution to global warming, but it definitely helps curb our foreign oil addiction.

real vs. artificial christmas trees

Every year, families from all over, traditionally go out, cut down, and drive home a christmas tree to place presents under. My question: Is it more sustainable to cut down a tree every year, or buy one fake tree that you may have forever.  

Fake trees: They are produced in factories by the thousand every year. chemicals, plastic, metal, and huge delivery trucks are only a few processes. While your not cutting down “wild life” every year, the fake trees, are not able to be broken down if you decide to throw it away.

Real Tree: While they are being grown for 6 years on a lot, they produce oxygen and take in carbon dioxide. But at the same time, they are sucking nutrients from the surrounding areas to the hundreds of trees on the lot. The trees then must be cut down, and driven by the people purchasing them, and then watered every day to keep them alive for a few weeks or so. 

So which is more sustainable?

Eco-Footprint

Here is a cool website I came across that you can  you can calculate your eco-footprint by answering just ten questions.  It then offers ways to lower your footprint.  Also on this website there is a carbon calculator you can use to calculate how much carbon you would use if you decided to take a trip or for many other different situations.

Coca-Cola’s New Look

The classic Coke can is getting a new look.  The original can was painted red and white, but now Coca-cola is thinking of making the can unpainted.  By not painting the can Coca-cola saves energy and paint.  This will also eliminate the paint removing step in the recycling process.  This change will cut back on air pollution, water pollution, paint, and it will save energy.
