A DIY Tracker Tough Enough for the Arctic

Cars That Think

But it’s a tough environment for scientific instruments. So, I set about building an open-source ice tracker from DIY components that not only proved to be much, much cheaper but also much more capable than the commercial options. This is fast enough to identify wind waves, which typically have a frequency of about 0.2

Why I'm not an Environmentalist

DIY Electric Car

My concern for the environment started when earth, fire, wind, water and heart combined to fight the forces of corporate greed and irresponsibility. How can I care about the environment on one hand yet refuse to join the ranks of like minded individuals on the other? Tags: Environment Green Living.

Advantages And Disadvantages Of Electric Cars

DIY Electric Car

Its engine does not emit any harmful byproducts like smoke or other emissions that pollute the environment as it runs on clean energy. Electric energy produced by thermal, wind, hydro or solar power plants do not cause any pollution either. Pretty futuristic, huh!
