The Overbalanced Wheel is an example of perpetual motion, the oldest attempt at a perpetual motion device in history. The oldest known description of on is from 8th century India- a wheel with vials of mercury arranged in such a way that as the wheel rotates, the mercury sloshes away from the center on one side, but towards it on the other.
Now these days we know that the perpetual motion is heavy and expensive, and dangerous. That’s why has been replaced with shifting mallets, but the principle it still operates the same. Perpetual motion describes motion that continues indefinitely without any external source of energy; impossible in practice because of friction.
For millennia, it was not clear whether perpetual motion devices were possible or not, but the development of modern theories of thermodynamics has indicated that they are impossible, despite this, many attempts have been made to construct such machines, continuing into modern times.
Solar power is starting to become mainstream. The “green” movement has taken hold and we are beginning to see its accomplishments. Solar panels are used commercially, industrially, and residentially. Unfortunately, it is still quite expensive to install and it can take a while to see the savings, though be sure they are there.
If you would like to show your support for the green movement but aren’t fond of the spending required to make your house green all at once, consider do-it-yourself solar projects for use in your home. You can slowly make your house “greener” and get a new hobby at the same time. You can purchase solar kits and cheap panels to install yourself. Maybe you’d like a solar water heater or just enough electricity from solar energy to power your computer and other electronics. Look around online to find fun projects to help the green movement and make a difference starting in your own home.
In 2009, wind power sources provided 1.9 percent of the United States’ power production. While this may seem like a new fangled technology it’s actually one of the oldest forms of energy in existence dating back as far as 5,000 B.C. sailing ships.
Wind power is actually a form of solar power. Heat causes the wind by producing varying levels of heat in different areas and high pressure air always moves towards low air pressure areas. While solar panel cells take in the heat and rays directly, the byproduct of the heat on the earth causes the movement of air that is translated into power from the wind turbines.
From 2000 to 20006 wind power production has actually increased four times over. This is a great trend considering that one Megawatt of wind energy actually produces 2,600 tons of Carbon Dioxide fewer than conventional power sources.
Texas has jumped on the ball more than anyone, installing more wind generators than any other state in the U.S. which includes 37 other competing states.
