On any given day, the weather trend is usually the first subject of conversation. During the past month, anywhere you go in the United States, the price of gasoline has become a primary topic to complain about. Most people, and businesses, feel helpless when looking toward winter’s fuel bills.
Will dispensing oil from the Strategic Petroleum Reserve help us? If you think short-term – Yes; it will help temporarily. (more…)
Mechanical energy is an area of science that is making strides every day. The study of how actuators produce mechanical motion by converting various forms of energy into mechanical energy is a source of great exploration. Science finds new ways to make use of actuators every day including for medical purposes. Many scientists believe that the more they study these seemingly simple machines, the more they will discover ways of helping mankind.

With more and more people living longer and longer, the question of quality of life is a constant concern. Some older people choose to grab life by the horns and soak up every second. Others are simply unable to do so. Still others choose to let little things get in the way of living and then watch as these problems snowball to take away their mobility and independence. For those who want to enjoy life to the fullest, sometimes a little help is needed in the form of devices such as electric wheelchairs, walkers and so on. (more…)
More and more scientists today agree that global warming is a serious issue and that the cause of global warming is carbon dioxide released into the atmosphere when fossil fuels are burned. Politicians, too, are being swayed as they see increases in property damaged, injuries, and even deaths due to natural catastrophes which appear to have gotten worse in recent decades.
Because fossil fuels appear to be the source of worldwide atmospheric change, people have began to look to other methods of producing energy. In addition to causing atmospheric change, there’s the reality that we will run out of fossil fuels. The world’s economy is based on fossil fuels but they are a finite resource. Eventually we will run out of them. Fossil fuels are not a sustainable resource. Two methods of producing energy which have little impact on the environment and are sustainable are solar and wind power. (more…)
Solar power has been available for decades. Safe, relatively clean energy, but the cost of the panels has long been too high for the average consumer. They’re also the one problem with solar energy, for those wondering about the relatively clean energy part. But the recycling of them should improve over time.
Many people would love to go solar in their homes. It’s a practical energy source in many places, even ones where you wouldn’t expect it to do all that well. And in places where homes aren’t built near a pre-existing grid, solar power is often much, much more reasonable than having wires run out.
The fact that energy prices have been steadily rising also helps solar energy appear more reasonably priced. The cost is almost all upfront, which is perhaps the greatest challenge. A good solar power system sufficient to heat the average home in the United States runs many thousands of dollars. However it also offers tremendous savings over time. (more…)
