Water fountains bring a sample of nature’s flowing water into our built environment - from hotel atrium to living room. They add visual and audible interest to any setting and remind one of the waterfalls, creeks, and oceans. Floor fountains are larger, freestanding units designed to be placed on the floor, not on a table. They often serve as a foc...
Door knobs are one of the main elements to open the door. It is used to hold the door as well as open it and lock it. There are different types of door knobs- for adults’ bedroom, children’s bedroom, bathroom doors, garden doors, main doors. The door knobs being an important part of the door have many shapes in it. A doorknob is a type of handle wh...
Record high prices at American gas pumps and continued trouble-brewing in the Middle East, Nigeria, and other areas of importance to the oil-driven economy have made it clear to Americans that we are in need of developing many new avenues of energy supply and production. In short, we need to reduce our dependency on oil, for it is ultimately finite...
There has been much debate about what is often called “free” energy—energy that can supposedly, with the right technology, be drawn straight out of the atmosphere, and in very abundant supply. The debates are about whether the stuff actually exists or not, what it would actually cost were it to be harnessed, and if it does exist is it truly as abun...
Ocean Thermal Energy Conversion (OTEC) was conceived of by the French engineer Jacques D'Arsonval in 1881. However, at the time of this writing the Natural Energy Laboratory of Hawaii is home to the only operating experimental OTEC plant on the face of the earth. OTEC is a potential alternative energy source that needs to be funded and explored muc...
It is possible to have a portfolio which profitably (that's the key word, is it not?) invests in alternative energy funds. “Green” energy production is expected to be a multi-billion (in today's dollars) industry by 2013.
The most recently developed wind-turbine technologies have brought us wind-produced energy which is more cost efficient a...
There are many different forms in which alternative energy is available.
One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar energy power can be used for electricity, heating, and making hot water. Solar energy produces no pollution, as it...
The trend toward homes that are powered by alternative energy sources, ranging from wind turbines and solar collection cells to hydrogen fuel cells and biomass gases, is one that needs to continue into the 21st century and beyond. We have great need of becoming more energy independent, and not having to rely on the supplying of fossil fuels from un...
