The world’s first single-molecule vehicle has been built using nano-technology. It has a chassis, pivoting axles and rotating wheels. Measuring about three to four nanometers across, it is slightly wider than a strand of DNA. The synthesis and testing of nanocars and other molecular machines are expected to provide critical insights in the investigations of bottom-up molecular manufacturing.

Man would eventually need to move objects and do work in a controlled fashion on the molecular scale and a nanocar is a great test bed for that. It is capable of rolling on its wheels in a direction of right angles to its axles. When tested on a gold surface at room temperature, strong electrical bonds held the wheels tightly against the gold but heating to about 200C enabled them to roll.

There is a wave of very distinct color sweeping the world today and that color is green. We are all trying to be more environmentally conscience and do our deed to help save the planet. But this often seems to come as a contradiction to our modern way of life. All around us we are consuming more and manufacturing more products from inorganic materials such as plastics and polymers. But that doesn’t mean these products can’t be green. In fact, there is no contradiction today at all between being green and enjoying high quality plastic products. With today’s technology, you can achieve some of the highest quality High Density Polyethylene which is the material from which modern plastic is manufactured. The process involves refining HDPE regrind, scrap HDPE into HDPE Granules. The HDPE regrind is washed and processed to remove most of the contaminants and then shredded into small strips and flakes. The resulting HDPE Granules is then reprocessed to create the same high quality HDPE which our products are molded from.

Long before gasoline became readily available, leading automakers thought ethanol would be the world’s primary fuel. It is a high octane fuel that helps prevent engine knocking and is extremely important in engine designed to operate at a higher compression ratio thus generating more power. These types of engines are most likely to be found in high-performance vehicles.

Due to its high octane nature, ethanol is sometimes blended with gasoline in small amounts to boost octane rating. High-performance engines will benefit from this mixture. Ethanol is primarily produced from corn or sugar crops either by dry-mill or wet-mill processing. At present, dry-mill facilities account for more than 80% of the industry’s capacity in spite of the relative popularity of wet-mill facilities during the early days.

Once the generators of the Three Gorges Dam are in place and go online on 2009, it will be considered the world’s biggest power plant. It is expected to generate 18.2 GW or about 2% of China’s total power consumption. China’s booming economy needs to be matched by power; preferably alternative forms of energy that do not pollute air.

Extra precautions have been taken in the engineering and fault tolerance of the dam. Its other purpose is to engage in flood control. Regulation of the flow of water is made possible because of the massive 22 cubic kilometers reservoir. When fully flooded, the dam’s reservoir will be 200 meters deep.

Adding a renewable energy system to one’s home or business may entail high initial costs but may be the biggest step anyone can take on lowering environmental impact. The high cost anyway is likely to be offsetted by savings or utility costs over the long term. Government has also been offering incentives that can shorten the time necessary to offset the cost of such technology. Once the system is in place, it produces virtually free energy.

The renewable energy system may not be appropriate for everyone since there are certain factors that need to be considered such as the availability of net metering in an area, the types of technologies that will work best in a specific location and the financial options available.
