nano tubes

The next electronic break through: carbon atomsCarbon can be made to form tubular structures. These tubes are called nanotubes.

When two nanotubes that are slightly dissimilar are joined together, the junction between them can function as an electric device. The electronic behavior of the device depends on the detailed structures of the two tubes. When nanotubes are formed, they conduct electricity like a metal. When they are twisting distortions in the structure, they conduct current differently more like semiconductor materials that are used in microelectronic circuits.

company uses fuel cell to get energy

The arrival of electric cars has been delayed for years by problems in finding a suitable energy source. The batteries that are available at reasonable cost have been too heavy and take up much space. Up until now successful fuel cells have required the use of fuels such as hydrogen and oxygen. Oxygen can be obtained from the air, but hydrogen is expensive to produce. The us department of energy and A.D has solved the problem by finding a way to extract hydrogen efficiently and cleanly from gasoline or ethanol, and this process is called “reforming”. So gasoline or ethanol can in directly become the source of hydrogen for a fuel cell.
