太阳能是环保能源,需要大量空间场地和太阳能板,以及电力存储和变送电设施。若商业利用成本则不会低于固体燃料。近来科学家研究直接将光能作为动力驱动电机,nanomotor纳米马达。感兴趣可以看看。
Solar power is one of the most intense areas of research around the globe as scientists and researchers look for alternative power methods that will free society from fossil fuel dependence. As solar panels become more efficient, they can generate more power making them a viable alternative.
Typically, using power from light involves capturing and storing that energy in a battery or other device. However, a group of chemists from the University of Florida has developed a new nanoscale motor that is able to turn light directly into motion. The researchers point out that the discovery is on a "very, very, very small scale."
The nanomotor is not the first motor to be driven by particles of light; it is however, the first nanomotor built entirely from a single molecule of DNA. The simplicity of using a single DNA molecule reportedly makes the nanomotor easier to manufacture and develop. |
