太陽能是環保能源,需要大量空間場地和太陽能板,以及電力存儲和變送電設施。若商業利用成本則不會低于固體燃料。近來科學家研究直接將光能作為動力驅動電機,nanomotor納米馬達。感興趣可以看看。
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. |
