正文摘要:這種獎勵真的有利于推動綠色環保嗎? 日本最近開始為公民提供“生態點”購買新的電子產品,提供減稅購買生態車輛。有助于提升經濟困境。美國緊隨其后,通過了“超耗油付錢”法,獎勵美國人購買小排量環保車。旨在推 ... |
風電啊,適合風大的地方,還要考慮小氣候問題、上網電價問題。不過核電、風電不管哪頭熱,國內都沒有核心技術,樂的還是外國公司 |
確實如此,水電站受氣候的影響很嚴重,核電站的效能會更好的,而且處理得好的話,是綠色的能源!! |
核電應是環保能源的唯一選擇。太陽能和風能發電都是不錯的產業,能廣泛解決就業,但商業利用要做的還很多。北京市就有需要大約上萬臺風車。出北京在張家口可以看到很多,但是上萬臺,場地在何處?不要跟在奧巴馬走,中國還是搞核電比較合乎國情。 |
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. |
自行車最環保而且無污染,可惜騎的人越來越少 |
有人說,電動車很環保,但生產電動車的過程是否環保呢?蓄電池的生產、報廢是否環保呢? |
看完了~~~ 那天在馬路上,看見一個交警領著一個小女孩過馬路,那剎那真的蠻感動的~!然后頭一轉才發現對面有個人交警拿著相機在拍照~! 我 靠 這也太假了吧... 這也搞作假,真是服了~! 可以試想..... |
