About 60 to 200 miles overhead , the particles bump into the earth 's atmosphere and become electrically ' excited ' - throwing off light of various colours .
在约60至200英里上空,粒子与地球大气层发生碰撞,受到电气激励发出各种颜色的光线。
Morse operated the treadle the graphophone was not electrically powered-and on his return to london delightedly showed henry edmunds the product of his labors : " a small black cylinder with a few black spiral lines traced upon it containing the record of the voice and speech of the celebrated queen . "
But batteries are improving , and if they were good enough then an electrically powered helicopter would ( like an electric car ) be a more elegant solution to the problem of locomotion than the serial explosions that keep an internal-combustion engine ticking over .
Hamilton said there does not appear to be a common thread linking the electrical problems . One of the many innovations with the composite airliner is its extensive use of electrically powered compressors in many systems , including de-icing and cabin pressurization , instead of jet engine " bleed air .
