1879年美国著名科学家爱迪生制成了实用、价格低廉的白炽灯。人们在欢呼、庆祝这一伟大成就的时候,富有远见的科学家已经看到白炽灯明显的不足之处,它只利用了电能的10%~20%,其余80%~90%的电能以热损耗的形式被浪费掉,能不能开辟一条电能利用的新途径呢?
In 1879, the famous American scientist Edison made a practical, inexpensive incandescent lamp. When people cheered and celebrated this great achievement, visionary scientists have already seen obvious disadvantages of the incandescent lamp. It only uses 10%~20% of the electric energy, and the remaining 80%~90% of the electric energy consumes heat. Is the form being wasted, can we open up a new way of using electricity?
