第959章 世上真有电灯吗？（第2页）
“电是一种能量，就像咱们蒸汽机能够运转，需要烧煤，产生热量和蒸汽，来推动蒸汽机运行；而有了电能，便不需要蒸汽机，机器也能运转
杜景眼睛一亮：“当真如此神奇？”
杨林点点头：“不止如此，电只需要通过一根金属线，就可以延伸到千家万户，通过这根线，每个人都能够轻易摄取并使用电能
杜景歪着脑袋，却还是想不通，问道：“可是这样，家家户户用这个电又能做什么呢？机器这东西，只有工坊能够用得到，总不能家家户户，都有机器吧？”
“这你可说错了杨林笑道，“怎么不可能家家户户都有机器？”
“嗯？”杜景百思不得其解，“家家户户都有纺织机？这不可能吧？”
如今靠山村的纺织厂里，己经有部分机器，从三代、西代织女纺织机，更换成了蒸汽动力的纺织机，不仅降低了成本，而且工作效率还得到了大幅度提升！己然让杜景意识到，机器就是未来的生产力，而蒸汽机就是机器的终极形态！
而如今，杨林竟然又要鼓捣什么电能？
杜景不太相信，这个什么电，能比蒸汽机还厉害，更不相信，未来家家户户都需要纺织机！
杨林再次笑笑：“谁说机器就一定是纺织机了？”
“那还能有什么机器？”
“很多杨林说道，“比如帮人洗衣服的机器，就不需要人再用手辛苦清洗衣服了；再比如用电和锅结合起来，就可以用电做饭，再也不用生火烧柴了
“我们还可以发明一种用电能的灯，只要通电，它就会亮，而且比烛光亮上百倍！黑夜里，也能亮如白昼！”
杜景瞪大眼睛：“电……灯？世上真的有这种东西吗？”
