　　就在美国国际商用机器公司进入其第二个世纪时，这家美国技术公司公布了它的第六个五五计划，一份关于5项创新技术的清单，公司预期将在五年之内实现这些创新技术。其中的一个会帮助我们产生少量能量来补充家用电能。伯尼•麦叶森是IBM公司创新部的副总经理，他说：“你可以用微电子产能。比如第三世界的一个人，他有电话或者是智慧手机，但是却没电了，这是个很常见的事情。而你可以给他一双鞋子，可以通过走路就能产生能量并且可以充电，从而使那个人继续和外界保持联络。”另一个创新会使那些难记的密码过时。很快我们就会利用名为生物测定学的技术来进入邮箱或者银行账户。“想象一下，事物能够辨别出你，当你走到取款机前，它看你一眼然后就说‘是的，是你本人。’”
