No doubt, the importance that people attribute to electricity is that it
makes possible so many other inventions.
Edison made only one purely scientific discovery regarding the strange
force we call electricity. That discovery, appropriately called the Edison Effect,
involves the flow of electricity across a vacuum. Edison patented the discovery
but could find no use for it and went on to other things. The Edison Effect
turned out to be the basis of what we now call the electronics industry: radio,
television, computers, and video cassette recorders.
Today electricity continues to occupy centre stage in the creation of new
technologies.
In light of today’s challenges, electricity is not simply a great invention. It
is a miracle fuel: a highly efficient energy source that’s clean at point of use,
that helps cut atmospheric carbon dioxide, and that can be controlled to
hairbreadth levels of precision.
Someone once said that efficiency means doing things right and
effectiveness means doing the right thing. I say the key to both is electricity.
The fuel of the future.
