Thomas Edison’s original ‘idea’ has finally come to fruition. He want to power homes and buildings with DC because he was afraid of AC. Telsa was the expounder of AC wiring because of the ease of which it could be transmitted over long distances with little loss. If Edison had had his way there would have been a generation plant on every block, since DC has such large line losses.
We had to wait until the 21st century for technology to develop efficient devices that allowed them to shrink to micro size in order to fulfill Edison’s dream.
I fully expect that within the next few years all new houses will have built-in USB cabling and a home +5V power supply permanently wired in to all rooms just like the normal AC, audio and TV cables are now.
The next obvious step is microwave wireless power distribution that you can sync into and not even have the necessity of a cable..........................
People have already created wireless power distribution. That's the goal of some inventors. Some devices can "grab" energy from all the electromagnetic force that penetrates our airspace. My wife looks at this as a bad thing. She believes all this unseen stuff criss-crossing our airspace is causing illness in people, possibly even causing cancer. After all, our bodies are partially electrical and prone to interference from electromagnetics. Get exposed to a high-energy microwave burst and your body will get cooked. Get exposed to high-energy electromagnetics and your cells will go haywire. So perhaps wireless power distribution is not such a good thing. Incidentally, she worked for our utility company, PG&E, was exposed to a lot of EMF and retired early due to cancer (several types of cancer).
Regarding Edison and Tesla, I'm well aware of the history, having read much of the wars between them. Edison was not afraid of AC, he was an opportunist who wanted to make money and tried everything to discourage use of AC in favor of DC. He hired goons to kill animals under AC power lines and then influenced media to report that AC was dangerous to people as well as animals; that unseen AC energy was killing the animals. Edison was an evil man. DC has always been in use within short distances of the power generation, but AC ruled for distances greater than a couple miles. Reason being, energy loss of DC being converted to heat by wiring resistance. Devices that convert from AC to DC are still inefficient, perhaps converting only 80 percent of the energy. Have you ever pulled a wall wart from the wall outlet and noted how hot the brick is?
