A Way to Make the Smart Grid Smarter

New solid-state power-management devices will charge cars fast and make the power grid more flexible and efficient.

Interesting stuff.

I see maybe a hundred components in that set-up, perhaps more.

Whereas in a traditional transformer, there are 3 (essentially): the input coil, the output coil and the soft iron core assembly.

The only way a traditional transformer will fail, is if one of the wires in either core fails (melts).

And in the old "electric wars" which pitted Edison against Westinghouse, Westinghouse won. (Edison was pushing for direct current, while Westinghouse opted for the cheaper A/C).

One of the reasons why Westinghouse won against Edison's DC, is because with AC, changing the voltage from one 'size' to another is quite simple, if not all that efficient.

I'm all for innovation, but reliability is just as important as efficiency.

And my opinion of complex electrics is not very high-- how many times have you heard about needing to replace a PC power supply? With me-- all too often for such a simple thing.
Quantum Junction: Use both lanes

Reality is that which is left, after you stop believing.
