From the article:
"These black holes are 25 times more efficient than anything man has built, with nuclear power being the most efficient of man-made efforts, said study lead author Steve Allen of Stanford University and the Stanford Linear Accelerator Center."
A typical light water power reactor and generation system has an efficiency of approximately 28 per cent. Now, the claim of efficiency of 25 times that is puzzling, because the process would be about 700 per cent efficient. In other words, for every joule of energy put into the system, you would get 7 watts out.
I am wondering if the reporter garbled what was said.
I don't know, that must be how they get a billion miles per gallon of gas.
What was said in the article was just plain dumb. I doubt that any real scientist could distort the information as bad as this article, so it must be the author. Calling it garbled is kind.
