That oatmeal comic is ridiculously inaccurate and in the author's rebuttal he pretty much says as much. Please stop posting it as it has done huge damage to the conversation on Edison vs. Tesla. Just one quick example: in the comic it implies that Edison, out of some sense of rivalry with Tesla, used his position on the naval board to prevent Tesla from getting a grant to utilize Tesla's method of submarine detection. Tesla proposed using radar to track the submarines which the naval board rightly rejected as radar is quickly attenuated underwater.

There is a bit of a nasty strain of hero worship in some parts of the tech community.
