"Equipment found in any college science department can be used to transmit electric signals at four times the speed of light." Buried at the bottom of the article is the disclaimer:

"While the peak moves faster than light speed, the total energy of the pulse does not. This means Einstein's relativity is preserved, so do not expect super-fast starships or time machines anytime soon.Signals also get weaker and more distorted the faster they go, so in theory no useful information can get transmitted at faster-than-light speeds..."
