Comment Re:Transformers are efficient (Score 1) 221

But in a transformer the coils are very close to each other, and are wrapped around the same lump of iron. With the devices the coils and cores are separate. Magnetic fields decay exponentially so even a small gap will reduce the transmitted power by a fair bit. There seems to be various proposed methods to get around this problem, but none of them seem to be significantly better than the others.

Interesting point about electronics reducing the idle currents, as this would be another issue.

Submission + - Amazon.com Suing Statsaholic

SwollUG writes: Amazon.com offers several highly innovative and useful web services (S3, EC2, and Mechanical Turk, to name a few), but do troubled waters lie ahead for users of these services? ZDNet's Alan Graham has the scoop on Tim O'Reilly's confrontation with Jeff Bezos about a lawsuit filed by Amazon's Alexa against Statsaholic, a popular web traffic comparison site built on the Alexa API. GigaOm's Om Malik has referenced this as a harbinger of the end of Web 2.0. Is this what happens when your Amazon-based website starts becoming popular? Say it ain't so, Amazon!
