you can read a much more detailed analysis on the US Patent website---Bill Low patented this technology.
First, a patent doesn't mean anything. You can patent anything you want. It doesn't have to work or even do what you claim it does.
Second, there's no analysis at all in the DBS patent (7,126,055 for those interested). Low simply makes a number of unsubstantiated claims. You might as well read their marketing literature.
I did find one thing of note in the patent however that relates to something I'd said previously:
"In other words, and as indicated above, cables of this type may be thought of as long capacitors being gradually charged (i.e., "formed") by the electrical signal as the signal is communicated along a conductor surrounded by an insulating dielectric material."
This makes it pretty clear that Low has a rather basic misunderstanding with regard to dielectric "forming" and doesn't realize that this is something that only relates to aluminum electrolytic capacitors.
