This simple cable can greatly reduce exposure to electrosmog for those working at a computer for long hours.
Most computers do not have an earth connection to their chassis. This means the keyboard and mouse give off a typical electric field of 400 Volts per metre which is 400 times the “no concern” level of the building biology standard. Fitting this simple cable, by plugging one end into a standard electric socket and the other into a USB socket fixes the problem.
Using this on a computer will also earth the shielding of ethernet cables and reduce the radiation from networks.
