Post wireless power transmission
The RSGB, in common with the whole of the International Amateur Radio Union, IARU, has serious concerns about wireless power transmission.
Studies of its impact in the residential environment suggest that there are likely to be harmful levels of harmonic interference to existing radio services such as amateur and broadcast.

RSGB EMC Chair Dr Martin Sach, G8KDF joined the IARU team at the recent CISPR standards organisation meeting in Korea to represent our concerns. Work is also underway in CEPT and ITU, where IARU is representing the concerns of the amateur service.

As yet there is no reconciliation of the positions of the wireless power transfer device manufacturers and the radio services likely to be affected. Many of the issues are set out in a consultation document from CEPT that can be found at tinyurl.com/GB2RS-0411A

There are certain topics which could be brought up in defence of our spectrum

Conversion efficiency.., but this would need to be explained in words of one syllable so that the man in the street can understand it.

Health and Safety, the localised E/H field around the charging pads will almost certainly exceed the ICNRP limits by a wide margin, anyone know a reporter at the Daily Mail / Express?

The only mention of conversion efficiency I've seen was a manufacturers claim of 'up to 40%'. Which sounds both vague and poor.
Electric cars only look more eco-friendly because they push the pollution further up the supply chain.

Has anyone seen figures quoting magnetic field strengths around charging stations? Does anyone walking around with a metal clip on a brain aneurysm need to steer clear of them?

A crucial point in history where you could benefit from Nikola Tesla on complex subjects like these because the current level of intelligence in the industry is sub-standard at best.
Like PLT, VDSL and other "illegal" data transmission mediums a simple brown envelope will be passed under the dinner table over Champagne and Sirloin Steak paid for by the tax payer, do not illude yourselves that the likes of OfCom and the RSGB have any form influence on theses matters any more than the electorate has the ability to choose their own government! :banghead:
