Vedenkeittimestä.
Tästä linkistä löytyy asiasta 'jotain' (Peter Davey). Tämän muusikon 'pallolämmituin ei ole se jota tarkoitin.
lyhyt sitaatti:
So he found two tops from old bicycle bells, joined them together, tuned one of them to 50 Hz frequency, attached electricity wire to each one of them, and thrown them into water. Surprisingly, water started to boil extremely fast. So he made his first heater patent based on this observation. This patent was already registered in 1944. After a hero return from the war, he had a device, which repetitively proved to everyone who measured it, that it has the efficiency decisively exceeding 100%. Realising this, he believed that the world is going to pounce on the opportunity of production and use of this technical miracle. After all, people are full of declarations about apparent saving on energy, resources, about protection of our natural environment, etc. However, the reality turned out to be completely opposite. Immediately after it was experimentally confirmed that the device has unexplainably high efficiency, the heater and the inventor fell into disfavour of various institutions that are interested in selling electricity and that protect the monopoly on electrical power. In the result, this extraordinary invention received an extraordinary treatment! Namely authorities were doing everything in their powers to disallow the production and sale of this heater in New Zealand. One of legal tricks that were used against this heater, was that it was declared officially to be "unsafe to health and life of users". (Please notice that practically every electrical device working on 220 Volts can be declared unsafe, if someone in the position of authority wishes to put it down.)

Puolivälistä sivua löytyy 'fillarikello' asiaa.
(Siellä on myös mainittu Esa Ruoho, mutta linkki ei johda mihinkään.
http://www.rexresearch.com/davey/davey.htmSe minkä luin aikanaan ei kuitenkaan ollut juuri tämä, mutta tässä puhutaan nimenomaan
samasta asiasta. (Kyllä mä sen 'alkuperäisenkin vielä löydän....).
