'Wireless electricity, auto elettriche, solar pond - Un nuovo mondo possibile' - Casa senza fili, e-mobility, autonomia energetica - Esperimenti di elettricità secondo Tesla", dated 16.04 (2011). - The conference took place on 15 April 2011 (Sala Confindustria, Verona), organised by Heos Editrice and Gruppo Giordano. Speakers: Franco Bonfante (vice-president, Veneto regional council), Marco Tornaghi (Thermogea srl, solar ponds), Ing. Bruno Giordano (Gruppo Giordano), Pietro Menga (president, CEI-CIVES Milan), Giovanni Pede (ENEA), Giuseppe Buja (University of Padua), "Roberto Handwerker, Delta Ingegneria - Busto Arsizio (Va)"; moderator "prof. Giovanni Bignami, presidente del COSPAR" [web: same URL]. - On Handwerker (translated from Italian): the conference closed with his talk; after a brief summary of Tesla's work he moved to experiments in wireless power transmission "which caught the attention of the audience". He showed a halogen lamp, "unusable in a normal setting because 'burnt out'", lit in a basin of water, into which "to demonstrate the strangeness of Tesla's electricity, he put his hand in the most absolute normality". Also "the experiment of transmission of electrical power which made a small toy car without wires and batteries move". The reporter: "What practical developments these experiments may have, it is still too early to say." - Heos is published by Heos Editrice, Isola Rizza (Verona), registered at the Verona tribunal (n.1258, 7 March 1997).
Bearing on the claims
A dated, named, public demonstration of the lamp-in-water and wireless toy-car effects (claims 3 and 5 family), reported by a co-organiser of the event (an interested party in the event's success; it also published Handwerker's articles). It records what the audience saw, not measurements; no independent check of the set-up (power source, return path, frequency) is reported.
