Sare research about natural cells tells too, that foundation hives had on average 1% drone cells compared to 33% in foundationless hives.

Where did he get the 30% more honey calculation from? was it 30% more than a hive that swarmed ? or a hive that swarm prevention was adopted by the beekeeper ?

I do not understand what that Gene story is doing in the research or weigh of bees.
.
And some made 40% more wax... What they did?

I think he was doing some sort of biomass calculation as a comparison of the colony's "investment" in drone brood and worker brood.

It's a real pity that the translation is so poor because the research (60 colonies over 6 years) and practical application (3600 beekeepers successfully using the method) look promising.

Blessed beekeepers..

How many in Britain do Bailey comb exhange?

The good news is that it is well known that varroa do not like high temperatures:
“Varroa mites prefer temperatures between 26 and 33 _C (Le Conte and Arnold, 1987, 1988; Patzold and Ritter, 1989; Rosenkranz, 1988), which are significantly lower than the normal temperature in the brood nest of approximately 34.5–35 _C (Becher and Moritz, 2009; Rosenkranz and Engels, 1994). Varroa mites are able to discriminate temperature differences of about 1 _C (Le Conte and Arnold, 1987).” (from P. Rosenkranz et al. ‘Biology and control of Varroa destructor’ Journal of Invertebrate Pathology 103 (2010) S96–S119)

See also US patent Beehive heater US 3994034 A and try Googling the website for VarroaController both of which seek to damage varroa by heating the hive typically above 40 Celsius.

The bad news is that such temperatures can also damage the sperm stored within the queen, typically sperm viability drops to 20 percent from about 90 percent.

Main point in heating treatment is that who uses it as routine beekeeping.

That sperm thing is very easy to handle when you do not heat hives of mating stations.

"damage the sperm stored within the queen,"
so not just mating stations

I think the answer to your question is "people who keep bees in Thermosolar hives" - see http://thermosolarhive.com/en/thermosolar-hive/technology/in-a-nutshell/
