Hello

I am planning to start beekeeping just as a hobby, one or two hives in my garden. I have found some new type of hive - thermosolar hive - which is now sold through crowdfunding Indiegogo. It can cure bees just with the sun, they say. It interested me because I don't want to cure bees with chemicals. A friend of mine, experienced beekeeper, told me that without chemicals bees not survive, is it true?
