Stuart and Cedar Anderson are a father and son team of professional beekeepers. They've developed a new type of beehive that they call Flow. The Flow hive is built with partially formed cells. When bees take up residence in it, they make use of this pre-existing cell network. With the turn of a spigot, the cells split open, dumping their honey down a channel. There's no need to open the hive and scrape off honey off individual frames. They can fill two large jars of honey very quicky using a Flow hive.
I was interested in bees in high school, when I found a wild beehive in a nearby hollow tree, and I got to reading about them.
The queen excluder allows a beekeeper to isolate the queen in the lower part of the hive, ensuring that the upper combs have honey and no larvae.
So, in the thousands of years of bee cultivation, the real killer innovation was the observation of the 'bee space'
I thought that the best hive innovation would be the bee smoker. Y'know, so you don't get stung by bees.
