I work in concrete so I know how to keep the walls from cracking. There have been some major evolution in concrete within that past few years and it is now the most versatile building material. Several colleges across the USA build canoes every year out of concrete and race them in canoe competitions. Countertops are being made from concrete and when done they look like granite. Houses and other buildings are being pre-cast in concrete and then set up in a day. It can be insulated, painted, waterproofed, decorated, stamped, and dyed. It can be made to withstand as little as 1500 psi and as much as 15,000. It can be designed to weigh 4000 lbs per yard or as little as 400. It can take 28 days to cure or 24 hours. I could build one form and pour hundreds of hives for pennies each, saving time and money over conventional hives. I do not see it as re-inventing the wheel as much as it would be revolutionizing beekeeping.
