A scientist in Tashkent has a hot-box with a temperature of437 F (2) inside it -that is (3), two and quarter times the temperature of boiling water. His box has eight sheets of glass. Another Russian scientist has made the simplest type of a solar boiler. It is a box about 16 feet long, seven feet wide and some seven inches high. On a sunny day, it can heat 150 gallons of water to a temperature of about 140 F. The top of the box has two sheets of glass, with a third sheet on the bottom. Inside the box are fourteen rows of half inch iron pipes, with lengths (4) of rubber tubing connecting them. From one side the heater takes in (5) cold water, from the other the hot water runs out. The whole, process is automatic. This boiler has become very popular.
