Hot Water Bottles and NHK World
Fascinating. I just watched a short program named Japanology on NHK World. The topic was hot water bottles. It appears hot water bottles are making a come back, and there are many different forms being reproduced and innovated. The potential for better warming at a lower cost is high, as well as the ability to use these heating sources in novel locations, such as bicycle taxis and disaster sites.
