DAB uses too much energy
If you look on the Specs for the Freeplay Devo wind up radio it shows that a 60 second wind will power the radio in FM mode for 1 hour but the same 60 second wind will only give you 3 - 5 minutes of DAB radio. From this it would seem that a DAB radio uses at least 12 times more energy than a standard FM radio. It seems ridiculous in this age of climate change that anybody would want to promote a technology that uses more energy when other technologies are boasting about how much less they are using.
