The disposable Medis "Palm Cell" product announcement reminds TreeHugger about questions that recently arose from our reporting on a "button battery"-sized micro-fuel cell discovery: revealing strong interest in whether disposable can be green. Like the Medis product described here, the button fuel cell also had a military market prospect, which no doubt creates a conficted view for some. Pragmatic TreeHuggers understand, however, that the free market can propagate a good design and help discard the others. The Army needs resource efficiency too. Letting them take the prototype step is fine if it gets into TreeHugger sights and we get to vote with our dollars.
