Longer battery life definitely is an added advantage that makes a product sell. That's why researchers are coming out with new concepts to make technology more sophisticated like those of urine-powered batteries and other compact forms recently introduced. Medis Technologies too have churned out a disposable fuel cell to power mobile devices on the go.
Medis Technologies is using borohydride alkaline solutions inside its Fuel Cells, that gives you 30 hours of talk time or around 60 hours of music playback on an iPod, as per the claims, what else one wants. Placed under $20, will you ever mind to refuel it? No, never.
You can have these fuel cells in 2007.
