Water-powered cellphones by 2010?

Way to go.  Engadget has an eye-catching note about Samsung and the possibility of a water-power cellphone from them by 2010.  That would really be interesting.  Any startups thinking on similar lines?  Let me know.  In the meantime, Samsung released their first HSUPA handset for the South Korea Telecom’s network with 2Mb/s upload and up to 7.2 Mb/s download.
