The H2O alarm clock is not really all that amazing, the cool thing about this little gizmo is the battery.  It is powered by water.  When the battery runs out of juice, open it up and top it up with water straight from the tap.  Each filling is good for two to three months.

The clock has the normal features; time and date, alarm and it packs in a thermometer.  The water powered alarm clock falls short in the looks department, but does well in the environmental stakes.

Available for $19.99
