ABBA (not the Swedish band) has just released its CL-168, a water-powered calculator that does away with the need for batteries or fuel. It comes with an 8-digit display and an ergonomic design. I wonder, assuming water could be harnessed to light up the display, it would do much better than any solar-powered calculator to date. No idea on how much this costs though.
