Almost, but same concept. It looks to be taking advantage of the temperature of space (or at least as much as you can on the ground) as it does have a cover that blocks heat transfer to/from the wind. Its basically using a standard thermopile/seebeck module or basically a peltier module that is optimized for generating power, rather than moving heat, to generate power from the temperature difference.
