Old school vs. new school....

Sometimes tech can be too tech.

Why do I have a strange feeling that Choice B is a tad bit cheaper than Choice A?

Choice A:

The Sun Lizard Heat Extractor

It uses solar energy, natural air movements, and heating and cooling dynamics to harmoniously moderate the comfort of your home or building. It can be retrofitted into existing building or installed on buildings under construction.

Choice B:


Works by utilising the velocity energy of the wind to induce air flow by centrifugal action.
