Not a bad technology, but I'm not sure about the 99+% efficiency. Heat pipe recovery systems do have one drawback--they only recover sensible heat. Active and Passive Dessicant systems, heat wheels, can recover both sensible and latent heat and can work in both the summer and winter.
The efficiencey clearly can only be for sensible heat. For HVAC applications, its nowhere near 99% total. And even a dessicant wheel can only give you like 80% or so.
