    <div class="moz-cite-prefix">   Looks like a technically nice
      approach - a solar heat collector using some (un-named) fluid with
      a low freezing point so freeze-up isn't a problem, operable either
      on straight solar heat gain or if insolation isn't enough to
      attain desired temperatures then kick in a compressor and operate
      as a heat-pump from the panel to storage.<br>
        I wish they'd say that in so many words.  The brochure wording
      has a shady character similar to many pseudo-science marketing
      scams.  Yes, Nicolas Carnot.  Heat pumps all, & most
      refrigerators, use the cycle named after him.<br>
        I'd ask for more specifications & performance test numbers
      and references.<br>
