         [0042]    In another example the installation depicted with  FIG. 8  is top side view of a waste air flow capture system installation  1000  with an HVAC compressor  1006 . In this instance the installation begins with removing  1008  the HVAC compressor&#39;s original exhaust fan shroud  1004  via bolts  1018  and removing and replacing  1010  exhaust fan  1002  via the original fan motor bracket  1020  by removing  1014  one or more fan blade bolts  1016  and the exhaust fan  1002  is replaced with the second fan blade assembly  400  disclosed herein. In some embodiments, wherein the waste air flow capture system further comprises that an HVAC compressor&#39;s or heat pump compressor&#39;s original fan shroud is removed. Next, as depicted waste air flow capture system  100  is then mounted on the waste air flow channel  1012  of the HVAC compressor with bolts  102  engaged are aligned with cylindrical shroud mounting apertures  124  and support arm mounting apertures  104  and tightened within threaded compressor apertures  1022 . Moreover, the waste air flow capture system  100  may be installed in series over multiple waste air flow channels  1012 . In some installations, the original compressor&#39;s fan motor  1024  is removed  1026  and replaced with a replacement fan motor  1028  for greater efficiency operating with the second fan blade assembly  400 . The replacement fan motor  1028  may be an efficient ¼ hp electric motor rated between about 1100 rpm and 1725 rpm. The second fan blade assembly  400  is lighter and more efficient than the exhaust fan  1002  and therefore the original compressor&#39;s fan motor  1024  rated at about ½ hp to ¾ hp is no longer needed to efficiently rotate the second fan blade assembly  400 . This raises the efficiency by reducing the amount of power needed to rotate the second fan blade assembly  400 . Moreover, this also allows for an increase speed of the wasted air flow from the compressor, which results in more power being generated by the single generator or dual generator waste air flow capture system  500 .
