Blast of cold air

cold air anybody?

We use a small solar panel, to drive a pump.  And we compressed air - but you then heats up a commentary absolute pressure.  It is Celsius plus 273 degrees.

So every double the pressure on the air we heat it up by over 250° C.  We then need a body of water.  A large lake or sea is ideal.  A suitably size river can also be used.

So we double the heat to the air.  And pump the pressurised air and for polyurethane cylinder.  When we vent the air it cools down, we will produce a blast of air is -170° C.  The turning is a bit severe.

So recommending mixing it with a blast of ordinary air at 40° C.  So regair years cold blast at 10° C.  That in the heat of a sunny day is very welcome!

And because the energy is supplied for free by the sun it is effectively free!  Or to pay for the small solar panel.  And a 20 UK pounds!

And this idea does not produce a blast of moist air - just regular chilled air.
