this is a re-hash of my other post named 'Passive Solar
Energy Harvester'.
the device consists of a flat glass panel, under the glass is
a black background. in between the glass and background
is a network of transparent glass tubes containing a
magnetic colloidal suspension, also convieniently
black in
colour.
during the day time this panel heats up and causes the
fluid to circulate into a cooler inductor panel. the inductor
panel consists of a dense network of copper induction
wire. on one side of the copper induction layer is a layer
that lets the magnetic fluid flow over the coils. on the
other side of the induction panel is a magnetic layer made
from the stuff those flexible fridge magnets are made
from (to force the colloidal magnets to align their
polarities). the net result is electrical current in usable
amounts (depending on the size of the panels).

how does the panel "heat up and cause the fluid to circulate into a cooler inductor panel" ? [+] |
|

Sounds very expensive. I imagine it would take a long time to pay for itself. I think my idea for a better solar panel would've generated an equivalent amount of energy and cost less to produce, given that it requires fewer parts and less advanced engineering. |

Consider this: a moving conductor basically generates voltage in a magnetic field. Do you need a magnetic fluid or just conductive fluid for your idea? Either way, I think the difficulty would be to make it efficient, or even more important: how to generate enough voltage to be useful, since it's like having one turn of conductor. |

Perhaps a simpler incarnation of this idea would be to use a simple solar panel to cause convection and pipe the flowing fluid through a turbine. The turbine might be used to pump fresh water or generate small amounts of electricity (e.g. for a radio). |

If this heat driven magnetic flux was used to back a
normal photo-voltaic cell then the gap energy might
be made less. Any method to help the environment
of the junctions has to be good. |

This relies on a heat difference that is simply implied - but what would keep the cool side cool? |
|
| |
there is simply no "cold side" to cause a heat pump especially when you are circulating hot "magnetic colloidal solution" well known to get even hotter when forced past magnets. Where is the heat sink, the air? How is this better than a simple steam engine? It isn't. |
