Peltier Generating More Watts Than A Solar Panel

[Tacmatricx]

Hi billmehess,

In your test, you have a source (peltiers) connected to your ammeter (load).

In this you are measuring both voltage and current.

When you add a peltier in parallel nothing changes.

When you add a peltier in series you see a jump in both current and voltage.

The reason this changes is that the resistance of the load... the ohms of resistance provided by the ammeter is constant.

An ammeter has an internal resistance and is acting as your load.

Using the formula V=IR changed to solve current I=V/R

By adding voltage (peltiers in series) and maintaining the same resistance both current and voltage appear to rise. This doesn't mean that the math works out this way as well... The peltiers have a limit of how much voltage and current they can produce in a certain environment. You can either increase voltage by wiring them in series, increase current by wiring them in parallel or do both by taking four peltiers wired in series and attaching another 4 peltiers in parallel... Do not ever mismatch the strings tho... by taking four peltiers wired in series and adding a string of three or five peltiers (also in series) and then attaching them in parallel to the four. series / parallel strings must always be balanced.

That was a great response!

What do you think of a Peltier effect if you had big enough plates outside in -40 C and + 20 C inside the house already using oil, gas, electricity...etc to heat our homes? 

Could the Peltier effect regenerate wasted power through lost heat?

Kind Regards,

Or for people in warmer climates...Could a Peltier effect if you had big enough plates outside in +40 C and + 20 C inside the house using no oil be of benefit to offset CO2 emissions?  Using Air Condition as in a house buried below the ground to conserve coolness while exchanging a potential with the above ground heat.

Hi Paul,

I think you'd be better off using a stirling engine at the moment, some of them can run off the heat differential between your hand and room temperature! Plus you can build them yourself instead of buying them with a fixed lifetime.

If you use a parabolic system to heat water, you can run the engine off the difference between hot water and cold water both day and night with the right insulation. Covering a large area with half cut polished oil drums (parabolic cookers) focused on a copper water pipe leading back to an insulated underground storage tank. All you need then is a solar panel driving the pump to circulate the water through the system when the sun strong enough to power the solar panel. Works out to be a hell of allot cheaper than covering the same area with peltiers or solar panels. Now you have a source of really hot water, oil, or coolant to drive your stirling engines pretty much 24/7 charging battery banks.

Change out all your AC lighting and appliances to 12V / 24V or 48V DC units and you don't even need to go buy expensive inverters either.

Hi Tacmatricx

What about a Sterling engine using -40C to +20C in cold climates, is it feasible using either the outside air to inside air difference?  Could a Sterling engine deliver enough power to heat one's house and keep the a Sterling engine system in motion and keep heating the house?
