I’m looking for a cheap and simple set up to make a thermopile to create some electricity.

The idea includes to have the cool end of the thermopile in cold water and the hot end heated by a magnifying glass focusing sun’s light on it.
Then the electricity generated could be used to charge up some rechargable batteries maybe…

I haven’t really done much physics since I left highschool so feel free to correct me if you see any flaws in my set up.

not very efficient but yes it can work.
Key is there must be dissimilar metals at each junction as well as a delta temp at each successive junction
the engineering problem is:
need to maximize temp difference
but heat conductivity brings them to same temp so cooling has to be continuous and efficient, which costs more energy than you can produce
low resistance needed to avoid waste energy as heat in metal circuit. Low resistance (ohm) usually goes with low heat resistance so delta T is low.

Good for a demonstration
Was proposed once as cheap add on to lamps in third world where cost is everything.

Military uses thermo generator with Pu radioactive source for deep space, far from solar power. No body wants to launch Plutonium systems in case of a launch failure.

Iron-Copper series works I think, easy to try.

I think the thermodynamic efficiency limit, delta T over T cool, in absolute applies. ( am not sure) small temp differences at high lowest temp for cooling is a basic limitation for practical use.

Might work with very high temp solar mirror systems but value of electric power is far too low vs capital cost.

A generator uses a coil that has 370 turns and a 0.59-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil is made.

Given:
N = 350 t, B = 0.59 T, f = 60 Hz, emf = 120 V

The induced voltage is given by:

V = 4.44Nfφ = 4.44NfBA = 4.44(370)(60)0.59(L²) = 120

The length of the square-shaped winding is:

L = √{120/(4.44*370*60*0.59) = 0.045 m

In this video I demonstrate the magnetic interactions of the MOSTAT (moving stator) magnet when used in conjunction with the rotor magnet arrangement shown in video #4. This is a very powerful concept, and this demonstration should make it quite clear that this can be used to perform useful work.

I have been researching EV cars and conversions and am wondering about using a generator instead of batteries. I am not an enviro-nut concerned about making an emission free vehicle, just one that is cheap to drive. It seems to me that using a generator to power the motor, although it would use gas, would be way more efficient than a normal gas engine that is in a car, and would be lighter than batteries. Also, if it is a diesel generator I could run bio-diesel to cut back on emissions. Am I correct in this assumption?

i have considered the same thing. it will take a good size generator to power an ev tho. say you have a 15hp motor in your conversion. you will need a 15hp generator minimum to power it and it must have a large enough surge rating to handle the start up currents. one hp equals 746 watts. all in all the idea is sound but a little more involved than it seems.

A generator can be made using the component of Earth’s magnetic field that is parallel to Earth’s surface. A 162-turn square wire coil with an area of 4.41 10-2 m2 is mounted on a shaft so that the cross-sectional area of the coil is perpendicular to the ground. The shaft then rotates with a frequency of 18.0 Hz. The horizontal component of Earth’s magnetic field at the location of the loop is 5.00 10-5 T. Calculate the maximum emf induced in the coil by Earth’s magnetic field.

No, but if money doesn’t grow on trees, why do banks have branches?

Another FREE LOADER (see the last question) idea is to generate power as follows: Water on top of the Gulf of Mexico is quite warm, but deep down the water is cold. The plan is to heat some gas with warm water from the top so it will expand, and then cool the gas with water from the bottom so it will contract. The gas is alternately expanded and contracted so it drives a piston back and forth. The moving piston is attached by conventional means to an electric generator to make electricity.

a) This idea might be made to work.

b) This idea could never work.
The answer is: a. Offhand this sounds like the (former question) FREE LOADER idea, but there is one vital difference. It does not just take heat from the warm top of the sea. It also provides a cool place to dump the heat. This idea does not force heat to go from a warm place to a hot place, rather it allows heat to go from a warm place to a cool place. it is the temperature difference between the top and bottom of the sea that makes the conversion of heat energy into work possible.

There is presently serious interest in this concept. A commercial demonstration of the Ocean Thermal Energy Convesion (OTEC) concept has already occurred. There are several proposed power unit designs presently under consideration. Remo provides one of several excellent links to learn more about this emerging technology.

a. This idea might work. And my understanding is that it is being considered in some areas where the surface water is warm and the bottom water is cold.

This violates neither the law of conservation of energy, nor the laws of thermodyanmics. Under the laws of thermodynamics, you can derive energy so long as you have a temperature differential, which you do here. The thermo efficiency might be low (my recollection is that the maximum efficiency is based on the ratio of the temperatures between hot and cold), but if it works, it works.

As a matter of fact, you could place a thermocouple in the water and use the temperature differential to drive it with no problem.

But this raises the additional question of why is there a temperature differential. This is because the earth is a dynamic system. It is continually receiving solar energy and radiating heat away. Its poles are colder than the equator. There is wind. This sets up ocean currents which are both vertical and horizontal.

The colder polar surface waters sink and spread out across the ocean bottom. Without going into to much detail, the result is that for most of the planet, the bottom waters are colder than the surface water. This means that there is a thermodynamic potential to drive a heat engine.

Which fossil fuels are used for generating electricity and heating our homes?

How can we tell which homes have loft insulation?

For an uninsulated house, which part would you insulate first and why?

Which method of insulation would you choose?

Explain how double glazing works.

How do some houses absorb free energy from the Sun?

How do houses keep in the heat it has absorbed?

looks like a project from college to me, why not look it up on wikipedia

I liked the web site. A shunt DC generator is the classic machine for producing DC current. The operator has a lot of control over the generator voltage just by controlling the field. In automobiles regulators control the voltage and current automatically. The field current can be modulated as necessary until the iron of the field saturates.
