Energy Transformation

It is simply that we use silicon and rely on light to nock out electrons that we can the harvest. It is a very inefficient process because it it an entirely random series of events. Nature dictates how fast this happens and as solar panels lose the efficiency as temperature increases, there is a limit imposed by the suns enery and the heating providing a self limiting effect. New materials such as germamium silicon mixes and galium arsenide silicon are makig progress, but they still have this basic limit due to heating.

The question arises when I want to get 12 volts using no a transformer, because the size and weith, but need only 1 or 2 watts galvanicaly isolated. That is the reason I was thinking in ligth.

Thanks

In your case today tech is switching mode supply with an transformer as lite as 1/2 oz. Cellular telephone charger is an good example.

Hello, if you only need a small power out put then solar will do 250mA at 12-18V is no real problem. The problems of cost versus out put come about when you want more than 2-5 Amps at 48-60 volts. So it can be increased via an inverter then the losses and cost realy become an issue.

We needed to do this at one of my jobs for a couple of watts.

What we tried with good results,

was to use a pair of DC motors connected by an insultaing shaft of the needed isolation length.

One motor is run by your power supply.

It turns the other motor to be a generator.

If the motors are identical, and the load isnt too great,

the output voltage will be a large fraction of the input.

You can either boost the input a little, or

choose motors with different windings to compensate for the loss.

Your efficiency will be way better than the 10 - 20% light approach.

You are right and the same problem exists with many fuels too. We know that better is possible and the is and has been a main pusuit of science and inventors around the world. Once it is accomplished it will be engineering and not science that applies the technology. We must remember that science is in the front seat of the bus and not engineering. The relative disciplines are best whrn they resign themselves in large degree to what they do best. Engineers are 20% Scientists and Scientists are 40% Engineers. In the pursuit of better energy we must comliment each other while an inventor creates the break through we all missed because we expected everything to fall within our own paradigms or conventionalities.

Thanks guys:

I am gratefuly to all of you for your ideas, all are posible solutions, the question is also the price together with the size and weith, i am shure we will found a way in the future, perhaps something on tunnelization, a chemical Approch, an organical procedure or something in the unified field theory.
