I have built two cars eoliche with all the fundamental characteristics of the publication of PIGGOT, except the disks. These last ones are 30 cms of diameter and 3 mms. of steel thickness inox (what it is not magnetized).
I reach therefore the, the first car perfectly turns already, but despite the strong wind and a big number of turns you/he/she has never overcome the 15-18 v.
On the second that is identical I have proceeded to make some verifications to the bench with a battery to 24v and despite I did her/it very quickly turn (at the most of the manual strengths) arriving to a reading of 24v, the ammeter measured less than 1 Ampere. I have tried to also make some verifications with the other car with the same result. The doubt has risen me that probably the lack of power is to debit inox to the thin disks of steel (what it is not magnetized) that don't transport the flow. You thing thought of it?
Can you point out me some data you have performed to the hand bench it frees for being able to make a comparison? To me it seems very strange that don't succeed to overcome 1 Amper making to rotate to 200 - 250 turns the car.
I am now preparing me to find 4 disks in sweet steel to set above to the disks inox already resined with the magnets, but I don't know if however if that 3 mms. can of inox harm to the flow however.... Thing thought of it?
Thanks a lot of
