Dear Mr Turgut. I might not know a lot of physics or other stuff, but math I know. A 30 degree road has a 50% slope. That means that if you drive 10 horizonta= l kilometers, you will find yourself 5kms higher.=A0 Since you said you dro= ve on the slope, than you should be around 4472 meters above sea level. You can break down the road in as much segments as you like, all with 50% s= lope. It will still have the same result.=20 If you would have said 30% slope instead of 30 degrees, that it would have = been a slightly different story, but still a suspicious claim.=A0 =A0=20 Now lets say that you drove 10 kilometers on a road with at most 30% slope,= and an average of 7% slope. This could be something true. Still I doubt th= at anywhere in the world there are roads build with 30% gradient. I don't say I don't believe your story. Just that the place where you ran y= our tests seems out of this world.=20 --- On Tue, 2/15/11, Yigit Turgut wrote: From: Yigit Turgut Subject: Re: [OT] Almost Free Energy (or not) To: "Microcontroller discussion list - Public."

Also that measurements are taken due to sea level, try=A0 using the other part of your brain instead the one trying to find weaknesses everywhere ((: --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
