/challenges-projects/design-challenges/energy-harvesting/b/blog/posts/a-side-step-to-other-technologies-for-harvestingWhen looking around for energy harvesting solutions I found quite a bunch of intersting techniques to get motion into energy. A lot of these are highly experimental, but look promising for the future. I&#39;ll highlight the things I found most interestinen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/energy-harvesting/b/blog/posts/a-side-step-to-other-technologies-for-harvestingWed, 24 Apr 2013 19:35:11 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:514082de-da98-4def-bc2f-05842dd465faDAB1<p>Hi Victor,</p><p>&nbsp;</p><p>Very interesting find.</p><p>I think I understand how this magnetic generator works and I have to admit, it&#39;s a cool way to generator power.</p><p>Aluminum is a conductor, so inducing an electric current using the magnets make sense.</p><p>As the wheel turns, you will get a varying magnetic field from the aluminum, which you can then pickup with a simple coil.</p><p>You then just run the alternating current into a step up transformer, rectify it and you have usable DC if you need it, thought a simple diode would probably get you a good enough pulsed AC voltage to run the LED.</p><p>&nbsp;</p><p>Really a brilliant discovery.</p><p>&nbsp;</p><p>Just my opinion,</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=15673&AppID=106&AppType=Weblog&ContentType=0" width="1" height="1">
