hmm, with nothing rotating it is quite difficult to get something close to those things. Was my thought to not convert the vertical motion into a rotary motion a mistake?

Here is the completed prototype: https://goo.gl/photos/GRXcLuVXU9Z4d3yC9 The tape on the sticks is to prevent it to much amplitude.

(https://goo.gl/photos/41hpgzJJS5FAV1VV6) This the construction. There is a floatation platform made out of cork with 4 sticks on it that move up and down along with the waves. I have created 4 coils that hover above the sticks. The magnets are placed on top of sticks inside the coils. The coils...

My first attempt was to measure the open circuit voltage. When measuring across the LED i measure the same values. Anywhere between 0 and 200 mV.

i calculated the amps first by doing: V(induced)/Resistance of wire: 0,94 / 9,67E-003 resulting in 476 amps... then V*I = 0,94*476=450 watts. I did not sound realistic, but what makes the difference between applying these formulas and the actual result?

I thought about that. From what i found online the resistance of thinner wire would reduce the the output too. And i thought it would be less work making turns with thicker wire. Which was in fact quite heavy work to make a nice coil. I could not manage multiple layers with this thickness.

Based on all this, and good weather conditions, i tested again. It appears that my multi-meter takes almost a second to take a good reading. I tested this on a battery and it show two to three reading prior to actually indicated 1,5V. That is way to long to measure my wave generator, as the...

Yep, it is very clear why the LED won't light. I did study that article and decided to base the expected output on Faraday's law (http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html) as the energy generation comes from magnetic flux. Using the formula: -windings *...

Thanks Anurlunda, My device works on water wave in a canal next to my house. The wave height is between 0 and and 10 centimeters (during storm). The period of the typical wave is 1 second, with a wave height of 1 centimeter. So all very limited, but fun. The device uses 1,21 T magnets in 7mm...

Hi all, Thanks for reading this. I am physics enthousiast and currently trying out some new things like wave and wind energy. Building some prototypes and having a lot of fun while doing so. Hope you can me out with the challenges i come across and that i can return the favor. Thanks, DC.

How can I calculate the capacitor needed for my wave energy collector? I have have build a wave energy collector. It consists of multiple coils in series with magnets moving up and down, following the waves underneath the unit. My multi-meter measures anywhere between 60 and 250 milli volts...
