I too lazy to click on links... wat does it do and how does it work?Originally posted by Simontay78:
A suggestion would be to have a manual kickstart, just to get the wheel moving, and then the generator is designed in a way so as to utilize magnetic force and momentum so as to keep the "wheel" spinning.. Maybe there will be resistance I dunoe.. not really a science student.. ^^Originally posted by Simontay78:So sorry for not speaking into the mic as I wish to use action to speak for it self ^_^
Description : Using magnet to repel the magnet to rotate the wheel.
Aim: A better way to generate electricity then a hand crank dynamo
If can be automated then it's one of the most efficient energy "conversion" generator.
Not complete hence still not perfect yet. haha
I fail to see how it can be a much more efficient. The main reason is because energy cannot be converted or destroyed. The only more efficient point is that there might be slightly less friction involved in the design as compared to the hand crank. However, the main generator is still the roughly the same, and experiencing almost same amount of friction.Originally posted by Simontay78:So sorry for not speaking into the mic as I wish to use action to speak for it self ^_^

i think u meant created.Originally posted by eagle:I fail to see how it can be a much more efficient. The main reason is because energy cannot be converted or destroyed. ...
yup, my mistakeOriginally posted by airgrinder:i think u meant created.
Ans: Nope, it's not using perpetual motion but uses magnetic, gravity with inertia and currently also include my small hand movement.Originally posted by deathbait:I can't be certain.
But are you claiming to have made a perpetual motion machine?
Thanks for your questions! For your question about generating a consistent and reliable voltage is however true, it's just like solar panels that have efficiency of 15% now subjected to weather conditions similarly to windmills.Originally posted by eagle:I fail to see how it can be a much more efficient.

[/quote]I am not using a dynamo to generate the electricity, find out how new type of non-contact generator used by windmills. I am planning a magnetic induction on coils to generate electricity, the magnets don't need to touch the coils hence not much resistance compared to normal hand cranked dynamo.
(I will demo this fact later once I test it out on my ideas haha...need time and my next pay to be in first haha)
And also what I am converting (not creating) are (magnetic + gravity + inertia) to become kinetic energy (wheel rotation movement) and using the kinetic energy to covert to electricity (inducing coils with the magnets). [quote]
In addition, from your video, it seems that with the magnet, you did not manage to turn the generator smoothly and continuously, which makes me wonder if the generator can actually generate a consistent and reliable voltage source to power any electronics
P.S. I'm asking these questions in anticipation that similar questions will be asked of you when you present your work. Good for preparation![]()
Congrats! Give me one if possible.Originally posted by Simontay78:Thanks for your questions! For your question about generating a consistent and reliable voltage is however true, it's just like solar panels that have efficiency of 15% now subjected to weather conditions similarly to windmills.
The common solution (by windmills) to solve this problem is a charge controller or bridge rectifier or Schottky diode to limit back-flow of electricity back to the coils from the battery. (Not tested yet so not sure correct or not, do correct me if I am wrong)
Once the battery is charged, the output will be much more consistent then normal and can use "inverter" to change the DC 12 Volts to AC 230 Volts at desired Wattage (depending on the inverter specification for power values)
I used a power inverter for 1000W hence can possibly run laptops and charge hand phones for a fully charged lead acid battery.
Do check out the video featured in my solar LED project on how to use the inverter to power a Television using a fully charged lead acid battery (big ones).![]()
What I would think is that it would be kinetic (hand) to magnetic to kinetic (wheel) to electric energy. Gravity and inertia are not really considered forms of energyOriginally posted by Simontay78:I am not using a dynamo to generate the electricity, find out how new type of non-contact generator used by windmills.

One possible method, which I'm working out for my FYP too, is to design a circuit (capacitor + inductor + power electronics) to store the gained energy into the capacitor (if you cannot make it consistent like a normal generator).Originally posted by Simontay78:Thanks for your questions!

Good point!Originally posted by eagle:One possible method, which I'm working out for my FYP too, is to design a circuit (capacitor + inductor + power electronics) to store the gained energy into the capacitor (if you cannot make it consistent like a normal generator).
my FYP is more of converting vibrational kinetic energy to electrical energy using a MEMs device. The goal is in 15 years time, they will be able to port such a device over to things like pacemakers, such that the pacemakers may be able to run forever without being taken out every 5 years for battery replacementOriginally posted by Simontay78:Good point!
That is one key component too, capacitor is to regulate and stabilize the output!
Hey, you are doing this for Final Year Project? Maybe we can have win win exchange in knowledge and ideas. I have to confess I had lost much of my learnings back to the lecturers since I graduate almost a decade ago! haha.
Now at 29 years old reaching 30...my knowledge is rusty at best. I am just doing my part to enhance the future of Singapore and the world if possible. Creating jobs.
Maybe we can keep in contact. email me at [email protected] and we can chat later
