Yup I have looked for the existing designs. Basically we have tried to run it with an alternator but its rather hard to pedal while generating electricity with alternator as compared to generator (we have one small generator but we got it as a scrap so no idea how to manufacture another one)...

Basically I want to generate electricity by bicycle pedaling. So far what I am aware of is human can pedal with 50-60 rpm, so in my design we have this conversion ratio of 1:30, accounting efficiency decrement with number of transmission system, Around 1500 rpm can be produce at max with my...

Hi, I want to generate electricity at 1000rpm aprox. and than to charge a 12.4 volt battery. So that i can use battery whenever i want. What could be suitable way?

And also does alternator only give AC output?

Hi there, Money is not an issue, I tried to find out generator which works at around 100rpm and 12-14 volts output but couldn't get it. So the remaining option is to have an assembly.

Agreed! but as u'll find in some of the developing country getting electricity supply is actually a problem. There it is more useful rather considering economic stuff.

So for mechanism having rpm around 1000, what is better to use alternator or generator? P.S.: i am considering generating power only. As for the alternator we need to give some starting voltage by connecting it to a battery. While for a generator it doesn't need starting voltage. And again is...

yeah i know what convolution ... but i don't get when it comes to phrase convolution annd deconvolution of phase diagrams... i heard this term but didnt get what it says...

Can anyone explain how the convolution and deconvolution of phase diagrams are described?

So now the different case but similar to this one : if there is a hole such that cylinder can just fit into that, so the situation is like lower and the upper part of the cylinder is in the air while middle part is surrounded by water ... now u can measure whether buoyancy is acting or not...

so in that case thrs no upward force?

isnt thr ne macroscopic way of explaining this same phenomena as in the terms of forces acting on the cylinder?

so what are the limitations for the buoyancy force theory?

but in this case if u look how the cylinder is placed there is no water contact at the bottom of the cylinder as it is attached to the bottom of the tank, so no force(as in terms of pressure) form the bottom side ... so the only pressure from water is only on the circumferential face of the...

Hi all, If i attach a cylinder at the bottom of the water tank such that some of its part is out out of water. So in this case what would be the buoyancy force acting on the cylinder? -agtee.
