Renewable Energy Question? (Motor + Generator)

[Andy™]

DS is short for District Six where I live.

that will do

hopefully they dont have t'internet there

if you get him drunk, then no idea what he will come up with next. maybe something to do with solar panels aimed at the moon of a planet 300 light years away

Don't be silly.

Solar panels, driving a light bulb, to illuminate the panels, to generate electricity   :innocent

damn, why didnt i think of that?!

best go patent that idea before anyone else tries to

do you think a 1 candle power torch bulb will be enough to power the 4KW of solar panels on the roof?

Stick a reflector behind it and your 1 candle power gets magnified to 1 billion candle power.  Sorted.

read oldest posts I  not a electrical I can't help you with solar panels self ruining thing device  

 

[kasco]

I know how to change bulb if that will help you

You're missing a critical opportunity here guys. Transformers are 99% efficient, using Kasco's earlier formula, that means for every 1kVA you put in you get 1.99kVA out.

This time next year Rodders ................

Or even you could purchase a 12VDC to 230VC inverter, connect that to a battery charger, then charge the battery that powers the inverter.

Is that more on topic????

I must apologise for any upset, alarm or harassment caused, my few and far between posts I have written.

I understand Kasco's concept, but "too much to drink" is beyond me!

 

[Marvo]

I think i may have had too much to drink.....

The fact you say that just means you haven't had enough.

*Edit* The parsing of the bbcode quote tags just did something funky.

oh, its like that funny drawing of the water running uphill to get to the waterfall,

anybody got any links to a pic of that?

I could give you a link to a golden uphill waterfall........................but that just wouldn't be appropriate.

That's the trouble with the "theory" types they don't live in the real world! The world looks a marvellous place as a map then in reality you meet humans?suddenly It doesn't look so good ??

Just saying, not wishing to cause offence to any fellow beings.

Good evening.

 

[steptoe]

got it

 

[Sharpend]

Do they build them in flood risk areas only?

 

[steptoe]

it drives a water wheel that powers a generator powering a pump to pump the water back up the hill,

what you cant see in the picture is the 3&1/2 mile diameter pulley I had to make out of balsa wood and toilet roll tubes.

@op. I dreamed this very same idea up when I was about 10, ok not with quite as much detail your going into with different size pulleys etc, but even then it didnt take me long to realise it wouldn't work.

Theory good but, friction is your enermy, its going to absorb the energy,through bearings in generator and motor, between belt and pully, even between the moving parts and the bloody air around them, cables between gen and motor will have a resistance and this will be turned into heat. Even the sound it makes is using up your energy.

If it was that simple why wouldn't a belt with a pulley either end run and run? Pulley would drive belt, belt drives other pulley, this drives the belt and the. The next pulley, on and on

i guess that explains the national shortage of bog roll

do you know how much the loss of energy will be on motor , pulley , generator, and others ?  before post I calculate with 100%loss on motor real life is only 80%

50% loss on pulley real life is only 10%

100%loss on generator real life is  90%  

 

[steptoe]

chances it will ever work 0%
