generation of electricity through compressed air

**hotshot** · 22nd February 2009 01:54 PM

Hey guys i have came up with n idea of electricity generation through compressed air.

Principle-with help of some pressure pads the air produced at d output will be stored in a cylinder which will be compressed with d help of a piston,pushing it backwards.the piston will be released as soon as d air reaches to d desired pressure level set by us .As a result of which d air will flow out frm d outlet of cylinder at very high pressure...this output is then given to a turbine/dynamo which will convert it into electricity..

Q-will it be pssbl to genrt good amt of electricity??????

Please don't use 'txt speak', type your words properly.

You can, of course, use compressed air to feed a generator - air tools used in garages use air to give rotary motion, it's a common practice.

But where's the compressed air coming from?, you're simply taking energy and storing it in the form of compressed air - why not just use the energy to directly turn the generator?.

You can. THe problem is you need to find a natural source of compressed air. Because if you make your own compressed air that takes energy (and because nothing is 100% efficient it takes more energy to make the compessed air that you can store in it). ANd then you run it through your generator which again is not 100% efficient so you lose more energy.

You might as well just take the energy source that was used to produce the compressed air and use it directly. More efficient, cheaper, and easier.

It would be similar to plugging in a light bulb into the wall and using the light bulb to power a solar panel to run something else. You might as well use the power from the wall directly.

It's actually impossible to convert all the energy in compressed air to power because the exhaust always has some energy left in it. The higher the pressure the compressed air is the more efficient it will be.

The main problem with compressed air energy storage is Charles's law, the temperature increases when you compress the gas.

And you lose that energy.

The air will be pumped (in) through some pressure pads,this will be placed on the floors of buildings,malls etc...where the pressure on the pads will be exerted by people....

And do you imagine you can create large quantities of high pressure air using a method like that?.

i am reminded of a film. where the people who were rowing a boat will be whipped for their slackness
here also perhaps the pressure built up depends on the effectiveness of people pressing the pads. and you want to get back to medieval times and use whip on these pad operators??

please study the fundamentals of energy theory and the energy transfer mechanisms and their relative efficiencies.

will it be possible to generate good amount of air pressure using the air produced by human pressure????????????????

**duffy** · 27th February 2009 03:43 PM

Ugh, what you are proposing would be like making people walk across a sand dune. Gets very fatiguing.

**hotshot** · 27th February 2009 03:57 PM

it's nt like tht,we can implement it in speed breaker also......
we are just using the pressure created by humans on the pressure pads as input...or else automobiles in case of speed breaker.

Can any one help us in having the calculations done....??????(how much pressure rqrd,max pressure to be created in cylinder to produce compressed air..etc.

)

It's a silly idea, use an alternator connected to a bicycle to generate electricity.

**Mikebits** · 28th February 2009 11:02 AM

It would be one way to affect the population explosion as everyone started dying from cardiac arrest... Anyone seen Soylent Green, the bike powered generator?

i dont have proper idea about what will happen in reality
and what u can judge from the conditions in my idea?
ok according to u what is the alternative method to create high pressure?

hello friend

a bicycle alternator, can generate only 12 v. with the help of which we can just light 5-10 leds or power a small circuit

but it wont be an energy generating method?
