Topic: Alternative Electricity for Mining - page 12. (Read 28142 times)

I want to ask and i already said that an extractor of air that consumes 150 watts has 1750rpm. How is that different from consuming 500 watts instead of 150 watts? As I see what we need is 1750 rpm right to give air blowing speed of 47mph?

also to convert rpm to mph, https://sciencing.com/convert-rpm-mph-calculator-2854.html


Using that webpage to calculate it, it gave me the number of 20 mph, 1750 x 60 =105.000, divide by 5280 = 19.88 mph.

Maybe your 500 watts 1750rpm is not 1750rpm, more like 4200rpm. That explains why it uses 500 watts. 3 x 150w = 450 watts.

The noise a 4200rpm generates kill everything in few meters.

Also what i think is the most important is the cfm and the cfm is related to diameter and rpm.

Generating electricity from wasting electricity, i wonder is that is really viable or just a waste of time.

The wind turbine works better with? 30cm, 40cm, 50cm, 60cm, 70cm exhaustor? and I guess it has to be very close or with a good connection with pipes, cause it can not have any leaks.

Thats because you are stupid or playing stupid then because it has been stated how it is done.

You are not applying 500w you are using 500w to turn the motor which in return is creating the rotational speed of 1750 rpm.

So i am applying 500w of rotational speed that is then converted to the equivelent of 47 mph wind with a pulley

The 47mph simulated wind speed is then turning the GENERATOR which from 47mph speed produces 2000 watts of power
now I am using the 2000w to energize the batteries which in return powers the inverter.

Which again converts the 2000w into usable ac. 24vdc @2200 watts with a battery bank of 8x 150ah gives you 1166 amps which when converted to ac 220 gives you 127a of useable ac @220v

SO the only power you need is to keep the battery bank charged 2000w of charging power is 83 amps as long as you dont go over using the 83 amp charging power you are fine if you do your batteries discharge at a slow rate eventually stopping at the charge input power. If you need more power you add a second generator head to the mix and now have 166 amps charging power and so on.

YOU clearly do not understand this process or how a charging and inverter system works when a battery is involved.

A grade school kid can understand this process and how it works so come on some of you are grown adults and you are arguing it cant happen.

Or a mental asylum.


What do you think your pulleys/gears/whatevers do? They balance speed and torque, you don't magically get more power at the other end.

sounds cool.. BUT before spending thousands, I'm going to try this on a SMALL scale..

using this cool little generator and some pulleys..

hydro seems the way to go if you have a river...

24 volts at 2000 watts is approx 83 amps output

1750 motor rpm at 1:4.5 ratio will get you 7875 rpm which gives you a surface speed of 4123.3 fpm when you convert 4123.3 fpm you get a rotational speed of 46.8556818 mph which is enough speed to run the generator head at full output. So a 9 inch pulley on motor and 2 inch on generator is the only thing to configure for the simulated wind speed. If you use different pulleys then you need to make sure you stay at or above the same fpm travel on the belt surface speed

atleast you comprehend if you look at the chart in the link you posted you will see in the picture the wind speed to power conversion now convert that wind speed to rpm and you will know at what rpm the generator will need to spin at to get the desired output wattage at its rated voltage you will need approximately 47 mph wind speed to produce 2000 watts convert 47 mph to rpm and use an electric motor with a pulley drive ratio to achieve that rpm for example a motor with 1725 rpm at 1 to 3 would result in 5175 rpm

If you need things look at missouri wind and solar they have a nice variety and reasonable prices. Golf cart batts work great   they take a good beating

This site is good for configuring the pulley system

I see this.

900 rpms  to charge at 48v  and is rated for 2800 watts the electric 1/4 hp motor does 1750 rpms

I just so happen to have a 48v golf cart next to 4 mining rigs running on a 230v PDU consuming 13.3 amps (~3000 watts)..  would be pretty easy to test this..

Planning on adding solar / wind eventually so will use components for that..




maybe there's too much resistance added though when there is a LOAD on these things.. .

I caught your wife trollin sent her on her way though something smelt a little fishy.

and now you've proven you're trolling.

that's all folks! glad no one else will be stupid enough to try this.

Fine you win put the blades on it and then use your leaf blower to blow some air on it and now you have your full wind system with 150mph wind. Now your only cost is to run your leaf blower unless you can keep blowing so much air yourself

you don't seem to know a lot of things....

1W = 1J/s. it's literally energy per second.

next you'll tell us that you didn't know wind had energy. 

I didnt know the wind contained watts. I did know it uses energy in the form of movement and in a tornado the wind can be circular until it runs out of energy. But never knew it contained watts.

are you serious obviously you are clueless its the rpm of the generator that produces the output power where the f*** do you you get 2000 watts of wind power.

you can't replace 2000w of wind power with 500w of electric power and expect the same output.

i'm still not seeing any proof provided here. i wonder why?

Apparently you are that stupid or just cant read correctly because this is the same thing as a off-grid system with a motor turning the generator instead of wind so yes it costs you a few dollars to turn the thing but that cost is much less.

This is my thread so why dont you just get the hell out of here you have been nothing but a rude asshole from your first post.

your missing the point if you want to run this free then put a prop on your wind turbine it then becomes free this system is replacing the prop with an electric motor to reduce the power cost not to make it free instead of driving the wind generator with wind you are driving it with an electric motor

there's exactly 0 people running their house like this. how are they living off the grid when this whole setup requires grid power? you don't think too well do ya?

put up or shut up. show pics or video of this exact setup powering a house and providing more power than they are putting into it, without wind or solar to supplement it.

i am not chipless i am only stating a fact you must be the nasa rocket scientist no wonder the space shuttle blew up..
this setup does and will work.....
