PART 1 WIND POWER PROGRAMS - RPM AT MPH.wmv

Thanks!

[muddymuddymuddmann]

@Theskidmark61 THANK YOU FOR MAKING USE OF IT. THIS VIDEO HAS A LOT LESS VIEWS THAN I FIGURED IT SHOULD. IT IS A MUST HAVE CALCULATION IN ANY WIND TURBINE DESIGNERS HANDS.

HOPE YOU GET IT RUNNING OR JUST USE THE ON SCREEN EXAMPLES WITH A LITTLE MORE MATH TO GET THE CALCULATIONS YOU NEED.

TOGETHER WITH THE OTHER PROGRAM , A LOT CAN BE PLANED OUT.

Also how feasible is it to generate 240V at 1.6 amps, 400w, using wind?

This is what greenhouses use per light and it isnt to far from what a street light uses, thats energy we should definitely recover from the environment.

[muddymuddymuddmann]

If you are in a country where they use 240 volts as a househould voltage, then the ceiling fans there will do around 240 and about half the rating of the rated output.  Go for it Mr Santos, Im chearing and i will be glad to see another one up in the air.

Happy new year

Im really interested in how this program would be different for a vertical axis wind turbine? Would it be much harder to write the program and which variables would change the most?

Also want to say that i found your page through greenpowerscience and its nice to see that you've uploaded videos this week because greenpowerscience was inactive for about a year.

Im sure when you have time it will be loads of fun experimenting with VAWTS.

[muddymuddymuddmann]

very good comment Mr. Santos,

Vawts are to big to get the same power out. and they have to be geared up in most cases because of thier low rotational speed. they are great for low winds and lower speed wind though. but there is little power in the slower winds. Vawts are mostly drag machines and dont get much faster than the wind. for the program to do vawts there are many variables like angles and frictional gearing losses. Check out Ed Lenz, He has the most impressive Vawts ive seen.

Missouri wind and Solar.  Think they were only $159. Order three more so I can run w/9 blades.

[muddymuddymuddmann]

sure as soon as Ed Mc Mahon sends me my check. LOL Thanks for the post and link.

Point well taken. 45mph is a good furling speed. Some of those cheap turbine furl too soon after they start to make power. Try some carbons mudd. You'll like em.

[muddymuddymuddmann]

OK HAPPY BIRTHDAY TO MEEE. Nov 29 , that makes me 49 years ancient. thanks !!!!!

lol Anyway how much did you pay for yours? and where did you order them.

[NCHiker1970]

292.5mph! Ouch duck because that could really hurt! Good advice though! Thanks for posting! Even at low speeds the RPM's are high, very surprising!

[muddymuddymuddmann]

Ya It's a safety meeting in the making.

Hey Muddy Very cool program thanks for the info bro.... Terry

[muddymuddymuddmann]

Its something I wanted to share for a while. the best thing is first you find your average wind speed for your area. then figure out what kind of power you need. then figure out from that info, what size prop needed. then you will know what rpms you are dealing with. and with that knowledge you design you alternator. then you need a program to figure drag from the wind to find out what kind of strength your tower will need to be. and never under engineer any thing having to do with the wind.

Hey muddy - looks like an old QBasic program to me? Man am I aging myself or what?

[muddymuddymuddmann]

Thank GOD I am not alone!!!! actually gwbasic is right on the money. by the way I just turned 49 on Nov. 29th. 1961 boomer lol.

Don't you think furling is a way to miss out on free power? (small turbines only-under 6' dia.) Carbon fiber blades. 2000 r's. No problem. They've seen 90Mph more than once and done fine. JMO Great program. Thanx MUDD

[muddymuddymuddmann]

Good point but if the wind makes it run at high RPMs there are a lot of potential problems that crop up. and dangers. centrifugal force turns broken props into rocketing torpedoes. the carbon fiber blades are remarkable though. but bearings heat up. i figure that furling at 35 MPH or 45 is good enough. and they will still put out good power at full furl. if your battery voltage is exceeded by too much without a switching mechanism, its bad on batteries and dump loads.

wish i had carbon blades!
