The longer the blades, the less RPM the wind will give you... this also depends on TSR (tip speed ratio).
I was under the impression that one would get more RPM than with shorter blades
With a 30km/h wind, for example, which turbine would preform best - the one with a 1.5m or the other with a 3m blade diameter (all other things being equal)?
Can you also explain what TSR is?
[quote="jessica22"]We are pleased to supply the magnet you needs. For wind energy, it is a hot topic and also a good solution to scarce resource. We are interested in it and have cooperated with some Germany company to provide the magnets and magnetic assembling they needed.
Windgat, is this chick talking about rare earth, or some other type of magnet? And did you ever took her up on her offer?
I`m probably going so sound incredibly stupid by asking this
, but here goes...
The magnets found behind car speakers, ect, is this what you guys call "rare earth" ?
Where does these magnets come from?
I`m not messing with you, it`s just that I am a complete novice when it comes to windpower and I`m learning from scratch.
