(upbeat music) [MAN]: To take it from some sort of drawings or something that
we have here and all done,
and then turn it into something real,
I mean that's it!
That's what it's all about.
And the students, you know,
they come here and they sit in class for years or whatever ---
they need to realize that too.
They need to realize that in the end,
it's about turning some idea into some sort of reality
and seeing it work
and seeing all the problems associated with making it work.
I think it's really kind of an eye-opener for them, so ...
It's good. It's great! That's really what it's all about.
[YOUNG MAN]: I think it's a big part of my education,
because, like I said, it's not something I'm gonna be able to learn in the classroom.
This is a very unique experience
that I'm very lucky to be able to participate in.
You know, I'm learning a lot about the design process,
the, you know, as well as all
the steps of good engineering design.
[MAN]: Today we're focusing on the
electrical end of the system
downstream of the turbine.
So the wind turbine generates electricity
and the kind of electricity it generates is not very well-regulated:
it changes in magnitude, it changes in frequency ---
it's not something you can really use.
So that involves a couple different components.
One of them is turning the essentially AC
frequency that's generated the wind turbine,
which, like I said, is not uniform and varies,
rectifying that into a DC type of voltage
and then passing that through an inverter, that then creates
something that can sync up to the grid.
So this is the generator that we have, sitting on top.
This is just a temporary structure so that we can do some mock up.
Essentially, we're mocking up the entire system here in the lab.
The generator, the rotor in the hub, all the electrical downstream.
So to kind of give you some idea,
this is a template for one of the blades.
So it would go on
something like this.
But this is just a wooden template.
We're actually having the blades made by a company in Schenectady.
And they should be ready within a month or so.
We're enclosing it with this duct that you see here on the floor,
which has been made by one of our alumni,
Thomas Baum, Class of '69,
and he produced this in his shop down in Little Falls, near Utica, New York.
So he's been working with us, which is really quite exciting.
So in conjunction with the whole electrical downstream aspect of it,
we have this, I guess you could say, more mechanical build phase
that we're working on here right now.
