The
Boast Buster
5 foot diameter
Rotational Start and run at 2.7 Mph.
How the Boast Buster got its name.
(The comments on this page are
simply my opinion based on what I have seen, read, and heard.)
Over the last couple of years I received several
notes from my customers telling me to look at this ad and that ad on
Ebay, and see this website and that one because someone was saying
this and that about my rotors, yada yada yada, I think you get the
picture.
I normally just ignore people bagging on my product while trying to
make theirs sound better, but enough is enough!
Don't get me
wrong I think it is great that the competition feels it must degrade
the products that TLG Windpower is producing in order to make theirs
sound better. That tells me I must be doing something right.
My normal course of action when reading these comments was to
think of the words on a T-Shirt that I had bought a while back.
But now that the renewable energy market is starting to
boom we once again have everybody and their dog in their garage
making wind generators, blades, mounts, etc.
It is like
the 1980's all over again, everybody is an expert. All
this is well and good after all it is the American dream. But the
American dream can be pursued without punching innocent bystanders
in the nose.
Until now I had not offered any rebuttal for what has been said I
just smiled and thought of my T-shirt.
Just so you all
know the Boast Buster was originally going to be named the Tri-Nado
Express.
There are a few different reasons for the name
change so I will break it up into a couple of sections. No certain
one carries
any more weight than the other.
Part of the reason is due to a recent ebay ad
where a person was selling the black carbon fiber sets. The ad
claimed that only thin tipped blades can break the magic 1500 rpm
barrier.
What 1500 rpm barrier? (wanna
read my T-shirt?)
The Boast Buster turns
close to 2800 rpm top end and it has 2 1/2 inch wide tips that don't
flop around.
It also talks about how the blades can be bent and will snap right
back, and if Aluminum bends it will stay that way and cause the
rotor to be off balance. yada yada yada...
Are they mentioning this as a feature since you can tell from a
good distance if the wind is blowing by the noise coming from those flexible tips?
After reading all this hoopla I figured maybe it was time
to get that set of carbon fiber blade off my shelf that had been
sent to me a long time ago from a customers that replaced them with
one of my rotors.
To make a fair comparison I ran both the black
carbon fiber blades and the Boast Buster on the new TLG generator
head on the test truck.

test truck / mobile wind tunnel.
With no
load the black carbon fiber blades would not even turn my generator
head until the wind got over 14 mph.
The
Boast Buster starts turning the TLG head at 5 mph.
It took wind over 20 mph before the black carbon fiber blades had enough
torque to produce over 1 amp
into a 12 volt battery.
The Boast Buster produces 1 amp of output in half the wind the black
carbon fiber blades needed. (10 mph)
In winds above 20 mph the Boast Buster produces closer to 20 amps of output.
If you browse Ebay I am sure you have seen these ads
for
the 5 foot black carbon fiber blades.
I cannot give you an Ebay ID for the seller because it seems the ID
changes fairly often. That has never made sense to me for
someone that claims to have sold several thousand sets. I
would want to keep using the same ID on Ebay so I would have a huge
feedback rating.
These ads boast that the blades are
"engineering perfection" (Now
is a good time to read my T-shirt again) and about how fast they turn,
telling you that speed is where its at and cupped metal blades or
thin Aluminum blades can't produce the speed you need to make power. (yep
my shirt comes to mind again)
And that they have power that can not be stopped. (Oh
geezzz by all means read my T-shirt and if you own a set of these enjoy
a good laugh!)
My question to that comment is; at
what wind speed is that power reached? Is that right before
the roof of your house comes off?
However there is honesty in those ads.
They really
are fast blades (on a ball bearing shaft with no load).
The
truth of the matter is the black carbon fiber blades run almost
twice as fast as the Boast Buster can on a ball bearing shaft.
But what I have not seen is this unstoppable power they
boasted about.
It goes back to what I have been saying all along
"speed without horsepower is like putting perfume on a
pig".
I will say this, you can buy the black carbon fiber
blades for about 40 bucks and up, and the Boast Buster will cost
you 230 bucks.
As with anything you get what you pay
for.
If pictures say a thousand words see for yourself.

on the Boast Buster.
You can see those thin tips curling in the sun. ;)
Side by side the two lay, you can really see those flexible
tips.
Which rotor do you think can produce unstoppable power?
This picture was sent to me by a Hornet owner.
I think that picture probably said enough about those blades.
Moving on to the next rotor that boasts to be
better than Aluminum blades.
Another reason for the Boast Buster name is the ad
on Ebay that was ran on the 5 foot high quality Douglas Fur blades (which
you should know is a fancy word for a Pine tree) I got a
bunch of email when that one aired and found they too had made a
bunch of (see my T-shirt comments). ;)
Dean Brooke from
Florida, (also known as Ebay ID "ferocement") being the experimenter he is bought a set of them.
After a couple of hours running them he boxed them up and sent them
to me asking what do I think can be done with these to
make them safe to use. He said he was afraid they would come
apart because in a mild breeze they
were rattling his 100 foot long chain link fence.
My opinion at a first glance is this; the only way
to get any safe use out of this set up is to use them in a
fireplace.
The hub is very cheezy, and it is not even on a 120 degree pattern so it could
never balance!
This design uses a piece of water pipe with slits cut in it to slide over a 5/8"
shaft and tightens down with a hose clamp in my opinion is just plain dangerous.
It is setups like this that gives us harsh ordinances against wind generators
and with a hub like this we really can't blame any city council for not wanting a wind generators flying in the city.
In my opinion whoever made this hub cannot have much experience with
the forces
of wind. This blade set will not be ran on my test
truck because I do not want to risk my truck being destroyed when this hub disintegrates
and throws the blades.
In guessing I would say it would last a few seconds
in winds of 40 plus. But I would not want to be anywhere near
once the wind got over 25 mph. And that may be giving entirely
too much trust in what little hub is there.
(Added 5-10-05 from Dean: the
blades busted my stainless steal mount from all the vibration.)
See for yourself.

The almost assembled rotor with the front cover sitting on the
screws so you get an idea of how it would look.
The pine tree blades lay in front of the Boast Buster for
comparison.
The hub is numbered so you can tell which blade goes where.
If it were precise there would be no need for numbers.
The blades are screwed onto the hub with Deck Screws.
(DANGEROUS)
The wooden hub has a piece of water pipe screwed in the back of
it.
(VERY DANGEROUS)
The water pipe is split to allow it to slide over a 5/8"
shaft.
Notice the Hose Clamp that is supposed to secure the rotor to the
shaft!
(EXTREMELY DANGEROUS)
I want to apologize if this page has offended
anyone, I personally feel this is unprofessional on my part, but
like I said enough is enough!
I have every confidence in the people that have enough gumption,
desire, and skills to build a generator themselves that they can figure what
will work and not work on their own.
On the other hand I am only human and I am tired of being punched in
the nose when I haven't said a word about anyone's product (until
now).
Please remember I didn't start this. But I did think it would
be fun to share my opinion and T-shirt with all of you.
