Default Generators that use Wind power.

I will be reading the comments in this newsgroup for the next few days and
learning from those that are positive and helpful.

I know that this is an out of topic posting to this newsgroup. That is a
reason that I am posting here. I want to learn from people that are not in
the business of cogenerating energy. I want to read in this newsgroup
valuable comments from a fresh perspective. By off topic posting to random
newsgroups, herein I may gain an honest response.

There are definition links for you to read. There is physics data, and NASA
data that is referenced. I would like your honest opinion. I would like to
read logical responses. Childish screaming about commercial posting or out
of topic posting to this newsgroup will not slow my quest to find logical
and valuable responses. Someone on this newsgroup will be able to think for
themselves and will give me an honest and logical response that I may learn
from and potentially use. I look forward to your opinion.

Topic: WIND POWERED GENERATORS.

I would like to introduce you to a new wind powered generator company.

These are specifically for LOW wind speeds. These are affordable sized for
the average (non-city) U.S. homeowner.

This is a very small company. These are being built one at a time.

The page is at ReasonablePower.com

http://www.reasonablepower.com

Please take the time to look at the page.

If you have a valuable response whereby I may learn and do better as I build
this company, please post your response to this newsgroup. I will be reading
postings herein for a while.

Thank you.


Put more info on your website. Windmill size and price is not enough to
go on. How much power will be generated at various windspeeds? What is
included in your price?

Torque? Even though the "lift" of wind turbine blades may be low, most
blades on commercial units are 90 feet long or so. So, if you were just
producing 1 pound of lift at the tip only (not true since the blade
produces lift along the entire length), you would have 90 ft./pounds of
torque at the hub per blade, no? So commercial 3 bladed turbines would
produce 270 ft/pounds of torque at the hub (90 per blade). What is the
value of your "lift" produced out 6 feet (on your 12' diameter model, 15
blades)? If I calculate correctly, each blade would need to generate 3
pounds of "lift" at the tip to get 18 ft/pounds of torque per blade for
a total of 270 ft/pounds to match the wind turbine. How much wind would
be needed to lift a 3 pound weight at the tip of your blade? To me,
torque is torque. You can generate the same amount of torque with a lot
of force over a short distance or a little force over a long distance.

Work (Watts) is what's important here. How much work can your units
produce (in Watts)?
