Many people regret the fact that after installing the above rated turbine,
decided to upgrade within one year. The cost of this small system was
lost. The tower was not suitable for a larger turbine, the controller could
not be fitted either. Misc wiring, chargers, breakers etc where also too
small for the larger machine.

The cost of this new 10 KW turbine is not yet determined. When testing
is completed I will be posting all related info to DR1 website.

Thanks for your interest, talk to you soon.

I was recently in Germany and saw some very large tyrbines. One was being repaired and they had one blade laying on three (3) 13 meter trailer beds and it still extended. Have you any idea the output and physical dimensions of these things? I see them in groups of 30-40 all over Southern Germany

Hi there Argo,

The german turbines you saw in Germany range from 600KW to 1.5MW.
A typical 600KW turbine cost $1.2 Million canadian and it can power
approx 250 average homes using 36 km/hr wind. The tower is usually
80 meters high and the swept area is 2,500 sq mts.

This kind of turbines are designed to connect to the local grid, are
privately owned and operated by large private generation companies.

Regards, Georgios.

I own a home on the Northcoast with a flat concrete roof that faces the ocean. I have 20 to 40 km/hr winds almost every day in most seasons. I have an invertor that charges an 8-battery backup unit, but the power situation has been so bad lately that the batteries don't have time to recharge. It sounds as if your 1 kv unit would do the recharge job and your 10 kv unit would supplement my batteries when the power if off. What do you think the units will cost? Thanks.

I am currently looking into bringing to the local market a ground-breakingly priced new wind turbine in the 1-3KW range.

Realistically it will be at least a year and there are many ways for the project to fall apart along the way. I will keep you all informed.

It sounds like a condo complex or neighborhood of approx. 200 homes/apts with an upfront cost of 40-50 thousand could be " free " from the grid. And, thus, independent from the woes of power outages that plague the country. Certainly seems as though the costs would be easily recaptured over a short time frame. Is this so? Or am I missing something? John

Georgios, Put me on you're list of people that want to know more. When do you expect to have marketable results and pricing?

Hi from georgios,

My new designed wind turbine will "fire-up" the
whole house and some. It can be connected to
existing battery systems that many people have
right now in their homes/businesses.

Battery storage has some drawbacks;
1. Lifetime 3 years.
2. If charge drops below 20% risk of damaging cells.
3. Very low amperes stored.
4. Slow recharge time.
5. Expensive, old tech and heavy.

Others ways of storing kinetic energy is using air
compressor to dump loads instead of commercial
heaters. The stored compressed air can be used
during low or no wind days to power an air motor
coupled to a conventional generator, controlled
to power the house on demand(will not run if not
needed).

A large air vessel, buried into the ground, at 1550 psi
can power the house for 3-4 days depending on
consumption.

Furthermore, via electrolysis excess power produced
from the wind turbine can yield hydrogen. This gas
is the fuel of the future for autos, cooking and
heating. It burns just like propane with no emmisions.

Compressing air and hydrogen production as means
of storing energy are tested also by us, here in
Toronto. I think batteries are a thing of the past.

Solar panels can compliment the turbine(hybrid system). An array of 16 is propably a nice package.
Price wise, solar panels are costly with low production. This high cost is why not many people
have invested in them.

Have fun, see you.

Still, if I got it right, your solution is dedicated to serve private housholds ?! And what about similar solutions on a bigger scale, e.g. to serve SMEs ?! Again, if feasible at least a comparison in percentage regarding start up cost, life cycle cost such as maintenance and cost for disposal might be helpful ...

hi Benny,
Air storage vessel size to vary for small or larger applications.
Itemized see below cost.
1. Air motor 10 HP $600 US.
2. Standard 7.5 kw generator motor $985 US. (marathon motors USA).
3. Air vessel in metal or concrete underground by local labour
and materials approx $3000 US.
4. Air compressor two stage $1300 US.
5. Misc connections (wiring, air tubing, fittings etc.) $300 US.
TOTAL COST $6,185 US.

All the above components have, with proper maintenance, 10 years
lifetime or more. As a result the yearly cost is $618 US.

The performance of this storage arrangement is:
a. Complete stand alone home.
b. All electrical devices are powered 100%.
c. Power supply for 3-4 days depending on consumption.
d. More time to play, less to worry about battery charge levels.
e. Enviro friendly.
f. 100% reliable. The ice will never melt in the fridge.

I believe this air storage system may even cost less than batteries
on the long run. Your friends will love it as much as you when
you invite them for dinner. They would be very interested to
see how you have power all the time and they do not.

Hope you agree, talk to you again soon.

Hi Camden Tom,
Please read my response to Benny today, it may be of some
interest to you. Testing will take approx 6 months. Be sure, I will
post all results, details, pricing etc as the become available from
the engineers.Promise.
Thanks, Georgios.
