Short Case Jacobs Wind Plant, 1.8 Kw output, 40 volts DC.

 Client of mine has one, he's thinking of selling it, as he's a bit
short of cash.

 Now, I took it down off its latest tower, had it reconditioned at
client cost (re-wound, re-dipped, megged, new bearings, new brushes)
and it's good to go.
 It *DOES* need new blades, which I, or anybody, can get for about
650USD at Michigan Wind for a balanced used set, 1500USD for new.
 The stub tower needs to have the pickup box rebuilt, and a new LOWER
bearing on the swivel post, both of which I will be acting on in the
near future.
 It CAN come with a 60 foot square pyramid lattice tower (14' on a
side at the bottom, I seem to remember) that I did have "laid down"
but the client has not as yet dissasembled for transport.

 I've seen similar gennys listed in the ads in the back of Homepower
for 10 000 USD and more. In its current state, my client has told me
he would consider offers in the 8000USD, or 9500CAN range (and yes, I
*know* that doesn't match, but as I say, client's numbers ;-).

 Anyone with interest, please contact me at this email address:

dj_macintyre@hotmail.com .

 Canadian buyers could have transportation and re-installation added
to the base price within, say, two to four hour's drive of the
National Capital Region, in either Quebec or Ontario.

 My apologies if this breaches the canons of the group, but I could
not find an "alt.energy.forsale", and only posted to the two groups
that seemed applicable.

Hi guys,

I have no idea what the price should be for a 1.8kW generator,
but I am thinking: How much PV power could I get for this price?
And how much real estate would the panels use?

(I could research this myself of course, but I am lazy and will
assume somebody has the answer).

Approx. 3 dollars a watt for just the panels.  Estimate 2.5 kW worth, would
be 25 square meters.

 New, a whisper 175 3kw unit sells for $995, pv would run $2,000 for 3kw.
For a 1.8 kw, cut the costs in half.

A better comparison might be to hang two H80s, as they, like the
jakes, are designed for lower wind than the 175 is (and the jake is
set for an even lower top speed than the 175, 18mph compared to 24mph
for the 175). Also, the many issues regarding two blade versus three,
and the jake's top speed of 500rpm keeping it reasonably quiet and,
from a maintenance point of view, longer lasting ;-).

 It also seems to be a matter of taste; in many articles in Homepower
magazine (Mick "I was so impressed, I bought the company" Sagrillo et
al ;-), the Jakes seem to be the benchmark by which all others are
measured, due to their rugged construction, simple centripital gear
flyball feathering and braking system, lack of electronics... but
absolutely. Anyone considering laying down that much money on a
windmill is best councilled to look into the matter very closely, to
make the generator matches their need, not the other way around!
