thats true, but a turbine spinning even at 1750 rpm is a very dangerous thing. RPM would be a function of blade diameter, my 60" diam at 250 rpm makes me want to stay far away from it. It was designed to operate in the 60-120 rpm zone.

It would work of course, the question is how much usable output you would get. Also need a way to overdrive it to reach the rpms it states, pulleys I would guess. lot of work but may be a fun little project. I have an old dremel motor I will probably play with for the same reason, fun and a bit...

the proximity of the roof is causing turbulence. I have the same issues, and a taller mast is in its future. Placement should not be near any buildings, Mine is between two barns, so I use the funnel effect of the wind between the buildings to spin it, but that only works for winds coming from...

I do hate the race against the clock on those things. On the crypto exchanges, 2FA is used multiple times during a transaction, and the response time is like 30 seconds, so it becomes very frantic trying to put the numbers in correctly before the timer runs out after waiting to even get it. Its...

I was trying for 20 panels, I think it was about 50@ so maybe 1k worth, shipping was 2k alone. Yes, across the country I know, (and they didnt have any in the Atlanta facility), so I managed to get 6 used 185w panels for 50@ , but they were 3 hours away, closest I could find. Used panels not...

There should be charts available for wind generators, showing Voltage, current, wind speed, rpm all against each other. I had to develop my own as I made my own generator, but some manufacturers may post them, others just tell you (and advertise) "1000w generator" when this is likely the...

I tried to deal with SanTan twice now, good prices for reasonable equipment, but when I got to the shipping costs, I stroked out. three to four times the cost of all the panels to ship them.

Depends entirely on how the motor itself is wired. I wired mine for reaching charging voltage (14.5v) at a low rpm (60), but poles, windings, etc. all contribute to the end result. I suspect that 500 rpm is where the common motors are wired for, ie a car alternator really doesnt start putting...

Well, just an update for now. We have had a good windy month and I have come to a few conclusions. My startup speed is to high, needs to be closer to 5 mph instead of 7.5 mph. I can raise the height or increase the blade size to help that. Furling is not fully functioning, While my tail is...

My old Better N Bens leftover from the 70's fuel crisis is finally getting some rest. Now I just fire it up to to the spring rain dampness out.

I have one like that, and it does work well, although controls are limited by the app, but it does what I need. It will still need to connect to a router of some type for remote applications.

I started with 12v, and upgraded to 24v since al I needed to do was add two more AGM batteries. Easier on the wallet than going 48v with a single battery, as I have read 12v in series is not a great idea for 48v use. Small 2k system though, if I expand then I will consider selling everything and...

Suppose I wanted to measure current coming from the wind generator, (I already have a shunt on the negative side to measure use), how would one wire that? Would it be the same as wiring on the negative side except reversing negative black for red positive?

OP is talking about something like this - As far as a "Tesla Magnetic wheel" I didnt find much of anything except what we know of as an F&P motor, or an opposed circle of magnets on two wheels pulling towards each other. No demos on that device. Nor do I think Tesla ever cared much for magnets...

Yup - got that, overnight delivery I think. Had to tie the turbine off for that one. Did do some minor testing around the outskirts of it though. Had some decent wind on weekends but nothing really where I need it (15-20 mph sustained), although March isn't over yet. The weather station and...

I am using something like this - cheap, but working fine. https://windandsolar.com/digital-440-amp-charge-controller-divert-relay/ I know there are 12v and 24 v versions. I run the dump into two 300w resistors. I programmed it to dump at 14.7v due to interference from my PowMr solar mppt...

My chickens dont bother with flies or moskitos, or anything flying other than a butterfly sometimes. They are true decimators of dirt though. Having access to fresh ground they will start digging, and in a day can produce a chicken sized hole (with an accompanying dirt pile) , so your rotating...

Gov's have already done that to the atmosphere using the HAARP facilities, pumping megawatts into the air.

loads fine for me - no warnings (Brave on Win 8).

Watch a few of Wills videos, under "DIY Solar Videos" tab at the top.

Well, a bit of a follow up. Still tied up caring for mom, but I did start getting things in place. I set up a personal weather station directly in front of the turbine, about 6ft away (just enough for the tail to miss it) and at the same height. I also installed a security camera that will...

75w is about the draw on my current system, which handles that quite well up to 3 days. I have about 2kw of panels and 9600wh of batteries (4 X 200ah, AGM) using a 24v system. I run 3 chest freezers, and since they run intermittently, 75w is the average reading.

I run 300ft round trip at only 80v - I put a meter at the panels and at the inverter and have about a 2v drop with 10g wire, no issues at all.

I did the same for the hookup in the barn, cheapest I found was a PowMr unit, $92 on amazon. Works okay, not a fan of the display, I would rather see volts/amps going into batterys instead of volts/watts, but I can press the function button 3 times and get that.

Thanks for those stats. Hopefully I may be able to get back to this project this weekend, but my 92 yr old mom is in the hospital and we have been taking care of things there, not sure when I get get enough time right now. I will Update this thread as things return to a "more normal" situation.

quick update - i did get the two extra dump load resistors in, and started a set of tests last weekend (which appeared promising even) and the wind was cooperating as well, but real life got in the way for now, so had to stop for now, but hopefully will continue soon as things should even out...

I feel your pain, I hate those "squeezeit" connections, I just shut down my house system to check all the screws for tightness, which I do every 6 months or so, and invariably find one or two that can be tightened more. I havent seen any controllers with ring connectors, but certainly would be...

Second resistor is wired in series with the first one now, but wind has died down, so I guess a 2 ohm preload on it at this point. I will wire in a 4000 w water heater element as a dumpload tomorrow. update - I purchased a 7.5w nightlight filament bulb and a 20w filament bulb to test as well...

I ordered another 2 resistors. will look for some 20w incandescent bulbs, or maybe something low wattage I can screw in there. I can add the other resistor tonite or tomorrow by jumping it into the circuit.

I see, I had it backwards. I understand the resistance is blocking the current and the turbine will spin up. So a "cool" filament allows current flow and a "hot" one restricts it. Odd that it started and spun up with the bulb (21 ohms-cool) but wont spin up with the resistor (1 ohm). I guess...

So the hot resistance may not be a bad thing under certain circumstances. At high rpm and high voltage output (75+v) it may heat the filament and "throttle" the incoming amps, but i imagine at lower "normal" voltage (say 25-45v) it would likely "cool" back down and ohms would decrease allowing...

Appears to have made it not want to start. I could put the other resistor in series this weekend, wind is supposed to cooperate. I read up on Ohms so I could understand what we are doing, it seems I can use the bulbs to find the sweet spot of balance between the ohms and the amps coming through...

High wind warnings out for tonite. If they roll in within the next few hours I will go out there and see whats going on, if not I will have to tie up and lock it facing east-notheast. Strong winds are supposed to be coming from the SE. Good news if the winds are staying high through Monday, so I...

Brought to mind an article I wrote for a website many years ago - NatGeo - Doomsday Preppers Series Episode Air Date: 4/03/12 Topic(s): Concerns were as follows: Dirty Bomb fallout, Conventional nuclear attack, CME and EMP Prepper #3 This last person in this episode is Jack from...

I dont know if it was charging, just saw it spin from the house in a pretty light breeze, didnt stay up as the breeze was variable. In the wind last night it was stalling, spinning slowly at times then stopping. Didnt measure the wind speed but clearly was >15 mph and fairly steady. Wind was not...
