😎👍

Darius Rotors have been known for thousands of years, and are not anywhere near efficient as plain face-bladed devices. I have at least ten engineering books about this. A good example is the old fashioned Steamer on the Mississippi (which has a horizontal Darius rotor) as against a bladed propellor, and this test was done back in the 1800's by competing river shipping companies. Also for the Darius's the blade angles cannot be altered easily as they are for a hub-controlled rotor. As such they cannot ever be efficient at all speeds. The airplane people figured this out at about 1901 or so. All modern propellors use multi-angled blades. Darius's have also been made this way, but the mechanism is about 20-times heavier and more complex, due to the double angle and gravity problems.

Thank you for making an introduction to the product!😊

One problem. Everything must heat up together and dangerous for lithium at high temps and reduces lifespan of battery.

Compact charger

Just to note, batteries don't have the kind of resistance you say. They have internal resistance, this is why they can get warm when charging and discharging, but as the size of the battery goes up, the current required to notice the resistance drops (assuming parallel, series is different calculation but same idea, more watts needed to see effects of resistance). The resistance batteries have is like putting a resistor or old light-bulb in series with each cell, the higher the charge or discharge current, the more the resistance is noticed and the more waste heat you generate from it. However, batteries have a self discharge and the charge controllers may not actually let trickle charge currents enter the battery bank to begin with. So in that case, the turbine does charge your battery bank, just not as fast as the cells are self discharging, however, they would self discharge slower since some of the lost power is being replaced by the wind turbine. Generally any time current flows into the cells, they charge, even a little, and when current flows the normal direction, they discharge, at least a little. So the size of the battery is not a concern, the battery is charging, just too slowly to be measured... and the bigger the battery, often the higher the parasitic self-discharge current since the self discharge is a few % per unit time, that percentage of a small bank is an average of a few milliamp, but a bigger battery bank has the same percentage rate per month that it loses which is like losing say 1 amp constant... the actual numbers depend on battery chemistry, design, age, damage, temperature, state of charge (sometimes), any leakage through chargers that are idle or powered down (MOSFETS are not quite perfectly off when off), etc. So in your example, the turbine basically just slowed the discharge of the cells because it generated less than they lose sitting idle anyhow. It did not fail to charge, it was just that the parasitic loads consumed all the turbine's energy and then some, so the turbine just made is to less of the battery energy was lost since it made up some of the difference. Good analogy is with water tanks, batteries are like tanks with a leak, some faster and some slower, the more tanks the bigger the battery bank and the more water is lost. Even a tiny trickle of water WILL raise the level in the tanks... but not as fast as the water is leaving... so the effect is that the net loss is lower. Like the turbine, it would be charging the batteries, just not very fast, so slowly that the battery is still losing power to self-discharge (like a leak), say you are losing an average of 2 amps and the turbine puts out an average of 1 amp, the turbine DOES charge the batteries, but its too slow to be making headway, so what it's doing is effectively slowing down the discharge of the battery by making up on average half of the lost energy. In this hypothetical, 2 of them would maintain that battery and charge it as fast as it tries to discharge itself. Basically charging and discharging are opposite chemical reactions. One turns the battery into lead, lead oxide, and acid, while consuming electricity, the other generates electricity while turning the battery into lead sulfate, lead sulfate (2 plates, both lead sulfate), and water... assuming lead acid, NiMH and Lithium ion variants are different, more complex reactions, but same idea. Lead acid cells will spontaneously convert back to discharged state (think of it like if there was a tiny LED connected to the cell at all times, or as if electricity flows slowly back though the acid). So if you put in enough energy to react 1 gram of battery and make it into acid and lead, ready to rock, but in that time the battery concerted 2 grams back into lead sulfate and water, you still lose 1 gram since 2-1=1, but you DID charge 1 gram of material, its just that a phantom load that you cannot see or remove that is part of the cells themselves has drained more than you put in. But the turbine or slow charger did help you, see if you had not had them hooked up, you would STILL lose 2 grams of battery, but not have recouped 1 gram, so you would lose 2 grams because 2-0=2 Oversimplification but that is how things work.

many thanks

What size Battery was that in the start if the vid?

Here's a video showing the difference between switching AC and DC at higher voltages. kzbin.info/www/bejne/o4LTq6qIbNx_m9E

I saw a guy guy test one of these pretty VAWT's close to that one. he only got 5 Watts from it.

Similar to the old expensive Maritime Sailboat Rutland. But they state this on Spec so it's ok. I Recall your channel 15+ years ago when I was also into these. Good to hear the True results TY.

In my mind, a small hawt generator would be useful to make up for losses in the inverter/batteries. A 500-watt model will yield 50 watts on average, which is close to the standby average with the inverter on and heated batteries.

or may be i should say wider

wood bigger blades make moor power?

Either a longer chain, or a lower hookup........it's planing............Z

How many watts does it use ? How much on Amazon if you know ? Thanks Kyle

Well , you're on the roll with these electric gadgets...😊 Maybe next one will be Tesla sybertruck , or something...Good to see you back on the channel. 😊

So the updated price on these is 169.00 and I've seen these on sale for .99 bucks. Cheers😊

I like to mig Weld, but I like Arc Welding better , Nice to see you Back !

How long to charge a solar generator?

So how many watts is in 10 amps?

You don’t need clamps for a bailer hitch

You don’t need clamps for a bailer hitch

The Airx are good, but only make 0.5 Amps max in good winds.

I recall you from years ago when I was in this field. Many sub 500 Buck models make just 10- 20% of their claimed output.VAWT comes around every couple of years. They look great visually but are inherently way worse than any HAWT.

you need to make a power controller for the rota that turns power off till it spins then by time turns up the charge current to the rota . the energizing current will put magnet load on the unit making it hard to turn . so you need a set of transistors from a battery that will regulate the rota supply . This will help immensely if you use a car alternator ..The thing is to build the system on the floor with a thick metal frame so the horse power can be gained by using a large surface area such as a split 45 gallon barrel split into as the blades . speed will be less but tork would be far higher . ... So just build one for the ground and add all the energy together ..

I like the SHARP CYCLOTURBINE

How can I add a wind turbine to my house electrical system to supplement my solar system?

so your title is bullshit

Liam F1 by Archimedes?

So modern home wind generators actually produce enough power to make them financially viable? I've read that for the large commercial windmills, the manufacturing/setup costs, combined with maintenance/parts replacement costs are greater than the value of power generated over the lifetime of the windmill. Government subsidies are needed to make them profitable. If the smaller home system is a net positive regarding costs, what is the approximate net profit over the lifetime of the generator? If the generator system costs $5,000 over it's lifetime, but produces only $5,100 worth of electricity, it probably wouldn't be worth the effort. Have you been using wind generators long enough to show that they are a worthwhile investment?

I have an off grid shed I need to heat. Only need to keep it at 40 degrees. I was thinking an aluminum can thermal panel w solar fan. And a backup propane heater if needed. I can’t run power so need an off grid option that isn’t expensive.

How much are you guys saving on power cost. Also anyway I could wire the battery bank right to my furnace and one for my ac unit?

What can I use on my narrowboat top speed is 4 mph

I have been researching and following wind turbines since 2000. I agree with what you are saying about cheap wind turbines, but I believe you are leaving out several great implementations of VAWTs. You mentioned laminar air flow - a VAWT doesn't care about the direction of the wind hitting it. When you switch to HAWTs, you have to put some king of airfoil rudder on the back to keep it aimed into the wind. The key parts of a turbine are the rotor design and the electric generator connected to it. These need to be made of quality, durable parts with efficiency and strength for the blades, low friction, a stable drivetrain axle, and strong mount for the generator. I didn't hear you mention the Dutch manufacturer of Tulip turbines or the U.S. manufacturer Flower Turbines. These VAWTs do not risk hitting birds, they have more blade surface area proportional to their size compared with the size of the 3-blade HAWTs on towers. Additionally, the higher efficiency of VAWTs compared to turbines of a similar class allows them to produce electricity at lower wind speeds, and the "clustering effect " when installing them close together actually improves their efficiency.

Ügyes vagy,van alap ismereted!Newton méter a lényeg!

Forget getting a vawt. They only produce 25% power compared to hawt. There is not that much wind at low altitudes.

this one of the few creators that shoved realy easy yo make bolts even if you have no powertools

or build a plane from old bike frames . or timber ..two by four frame or ...some way simpler construction just crude wood and plyplates as wings , in a strong simple way l guess not glue then ,maybe just test strenght of timbers by weight test in middle see if cracks , .. would it work for a few flies at least , fun vid for youtube safer to remote control with man weight sandbag in seat. or old plane wings on old car drive till lifts no propeller.h

Build one with a transmission

Very constructive; many thanks

Interested in wind generator but also considering something for well pump either generator or one thst uses wind to manually pump ... but issues would be winter us when its needed. On grid for electricity but want to be more off grid and lose power 3 weeks a year or more

I am not doubting you, but if you have no experience with vertical wind generation, you did not mention any experience, how you discount them all? I was looking for talk about that, you started the video off with that, but you don't say why they are bad, ect. Not the most helpful :(

Nice project. Don’t forget to install a ground to the heater and to your disconnect ( metal box). If they were to become energized ( shorted) somehow your fuses wouldn’t trip because the current isn’t going anywhere, it will just put voltage on the metal parts. Your gas pipe should also be grounded already, so a short wire down to the gas pipe will do the trick. I don’t have much experience with solar but I am an electrician, and grounding metal parts in almost all scenarios is crucial.

From all my friends in the wind industry: If it is vertical axis it is junk, and nothing more than kinetic art. Second, don't do wind unless your average ANNUAL windspeed is MEASURED and is in excess of 12 mph. Third, only use tried and proven horizontal access wind machines which are a minimum of 30 feet taller than anything within a radius of 300 feet. The taller the tower the greater the power.

Hi. What happened with your Ista Breeze? Is still working?

Good info thanks!

A VAWT is actually good at the laminar flow, but, that particular model is also a badly designed blade. Not poorly designed, badly. It was done intentionally.

1.5kWh solar panels on roof of my RV produce 4-7kWh daily. Flat-mounted, six, 250watt panels. I have a 9.3kWh solar panel solution on my home roof. On average, it produces 30-50kWh per DAY. It was not cheap but I qualified for the tax credit (30% toward the system price). Turbines for home solar just don't make sense in urban setting unless they are on a leading edge of a commercial roof.

Very great work. Errors come from best projects, it is normal. Truss is much more expensive, but it is the better solution. In these videos, I don't see any electrical grounding.
