4.5 HOURS OF USEFUL SUN IN THE US!!! THATS IN ARIZONA AREA THE REST OF THE US IS BELOW THAT. OH AND WAHT ABOUT SATURATION OF THE MAGNETIC FIELD IN WHERE NO MORE CURRENT CAN BE CREATED!!! IT CAN SPIN AT 200 MPH BUT WILL PRODUCE NO MORE POWER!!!

Dear Futurist I have watched many of your videos about home renewable systems. From home roof turbines, vertical turbines and hydrogen solar anels I am very confused. I do need this renewable home system to power a 6 3bedroom block of flats I like the hydrogen solar panels but how cheap and effective is it for home power supply Please advice me. Cost and efficiency and availability are my considerations Thanks

That's a great recommendation! The Segway Portable PowerStation Cube Series sounds like a fantastic option for outdoor enthusiasts and RV lovers. With its massive capacity, fast recharging, and waterproof technology, it's definitely a reliable choice. Thanks for sharing the video and introducing us to this breakthrough product!

Depends surely where you live. Wind would be good where I live as it's alway windy. Suns not great in north east but wind is. Both would be good, as would batteries. Price rockets when you need folk to fit them and sign off. Look how many there are fitting solar now. Can't tell me these are all trained. One trained and twenty chancers

@@paulos9304 - Dig into the challenges of generating much power from wind. It's not just about it being "windy". Solar is still a better option in just about any residential situations.

Robert Murray Smith talks about this on his KZfaq channel. Wind power is excellent on a massive turbine on a wind farm out at sea. But hardly worth the effort as a micro turbine at your house. Especially when compared to the simplicity of solar panels and their lack of moving parts/maintenance requirements in a domestic setting

Cost per watt is one measure, but then there is the cost per watt when you want it. Here is when wind complements solar. In producing power when the sun is not shining, it reduces the depth of discharge. Few people have enough solar and back to last more than a day. One could double their solar and battery back up, but adding wind where it makes sense (windy areas), increases battery life by reducing depth of discharge and helps carry one over periods without sun. This is not to say wind is for everyone. I'm just saying cost per watt is not the only metric to weigh.

@@kreynolds1123 - The thing is, when you really dig deep and "do the math", it is cheaper to have the watts (in solar capacity) and watt-hours (in battery storage) than it is to implement enough wind generation (watts) to make financial sense OVER adding more solar and batteries. It's just a fact that small-scale wind turbines aren't a good option, fiscally speaking. Look into it...crunch the numbers yourself. This isn't "theory" we're talking about, but something easily quantified with a few simple equations. Solar and batteries is more cost-effective than small-scale wind.

Criminal prosecution? What was stated on a review that would lead to that.

Yeah but the EU are also upset about brussel sprouts not grown in Brussels being called brussel sprouts and champagne not made in Champagne, France being called champaign. There isn't always a valid reason behind EU objections.

@@johnwang9914 Right...and threatening unfavorable reviewers with prosecution for false content is even worse.

Yeah the noise clearly scares me

You made great points. And yes, there is a cost point where wind would never make sense. But I frequently see arguments that boil down to cost per watt. And that's important. More especially for grid connected hones that don't need to worry about power availability as much as off grid. But there is also a cost per watt when you want it metric that's subjective. Let's say one adds a battery to last them through a day and night if need be. But if the sun doesn't shine the next day, one is forced to adjust their power use or spend twice as much for battery to last two days, but they'll also need more solar capacity to ensure that one day of solar production covers a that day of one no solar day. You effectivly doubled your cost of your solar and battery install, for a level of surety that you only need occasionally. On the otherhand, a wind turbine tends to blow when the sun isn't shining (cloudy and rainy and at night), which lowers the depth of discharge of the batteries which prolongs their life, and will have a better chance of providing some power on those cloudy rany days and nights. Im not saying wind is for everyone, but depending on one's needs, there are cases where complementary wind does make sense to ensure access to power. But I get it, It's costly to insure against down time beyond 12 hours of no solar night and many will simply adjust their power consumption

@@kreynolds1123you are assuming though that there is sufficient wind to be meaningful. Most home installs of VWAT’s just don’t make economic sense. When I hear about how low their cut in speed is, I know their product isn’t suitable for home. The largest factor in wind generation is wind speed, which it’s potential is measured in wind speed cubed. So if it cuts in at 2.5 m/s it will produce almost nothing compared to fully operational speed to get max wattage at 12.5 m/s, say. It’s the difference between 16.5 and 1953 multiplied by the turbines efficiency and area swept. Regardless the turbine costs the same. Home wind turbines only make sense if you have access to really great wind, regularly. Most places just don’t have that. I am intrigued by the roof ridge design, as that has other things at play.

@@brettgracey9682 😁 I just wanted to point out I didn't make any assumptions about "does one have enough wind". I thought that "there are cases" implied circumstantial site conditions like is their enough wind to justify. But your right in that wind isn't enouhh for everyone. Despite decades of helping people with wind turbine making and generator making, where I live doesn't get enough wind to justify the expenses. And because of my latitude and my roof angle and azimuth works well in both sumer and winter, and no trees shading except very late evening, solar works best for me. And because I have grid power and my electricty suplier credits me 1 for 1, I don't have any need for battery backup. Reguardless. I acknowledge wind is not for every one, My main point is that there are some cases where wind can make a fine complementary energy source to solar.

@@kreynolds1123 yes there certainly are places where small wind is complimentary. It is a very different beast than large scale wind, most people don’t realize that. Like I said, if they advertise a low cut in speed, they are trying to trick you into buying. I live not far (1/2 km) from one of the Great Lakes. It almost always seems windy at my house, especially when it’s colder weather. I’m betting though if I took readings and created a wind bloom, I would find my backyard doesn’t have sufficient wind, versus solar. Since I know the math, I understand truly how niche micro wind applications are.

@@brettgracey9682 Too low cut in speed? Wouldn't a too high number, as well as the cut off speed, be more of an issue? A turbine that barely charges the battery at 2.5m/s is still better than one that won't move at all unless the wind is at least 5m/s. But the turbines also need to slow down if the wind gets too high to avoid burning out, so it's not that it needs 10m/s for optimal output that is important but whether a gust of 13 or 20 m/s will stop it from working for hours. One is rated as "strong breeze" and would happen often in windy areas, the other is a "gale", as in you need to secure for a storm. The roof ridge design is indeed interesting, but a number of people claim it would make horrible amount of noise. More data is needed.

I'm not doubting them but women seem to hear wind turbine noises many men don't and it drives them nuts. If you want freezer food fit one to your house

You're right! I had to take mine down because of the noise and the fact it did not get constant wind.

The clue might be in "decades ago" - turbine technology has evolved massively in more recent times.

@@headgirlblues No it has not! I´m in this industry

@@jonashammar8907 As you're "in this industry" (is that wind turbines, in particular?) are you not excited by the Powernest project or Aeromine? I'm not suggesting noise wasn't a problem, just that it was unresolvable.

Absolutely right. Since power output is proportional to the cube of the wind speed a very low starting speed essentially gains you nothing.

@@rogerphelps9939 True. That makes it even worse. From the data sheet 500W is at 12m/s, 300W for 9m/s. I in my ignorance was thinking of something like 50W at 2m/s. Which is physically impossible! Not to mention techniclly. Using P_wind = 1/2*ρ*A*v³ with ρ=1.225kg/m³ (density air), A=1.8m² (swept area as per data sheet) ,v=2m/s (my target wind speed) the maximum energy = 17.64W. With Betz Limit it is 10.41W *MAX*. Even though the intervall(?) between 2m/s and 4m/s makes up about 40% of all wind speeds in my area, that's only about 125kWh of additional energy a year. Wind speeds are roughly equally distributed in that intervall, I'll use 3m/s as an approximation. P_wind_total = 59.535W. P_wind_betz = 35.13W. 35.13W * 365d/a * 24h/d * 40% = 123,095Wh/a) TDLR: @Roger Phelps You are absolutly right. The starting speed of 2m/s does not help at all.

30 Years to see a return on this investment. In 30 years we will have Fusion plants.

Small wind turbines are absolute junk. It's hobby gear.

thats actually a pretty good idea! Im gonna make another video about 3 other promising Wind turbines fitting to supply a neighborhood community. stay tuned :)

Batteries have their limit and I am afraid we are almost reached it. So if it makes economical sense for you right away -- it is ok, but dont count on cheap batteries in the future.

@@heyhoe168 With the billions being put into the industry I don't think you could be more wrong. Sodium batteries are already going into mass production, once at scale I think a 50% drop pkwh in price can easily be achieved in a decade. Electrons don't weigh much so I think there is a lot of room for improvement.

@@jedics1 only time can tell. My assumtion is: batteries have big enough history and investments long before ecv histeria. So I expect some improvement but not the revolution.

@@jedics1 PS while electrons dont weight much, they in fact demand a lot of space and chemical energy is a tricky thing to capture and reuse.

@@heyhoe168 What do you mean by "demand a lot of space" ? Electrons are tiny, its the materials we use to store the electrons within that take up all the space was my understanding.

At windy mountains those turbines would really make sense 👍🏼👍🏼 Im currently working on a video to introduce other home wind turbines as well. Stay tuned 😁

But when the sun isn't shining, wind will outperform solar. It isn't a wind versus solar comparison, winds advantage is that it augments solar. If you are grid tied then solar has the advantage but if you are grid free, wind reduces your battery requirements.

@@johnwang9914 wind would augment the off grid system even more if the wind didn’t die at night. Wind speed and force typically go down in the evening, there may be exceptions but not here! Once again dollar for dollar that also includes maintaining the system.

@@919hammer Wind is actually more consistent at night. I was involved with building a supercomputer for the express purpose of weather modeling to find locations for wind turbines where power would be more likely to be generated when needed by the grid. Of course, a private individual doesn't have much choice to select an appropriate location but the very fact that some of the power is produced at night offsets the battery requirements of an off grid system. Naturally, the sporadic nature still means batteries are needed but in truth the wind does blow more at night.

I have 11 solar panels on my roof. Several have damage already and broken cells and burned up sections. The brand was Astro Energy installed in 2009. Solar can break down too. It does happen even with solar. I'm an electrician. Anything electrical can burn out. It all can break. Literally. My system was rated at 2500 Watts and now peak wattage on sunny days in 1500-1800 max.

No they just wear out from day one leaving you a mess on your roof.

I have 32 planets on my garage since 2016 my summer electricity bill runs $35 month I run the AC all day and have 2 100 gallon saltwater fish tanks!

@@shelleysmith287 I believe you’re not just paying $35 a month because you’re leaving out the cost of your “planets”

A good metal roof is the way to go.

Easy answer, absolutely none of those issues are a problem. And we often do ground mounts. Small wind turbines are absolute garbage in comparison to residential solar panels. I could turn off a couple of LED lightbulbs and more than make up for what one of those little micro turbines makes even at 20 miles an hour of wind.

this, I've said it many times, there are more small wind turbines on youtube than on the roofs of houses

@@mynameisgiovannigiorgio1027 Exactly. People are just uneducated in mathematics and can't comprehend reality.

That's the calculation everyone needs to start with, along with a table of the prevalent winds in their location. Keep in mind that there are other factors: for instance RidgeBlade claim that a sloped roof will act as a sort of funnel, effectively increasing wind speeds as they pass through the turbines mounted on the rooftop. I'd like to see some hard numbers on that assumption...

thank you very much. keep us updated!

It definitely has its advantage in sun poor regions. But also its downsides. I think with new innovations and adoption the prices will also fall massively as it was with sola panels.

There are motionless wind generation systems now but you'll have to wait awhile for commercial production and they will likely have lower efficiencies.

Don't hold your breath. The physics is against it.

and in cooler climates.

It isn't a matter of wind versus solar, you're allowed to have both.

😂👍🏼

Wear and tear is definitely a disadvantage over solar panels.

Snow isn't particularly good for solar panels either unless you have the panels at steep angles on mounts or have auxiliary heated panels during snowfalls. However, it should be noted that Ridgeblade is a Canadian venture.

Windy location is crucial. A solid wind analysis for your location before installation is a must do to see if it is even profitable. The Idea is to upgrade these turbines modular as you need. But as you see in the Video way too expensive at the moment. And the Ridgeblade alone is capable to produce way more than 1000w and complementary with solar, could be able to provide 100% year long. We found also other new turbines with up to 10.000W which we will represent in another video. Thanks for your valuable comment 🙏🏽

1kw/h is going to be enough to run a house on standby overnight, and probably enough to also run a TV. So if you had solar and battery, you would either slowly drain the battery or slightly charge it with wind once you finish your high intensity electrical usage, such as cooking etc... (I'm also assuming you aren't running your AC to heat/cool)

@@harrisonbs Remove the /h and your units will be correct. Watts already contains units of time. [Watts] = ([joules] /[seconds]) Adding / hours makes no sense and is incorrect. Appliances consume watts not watts/h.

@@deang5622 that is absolutely incorrect! Power is instantaneous and energy is power in overtime. Thanks for your absolutely incorrect conclusion.

@@boblatkey7160 Don't argue with me. I have a university degree in this subject Everything I said was 100% correct. Come back to me when you have got a degree in it. If you don't believe what I have said, then I suggest you go research it, but I doubt you have the mental capacity to understand it. Until then, STFU. Power is measured in watts and it is equivalent to joules per second, and yes it is instaneous. The units of power absolutely does not contain time. So your /h in the units is totally wrong. There are two quantities: power in W (or kW) and energy in kWh. There is no such unit as kW/h. And kWh is not pronounced kilowatts per hour, which is what kW/h means. The units are kWh which is killowatt-hours. No division. No per. It is very clear your grasp of the fundamentals is severely lacking. Now stop being a prick and learn from what I have told you. I am sick to death of arrogant fools like you that think you know what you are talking about when clearly you have not even mastered the fundamentals and you go up against someone that knows far more about this and think you know more. Well I have news for you, you don't know more than I do. So get off your high horse and go research it properly.

Everything needs some sort of maintenance, even Solar Panels need to be cleaned and connections checked regularly. Whether manually or robotically.

Possibly so. But when the sun don't shine you need an alternative way to generate power. Or, increase the surface area of panels to a sufficient degree that you can continue to generate a worthwhile amount of electricity under 100% cloud.

Damn insane numbers. Some places are really windy and worth of thinking about wind turbines.

Good points. Thanks

Hey. I have actually contacted the architect offices that are mounting the Ridgeblade in their projects. I will place all the Informations I get from them in my next Home Wind Turbine Video along with other options.

I don't think Ridgeblade is at the production levels needed to be easily purchased by an average homeowner just yet. Let's hope they can scale up without going out of business.

Just weld them into a privacy fence.

At some areas its actually really windy 🌬️
