      you need to maintain clearance between the blade tips and the tower. Canards, would take up that clearance, unless the tips faced away from the tower. That could cause flutter, and instability. Both huge enemies of turbine blades.

    @Argrouk Před 5 lety +4

    So to combat inefficient blades with large bearings on a sturdy base, you make a small model, that when scaled up will require smaller inefficient blades on powerful bearings, tethered to a very sturdy base... but you're going to wave it around?
    Someone didn't do their thinking/maths properly at an early stage.
    The larger it gets, the harder it is going to be to launch, the smaller the window of useable wind. It will need a stronger and stronger cable, and require more power for hover and return modes. It has a much larger hazardous air space requirement, which could have a much larger bird strike impact both on the technology and the ecosystem.... I could go on.
    The reason for all of the heavy equipment holding up the small bit that does all of the work in a conventional design, is that it is needed to make it both useful and safe, as you have just found out at great expense.
    What happens when a cable snaps?

  • @poknatinpokkers5289
    @poknatinpokkers5289 Před 5 lety +1

    I'm assuming this uses carbon brushes for electric current to pass through pivot points. of it doesn't have that, the wire or cable could twist so much and do some plastic damage to itself. that said, i can imagine replacing carbon brushes on the wing and the tether itself and think about the expense this accumulates...

    @albertrogers8537 Před 7 lety +6

    It makes not the slightest difference how you use it, the wind is capricious, it is fickle, it is intermittent, its pettern of occurrence is a random walk. If you cannot depend upon an electrical energy resource on the grid, you must provide against the rate at which it might disappear. You must do so with dispatchable resources, which means generators that within periods of time that are not large compared with one cycle of a 60 Hz grid's voltage, can be brought on line to provide the demanded, or "missing" power.
    There are people who tell you that the cost of energy storage is coming down. Look it up and estimate what just one gigawatt_week would cost, capable of delivering one gigawatt of power.

    • @YodaWhat
      @YodaWhat Před 6 lety +1

      Albert Rogers -- Tsk, tsk, such negativity. Is that a _strawman argument,_ or did you just contradict yourself? Let me straighten you out... Providing backup Power for short-term variations does not require a massive amount of stored Energy. Long-term variations in power leave long times to bring online those back-up systems which are good for that kind of load. Also, quite apart from the usual wind variations you were probably thinking about, this kind of flying system will operate at high altitudes where the wind is much stronger and more constant. When widely deployed, some of them will always be in some windy place. When wind power is in excess of need and/or beyond what their local grid can accept, water can be electrolyzed and the hydrogen put into the natural gas pipeline network, or used to synthesize zero-net emission hydrocarbons with CO2 from the atmosphere. Heck, these flying powerplants can even carry wireless communication equipment to augment and back-up the terrestrial communications networks, and do so at far lower cost than commsats in space.

    The problem with wind energy is that they keep trying to be base load power and wind is not suitable for that. If they lifted water or compressed air and then generated peak load electricity from that they could generate clean current and make the money to pay for the system without cash subsidies.
    Fossil fuel get reduced taxes to reduce consumer costs and it is called a subsidy.

      The Washington Post
      Could wind power ever meet the world’s energy
      needs?
      By Brad Plumer September 10, 2012
      At the moment, wind power supplies about 4.1 percent of electric power in the United States. Still a bit player.
      Yet there's a whole lot of untapped wind left in the world. Wind whipping through the Great Plains. Wind gusting
      off the shores. Wind circulating high up in the sky. So what would happen if we tried to harvest all of that wind?
      We'd have enough energy to power the world. At least in theory. A new study published this week in Nature
      Climate Change finds that there's enough wind potential both on the Earth's surface and up in the atmosphere to
      power human civilization 100 times over. Right now, humans use about 18 terawatts of power worldwide. And,
      technically, the study found, we could extract about 400 terawatts of wind power from the Earth's surface and
      1,800 terawatts of power from the upper atmosphere.
      This isn't what's likely - just what's possible. As Kate Marvel, a researcher at Lawrence Livermore National
      Laboratory, explains, this paper mainly looks at wind power's maximum potential. "We were looking at the
      geophysical limits of what the Earth could handle," Marvel says. "We didn't necessarily restrict our study to what
      was feasible." (Marvel coauthored
      the study with Ken Caldeira and Ben Kravitz of the Carnegie Institution for
      Science.)

Just an excuse to keep University Academics in a job playing with model aeroplanes. Sorry Uni folk as much as I love you guys, you always do things the hard way.
    A better and simpler wind generators work with 44 gallon drums cut in half lengthways fitted to vertical mount drive shaft generators so no swivel is required on the "blades"( 2x 44 gallon drum shells ). Generator/s made from Fisher & Pakel washing machine motors at 1kw output for each motor minimum. Also the newer TURBY design has proven to be very good, used in Europe, running at low wind speeds and very low altitudes.
    As no maths or test results were shown - I fail to believe your design is superior.

    How will you solve the problem that these are electromechanical and by nature have moving parts that will battle the wind? How will you solve the problems of friction and dirty electricity and sporadic output? Once again people will look out at the mess on the horizon and wonder where they will get their power and how they will clean up all that broken hardware. Meanwhile, the output from these will have killed people and someone(s) will have used nefarious means and corrupted someone else to put these up and to cover up the huge problems and death. Where are the actual improvements when all it looks like here are that the problems have taken on a new face and the poison has taken on a new frequency? I'm not just badgering, I really want to know, because I am watching people and animals and land die here, and you are working to perpetuate that.
    If you want clean energy start with the concept and reverse engineer. Do not take something that by nature disrupts and wears solidity down and then pump it into life's very core, disrupting and wearing life down. Start with the desired frequency from a source that is actually clean.
    There is more to say on this. Do not cover up problems by making them look different. Each and every engineer that continues to push wind looks blind to physics and the fundamental issues of power generation and transmission in a world in which that very power is, in theory, intended to support life, not destroy it. Whether we like it or not we do have certain constraints if we are going to even make a small effort to support the world we live in.

We have a destructive electric field in the ground now that is killing the burrowing animals - industrial wind turbines are deadly to life in general, and who will be next?
      You did not read my entire post. My suggestions were valid. However, here is an excellent suggestion - don't be so quick to call coal dirty and don't be so quick to throw away what does work.
      Before you criticize people like me ask yourself "what if they are right"? We have already asked ourselves that about your opinion, so we have one up on you. We all came into this being taught 'wind is green'. So, ask me some real questions. That is the way you and I will communicate, because right now you simply appear to be one of the people destroying other people's lives for too high a cost for something that hasn't and still doesn't produce the real power everyone needs.
      Land is a finite resource. Industrial wind turbines use enormous quantities of land and poison that land in the process. Would a re-engineering of the wind turbine techniques take into account the waste of land, the pollution produced by the technology or the destruction from the grounding of the chaos wind energy produces?
      There are a lot of missing pieces right now. Viable solutions are being cast to the wind (literally). That is why I recommend looking at the whole puzzle from new angles - perhaps more PhDs and more thinking and a little less breaking people's backs with bad ideas.

      T Yomama One more thing. Do you really think you are benefiting from the wind industry? Your comments are belittling the very real problems with wind energy and the way that wind industry diverts from what needs to get done.

      +WolfeSandy I am not an ignorant tree hugger... In fact my income is derived purely from oil production. I work for an oil company. I realize that there are issues with wind power but I have , as an electrician, worked in lots of power generation plants in my past in construction, they are non-renewable dirty power. I am sorry that you were lied to by corrupt slick salesman that had your neighborhood convinced that these would be OK to have around you, but wind, solar, hydro (via rivers or tides) power have to be researched. I question your line about dead burrowing animals... They may have moved on due to noise and vibration but there is no way these mills are energizing your ground. You sound plainly ignorant there. Aside from that I have no doubt they are a hateful thing to live under. I simply questioned you on solutions. To say "find a solution and reverse-engineer" is a joke. What is the solution?

      +WolfeSandy one more thing from me also, we are burning around 95 million barrels of oil PER DAY... we need to find alternatives. We need to dramatically increase clean renewable energy production, and equally decrease inefficient usage. We need major breakthroughs in all aspects, how we are living now is not sustainable.
