    Commercial Wind Blades made from Hemp Fiber which is made into a mat has stronger fibers then glass grows faster than Bambo and is easier to recycle. Hemp fibers also absorb Resin as good or better than glass or Balsa wood.

    I remember the bamboo wind turbine video ! I have a Q about the old blades, as they seem to "go on forever". Why aren't they just re-used somewhere where less size is more appropriate? We could use some smaller ones here where I live. Or - could they be repurposed to be used in estuary water generators. It does seem wicked to just bury them. It's like putting a hat you don't like in the bin when you've only worn it once and not giving it to the charity shop (which is where I get all my hats from😄)
    Another great video ! thank you.

      The scaling down reduces size but maintains the mass per ft of bigger blades, harder to drive a smaller blade due to weight. If the material was malleable we would be in bussiness.

    Mr. Robert-Smith I have a question regarding vacuum, 'flame-licker' engines. I hope this is not an inappropriate place to ask... All over RUclips there are videos of flame lickers with people stating that it is the cooling of gasses sucked into the chamber which result in the engine's motive force.
    I disagree with this, and would like to hear your take on it. it is my tentative belief that the flame licker engine is running on the drawn in plasma state of energy present in the flame that it sucks in. I think that the ions and electrons of the flame are sucked into the cylinder where, once the shutter closes, they cannot fill the 3 dimensional space they have now become trapped in - the plasma is just energy, not uncombusted gaseous particles that take up space - therefore a vacuum is left as the plasma dissipates, which in turn draws in the piston. I know that some amount of gasses are sucked in, but I think that those partially combusted gasses that may be sucked in, are more of a transport mechanism for the developed plasma than the primary motive force. If it were just hot gasses cooling then I don't believe the engine would ever run, there has to be a stronger initial force for the first cycle to lead to the second.
    The nature of the electron/ion plasma of the flame never seems to be discussed, it is always "hot gasses" & I just don't think that would be enough, but I can't figure out how to actually quantify or test my theory of plasma dissipation as the motive force. If it's truly just hot gasses, then flame would not be necessary which should mean that a flame licker would run on superheated air, without any flame present - but I don't think that it will. I think the actual plasma of the flame is necessary. I don't have a source of superheated air to test my theory. Probably wrong but, would like to be convinced by someone smarter, that I'm wrong.
    I am happy to become better educated & so better comprehend what is going on. If some day you might take on the question, why does a flame licker 'really' run, I would be very intrigued! Thank you for your dedication to explaining the science of harnessing energy to do work! I really should donate to you for asking a question of such magnitude but alas I am poor.

    Why try to totally break down the fiberglass blades??? We have a homelessness problem. Those could be the start of tiny homes. Think cross sections would be more fire resistant than tents, as well as have more usable surfaces, impervious to weather, rodent resistant, etc. Reusing this way reduces many issues with other types of recycling.

    Laid flat, they can be used as pedestrian bridges with spans as long as the blades, the biggest redundant blades now over 200 ft. If turned on their sides and bolted together as the base upon which a surface could be constructed, they could be used as vehicular bridges. These could be useful in Ukraine to replace bridges destroyed in the war. As for the Dutch banning the disposal of them in landfill, with rising sea level, they are mad. They need everything that they can get hold of to raise the level of their land ... it isn't much, but as the old woman said whilst piddling in the Sea, "Every Little helps," .... or to make gigantic lily pads on which they could build houses. According to the World Meteorological Organisation, sea level rose by 1.87 inches in the 10 years 2014-2023 and it is accelerating. The Dutch do not have long to go. Contrary to the usual hyperbole, only a few square miles of the Netherlands are below sea level ... that is below low spring tide. Huge areas are inter-tidal I.e. above low spring tide level but below the peak of a surge spring tide BUT as sea level rises, ever increasing area WILL be below low spring tide requiring more and more energy to power the pumps. In addition to the sea-level rise, because of isostatic settlement, the Netherlands like Southern England is sinking back into the Earth. London sank a full inch in the last 11 years.

    • @justinterested5819
      @justinterested5819 7 месяцев назад

      This is like totally wrong:
      One Wind Turbine with 5 MW on a medicore location produces around 10 000MWh per year, or 250 000 MWh over 25 years.
      One Ton of Coal as example holds around 5MWh for comparison. So one Wind Turbine can produce the energy equivalent of 50 000 Tons of Coal. Or 25 000 Tons of Oil/Natural Gas (both who have an energy density of around 10 MWh/Ton). This doesnt include conversion losses (or gains via heat pumps). If you use the energy for heating, you can make 750 000 MWh with an average heat pump (SCOP of around 3, modern buildings can hit 4), while coal stays around the same (since you need to convert coal to electricity first, what wastes 2/3 of the energy).
      And that ignores the fact that the CO2 is dumped right where it is being produced, with no control what happens to it. Producing 250 000 MWh of Electricity from Natural Gas (0.4 Tons of CO2/MWh) emitts around 100 000 Tons of CO2. What has a far lower density than Wind turbine Blades (1 Ton of CO2 requires around 500m³ of Space, 100 000 Tons of CO2 would need 50 000 000 m³ of Space). Even if you just lay down the wind power plant as a whole, dig it in and leave alone the area above it, it would need far less space, and would cause far less problems than CO2. Compare that to wind turbine blades: very heavy wind turbine blades weigh around 150 tons each (from 25 MW offshore Turbines), so together they have a mass of 450 tons.
      Fiber Glass has a density of around 2tons/m³. Meaning you would need only 225m³ of Space. Half of that of *1* ton of CO2.

    Quite ironic that they seem incompetent when designing wind turbine blades .
    I smell a rat and I bet the sales and marketing teams / politicians have got something to do with it . 🤔🙄
    Funny how the thousands of GRP boats are still afloat and they suffer from osmosis to a far greater extent than these blades .
    UV resistance of the resin may the the key factor but one can guarantee there’s a simple way round it .
    Bamboo/ flax/ hemp is way better than balsa as a reinforcement plus there’s coremat , sorric and many other alternatives used in the composites industry.
