      Although I love science and I want to be engineer (hardware engineer) ,
      I acknowledge that most of the harm done to humanity and ecosystems is done by the rise of science.
      1. Invention of first vaccine (which caused discovery of other vaccines) lead to global overpopulation
      2. Use of coal and oils in excess caused climate change.
      3.I don't want to add a lot of points because the first point is the worst thing that happened ,and it (overpopulation caused by vaccines) is enough to explain most of the harms that humans are doing on natural resources and it's ecology.
      If Science was only a theoretical thing then this world would be greener.
      And it would be very good if vaccines were very costly so that only some babies can be made safe from diseases.
      (It sounds cruel but dying due to diseases is natural to us.)

      But I am not offending you but I just gave my opinion on your comment.
      😊
      Last thing I want to say is science should include experiment and theory but *should not be applied* at such large scale without thinking about the future generations and existing greenery on earth.

    Literally anything that produces heat as a byproduct could turn the lost heat energy into practical work by strapping a heat engine on top of it
    Eg. A coal fired powerplant is only 33% efficient. Strap one of these bad boys on there and you've got a lot more bang for your buck fuelwise
    I drew a basic diagram of the concept it's a shame you can't post pics

    Most of what he says is complete nonsens. The heat in a combustion engine is a incidental by product it can not use and must remove by the radiator. It is the pressure caused by the explosion that pushes the piston down, nothing else. If it could be done with no heat it would work even better than now. ICE is not nor has ever been a heat engine.
    A steam engine is fairly easy to understand. Boil water get high pressure steam then push a piston with the steam. Boiling of 1 gallon of water turns it in to 1800 gallons of steam. Contain it in a smaller volume and you get pressure. Boiling water in a sealed container is verry dangerous as the verry high pressure can cause it to explode, several steam engines did that in the early days.
    The sterling engine IS a actual heat engine designed by rev Sterling in England but the large "piston" is only used as a air displacer to move the heated and expanded air away from the heat source so it can cool and contract. The small cylinder on top do have a piston that both gets puched by the hotter air and then pulled back down as the air cools and contracts.
    The thermal "generator" running the fan is in fact a Pelletier element run in reverse, they transfer heat by a semi conductor as a solid state heat pump when supplied with power. They are good for some type of heating or cooling but with moderate to low efficiency. When heated and cooled they instead give of electricity but at verry low efficiency.

      "The heat in a combustion engine is a incidental by product it can not use and must remove by the radiator. It is the pressure caused by the explosion that pushes the piston down, nothing else."
      1) Isn't the pressure caused by the explosion due to the temperature increase caused by the explosion? PV = nRT; could also be number of particles increase too in the combustion byproducts but certainly there's a significant temperature increase which would contribute to pressure and to work done on the piston
      2) Isn't the heat that must be removed just *excess* heat corresponding to the part of internal energy that wasn't converted into the work of moving the piston due to not having perfect efficiency?

      @@sammysoil77 no a explosions can have a shock wave that is not hot. This is a internal combustion engine, not a heat engine. If it was a heat engine it wouldn't need combustion.

      Agw is correct.
      A heat engine uses heat as an energy to do work.
      The heat created by the gasoline engine is not used to do the work. It is indeed a by product. If anything, the heat is 100% wasted energy since it wasn't converted into mechanical force at the wheels.
      If cars ran on heat engines, they wouldn't put heat out as exhaust. They would actually cause cooling as they used the heat energy

      @@zachcharo You are quite correct that all heat generated in a gasoline or diesel engine is wasted energy, how ever a heat engine do need a heat source and then it disperses that heat via some type of radiator, so i´m afraid it do not cool any thing as the "cold" side is slightly above ambient temp.

    Great video, did you have some drinks? Your speech seems slurred and your slow reflex to turn off the whistle was tortuous. Cheers.
