    Thought it was Edison that wanted DC, Tesla AC?

  2. AC was chosen because it was ultimately hell of a lot easier to transform the voltage of it. You also naturally get AC power from a rotating magnet on the end of a turbine-generator so it was simpler in that regard.
    Converting DC back into an AC grid is not a small undertaking.

  3. The best part of that vid was watching that guy spark and smoke himself into oblivion. :D

  4. He does that constantly. In every video.
     
  5. The silly twit hasn't touched upon the main reason why DC is far superior on long distance power transmission though, or involving joining different grids or undersea cables.

    He talks about that in a more recent video.

     
  7. Finally some actual science and engineering (in amongst all the sparks and rubbish). My god I could have saved myself four years on my bachelors if only I had access to YouTube. Not :D

    They can afford to be with all that oil to export.

    DC is not safe for domestic use. AC isn't safe if touched of course but it tends to throw you away from it. DC tenses the muscles solid and grabs you like a vice while you cook.

    They, just like Sweden, can afford to be completely green because we have lots and lots of hydro. Norway gets something like 95% of all their electricity from hydro dams, nothing to do with oil...
    We on the other hand only manage about 40% from hydro but instead we have a couple of nuke plants providing the other 40% and then wind / woodchip fired thermal power plants for the rest.

    Their whole economy depends on oil exports. That's why tiny little farms on poor soil can provide a living and the State can afford to subsidise them every way legally possible. That is why they have such a high standard of living generally. That is how they could afford to build all those tunnels and Tesla charging points and even the hydro-electric plants. Pilchard fishing certainly doesn't bring in that cash.

    Most of their economy maybe but not their electricity generation. Hydro plants are some of the cheapest ways to generate electricity, if Norway did not have any oil they would still have the same amount of hydro plants because it is simply cheaper than any realistic alternative...
     
  13. All the Nordic countries can afford things because they have stiff taxation systems, not just personal taxation for citizens but corporate taxation as well and it is enforced.

    But researchers say the building of dams in Europe and the US reached a peak in the 1960s and has been in decline since then, with more now being dismantled than installed. Hydropower only supplies approximately 6% of US electricity.

    Dams are now being removed at a rate of more than one a week on both sides of the Atlantic.

    I am not surprised reporting by the BBC did nobody check the name of the professor Moran probably had an assistant Teresa Green.

    Hydro plants are far cheaper to build as run of river rather than dam construction.

    Dams have definitely decreased in popularity because they cause pretty huge changes in the local environment, and since most of the low impact sites have already been exploited the ones that are left are the really unpopular ones.
    But hydro plants are still the cheapest way of generating large amounts of electricity especially the ones that are made with just a tunnel between two reservoirs which is a method very often used in Norway...
