  1.  @Slayer8957  thank you for repeating oil industry propaganda. Actually, no, F*CK OFF WITH YOUR OIL INDUSTRY PROPAGANDA

  2. pressurizing the system is one obvious possibility, there will be others.

  3. Sell your MPP tracker then, there's a gap in the market.

  5. Whatever for? It uses about the same power as a motorcycle engine! Get a grip! Any excuse to mention the latest buzzword!

  6. @Dustin Etts, did you watch the video? All of it?

  7. it occurs to me a retro-reflective coating like traffic cones & road signs might survive long enough to destroy the optics of the laser weapon.

  8. in a wind funnel it's probably better to use the more efficient HAWT types, these score in turbulent conditions.

  9. Um, solar wind? Arthur C Clarke's short story "The wind from the sun" gives quite a good visualization of what happens to something very large & lightweight if you block sunlight with it.

  10. That's interesting, can you provide links, please?

  11. it would probably work but it's at the wrong end of the price curve at the moment

  12. ​ @hattifattener1 that's a waste of a comment – suggest something better or keep quiet

  13. ...and sealed -- this sounds like it's open-to-atmosphere at certain points.

  14.  @5226-p1e  the tides have remained steady for several billion years, they flow in 2 directions alternating twice a day based on astrophysics, currents similarly don't vary much because they're driven by geophysics so are reliable for thousands of years.

  15.  @Go2Results  all I said was that tides are predictable (for centuries in advance), I don't understand your comment.

  16.  @5226-p1e  sorry, I wasn't clear, where grid-scale hydro-power turbines are placed the flow is in either one or 2 specific directions (current or tide) & doesn't vary unlike a wind turbine which has to cope with erratic directions from any point on the compass. Currents are driven by the rotation of the planet & tides by gravitational attraction to moon & sun, the wind is driven by much more chaotic forces. There are places where the flow is turbulent but for a grid-scale installation there's no need to use them (local installations might want to use turbulent flows if there's nothing steady close by). There's more power available in steady flows & it's easier to harness. When tides change direction there's very little power available so it doesn't matter that turbines take a while to change direction, watch some time-lapses of boats at anchor & you'll see what I mean.

  17. If you can't be bothered to research your topic don't post a derogatory comment 😂

  18.  @ICDeadPeeps  the world's first city, Çatalhöyük (approx 7,100BC to 5,700BC, population up to 10,000), didn't have streets, access was across the roofs & each dwelling had a hatch & ladder. The wide tree-lined boulevards of modern cities weren't even a consideration.

  19. We are on track for 3.7°C to 4°C if current pledges are upheld, something which seems unlikely. I'm just glad I'm old enough that I'll be dead before it really 'hits the fan'. My children aren't going to like it though.

  20.  @antronx7  propane liquifies at quite high pressure too, you can hear the pump struggling when it fills up your campervan LPG tank.

  21. partly because it's a highly mobile multi-part system that might not still be there once you've figured out where it is & sent enough missiles at it to overwhelm it.

  22. it's way too late to avoid this war, it's already been going 150 years & won't end till one side kicks the other out of the country.

  23. The Zionists started with sticks & guns, Palestinians weren't & still aren't allowed even that, just a headscarf slingshot & rocks off the ground. The creation of Israel was the UN attempting to impose a "2 State solution" but it was never policed so history has unfolded the way it has.

  24. I don't see why they would remove any component of the air?

  25.  @antronx7  does Lake Ontario have flow? If so that thousand years per degree is being distributed across other places, I'm guessing the Atlantic...

  26. 3:47 in the UK we've been told that Hinckley Point C is expected to operate for 35 years though the way they've coaxed older plants along that may well turn into 60 years.

  27. this is how desalination currently works

  28. that's how desalination filters work.

  29.  @WilliamSantos-cv8rr  none of that matters because we're looking at trends not absolute numbers.

  31. there have been plans for barrages since at least the 1700s (mostly near the nuclear power plant at Hinckley) but none have happened, the closest so far is the Swansea Bay lagoon which is fully funded & fully designed, with permission from the Welsh government, it's just waiting for permission from the English government

  32. The UK has pumped-storage hydro for exactly that purpose, pumped-hydro & nuclear were built in tandem in the early days so nuclear could run hotter (& produce more weapons-grade plutonium).

  33.  @DaveEtchells  so the technicians (& consumers) need to go through their unions & government to refuse to work on bottom-dollar equipment that doesn't have trustworthy gauges built-in & also doesn't have leak-proof test points. The manufacturers will sort their kit out pretty quickly. The difference between no gauge & a quality gauge is a few cents at manufacturing volumes, there's no proper excuse. Problems have solutions

  34.  @DaveEtchells  you're dealing with ammonia several times every single day of your life, it's part of the smell of urine. Problems come when there's lots of it like in a factory but factories have been finding solutions for many centuries, it's a well understood material.

  35.  @allah___maadarchod  they're working on that

  36.  @ipp_tutor  the end of copper is in sight, we've dug up almost all of it which means that transformers are becoming more expensive plus we're getting more worried about losses so electronic Voltage changing is rapidly taking over the networks.

  37.  @johnschneider931  many domestic grid-tied inverters balance themselves to the grid's loading by sensing frequency already, making this mandatory shouldn't be difficult even at a global level, thus automating load balancing to an extent. I understand the infrastructure for UK's Smart Meters can also signal from the grid for domestic generation to increase or decrease supply to the grid & there is a mechanism for large consumers to be requested to disconnect loads, eg Tesco's refrigerators are switched off for 15 minutes on request from the National Grid.

  38.  @sz5736p  the 300 mile transmission limit you cite has already been superseded by a large margin. I don't pretend to know the physics of it but it can be seen 'on the ground'.

  39.  @daivonclark5151  at the time the world's navies were transitioning from coal to oil "who controls the oil controls the world" was reasonably true, that controller was the British Empire, but then the Empire collapsed & lost control of the Arabian oil, the 1953 installation of the Shah of Iran was Britain's last significant attempt. Since then OPEC & OPEC+ have formed & they're not interested in World Domination, their one major shutdown in 1973 was solely to inflate the price, nothing political. USA attempts political control via oil but it's success is limited (see Venezuela) & Russia is trying now but again with limited success (see Hungary & the EU). Oil is distributed worldwide about as evenly as potential for renewables (every country has some, a few countries have a lot) so the potential for attempts at domination are still there.

  40.  @sjsomething4936  if you believe the hippies what we're seeing is the last throes of the Piscean Age & we're already transitioning to the Aquarian Age so it will all settle down soon.

  41.  @sjsomething4936  whilst sufficient generation from renewables & very long-term resources like geothermal are definitely possible we suffer from politics & from fashion so it will take a very long time for this to happen.

  42.  @ThomasBomb45  no, Ukraine's energy problems are from the invasion & Russia blowing up infrastructure. Ukraine generates its own electricity & transmission lines for electricity, gas & oil all work just as well in one direction as the other, Ukraine can & does take supplies from all its neighbours. There are problems where those neighbours have become overly-reliant on Russian supplies so cannot supply Ukraine but that situation is being resolved.

  43. oil refineries can already take in any hydrocarbon & convert it into any other hydrocarbon, that part doesn't need to be re-invented.

  44. 0:22 we were told nuclear electricity was going to be so cheap it would be un-meterable. How did that turn into the most expensive by far? Strike Price for solar is around 5p, it's over 95p for nuclear!

  45.  @gerryflores88  I think the forces will be more comparable to hulls than propellers but yes, erosion is a consideration.

  47. If you're thinking about collecting lightning you'll want to check out Catatumbo lightning it's where the most lightning strikes on Earth happen. There's a Wikipedia page with that title.

  48. Swedish submarines use that heat to run Stirling-cycle engines to charge the propulsion batteries.

  49. USA's retirement age is blurred with eligibility for various components varying between ages 62 & 70.

  50. You have taken an overly-simplistic view of the role of robots in employment statistics, in reality employment increases with adoption of robots.
