  1.  @lephtovermeet  lubrication is not needed, take apart your fishpond pump to see, the rotor/impeller assembly is sealed & often on magnetic bearings, nothing else has bearings.

  2.  @ytSuns26  metals aren't the only option, materials commonly used for boats will work just fine for underwater turbines, concrete, fibreglass & wood last really well underwater

  3.  @mementomori29231  just out of curiosity, which king or queen owned you in the past?

  4. energy storage is already figured out, it's just waiting for people & companies to buy it. I have enough lead-acid batteries for about a day, if I could afford it I would have a month of NiFe batteries, grid-scale seems happy with NiFePO, liquid-metal & Li-ion batteries alongside pumped-storage hydro, pressurized air in caves & molten salt but more tech is coming fast...

  5. Even if it's your home where literally hundreds of generations of your family have grown up surrounded by your olive trees, your livelihood?

  6.  @lephtovermeet  the consumer ultimately pays full price for energy, either directly to the supplier or through taxes which is where the money for subsidies comes from. Ok, imbalanced taxes sometimes mean that some people pay more for energy than others but the principle holds.

  7.  @carlitoxb110  1) not all economies are built on consumption 2) elder people & robots consume services

  8. thorium isn't a cooling salt, it's a fissile material. Its biggest real-world advantage is that you can't make bombs from it.

  9. and when it comes round to your home, where your family has lived for 5,000 years & more? Do you just walk away when a foreigner wanders up & says "goodbye, it's my house now"?

  10. yes but the sun is weak towards the poles because it's travelling through lots more atmosphere. That's how the poles remain frozen

  11.  @gordonmurray3153  the transmission losses on HVDC are orders of magnitude less than AC at any Voltage, long transmission lines are completely feasible & already in use.

  12. That's called "fractional distillation", it's already used but not for separating the components of air because there's more efficient ways of doing it. CO₂ by the way doesn't become liquid if you just chill it, it goes straight to solid. It becomes liquid if you compress it instead. (Nature has some odd stuff).

  13. Also, turning away from the current camera feels disrespectful, turning towards the new camera works better. Watch the news anchors you're copying (it doesn't help anything there either & they often do it to lower the perceived importance of what they're saying).

  14.  @hg2.  no, environmentalists have NOT affected the price of gas. The price of gas is set by Stock Markets & the retailers that sell it to you & your government. Don't you remember the price went negative a couple of years ago? (It was news headlines all over the world) Would environmentalists have allowed that if they had any effect on the prices?

  16. it's already happened & is expanding rapidly.

  17. Frankie Goes to Hollywood - Two Tribes. The song was talking about USA & Russia but the video fits well enough here too.

  18.  @autohmae  market share changes continuously, that's just a feature of capitalism, as long as Tesla can maintain enough share to keep their chargers maintained it really doesn't matter to you & me.

  19.  @jghifiversveiws8729  that's what India is doing, Modi was talking about it at last year's COP

  20.  @gerryflores88  some of the inert rubbers (I'm thinking silicone) are pretty resistant to water abrasion, as are some ceramics, solutions can be found

  21. That's interesting, thank you. Is there a 10 to 20 minute video describing this in more detail? It looks from Wikipedia as if Trump stopped the plans in China but China still has a sodium-based nuclear programme, can you clear up what's happening?

  22. Like a Ridgeblade or Windcrest? Yes you can.

  23. 7:17 so, wind is maybe twice as safe as nuclear & hydro-power or solar maybe 4 times as safe? So, nuclear is the way to go? Hmm... I think recovery time from disaster may be a useful statistic, as well as cost. If a solar panel has a catastrophic failure it will take someone with a dustpan & brush half an hour to clean up the mess & an engineer maybe half a day to replace it. Windmills take longer, maybe weeks. A catastrophe with hydro-power can be a big thing depending what type, a tidal lagoon has minimal impact but a large dam can take a decade to recover. Nuclear? How long has Chernobyl been sitting there? What did the Russian army do to it last month? Has Calder Hall or Windscale been cleaned up & the site repurposed yet?

  24.  @muresandani  "the last" indeed, the scattered radioactive waste will still be polluting the environment centuries after the dead people are forgotten -- go look at Iraq & the "spent uranium" munitions littered all over the countryside...

  25. it doesn't get discussed much because it upsets the lunatics ("it's our sun, we can't give it away") but it's happening anyway & has been for years, most neighbouring countries interconnect their grids & it's not a great leap to use those same interconnections to traverse multiple countries. The EU has done it & is expanding across neighbouring countries quite rapidly.

  26.  @sandyfordd1843  Nickel-Iron (NiFe) batteries were invented for car traction batteries too but skulduggery from lead-acid makers saw the superior tech sidelined.

  28. ammonia is used in some equipment

  29. Gusty turbulent winds mean a HAWT is always facing the wrong direction to catch a gust & in extremes will snap the tail off (yes I have seen it). It's really frustrating having to hold your hat on while watching your windmill gyrating wildly yet not generating power.

  33. CO₂ works at 1000psi apparently

  34. I'm not seeing any detail that isn't Victorian-era tech so all the numbers you're after are out there somewhere. Much has been improved in the intervening century (turbines especially) so look for recent data.

  35.  @gordonmurray3153  with HVDC you are citing problems which have already been overcome & HVDC is installed in & between many countries right now with more following rapidly. For example UK currently has 8 interconnectors to the Continent & to Ireland as well as nationwide distribution all running HVDC. I understand this has been enabled by semiconductor electronics doing away with mechanical switchgear.

  36. That's the market I'm waiting for, there's got to be millions of campervans around. The bearings need to be top quality & easily changed though, there's nothing worse than a noisy bearing resonating through the frame of your 'van.

  37.  @rolandrohde  yep, how do you get "keep left" signs to stay where you put them? 30,000 foot high poles don't seem particularly practical.

  38.  @asandax6  metals can be discounted entirely, there are plenty of other suitable materials. Hardwoods for instance seem to last well underwater.

  39. have you seen what happens inside a toaster?

  40. Not often enough to worry about if the country's economy is stable (so yes, it's an issue in the UK at the moment).

  42. how do you charge it?

  43. 5:19 Palestine was demilitarized soon after the British takeover in 1920 but it wasn't enforced against the Zionists Britain was shipping in. This situation still hasn't changed, a disarmed country trying to hold off an armed invasion which has the support of great empires.

  44.  @factnotfiction5915  "60-100 year lifetime" of a nuclear power plant includes building & cleanup, actual on-grid generation time is less than 30 years

  45.  @TwoBitDaVinci  are you using different title screens in different markets? The one I got was definite clickbait unsupported by the video. This behavior is why I have been watching less of your videos recently.

  46.  @aware2action  your point is explained in the video.

  47. We are already well connected into Europe's DC transmission system with, I think, 4 more connections coming online this year but the Government are working hard to get us cut off, connections to France & Norway went one-way last October because of our Government's bad attitude.
