  1. A teensy-weensy little bit of research or even watching the video will show you that the ball very quickly stabilizes in the centre of the vortex, in the centre of the channel.

  2. It's a vortex which increases the silt capacity through the machine & it's installed vertically, any silt which drops out due to extracted power will immediately rejoin the silt capacity of the main flow – silting is a non-issue here.

  3. ​ @tulpasconstructor2711 turbine blades are not actually "non-degradable", they degrade in UV light. They do seem to be non-BIOdegradable so when they're being stockpiled for recycling they're buried because it's cheaper than building structures to cover them. And yes, they are being recycled. That's slow at the moment because there's not yet enough blades to recycle (blades are lasting up to 25 years in real-world situations) so "economies of scale" haven't kicked in yet but they will.

  4. yes but prone to barnacles, weed etc

  5. ​ @ZirothTech you should have laid that out clearly in the video, in the description & in a pinned comment. You are wasting our time & it's not appreciated.

  6. 20ms changeover time in your advert is rubbish, all your computer-based systems will reset in half that time!

  7. 12:51 underfloor heating is brilliant! That's why the Romans used it.

  8. 6:52 20ms is appalling! All your computerised systems will shutdown or reset! Get below 10ms & you'll start getting an interesting product.

  9. it's likely to work but I would guess the efficiency is poor.

  10. LK99 hasn't passed peer review

  11. 7:04 55°C/131°F is pushing the limits given Global Warming & the low temperatures are even more worrying in some climates, especially Europe when the AMOC collapses or northern latitudes now. Something so central to your domestic situation needs to do better. Much better!

  12. ​ @ZirothTech I have an intense dislike for misleading titles, I'm certain I'm not alone in that. It feels like you're lying. 😢

  13. ​ @74_Green it's only road use where battery-electric was fully replaced by internal combustion for a few decades, industrial applications never stopped using batteries widely. USA's weird half-regulated markets allowed Exide to buy the patents & close the factories for the far superior Nickel-Iron (NiFe) battery which would have tided over on-road applications till nickel-cadmium & then lithium came along but even with that there were occasional forays into battery-electric like Bedford's electric "CF" model which used surprisingly few lead-acid batteries in a simply-converted light van (Ford Transit size).

  14. ​ @glen.simpson the USA's weird half-regulated marketplace is the reason. Steam & battery-electric were fairly mature but still improving technologies when internal-combustion came along & just swept them away for on-road applications, swept them away with aggressive & often lying marketing selling dreams not realities.

  15. 2:15 Kelvin is an absolute scale not a relative scale -- it doesn't have degrees! Relative scales like Celcius & Fahrenheit have degrees (100° between the triple-point & boiling point of water & between the melting point of mercury & blood heat respectively).

  16. efficiency goes up with turbine speed, modern turbines spin as fast as the materials allow.

  17. 10:14 that looks like it's in the "trolling motor" category -- just poweful enough to keep fishing nets straight.

  18.  @fatalitycs  do you mean 8:10? 7:16? 7:35?
