Hearted Youtube comments on Two Bit da Vinci (@TwoBitDaVinci) channel.

  1. Really interesting and informative. I've heard convincing (to me) arguments in favour of molten salt reactors and I wonder how these stack up against the HTGRs talked about in this video.

  2. The Roadster is what I’m waiting for. Not for the “smack down”, we’ll, yes, for the smack down but also for the tech that appears to be building up in this car. New batteries, motors, range, top speed.

  3. This video needs a part II. So much to talk about in greater detail.

  5. In Denmark Facebook is already using heat from their serverpark to heat homes. It's already happening.

  6. This is the best explanation of the difference between ICE car software and the Tesla car software. It shows why Tesla is on a whole other level and is way ahead of the competition. Thanks.

  7. Very nice video fellas, learned a few things about batteries, good job.

  8. Thanks for some really good, in-depth info... I'm in the research stage of building a home on wheels, and you answered a number of questions that I've had. More importantly a number of questions that I hadn't even considered yet... Much Thanks!

  9. This is excellent research and a great historical tutorial video. I lived on Oahu for 35 years and traveled to Maui frequently. All three residents I lived in were older single wall, tongue and groove, 1 inch wooden construction homes and were well ventilated to disparate heat in the summer. In other words, a tinder box but very practical. This my first time on Two Bit and new subscriber. Prayers for those who lost everything and to the families who lost loved ones. Mahalo.

  10. Where is the money coming from to do these videos? The animation alone must have taken weeks.... subscribed (at 4:35 you mean WHrs/Kg not watts)

  11. The answer is not just electric cars. It's also a cleaner energy grid. We need to drop coal and petroleum everywhere we can.

  12. It's great that you've put this one out there. As a former freight conductor with Union Pacific, we pulled these 2 mile long trains from Northlake, IL(Chicago) to Clinton, Iowa. We called them "Bomb Trains", because that's basically what they are. it could have been a bearing go bad or it would have also been a brake that was in the engaged position., that will have the same outcome. Anyway, great video as always. Thanks. 👍

  13. This is incredibly cool and exciting. Looking forward to it. but it's also misleading, because an Earthship really is a very specific thing and this isn't that. Cool nonetheless.

  14. Batteries are the key to long term success. Another great video.
    62
  15. Great collaboration. Hope you can make this a regular thing.

  16. I just accepted the Tesla roof tile estimate, I would love to have a Tesla HVAC system.

  17. As someone in the HVAC industry, I am surprised I hadn't heard anything about this technology before. Great work!

  18. These last three Elon purchases are brilliant. Maxwell for the ultracapacitor, Hibar for the production process and DeepScale for full autonomy support. Soon we will set up Gigafab 4 in Germany and may start production for Europe as early as 2022.

  19. Hoping FSD will drive me around in 10 yrs before my kids take my “keys” (phone) away. 👴🏻

  20. Mark my words. Elon just set the auto industry free to design! Watch and see!

  21. Such a cool project!! Buuut I think you might mean that you're turning your home into a passive house, not an earthship. I've always seen earthships referred to as homes that are build with recycled tires and compressed earth. Still, I'm really excited to follow this adventure!

  22. 30 yrs in uk is considered a new build almost. My 100yr old house isnt considered old as half the towns houses are 100s of years old n zero stigma or desirability issues related to their age. People like how solid they are, with better room sizes, high ceilings, n better noise insulation

  23. As an IT guy I'm thinking about the compute power behind all this. Haven't been to Vegas in 30 years but this could be a reason to drop by, for the right event. Seat prices seem reasonable.
    58
  24. Do you mean hurricane? Tornado? Or both?
    58
  25. Well Sterling engines are big hunks of metal. So if you use Sterling engines as heat sinks for your Bitcoin mining rig, you could probably claw back a significant amount of waste heat. I guess I should watch the video now.

  26. Desalination would be an extreme leap forward.
    58
  27. looks impressive, and they aren't just saying years down the road like most of these, they're saying this year. if it works as expected, and is scalable(even at smaller scale) it could change a lot of the way we think about heat.
    57
  28. The 2020's will be the most advanced decade in digital advancement. What we will see in the next 10 years will be phenomenal. The way we live now will be nothing like what we see now.

  29. This needs to be combined with regenerating the local flora and root systems. One of the major contributing factors to drought is lack of water retention in the soil. The soil needs a healthy micro biome and root system from local plants to properly retain water and recharge the aquifers. When the land above is dry, cracked or pavement... that water will run off and never recharge the local sources.

  30. One of the best descriptions of both solar and the Power Wall

  31. You recommend not running seat heaters, but it's much more energy efficient to run those with reduced cabin temps since the heat is direct to your body, and not dispersed through air in the cabin.

  32. Thank you so much for this report that I forwarded to my relatives, Ricky! You are helping keep the group mind of our humanity thinking rationally about where we are with regards to our massive military might that we ship around the world. Peace

  33. Swap-on improvements are some of the most impactful, especially with the impressive gains these props bring.
    55
  34. Always quality content my friend. Keep up the hard work!

  35. Battery Day is not made for investors. Its made for engineer if anything.
    55
  36. You should watch Jack Rickard video on the Cibertruck, great analysis too.
    55
  37. This is one of the most helpful and truthful videos about supercapacitors and graphene out there. Thanks so much for this amazing content!
    54
  38. Greatest truck in the world!
    53
  39. good job explaining the cells strategy. Interesting times - with Tesla model 3 ramping, we'll see it all prove out well or flop on it's own weight... I'm wishing them well !
    53
  40. Well, this phenomenon would certainly explain why dense forests tend to cool down the air and induce precipitation. Think about it: if the forest canopy is absorbing most wavelengths from the spectrum except for green light , and is in fact reflecting it; that means that by clear-cutting entire areas we are reducing the amount of water that evaporates and precipitates and thus, getting more heat to the surface with less evaporation.
    53
  41. Finally a video about that topic that included all the critical and often forgotten aspects..well done!
    52
  42. People should press thumb up button more frequently over here.
    52
  43. I work in the HVAC field and I've always wondered why we aren't capturing that water and using it. There is bacteria to worry about but it's not like we don't already know how to sanitize water.
    52
  44. Adam Savage (of Mythbuster fame) over on tested did a one day build of Cool Suit using a Tiny phase change heat exchanger cooling an old 1975 British fighter pilot tube suit. Shrink it down a bit more (use micro or nano tech) and you could have enough cooling to keep someone cool in the heat of Arrakis. As to how to power it, use strategically placed Piezoelectric material that would generate electricity from movement. I agree that waste collection and recycling is not possible, but that % lost through breathing is totally possible to capture if you pass it over a heat exchange before expelling it. It would be like the moisture collected on an AC on hot humid day.

  45. Right On Dude. I'm a car guy, how's that you might say. I'm a Detroiter living in Nashville. In the 60's I was in my teens. And toward the end of the muscle car era. I was modifying and street racing muscle cars in Detroit. But things are moving on now. High horsepower cars are now passe the real cool stuff is in Ev"s. And Tesla is "The leader of the pack." Check out the new Lexus Electric prototype Ev. "We're moving on up" to a better world.

  46. I’m not an engineer so thanks for explaining this in an understandable way

  47. Great review of Battery Day - What a time to live in - Thanks

  48. You can look into the Olmos Irrigation Proyect in Peru, they channeled the water from the very wet east side of the Andes mountains through a 20km tunnel to the very dry west side.

  49.  @TwoBitDaVinci  Yes, their whole coastline is named "skeleton coast" for all of the ships that have run ground there, because of the foggy shores next to desert. People would dehydrate and die there for over a century. There are unable to keep significant populations near their coast so there is an incredibly long stretch without any port cities. They are in a unique situation where the fog never travels inland and turns to rain, often it dispenses northward toward the Atlantic.

  50. Jeez-O-Man, this is just horrible. Nice job and thank you so much for the thorough breakdown and analysis of all the chemicals, mechanical problems, technical issues, and deregulation... You do all of your reporting so calmly. It's so sad that has become political. All those people want is to be home and safe.
