  1. It doesn't change the albedo of the land all that much. 20% of the light absorbed in the panels flows out in form of electricity (or is stored in the batteries) and during the night the panels are radiating IR very efficiently, cooling the air around them stronger than the original surface would have. Overall it's probably mostly a wash. In agricultural applications the shade of the panels reduces evaporation, leading to longer growth periods in spring and summer and allowing species that are less adapted to arid conditions to thrive. Solar shading in agriculture will probably go a long way to offset the effects of global warming on farming.

  2. We have plenty of copper in the ground... our old telecommunications cables can all be replaced by fiber. Apart from that... aluminum makes for great conductors.

  3. So when are you going to invest all of YOUR money in a nuclear power plant? That I want to see. ;-)

  4.  @billcichoke2534  How would I delete your post???? I am not YouTube. You are clearly way too emotional about this.

  5. Battery storage is for rapid high load demand. That's the current problem that needs to be solved to stabilize the grids because solar and wind can show intermittencies at the minute time scale. The next longer time scale is four to six hours in summer as AC demand continues even after sunset in states that have warm climates. There is also a mismatch between demand and supply in the early morning hours as businesses are opening before solar has sufficient production capacity. This intra-day storage can be easily met with batteries. The much harder part will be to cover weekly and seasonal supply-demand mismatches, especially for heating.

  6.  @SmartMart1658  The Tesla playbook worked in 2012. It's now 2024.

  7. I love announcements of announcements. They are the cheapest kind of journalism. It costs less than publishing fairytales. ;-)

  8. Cost per cycle is what counts and that can be reduced greatly with battery technologies that have longer lifetime. Once batteries reach the 10,000 cycle mark, their cost impact becomes marginal. We are almost there.

  9. I heard you say that last week about 900 million acres of farmland in the US. Oh, wait... you never said that about farmland. :-)

  10.  @polarbear7255  Yes, you are making a good fool of yourself right now. ;-)

  11. Was it ever alive? ;-)

  12. Awh, you are so cute when you are offended by reality. ;-)

  13. Yes, that is exactly what drives the sales adoption curves. Envy. ;-)

  14.  @FreeKekistann  One could imagine panels that are actually cooling the land by reflecting most of the IR radiation and by having an emission peak for IR wavelength that correspond to the Planck peak at 300K. That would reduce heat load by 30% or so. It does come with some efficiency loss and the production is more expensive, of course. Other possible combinations involve solar and thermal desalination.

  15. In California it was almost 20% of all electricity generation in 2022 and growing rapidly. By the end of the decade it will probably be the largest fraction of the electricity mix.

  16.  @billcichoke2534  Your freedom to make a fool of yourself on the internet is in no way endangered. You are practicing it now. ;-)

  17. Nobody makes them, for one thing. Where is the hydrogen going to come from, anyway? :-)

  18. Why are cheap, high quality EVs a threat? They are a godsend to the consumer. Let's stay real here.

  19. I don't have to be Bosch. I can simply fit a sales adoption model to the current sales curve and predict the same. :-)

  20. You can look at the adoption curves for smart phones, flat screen tvs or the ICE car. They are all similar (s-shaped) and they can all be modeled with fairly simple (two parameter) sales models. It's basically a function of envy. As soon as one of the neighbors has one of something, all the other folks in the neighborhood want it, too. ;-)

  21. Yes, they will ship it in a Lexus a year from now. That's second price, not first. ;-)

  22. Yes, that's why absolutely nobody can afford to build a new nuclear power plant without government guarantees. ;-)

  23.  @nightdipper5178  They weren't laughing the last time a nuclear project went bankrupt and took Westinghouse down with it. ;-)

  24. If you want a curvy truck with sexy eyes, buy the Rivian. It's cutesy, for sure. I like it. If it could sing, it would probably sound like Marylin Monroe in "Santa Baby". It's also cheap. Oh, wait. No, it isn't. It starts at something like 73k. Could Tesla produce a Tesla branded Leaf? Sure. Would you love its 0-60 acceleration of 7.5 seconds and a mediocre crash test rating that puts your kids at risk? Of course you would. Oh, wait... :-)

  25. You need to read the fine print. Round trip efficiency is 80% WITH waste heat. In other words, unless you can get tens or even hundreds of MW of waste heat from somewhere it's very inefficient. Since the storage and retrieval are intermittent, it's also not a good use of the waste heat source, unless you are using it to increase the thermodynamic efficiency of a peaker plant. That, of course, is not an actual storage solution. This is more of a technology looking for an application than an actual solution strategy.

  26. I saw one recently. It's a nice looking car... but the price is way too high. It's a luxury toy and the 9k sales sound about right for a luxury toy.

  27. What anxiety is that? You don't move your car every five minutes. You drive to work and your car is standing in the parking lot for 8h. You drive home and your car is in the garage for 12h. You drive to the mall and you are shopping for 30 minutes or two hours. What's there to be anxious about?

  28. I believe it when I see it. :-)

  29. I don't need a Lucid. I may want one. Sadly for them I can't afford one. And THAT is their problem. Almost nobody can.

  30. We have never seen automakers go bankrupt? Dude... except for half a dozen times already, that is. You need to get a life. I am blocking this channel. ;-)

  31. Yes, that's commonly repeated FUD by the oil and gas industry. ;-)

  32. Why are you so afraid of China? Is that because you aren't competitive? :-)
    1
  33. Or you could look at the sales adoption curve for EVs. ;-)

  34.  @polarbear7255  Cost competitive? Then why did Georgia go bankrupt? The abbreviation of the definition of insanity is spelled "nuclear". ;-)

  35. Even Tesla had to learn the hard way that it's not all that hard to design a good car. It's much harder to mass produce a good car (they are still struggling with that one). It is really, really hard to mass produce a cheap, good car and not lose money on it. That's not Tesla's fault. It's a general, consistent experience in almost every industry. With cars it's just much more expensive than with smaller products to attempt such a feat.

  36. Why would Bosch develop technology that nobody will order? You aren't making any sense here. ;-)

  37. The Chinese can manufacture in the US. Not a problem. There is no legal workaround against that.

  38. You can't pick and chose your investors. I don't know what makes you think that this kind of money can be found in the streets...

  39.  @SmartMart1658  Good luck with that. The stock is cheap. You should sell everything you have and buy the stock. You will become rich in no time. What could go wrong? ;-)

  40. That's a simple supply and demand problem. EV charging stations are very easy to build and can be installed in next to no time. Low income housing is the least concern... the people there are going to be the last ones to buy an EV.

  41.  @ChuckHolland-i4b  Nobody stops you from investing YOUR money in new nuclear plants. :-)

  42. OK, in which case Tesla didn't mess up the truck any more than the entire industry messes up their annual automobile show concept car presentations. Have you ever been able to buy a production car that looked anywhere close to a concept? No. Not until now that is because the Cybertruck actually looks pretty much like the concept. In other words... Tesla takes the cake even in that category. At the very, very least they have delivered on looks. ;-)

  43. Towing doesn't "normally" happen to a vehicle. Over 99% of all vehicles on the road are NOT towing. How do I know? I can watch the street next to my house. Neither is anybody today driving 1000 miles without going to a petrol station. Those who didn't miss 1000 mile range in their gasoline vehicles won't miss 1000 miles of range in their EVs, either. That's 100% of all drivers. ;-)

  44. Did you, by chance, write that on a device made in China? ;-)

  45. That's the kind of powerplant that could supply the entire continent with energy. ;-)

  46.  @billcichoke2534  Good try, but it's just not true.

  47.  @billcichoke2534  YouTube's bots do. If you are getting irritated about that, then this ain't the place for you. They do that a lot lately.

  48.  @billcichoke2534  You are getting all emotional, again. :-)

  49. I could buy expensive pieces of junk from Ford and GM and Toyota etc. for many decades. They call them "trucks". ;-)

  50. Anybody can build a cheap car in China. The inferiority of the Chinese car industry is demonstrated by the fact that they are not even trying to build a cheap car in Europe or the US (which would get them around tariffs). They know that they would fail to be profitable.
