  1. Here's why convenience stores are not rushing to install EV chargers

    That would have been '89 or '90. Our city had a Great Lakes shipyard, regional iron ore mines, rail and a still operating steam works, so lots of welding very large steel. I think it was used mostly for preheating thick plates and cutting scrap.

    I think it has something to do with igniting HOH baloons filled by water electrolysis in high school physics. Its dramatic, common, easy to understand, and apparently so simple a (supervised)child can do it. Auto shop class experimented with HOH injection, and metal shop demonstrated...
  3. Here's why convenience stores are not rushing to install EV chargers

    Yeah, sorry bout that. It wasn't intended as a lecture. What you got was stream of consciousness as I processed these thoughts for the first time. Thus no time to Google without becoming distracted. Writing them down helped me organize my thoughts and I didn't want to stop writing till I...

    Part of an Amazon review by Ken Caldeira I'm happy to be counted among those ignorant people and confused by those that don't like that kind of thinking. Because when you are ignorant, how else do you get started?

    Ok. All that solar energy striking the earth is creating a massive demand for air conditioning. Why don't we have solar air conditioners at every bus stop and building on earth? If solar cannot even directly solve the problems it directly causes, how is it going to solve all our other energy...

    The oil reserve isn't used every day. True. It is used in the event of a market upset. Do you think that means it does not serve an important function every day? One important function is to deter short term gouging during brief shortages and delay negotiations of future oil purchases until...

    A 42 gallon barrel of oil is roughly 1,700 kilowatt hours. That is the figure I used when doing the oil reserve comparison. The number of watts it takes to accelerate a weight over a distance is consistent regardless of the energy form used. Efficiency is a function of the machine selected...
  8. FSD Using Cameras in Rain??

    True. But there are at least a dozen people that would pay a million .five each to be the only people in the world with a Cybertruck for a year. Missed opportunity Tesla. "Full" autonomous driving will always be a moving target as new features are discovered and implemented. Everything...
  9. Cybertruck launching boat...

    If the bed is intended to be full of water and still waterproof, is there any hope that midgate is a thing? I can't imagine a sliding gate that is waterproof.

    Touche. Absolutely correct. Power companies do not have the mandate to protect the citizens of the United States. The Federal government does. Primary investment in non oil bulk energy storage would need to come from a National security imperative in order to overcome profit motive. The same...

    True, but... I think we need both. Sorry to continue off topic. Around 5,000,000kwh of Megapacks are currently installed according to https://www.tesla.com/megapack. It would require multiplying the entire worldwide installed base of Megapacks 242,760 times to equal the 1,213,800,000,000kwh...
  12. Here's why convenience stores are not rushing to install EV chargers

    It was a tangent. I thought I understood something about hydrogen energy density, but when I started to compare it to oil it is nowere even close. I'm hearing constant bellyaching about fuel prices, but frankly they are quite stable compared to what will happen when we don't have oil to back...
  13. Here's why convenience stores are not rushing to install EV chargers

    I was thinking "where should we put all the excess energy produced by wind and solar? We should probably start building up a reserve." Ugh. I mathed. Probably screwed it up. Hydrogen has an advantage by weight, but diesel has more than 3 times the energy in the same volume as liquefied...
  14. Amphibious Cybertruck

    There are some fairly crucial details missing, like how to drive onto a trailer that is already attached to your bumper. Or how a trailer slides out from under the truck and parks itself on a ramp. But there are some good ideas in there. Make boat weight an optional temporary load. Use...
  15. Amphibious Cybertruck

    I want to have that option, but certainly understand your desire to not pay for it if you wont use it. Waterproofness requires a lot of careful engineering when done well and a lot of crack filling goop when done poorly. Its anyone's guess what mixture we get. Running 2 different assembly...
  16. Here's why convenience stores are not rushing to install EV chargers

    But that would be less ironic, and potentially drive that Alanis Morissette tune out of my head. Is the fuel cell process technically combustion(an exothermic oxidizing process)? It occurs inside the fuel cell? Thats close enough to keep me groovin.
  17. Here's why convenience stores are not rushing to install EV chargers

    I never thought hydrogen made sense for vehicles, but as a fixed local energy storage it makes sense because it requires no distribution network except the electrical grid. The real trick is safely automating hydrolysis, purification(dangerous to store unless pure), H storage, electrolyte and...
  18. Cybertruck launching boat...

    Invasive species are not trash. Do not throw them in the trash which gets transported overland by garbage trucks and buried by a different body of water. That is the whole thing the laws are trying to avoid. You are supposed to inspect your boat for invasive species at the ramp and leave them...
  19. Cybertruck is waterproof enough to serve as a boat to cross rivers, lakes & calm seas -- confirms Musk 🚤

    No. Treads are flexible. Tracks are rigid. Like ramps are rigid. If you want to equate it to treads, it is just the bottom, useful halfs of 2 treads, without imposing all the permanent mobility constraints of treads, except while they are actually deployed. Like these...
