<p>We have an EV and I figure we will save about $5k or more per 100,000 miles on the fuel costs, but that savings is flipped to a loss if I had to use fast charging all the time. But I'm using $3.50/gallon gas in that math. In Laos gas is almost double that, and electricity is much less than in my math. I get $0.07/kWh at night, but average residential in Laos is $0.031-$0.004 per kWh, so there's a roughly 4x relative advantage based on those price structures. Google says public charging in Laos is between $0.11 and $0.16 per kWh, which means someone using public chargers there would likely still be saving money over a similar gas vehicle.<p>[I asked google for those prices, so my estimates above are only as good as what Gemini gave me]</p>

<p>They did become cheap for a very short time at the front of the pandemic. Specifically sales in the US hit a historic low in April of 2020, almost down to half the monthly volume a few months earlier and four or five months later. I remember this because a family member needed a new car and got a great deal. We were unsure if it was a good deal, because maybe things would get worse but they had a real need for a new vehicle so they did it and looking back were lucky to hit the low point. But your broader point is correct, that was a relatively short blip and arguably much of that missing consumption was just delayed until folks had confidence they would still be employed in the near future.</p>

<p>It is stupid to put a solar panel on top of a car.<p>1. The car's surface is small relative to charging needs. Both have fundamental limits (insolation and aerodynamics) that aren't likely to change much.<p>2. The car's top is not generally flat or even a simple curved surface, so you'll probably be compromising the aerodynamics.<p>3. If the car is parked in a garage, or under a tree, it will not make power. If you're buying the panels, put them where they'll see the sun as much as possible (rooftop, shade awning for parking, etc.) would be better.<p>4. The solar panel will get junked when the car gets junked rather than lasting longer as it would in a stationary environment.<p>5. If the car's battery is full, the panel output can't be used, but see point 1, this will only happen if the car is parked in the sun w/o driving for a number of days, even if it was parked at 80%.</p>

<p>I learned Morse code almost 50 years ago.

If I was having a conversation near my speed limit, a good way to break me was to send a long unusual word</p>

<p>LOL, 25 years ago my neighbors and I were setting off fireworks over a yet-undeveloped part of our neighborhood. We saw police pull into the neighborhood. My family were the cowards who went inside. Our neighbors had to pay a fine. If we'd hung around we'd have paid a fine too.</p>

<p>I don't agree. I think it's a choice that each area has made between law enforcement and local governance. Regarding the St. Louis area, it really depends on which jurisdiction you are in. St. Louis County has over 90 municipalities. The neighboring counties are also fragmented but to a lesser degree. There are areas (mostly more rural) where it is legal and loud, some where it's not legal but enforcement is lacking, and there are quiet areas in which I assume enforcement does happen.</p>

<p>I have the opposite idea after reading physiology books. The number I remember was 22%, for efficiency of a human being as a motor, driving pedals to create mechanical power. That's quite poor compared to an electric motor. And unless you want your fuel to be high-fructose corn syrup, your fuel is inefficient to make as well.</p>

<p>Do they claim enough reliability and peak power capability to delete the mechanical brakes? I know Brembo is working on electric brakes that would eliminate the hydraulic circuits and pistons. I don't know what they plan to do to make sure the electrical side is as robust as the split-diagonal brake system we've been using for 60 years or so.</p>

<p>> you can integrate all into one hub (breaks, bearings, gears etc) and it weights pretty much the same.<p>You would get to delete about half the mass of the half-shaft but otherwise you are cramming a lot of stuff into the wheel volume and it all has to survive living out there. Now your HV wiring and any cooling connections to the motor have to flex with the movements of the suspension and probably need guarding against rocks and other road debris. I think all EVs now have the drive electronics tightly coupled to the motors - now that either has to be separated or made compact enough to fit and rugged enough to survive a much higher vibration regime. We do have small amounts of electronics on hub assemblies today (I'm thinking of electronic parking brakes) so there is some precedent but  that circuitry is much less challenging than an inverter handling 100s of kW.<p>>no loss on diff<p>I doubt there's much loss from differentials in EVs. They don't have the bevel gear of diffs used in longitudinal layout ICE vehicles and mostly the gears in a diff don't move relative to one another (unless you are doing donuts!), so the whole cage mostly acts like a solid gear giving whatever final ratio.</p>
