Tesla Touts Cross-Country Trip, Aims For World Record

      But your local gas station doesn't need chargers, because you can charge it at home. The Tesla has a good enough range that many people could probably drive it back and forth to work all week, do the groceries, and still only charge it once a week (on the weekend, when electricity rates are low). At 300 miles, that gives you 42 miles a day. It won't cover everybody's commute, but a fair number of people should be able to make it through the week on that. In reality, the main place you need charging stations is out on the highway. Add them in at hotels and shopping malls for visitors to the city to use, and you could clear up quite a bit of land currently in use by gas stations.

      Nail, head hit. It would be nice to have multiple standards for charging stations, and it work across all cars. If we can do this with phones (MicroUSB), we can do this with cars, except with some caveats:

      1: Circuits may vary. One place may have a 15 amp, 120VAC circuit at best. Another place might have an 80 amp circuit to support higher chargers, with a 50 amp subpanel coming from it to handle current charging needs.

      2: The charger would need some safety features, If someone stuck a fork in a charging cord and got even a tingle, the lawsuits would be flying. Most current chargers are goof-resistant, but this is definitely an issue, especially in the US where I've seen workers stick two straightened clothes hangers into an outlet, then use alligator clips between those and the prongs on a plug.

      3: Patent neutral. This needs to be a benefit for everyone, as vendor-neutral chargers will help every player in the market.

      4: Low voltage failsafes. US power can be dirty [1], so it should either downshift or stop trying to charge altogether if it gets under 90 volts.

      5: High voltage failsafes... Same reason. Just in case someone hooked up 120VAC to 240 or vice versa. This isn't an issue in Europe and the rest of the world, but there are a lot of RVs killed each year by plugging into a 240VAC dryer outlet which is almost the same shape as a 30 amp, 120VAC receptacle.

      If we double the batteries, we now have 800km worth of charge, but the carsphere also weighs 25% more. This results in an actual range of 800 / 1.25 or 640 km.

      Now, since I've done the completely fictional numbers, I've changed my mind about getting real numbers.
      A Model S allegedly weighs 2108 kg with no passengers. The larger range option allegedly gets 500 km to a charge, and a forum post that I can't track back to a better source claims that over 1500lbs are battery.

      For convenience, I will round total carmass to 2200 kg with driver, batterymass to 680kg and batteryrange to 500km.
      Using the same process of math as above, this suggests that adding another 680kg batterypack would adjust the range from 500km to 760km. More than a 25% increase, but I'm not dealing with real-physics either. In a world of ideal math, doubling the battery increases the distance by about 50%.

When filling stations first showed up, they too were isolated points that couldn't be linked by the range of the available vehicles, then got strung out on transportation corridors, and only now are ubiquitous. Having a look at the rollout map, the infrastructure will cover a lot of the US's transportation corridors by the end of this year.

      As for what happens when $40k electrics start rolling out - I'm not terribly concerned. The number will be small to start, and the number of vehicle trips that would actually require a supercharger station is vanishingly small. I doubt that the utilization of the existing stations now is anything above 5%. You can bet that Tesla has realtime statistics about utilization, and probably even the wait times (i.e., how many cars are queued up), and can adjust their rollout accordingly.

Would I have more energy than I started with?

      A sedan needs about 20-25 hp to maintain highway speeds on level ground. This is mostly aerodynamic losses (there are smaller losses due to rolling rubber tires, friction of the axle, etc). Going with the lower figure, 20 hp is about 14.9 kW.

      A 50 gallon water bladder would weigh about 189 kg. To extract 14.9 kJ of potential energy from it each second would require 14900 J/s / (189 kg * 9.81 m/s^2) = 8 meters/sec altitude drop.

      So no, even if your regenerative braking were 100% efficient (thus the energy to push the car up the mountain is completely recovered during the downhill trip), 50 gallons of water isn't enough to overcome air resistance to move the car forward at highway speeds for the trip. It's short by about two orders of magnitude. The concept works for undersea gliders because they're content with moving at less than 1 m/s, which keeps friction losses minimal.
