The bus lines in the US tend to be spread out enough that riders often have to walk a long distance anyway as many/most destinations are far away from the route itself and would require substantial non-bus travel even with infinite bus stops along the route. Given that reality, the density of bus stops along routes seem inefficient for a very small real world improvement.
I got two Tesla Powerwall 3s partly because I thought the software would be better. Instead, they are extremely buggy and the software has poor functionality. Many of the features are broken. The product feels like a prototype. Grid charging is broken and many of the features related to it don’t do what it says in the app. The batteries regularly do calibration cycles where they dump their entire charge and then stay at 0% charge level for at least 24 hours. When I first got them about a year and a half ago they would do that about once every two weeks, although they have reduced the frequency. I’ve also had issues with them turning on their heaters when it isn’t even cold and draining themselves. You get little to no insight into their operation and need to contact technical support for any little issue. They crash and do a hard reset and shut off the power every so often as well.
Paying a tesla tax to waste extra power AND not be sure they'll be charged in the event of an outage - quite a combination! Thanks for putting this review out there - its a good counterpoint to all the hype!
Yes, and the reality is that any of those would require a fairly large constellation of satellites. I guess the play is that many large constellations of satellites will be launched.
On top of that, despite huge investments of both time and money into both areas, seemingly rivaling competitors, Tesla does not seem to be anywhere close to a market leader in either segment. They have to both prove the markets and that they can compete in them.
To some extent. There are limitations on the technique, including, but not limited to, not determining the relative concentrations and not detecting all components. The WSJ article actually links to an older Wired article about doing gas chromatography and mass spectroscopy on WD-40 and the results: https://www.wired.com/2009/04/st-whatsinside-6/
The default setting just moves the coast point to a slightly depressed accelerator. This is because EVs typically have lower drag, so this behavior mimics a higher drag vehicle. If you use the accelerator to achieve the desired speed, you will coast when possible. You can also monitor the display to see the coast point. My 2013 plug in hybrid only supports this style of operation.
Modern EVs have easy adjustment for this. The Hyundai/Kia EVs for example have shift style paddles for adjusting this on the fly which includes a mode for regen only when depressing the break pedal.
The Hyundai/Kia EVs do not have a mode that only regens when pressing the brake. The best you can do is limit the car to 2kW of regen braking when not touching the accelerator. You can't disable it entirely.
It's true though that using this mode will extend the life of your tires.
The blog says that in regard to finding bash with env. My reading is that it does not make the same claim regarding finding go with env. bash is commonly found at /bin/bash (or a symlink there exists) as it is widely used in scripts and being available at that path is a well known requirement for compatibility. Go does not so much have a conical path and I have personally installed it at a variety of paths over the years (with the majority working with env). While I agree with the author of the blog that using env to find bash may or may not improve compatibility, I also agree with the parent comment that using env to find go probably does improve compatibility.
