Good. They not only suspended his account, but also removed his last video where he encouraged the protesters to go home and be peaceful.
Removal of that video on all platforms affected the public opinion enormously.

Well, the problem with the heat pumps in my house, is that near or below freezing temperatures, the outdoor unit has the tendency to freeze over, then either it has to run its resistive heater, or intermittently cut out and blow some cold air inside. It's rather uncomfortable.
I'm not sure you can get away with a design that has to sporadically turn itself off, and melt itself down in an EV.
Heat pumps on cars can go well below freezing without any issues.
Let’s have restaurants raise prices to cover employee salaries, and make it illegal for them to ask for tips. Customers who want to tip need to do so without solicitation. (Not sure how this would work with credit card terminals though).
An obvious question is: what were the 60 minutes team doing on this exact ship? There is got to be more to this story.

Having pi^2 = g would annoy me a bit as g is fundamentally a measured value. Depending on the required accuracy of the calculation, you can't even use the idealized value.
We simply wouldn’t need “g” and would say that acceleration due to gravity on earth is sqrt(pi).
When these articles talk about “EVs” almost all the time what they REALLY mean is “non-Tesla EVs”.

Bitcoin will never go to $0 because if it ever got to $1 I'd buy all 21 million of them. And there are lots of people like me.
Not if the algorithm is cracked and the supply of bitcoin increases. It’s possible for bitcoin to go to zero. Shouldn’t happen, but it can.

Like making anything last, don't operate at the limits of its envelope.
* Limit max temperatures
* Reduce maximum currents in and out
* For lithium batteries, limit peak charge to 3.92V, do *not* charge to over 4.1V or 30degC
*edit, when using a cheap intermittent high current device, like a hand vacuum, apply a duty cycle, like 30 seconds on, 10-30 seconds off to prevent the internal battery pack from getting too hot. These kinds of consumer goods have the smallest battery pack that will outlast the warranty.
I really wish battery charge profiles were codified in QR codes on the modules themselves (besides existing on an I2C bus).

3.92V is very conservative, that is a good voltage for long term storage even. It should be safe to charge to 4.05-4.10V regularly.
For comparison, Teslas do not require purchase of their software for basic maintenance, the service mode that is accessible to the user is amazing, has so many diagnostics tools available for free.
Oh and by the way, from my experience Teslas don’t ever need brake pads replaced unless you are taking the car to the track. I suspect the same is true for most other EVs.
