Your battery would need to be 10x as large... if you're using resistive heating, which turns 1 J of stored electricity into 1 J of heat.
But if you use a heat pump, whcih turns 1 J into between 2 J and 5 J of heat, it brings the battery size down considerably.
Also consider that your propane heater will not have efficiency of 100%; it will turn 1 J of gas into 0.93 J of heat (in the house), or probably less.
There are certainly issues with batteries, but the drawbacks are not quite as large as you're suggesting here. In some circumstances, such a battery bank may be quite reasonable.
Additionally, there are people with compromised immune systems that can't take the vaccine.
In this case, no, that is not correct. The RNA vaccines are not weakened viruses; they cannot possibly infect you, regardless of how weak your immune system:
“It’s only one strand of RNA for making a part of the virus – not the entire virus – and it’s not infectious,” says Rob Kozak, a scientist and clinical microbiologist at Sunnybrook Health Sciences Centre in Toronto. What’s more, the other leading vaccine candidates don’t contain infectious agents either, “so there is no risk of these vaccines making you sick with COVID,” Kozak says.
+ Courses may be easier as staff over-compensate for remote learning issues
You label this as an advantage; why?
If easier means you learn less, that's not an advantage. You should be studying to learn.
If courses really are easier, employers will learn that those who studied during COVID-19 are less skillful, and not want to hire them, or pay them less.
Creative Commons *is* a copyright license.
This is how you copyright a work: write it. Done!
Now no one can distribute it without your permission (except as allowed by fair use). You can give them permission to use it in certain ways using a new or pre-existing license, like CC (or GPL). There is no "conflict" between copyright and creative commons; quite the contrary, CC depends on (C). The GPL does too, as RMS has pointed out more than a few times.
Compare the size of the market to the size of the market for various other systems. There were 17 million Commodore 64 machines sold. I suspect there are easily this many people with open source desktops in the world; there are around 10 million users of Ubuntu alone. Does the author mean to say that the Commodore 64 was unsuccessful, was itself dead on the desktop, for having a mere 17 million users? It seems unlikely.
Being the sole desktop option is a hazardous place to be. If you believe in capitalism, you should prefer a mix, you should prefer that users (at some level, potentially corporate) decide which system to use.
I use GNU/Linux: Ubuntu on the desktop, Debian on servers and sufficiently high-end embedded systems. That's not about to change. I'm glad others are concerned about converting people, but only so far as it causes them to make better the software I use.
Almost anything derogatory you could say about today's software design would be accurate. -- K.E. Iverson
