  • problem is a phone only works if you have it on you. Grandma falling often is a case where she doesn’t have a phone (often grandma in this case is in mental decline and wouldn’t think to use the phone if she had it).

    A privacy respecting device that can hear “help” and general cries/grunts to get help when needed is what the world really needs. This is much more complex than the ask, but it is the real need here. For me what the OP was asking is enough, I just need to inform a kid in a different room dinner is ready.


  • algae releases oxygen, but then consumes the oxygen again latter when the energy is needed. There is just a surplus that isn’t consumes - everything that makes up the cell isn’t recombined, also oils and such may result as well. Sometimes this surplus rots/burns thus converting back to CO2, but other things can happen (sink to the bottom of the sea where there isn’t spare oxygen to recombine with). Not all recombining is perfect either, sometimes you get coal as a result. The vast majority is recombined, but there is a lot of algae and so just a little bit of difference makes for a massive amount that isn’t. (not near enough to make up for all the fuel humans are burning - but overall the earth seems to have been slightly net negative in CO2 before humans started burning fossil fuels for energy)












  • Yes, but for most people the difference doesn’t matter. BMS systems (see other reply) minimize this, and most people typically are doing a much slower charge at home the vast majority of the time. If you really are driving across the US constantly and thus always fast charging for everything it will shorten your battery life. However you will still likely trade in the car before this affects you, and the new owner will note the reduced range but will accept it as a good trade off for the lower cost car.
