  I’ve had a few different First Aid courses and the instructors all have slightly different reasoning. One argument for compression only is potential for passing disease mouth to mouth, the newer courses tend to teach this because sometimes people that don’t feel comfortable doing rescue breaths will fail to do CPR at all. Another is that in cases where you’ve witnessed the event, the blood is already fairly well oxygenated and if medical help has a good response time the benefits of breaths are minimal. The first is more about compression only CPR being better than nothing, breaths are still advised where the rescuer feels comfortable doing so. The second is pretty situational.

  Even better would be if more devices used the lithium ion cylindrical cells. Higher power and energy density, while also being a standardized form factor that can be switched out as needed.

  This is right. A proper system has a transfer switch that prevents back feeding the grid if it’s down. There’s also a safety aspect in that supplying power to the branch circuit in this way bypasses the overcurrent protection, so one could potentially be loading that circuit with 5 A on top of its rated load and cause significant damage.

  If a person wants to offset their electricity at this small scale, better to have it powering a shed or charging power tool batteries. Won’t get as good a return, but you’d never get a return on a permitted grid tied system at that scale either.
