B) If trees take out the power lines, you'd be stupid to waste your limited battery power just wasting time on the internet, you might need it for an emergency.
C) What makes you think cell phone towers are immune to power and connectivity losses?
You do want to do two other things. 1) Keep that install disc, and make sure the kid knows how to install Windows himself, plus install his games himself. I think WOW and probably LOL are both cloud-based saves so wiping the HDD is no issue. Reinstalling Windows is generally 1/4 the time and hassle of actually fixing a malware problem.
2) Let him know that he is only likely to get viruses doing things he shouldn't. Drive-by downloads on legit sites are rare. Drive-by-downloads on warez, gold sellers (for WOW), and porn are a lot more common. If he is going to do that stuff (you can't stop him) at least make sure he knows that those are dangerous sites. If his computer is acting funny after visiting one, and a reboot doesn't fix it, then wipe the install.
If you're getting 400-500% efficiency, this means you're inventing energy as you get 100% max. Any more, any more and you're opening up a hole from another dimension to let energy in. I want to know how to do that.
He said it's a heat pump operating in heating mode. It is quite literally importing heat from someplace else - usually the outside of the house where the external unit on the A/C is. He is using one unit of energy to run the pump to import another 4 units of energy from outside the house - thus 4 units from 1 unit, 400% efficiency. It's just outdoors, not another dimension.
If you didn't have to work so hard, you'd have more time to be depressed.
