you mean they weren't taught my TA's?
It's split up into lectures by profs, and discussion sections led by TA's
It's supposed to work by having profs lecture generally on material (usually such lectures in my school are 1 or 2 hundred students) and then smaller discussion sections actually have you do practice problems
In reality, I had a professor spend the first hour of a 2 hour lecture talking about her research with lasers or some shit. This was a course mostly focusing on thermodynamics. Set the tone for the whole semester

> Powering a whole house with a generator (or Tesla) while the power is out is dangerous. If there is a lineman working nearby, the energy can run through the lines coming from the house and still deliver a shock.
That's why automatic grid isolators are a thing. It is evidenced by the fact that the neighbouring houses are dark. If they weren't isolated, they'd either get lit up, or the powerwall/generator would get overloaded and no one gets lit up - except the lineman
@Agent Smith I see what you're talking about - they speak about installing the switch that isolates your house from city power while you're on the generator. I'm sure other such devices exist and are being implemented into infrastructure. I was more talking about the scenario when a dingus who doesn't know about such safety measure decides to try and do something that results in the dangerous backfeed
My knowledge could also be out of date on the matter
I think the one they show is a manual one, but I've seen isolators that will only allow a house to be fed by one source, using electromagnets
Interesting. Do you have any idea how widespread they are? I doubt these come standard
plug the genny in and electromagnets disconnect the grid kind of thing
haven't heard of it in Australia, but I've seen them in US and UK videos
Does seem like the sort of thing to have if you plan on powering the house in a storm.
Most I've been a part of on that front is plugging the coffee maker into the genny while the power was out
I'm pretty sure these powerwalls have isolation built in
they probably also have phase sync like UPS's and grid-tie inverters do
Oh jeez, I hadn't even considered phase sync
That would also be an issue
Out of curiosity, what's coming out of your wall in Australia? I know Europe and U.S. are very different.
240v
my UPS says 231v
Do I need to invert the phase to power a device made in the U.S.?
no, lol
ac here is 50Hz tho
huh
if you have like a iphone charger, they run 90-240v @50/60Hz
Japan is 100v
that's why it goes that low
I guess every continent needs to have its own special power specifications
America has "split-phase" 240v for stuff like ovens, dryers and furnaces. I get it, but it's retarded cuz it was a work around that needed to be invented cuz the US gov made standards to favour copper miners when the standards were being invented
yup
short sighted bureaucracy
though I'd rather deal with bureaucratic 240VAC than try and take people who talk about free wireless energy seriously
does Germany have single-payer healthcare?
In my sate of NH we have a Meals and Lodging tax. We don't have other taxes though like sales tax
We should tax politicians for all of the hot air they generate
heh, agreed
