The 'what is safer' question for DC and AC at the same effective current and power has a mixed set of answers depending on conditions. For instance, DC is more likely to cause your muscles to contact and not let go (bad), but AC i

Those harmless 9V DC cells can do a lot of damage if you use them right.

You got super lucky.

I think the real reason is because battery power didn't have to be converted twice to be able to run the gear in case of an outage, so you'd get longer runtime in case of a power failure, and it saves a bunch of money on supplies
786.
by jacquesm 7mo ago
Yes, and that tiny little difference can cost you a lot of expensive gear if you run it off the battery and plug in a serial port or something like that. You'll also learn first hand what arc welding looks like without welding glass.

Agreed, for the IEEE to go down this route is more than a little weird.

Not going to happen. For the same reason that the US never converted to a higher domestic voltage even though there are many practical advantages. The transition from one system to another at the consumer level would be terrible, even if th

Hm, yes, you are right, I must have been reading on submerged cables, but it's a while ago. The devil is in the details here, AC tri-phase cabling can not easily be re-purposed for HVDC purposes because you only have a pair of conducto

Neat. Congrats on launching two interesting projects and looking forward to the third.

HVDC is a miracle of modern engineering that could not have been done in the days of Tesla. It removes several sources of losses that otherwise would have turned valuable power into heat. That said, it isn't without drawbacks: the cabl

> With a bunch of AC microgrids joined by a DC major grid, you can completely sidestep that problem. Not necessarily. Big local consumers will be large relative to the microgrid, which will not have a lot inertia. This is one of the thin

Great idea. I'd love for there to be an 'open ended answer' without giving multiple choice options. Like this they are not debating the question itself but the validity of the possible answers and the real answer to the quest

Good questions!

I think it would be fairly easy to prove or disprove that 'AI as it is today knows more about any subject than 99% of HN'. But knowledge alone does not translate into intelligence and that's the problem: we don't have a

And not without sloppy marksmanship, russia, the systematic destruction of education and a hundred other reasons. But in the end people actually had to go out and vote for him and that's the part that I have a problem with.

I wonder how many 'ideas guys' will now think that with LLMs they can keep their precious to themselves while at the same bragging about them in online fora. Before they needed those pesky programmers negotiating for a slice of th

Anybody on HN that didn't know that you can build a machine from parts or isn't capable do doing so is probably on the wrong website ;)
