Erm AC is far better than DC for long distance power transmission.

Conventionally Yes. but not in the case of the system now in use.
Ever heard of the Transpower HVDC line?
It was I believe the first in the world designed by the for runner to ABB.
Its the North island umbilical.

Don't worry about how it actually works and can be more efficient because few people actually understand it at Transpower as well (true story)

Is it owned by Jews?

Its a SOE no doubt as part of the nz population contains Jewish people so yes..... are you really that stupid. No need to answer that..................
The substations were in a Camen Islands holding company a while back though, but that was a tax dodge.
Any other stupid questions you have?
Or is there more premises to make you look like an idiot you want to visit.

I don't see any magic here.

He is using fuel in semi split cycle internal combustion / steam powered system.

Keep in mind a std motor is only 20% efficent recovering some waste heat and using it as steam would inprove the efficency, in comparison a steam boiler/ triple expansion steam motor is 60% efficent. They however are heavy and have a low performance per kg.

Folks have been water injecting motors for ages. One thing they do is clean up the emmissions espcially in diesels.

Keep wearing the tin foil hats, they really do block alien signals.

It is simpler for voltage conversion. DC is pretty much better for everything else; no syncing for generators, no power correction factors, no AC impedance/noise...

Yes and No
it requires a lot of extra gear as well but for ultra long distances it stacks up.
it is generated as AC then changed to DC then transmitted then changed back to AC again.
For the run of the mill Transmission line it does not.
Don't overlook it also was cheaper to build the towers. ie less conductors. Plus less cook straight cables

Wrong.

DC is fine for long distance transmission. We do it here and it works mint.

just up the voltage for AC lower losses.

are they still using mercury based relays for the cookie strait system?

from memory thats what i saw.....

interesting tech that.

Dunno, but it just got a massive upgrade with the second line.

i seem to remember it needed replacing quite a long time ago
a second line would be good for redundancy
not sure if the transmission line further up the nth island can cope.

been quite a few years ... I am sure some one can enlighten us

i found it quite interesting how the whole transmission system was setup and what plans were made etc. But i was only an observer for 5 minutes. Didnt know any detail but would be worth tracing all the transmission lines/power stations over NZ on the bike just for the hell of it. Theres a lot of history when you goto the power station sites.

Information boards quite often show how the dams were constructed and how developments from 20/30s affected construction. I enjoy that type of stuff - see how people lived and did stuff compared to today.

Most people drive/ride straight past those things.

Reckon it would be better with a Yoshi on the back.


Pfffff next they will be telling us they have invented flying cars .......

Its a conspiracy that they didn't try it with one on.
Also that we don't have them yet

For single point - for multi point not so much. Dropping the voltage through transformers is far cheaper/simpler than having a massive network of high current DC-DC converters.

First thing most DC-DC converters do is chop the DC into AC anyway.

When I worked high tension, I got to travel a lot of the lines through central and west. Spent a lot of time staying at the camps at the power stations. It's pretty cool.

I don't understand it well enough to disagree, just seems inefficient to convert it back and forwards given that DC is better for nearly everything electronic.

Heaviest consumers are motors/heaters. 220vdc would be nasty to have around the house - at least with AC you stand a chance of your muscles unclenchting.
