My question here is if I had mini grid and I used DC current, does that
mean that all appliances I had need to be specially made to use DC – is
there anyway around that? Since all appliances are made to consume AC
voltage I doubt they would work with DC voltage, or am I wrong?

There are many suppliers of DC appliances. In fact, there is an entire
house running on DC

i don’t see why we just go with both and be done with it, both of them have
their advantages and disadvantages so why debate over which one is better?

How about starting with advantages & disadvantages of AC vs. DC?

Actually Franklin made up the kite thing, Never happened. He did actually
do studies about static being electricity.

It seems like edison and JP Morgan did tjis ad to destroy Westinghouse and
Tesla HAHAHA

Ok when I was doing some studying of DC and AC the book mentioned that
conventional electricity is wrong, meaning DC was the wrong way and AC was
the right way stating that all our books are designed for the old
conventional method. So now I am definitely confused. I personally like DC
because it seems a lot easier to understand and work with.

Man, you ain’t gonna waste the electricity in appliances, but in the very
wire which carries the DC current.

Ok you sold me as I recalled back in the day they fried people and animals
with AC to try to get the point across and that didn’t even work so we need
more proof lol . thanks a thumbs up

Hardly any power is lost by rectifying, what dissipates in traditional
electronic appliances is low-grade stepdown transformers and stabilization
of the rectified voltage. Even this isn’t ALL of the heat you get off the
back of the appliance, which indeed is most of the power it draws because
little of it becomes any other kind of output so what else but heat does it
wind up as. The main reason for AC was the high efficiency of well designed
transformers and partly advantages of AC motors

Specific examples? (the giant Tesla coils on the north & south poles don’t
count lol)

Actually DC is much much better than AC in long distances since it is not
effected by the lines inductive behavior. As far as I know the problem with
DC is the lack of switchgear and transformers. Other than that it is
preferable to AC. Switchgear and transformers are huge issues though. Could
you tell me more about the cost of DC?

DC is far more efficient to to use in a higher voltage”off grid” systems.
It cuts out the need for an inverter and the loses that come with it. The
main advantage with AC is that everything is geared around its use and most
induction appliances are main frequency driven. But this can be over come
if you have the know how. In reality, the thing that holds back progress
and efficency is that most of the worlds population are consumers and will
never make the world a better place.

Designing for a region cold & often dark in winter, with sporadic wind,
don’t sell wonders of PV & wind turbines to us! We have coal, wood,
agro-waste, woodgas. (See wood gas if you burn wood!) We want separatist
church community off grid. (Some Mennonites now use their OWN off-grid
electric; won’t pay electric corporations. Seek to make DC generators,
motor, appliances! Amana started rural!) We (separatists, not greens) need
DC standard voltages, plugs, wiring, to make appliances for many!

Devices require DC at different voltages. others produce DC at different
voltages. Waste of time to think of all DC systems unless we start talking
of multi voltage systems. \ac is here to stay. DC is good for high power
long distance transmission (Giga watts and megavolts) as it uses insulation
more efficiently. But that is a different story.
