this story in not true, we have losses in every system , heat behind your computer comes either way even if u had dc direct do it. transfering ac to dc with good coil makes no losses maybe 0.001%. any knowledgeable enginer will not agree with this
why not make out appliances to receive ac current? why semi conductor in alot of stuff? to makes money of course!. It showed up 50 years go, before that 50 years there was no semi conductor, and everything work with the ac power. The more efficient to go, is to take out the semi conductor!
It's just dumb to present this as a competition, cuz there is none, at least there shouldn't be one, cuz AC & DC r each perfectly good for the tasks they're supposed for. The best would be to combine them. There's no need for dc everything, I don't see the point of dc light bulbs. (and light bulbs should also be used in combination, incandescent & fluorescent, that push for fluorescent in EU is totally ridiculous)
BullShit, There are many flaws and flat out lies to this video. This is possible if every home was generating their own electricity. Because you need a substation every 2 miles to maintain a strong DC current. Laptops/anything with a battery run off DC, the converter is in the charger not in the computer, the heat from a lap top is from the integrated circuitry. Answer to the problem, Don't plug your solar panels into the grid, use it for charging batteries.
The problem with DC current is that in order to carry high currents voltages the power line would have to be very thick or else the power line would overheat and be a very dangerous fire hazard and would lose a very large amount of current and voltage along the line.
The main problem with DC is that it can't travel far without huge power losses. I'm sure theres some complicated way of using transformers with DC, but DC doesn't work in normal transformers. So why not just keep the AC because it works fine?
@djd1993 "The main problem with DC is that it can't travel far without huge power losses." That's a completely incorrect statement. DC is better for very long distance transmission, both in terms of energy loss and component cost. Look up "DC Intertie." DC does not use transformers. When changing voltage levels in DC, the term used is "conversion," and "converters" are used.
@djd1993 Well, since you don't care, it would be a fair gesture of decency if you could compel yourself not to preach ignorance about a subject you have no interest in, and little knowledge of.
I've thought about this myself, and one thing that occurs to me is that stuff runs on different voltages; if you use voltage splitters everywhere, you are losing efficiency that way too. You could use a switching power supply to convert, but that goes back to DC-AC-DC again.
lol i'm looking forward to Hit Dc whit my system here ... i'm pretty sure lots of ppl are already doing it. those who say it's a lost of time just don't understand. Electricity is not that hard to understand .... and AC had his place back then ... for long distance travel, now we have the technologies to get our own power and DC is perfect for short distance travel.... this video dont tell ppl to change there rig right away, it's telling ppl Hey ! you got an oportunity to save 300 $/ month :D
Ah, the laptop brick is hot because of the rectifyer bridge.
YEAH RIGHT DIPSHIT!
You didnt even mention the pros and cons of DC vs AC, the hazards of AC, the problems with transforming DC etc.
Imagine if you got DC mains at 110volts, to make that into a useful 12v in your laptop you'll need to first convert it to AC, and then reconvert it to DC to make the chips happy.
And ben frankling in the beginning? Yeah. You didnt even get that right.
@fscii Power has to be conserved. If you have an AC source that drives 400W to the computer, and the computer requires a DC supply then there is a conversion. In this conversion there is a loss (address in the video). But power has to be conserved. That lass is in the conversion process. If you are using a linear rectifier it will be there, if you are using a switching supply it will be there. You probably won't see more than 380-390 watts in the computer, because some was lost to heat
@fscii Power is NOT amperage. If you have a set voltage (like 60hz 120v RMS here in the US) you can compute the real power simply by knowing the voltage and load specifications. A motors output is in power. A 200watt dc motor or a 200 watt ac motor both output a little less than 200 watts (you have to assume it's only 85-90% efficient). so a 12v 200 watt dc motor is going to pull 16 amps. A 200 watt AC motor on 120v RMS is NOT going to take in 16 amps.. more like 2A depending on its capacitance
@MaN1aC666 So your saying DC power transmission is more effective than AC? What have you tried on your solar panel? what have you tried that "makes him right"?
Tesla was killed over this, he found a way to give free energy to every one, but a few men decided that we needed to pay ! ... so here we are, that was the conspiracy ! But ppl got more education now so pretty hard to stop
Apples and oranges my friends, this is like saying, you need to slow down flow in a fire hose because you can't drink from it, ac and dc do different jobs, ac power is for long distances and dc is for control, some jobs are better achieved with ac and other jobs dc, you can't generalize and expect to be correct everytime, and I love how edison didn't invent dc yet because he threw a fit about it he gets credited in a way for its use.
@protogenius "AC is for long distances" - Do you not understand this video is targetting localised power generatation ? ie: not long distances ? apologies if i misunderstand you !
@jezwah You have pretty large losses with DC even across a house... Especially at the voltages our devices run at (1.2, 3.3, 9, 12, 24). Those lower voltages of course could be regulated and transmitted at higher voltages but you are allowing losses by doing stuff like that which kind of defeats the purpose or the intended goal. You have a losses in EVERY regulator, even a DC to DC loss. Say a devices requires 12v and 6 amps. Transmitting at 50v means the regulator consumes (50-12)*6 = 228 Watts
@protogenius Wow thanks. I didn't learn a damn thing from the video, it was all just an ad. But I read your comment and learned what I came here to learn.
@mackhaio5 Cool - how do you power your fridge? Computers? Lighting? You have replaced all standard housing power supplies and lighting systems for DC equivalents?
@chadbobb Lighting systems could easily be changed over to LED's, not only are the much more efficient, but they are pretty much better in every way, other than the price of course. They never burn out (pretty much never at least) And as stated in the video, most modern tech uses semiconductors, which need an AC to DC conversion anyways. Its not impossible, its just a huge change in how the energy grid would have to be set up. The only reason we used AC is cause DC cant travel very far easily.
@OrangeTang666 Problem is that you can't run a transformer on DC.
Your microwave oven? Yeah, That won't take DC.
And if you ran your entire home on 12volts (you would still need transformers, your computer uses a lot of different voltages, 3.3, 5, 12, 24volts) you would end up needing about a dozen strands in each power cord for the appropriate voltages.
Now to the issue of transporting low voltage. You would need wires 50-1000 times thicker for the same power...
Bullshit. It takes only takes 4 diodes and a capacitor to convert AC to DC. Then you need transformers and rectifiers to bring the voltage coming through out power outlets to a voltage it can work on.
@gandalf87264 transformer comes before the diodes and capacitors(we generally step the voltage down then rectify it). There are still efficiency losses through all of those components. Hence why your laptop charger gets warm.
We can never eliminate AC. Our manufacturing and large scale systems in this country require A LOT of power, generally in the form of 3-phase that is unmatched by home generation.

Nextek's technology is about DC Microgrids in buildings, not transmission. DC power systems in buildings allow for solar PV and batteries to be used as a DC source for DC loads like everything electronic.
@thebteam300 thats true for long distances and thats one of the reasons Tesla won the "power-wars" but for powering individual building, it is MORE efficient to power them off DC
@powermaks Even running low voltage DC across a building is highly inefficient. And there is no point in running high voltage DC, as all of our devices use between 8 and 24 DC volts - and the regulators required to step down high voltages would probably carry similar losses to our current method of rectifying AC sources
@chadbobb this is why we have transformer .... 12 V 24 V 48 V ... depend on the need more you need more voltage you put, yes it's a big change, pout 2 X 75 Watt panel on your roof, 2x75=150 Watt try running your fridge in your home ... but your fridge is around 120 V 15 Amps = ... 1800 Watt or more ... now check on the DC side 12 V 15 amps = 180. mmm i see my bill and i'm thinking alot right now :) are you ?
@MaN1aC666 What's your point? Most refrigerators use between 200-400 watts (AC power). If you used a DC motor instead, that number wouldn't change - Power=power, and a 200 watt DC motor is virtually the same as a 200 watt AC motor (though they function differently). Your logic seems to assume is that the only important detail is amperage, but amps have nothing to do with it. We care about power - to turn the compressor(in the fridge) we require power not amperage. Same for all electrical devices
@Serostern Your average 20 cubic foot fridges uses 420 watts. Not sure where you are getting your numbers. It might average 120 watts since it isn't on all the time. Unless of course you meant 120 volts, or you are just trolling.
@Serostern Ok I agree it probably uses 100 watts on average... but I was talking about the instantanous power... The power it uses when it is actually on. The compressor turns on and off, so when on it uses ~400 watts. When off if uses ~0 watts (just a tiny bit for the light bulb or maybe a temp sensor/LCD if fancy and new).
So yeah, if it is actually "running" 1/4 of the time (sounds about right?) then averaging 100 watts is probably accurate. Why a 230v fridge? sounds industrial
But Until Now Most of the Inverter Around the World Still Can't Pass The RCD Most Inverter Are Problem With RCD Safety .I Have an Experiment For About 12 Years Already until Today About 16 Inverter Experiment Most Of Them Are Not Pass Home RCD ???? It Was Unsafe.
