A few people out there have experimented with constructing their own replications of the Edison battery, which is an amazingly durable battery design. Thought I'd start this thread for info.

Edison was an engineer and a business man, pure and simple. Tesla was a genius. Therein lies the difference. Both men made their mark. Edison argued "The gasoline engine is dirty and polluting". His batteries were made with utilizing a minimum degree of corrosion and lasted for 20-50 years. Some are still working, 100 years later! For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses. For underwater power cables, HVDC avoids the heavy currents required by the cable capacitance.

Everyone, and everything has it's place!

Hi ALL

I agree with you Mag you can't drag that biscuit through the gravy with out a lot of resistance = DC But rolling the biscuit is like AC it goes through it much easer LOL

LOL at MAG but i am with you on this when it comes to Edison -.-
Soooo lets get down with the volta pile instead, think a post on that will be good...anyone :))

LOL at 49er, nicely put...very nice :)

It's proven. Both EHV (sinusoidal) and HVDC are employed now. It depends on the application.


"Canada's many economically attractive hydro sites are often located far from their markets. Canadians have had to pioneer new transmission technologies such as the world's first 735 kV transmission line, which is state-of-the-art in extra high voltage (EHV) alternating current and high voltage direct current (HVDC)."

"In December 2010 Fingrid and Elering, awarded the contract for the EstLink 2 Converter Stations, using HVDC Transmission System. The system, with a transmission capacity of 650 megawatts at a DC voltage of ± 450 kilovolts, will increase the capacity for transmission between the Baltic and Nordic countries from 350 MW to 1000 MW. It will also make the power supply more reliable. The output between the two stations will travel over a 14-kilometer overhead line, a 145-kilometer submarine cable across the Gulf of Finland, and a 12-kilometer land cable. The customers are the Fingrid power utility in Helsinki and the Estonian power network operator Elering, in Tallinn."

Hey Kcarring
Even though I have no love for Edison, Im with you on the battery I think its at least worth having a good look at. Ive already have a few ideas to boost the voltage in a single cell and still keep it small. Just need to find a source for the sulfates for plating.

i guess someone found a way to make the long distance DC doable, but im not quite sure the reasoning there.. nor do i understand how, in any fashion, a long distance DC transmission could be considered less costly and more efficient, but maybe thats not in their agenda.

far as batteries go i think its all about the super and ultracapacitors. wish i could make some quality home-made ones. when it comes to a battery of any kind its just a matter of being able to afford and construct the various metals that give the best reactions and what not, but its still not adding up to the quality of a good capacitor. i feel like regular quality batteries are all over the place to be found practically for free as it is. thats probably why id never take the effort to make a battery, with about $20 bucks worth of junk yard batteries to restore, and about $50 bucks of sulfuric acid mix you can have yourself a 12v 450Ah supply bank. we are so far from phasing out these obsolete batteries we might as well use them like hotcakes for free when people throw them out.

@Mag

I'm guessing it's not far off Tesla technology really. So don't blame Edison for it, blame Tesla lol... The funny thing is, folks like PL rant on about better ways, well yeah, there are and their used and yes it was probably Tesla inspired, get with the program LOL. High voltage, high Frequency Pulsed Current, thinner wires, less capacitance. I guess it depends if you wanna believe the whole "longitudinal wave thing, etc. etc". Fact is, everyone screams "oh.. there's a better way". Yeah. And it's been in use for a while now, read the news. They don't call it what Tesla called it, because if you look at it on a scope, it's pulsed high voltage forward biased energy, with a small AC component... it's not "just AC" - and they have not adopted the term: longitudinal wave, because the scope merely shows a Hertzian wave... Now that's not to say it is exactly the same as what Tesla did / used, of course not - but it's very close to what WE play with, when we replicate Tesla experiments NOT using a true spark gap. Or that's how I see it anyway. In any event, it is far less lossy than long distance transmission of pure AC, and it uses only two conductors for three phase even, instead of three. So the wire costs are less. Anything over about 60 km, it becomes an option, and under, AC makes more sense. In 1000 KM transmissions, for example, it is the ONLY way you can do it, really. (meaning no substations in between)

It's basically what we all play with, on a grand scale, essentially.
