- sctb 8y agoThanks! We've updated the link from https://www.researchgate.net/publication/265403756_SINGLE-WIRE_ELECTRIC_POWER_SYSTEM_FOR_RENEWABLE-BASED_ELECTRIC_GRID https://www.researchgate.net/publication/265403756_SINGLE-WI....
- berbec 8y agoSerious question: was needing two wires holding us back?
- csours 8y agoPresumably, if you one use one wire, you will save half your money.
- benj111 8y agoBest case, I'm sure there are economies of scale.
- teraflop 8y agoNot only that, but if you have two wires at a high potential difference on poles, you have to be careful to keep them separated, even under adverse conditions e.g. high winds. Presumably, ensuring adequate clearance between a single wire and the ground is comparatively easier.

- ykevinator 8y agoCan someone help me understand the importance of this? Seems big but I just don't have the expertise to estimate the significance.
- rini17 8y agoExplanation using my half forgotten physics course: Apparently they are using the overhead wire as waveguide, with high frequency, using only its capacitance, thus avoiding ohmic losses. There are losses only from dielectric polarization, which they claim to be much less than ohmic loss in standard transmission.
- ykevinator 8y agoThanks for spending the time but can you give me the 3rd grade explanation?
- twtw 8y agoGets energy from the power plant to your light bulb without heating up stuff along the way quite as much.
- mdorazio 8y agoFor some reason I thought they had found a way to do DC current over a single wire. This is a way to get AC transmission using latent capacitance in the line if I'm understanding correctly. Still very interesting, but not what I was expecting.
- jpm_sd 8y agoSingle wire DC transmission is a solved problem. https://en.wikipedia.org/wiki/Single-wire_earth_return#In_HVDC_systems https://en.wikipedia.org/wiki/Single-wire_earth_return#In_HV... https://en.wikipedia.org/wiki/High-voltage_direct_current#Monopole https://en.wikipedia.org/wiki/High-voltage_direct_current#Mo...
- mdorazio 8y agoYes, but SWER uses the Earth as the return (as the acronym suggests), whereas the research paper title implies using only the wire itself.
- userbinator 8y agoI thought it was SWER (https://en.wikipedia.org/wiki/Single-wire_earth_return https://en.wikipedia.org/wiki/Single-wire_earth_return ) but in fact it's something closer to "radio current", as explained in this 20-year-old(!) article: http://amasci.com/tesla/tmistk.html http://amasci.com/tesla/tmistk.html The biggest problem I see with this is that it will cause a lot of radio interference --- a long wire with that much power going through it at the frequencies they use will basically act like an antenna.
- s800 8y agoQuasi-superconducting?
- baybal2 8y agoChinese BYD has been trying for years to make an overhead wires free trolleybuses with this technology. The main advantage is if you make it to operate high enough frequency, this should theoretically be safe to walk on, or at least safe to drive over. Given that it will soon be 7th years since they first announced that, and there is nothing they offer on the market, there might have been some showstopper issue with it
- twtw 8y agoTangential, but the formatting on this is awful. It's like a high school lab report - every equation is a different size and aligned differently.
- innagadadavida 8y agoWith such high power, how can you do maintenance work on these systems? With two wire systems, it is at least possible to avoid ground and short circuits.
- peter_d_sherman 8y agoExcerpt: "It was experimentally proved that SWEPS has quasi-superconductivity property for reactive capacitive current flow along the line even at high operation temperature of the electric conductor."
