This limitation makes it impractical for true long-range power transportation, such as powering a quarry 50+ chunks down a railway, as the power would drop off completely well before it would reach the quarry. The railway chunks would all ready be force-loaded by Railcraft anchors for the quarry+railway to be functional to begin with, so why not have IE power cables that can bridge the gap?\r\n\r\n\r\nIRL, the higher the voltage the less power loss occurs, exponentially. \r\nThis can be modeled with `f(V)= R^2/V^2` when V = input voltage and R = cable resistance\r\nThat is why power mains irl are so high voltage, because its cheaper and more efficient.\r\n\r\nBased on how you are currently modeling power loss over distance, the power throughput (RF/connection) is not even put in consideration, you are currently using a linear power decay model. the only factors that make any difference based on what i can derive are the max cable length and the linear resistance value. \r\nYour current power model can be represented as below:\r\n`ΔP=B-max(min(B*(X/LR)))` or\r\n `ΔP=B-max(min(X/LR),B^2),0)`\r\nwhere P = output power, B is input power, X is distance, R is cable resistance (a fixed linear value),and L is max cable length (per connection)\r\n\r\nSo why is it that HV has a significantly higher power loss, twice to be exact, than MV if it is intended for long-range transport?\r\nHV travels 320 meters (20 chunks) at 100% power loss\r\nMV travels 640 meters (40 chunks) at 100% power loss\r\nThese numbers are based on default config values and experimentation to validate the functions stated above. MV can transfer power over the same distance that HV cannot transfer any.\r\n\r\nBy adding an EHV tier of power, one designed only for the long-range transport of power (20+ chunks) IE would become even more practical for big bases and big builds alike\r\n"},"comment":{"url":"https://api.github.com/repos/BluSunrize/ImmersiveEngineering/issues/comments/136076895","html_url":"https://github.com/BluSunrize/ImmersiveEngineering/issues/362#issuecomment-136076895","issue_url":"https://api.github.com/repos/BluSunrize/ImmersiveEngineering/issues/362","id":136076895,"user":{"login":"theunkn0wn1","id":3110986,"avatar_url":"https://avatars.githubusercontent.com/u/3110986?v=3","gravatar_id":"","url":"https://api.github.com/users/theunkn0wn1","html_url":"https://github.com/theunkn0wn1","followers_url":"https://api.github.com/users/theunkn0wn1/followers","following_url":"https://api.github.com/users/theunkn0wn1/following{/other_user}","gists_url":"https://api.github.com/users/theunkn0wn1/gists{/gist_id}","starred_url":"https://api.github.com/users/theunkn0wn1/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/theunkn0wn1/subscriptions","organizations_url":"https://api.github.com/users/theunkn0wn1/orgs","repos_url":"https://api.github.com/users/theunkn0wn1/repos","events_url":"https://api.github.com/users/theunkn0wn1/events{/privacy}","received_events_url":"https://api.github.com/users/theunkn0wn1/received_events","type":"User","site_admin":false},"created_at":"2015-08-30T03:05:15Z","updated_at":"2015-08-30T03:05:15Z","body":"IRL AC systems are not linearly better than the equivalent DC circuit, And arbitrarily defining AC to be X times better than DC would not do us any good, as people will find a way to just use the AC system if they could, because its more 'efficient' than DC. in fact, DC is more efficient with transfering power in HVDC systems than HVAC systems, for certain applications.\r\n\r\nAll that i am proposing is to use a different power drop system that interacts more like the real world, by doing so it becomes more immersive. If @BluSunrize adopts the model i described in my previous post, power loss would be a quadratic function rather than an linear function. The higher the voltage on the line, the farther the power will go; to an extent. My model (based on RL) self-clamps maximum voltages for a given line to the principle of diminishing returns, there is a point where increasing the voltage any higher just reduces maximum distance. It becomes a trade off, do i want extreme RF/T or do i want maximum transmission distance?\r\n\r\nthe way MC works and the way RF works, an AC system *in principle* would be rather dificult to program. RF is a 'push-based' power distribution system, AC is power that flows in **both directions** down the transmission lines, alternating at x reversals per second. Since RF is push-based system, both the sender and the receiver would need to be able to generate charge, consume charge, pull charge, and push charge. the RF system just is not designed for this.\r\n\r\nWe don't need 'real' AC, we just would want 'realistic' AC. Something that in principle i just don't see how it could be done with the RF api. If you come up with a way to make it work, please share the Proof of concept"}}
