Re: Catalog of the Weird Parallels
I wanted to make teleporting a man to the Moon take about as much energy as operating the LHC. I used 300 lbs for the person's weight (assuming they would need a spacesuit), 238900 mi for the distance to the Moon, and 200 MW for the energy used by the LHC. This gives a base energy requirement of 2.8 W per mi per lb.

Re: Catalog of the Weird Parallels
SG minus One
This is an informal designation for a recently discovered world that was at first assumed to be a close Parallel but definitely not an Echo with a local date in the 19902. Then while browsing through names in general databases trying to find where this world may have diverged a researcher found a Captain Samantha Carter in the USAF. Not that uncommon a name but a check determined that she was a dead ringer for the TV character complete with ridiculously high IQ and overachieving academic credentials. However, further searches turned up no Daniel Jackson or Colonel O'Neal or any other cast members and no sign of the Stargate. Then other names started coming in. There's a brilliant entomologist who's a CSI in Las Vegas, a clever fellow who looks rather like O'Neal and similar TV characters too. The general rules as they have been worked out are that the whole cast of the TV show never shows up and exact dates don't match up with any broadcast history. Indeed some don't even come in the right decade. Specific (and particularly fantastic) events that occurred in the show never happened and indeed the anomalous people do seem to be totally mundane except for innate human talents. Infinity doesn't even really know how to describe this world. "Sub-Myth" or maybe "Fragmentary Myth Parallel"? Right now it's being closely watched and there is a ban on recruiting exceptional locals. When or if the ban is lifted there's going to be a _big_ traffic jam of recruiters trying to get to Carter first.

I actually think kilo watt hours per ton is the nicest measurement, given that that's what we bill power in and ship freight with. Which drops us to the stupid low number of .000538 Kilowatt Hours per ton-mile. At 15 cents a Kilowatt hour, It costs about $2.50 to send a very overloaded Toyota Corolla to the moon. Much pricier is mars, which drives that price up to about $2500. Or I could send from London to Brisbane for the low cost of 4 cents per ton. At that point the main expense is the loading crew sticking all this junk through the portal. I'd personally NOT increase cost with distance.

I chose to use the LHC as an example because it is an energy intensive project. Looking at the Powering CERN website, CERN as a whole uses 1.3 TWh of electricity per year. That is roughly 3.56 GWh per day. Requiring 3.56 GWh of electrical energy to send one US ton of matter to the Moon as a baseline, the energy requirement is ~15 kWh per mi per US ton. To send a man to the Moon would cost about $537.5K for the electricity alone. Traveling between Columbus, Ohio and Washington DC (about 327 miles as the crow flies) would cost $4905/ton. Or about $500 per person if you go with a ten person group. I like 15 kWh/ton-mile for the energy requirement. This makes extraterrestrial travel an expensive novelty while still making it more practical than it is now. At the same time, for terrestrial use it is about as affordable as flying is today.

Re: Catalog of the Weird Parallels
We could make cost proportionate to the root (or cubed root) of distance traveled. In fact, an extreme cost like that would tend to make warp portals function more like stargates.
An alternative that makes energy costs proportionate to the square of the distance tends to produce a stepping-stone approach, also worth considering. OK, I've been messing with this for a while. 100WH*((distance in Km)^0.5) gives a nice curve. A 1 person trip one KM costs $1.20. From SF to NY it's $75. Earth to Luna is $736. Earth to mars is between $8,000 and $24,000. Earth to Saturn is in the ballpark of $40,000. Alpha Centauri, however, is an astronomical $7-8 million, and requires three Three Gorges Dams working for an hour to power it -- a Nine Gorges Dam, if you will.

Re: Catalog of the Weird Parallels
I assume these gates require all the energy up front. That means ultra expensive gigantic capacitors for interplanetary trips. I don't know where the slope change in price would be, but it wouldn't be so linear.
Shouldn't volume or at least cross sectional area matter for gates?

We can use dimensional analysis to convert your formula to work with miles by multiplying the distances by a conversion factor. In this case, the conversion factor would be (0.62 mi/1 km)^(1/2). So the formula would become ~78.75WH*distance^(1/2), with distance being in miles. Using 75 WH would be a close enough approximation for game purposes. |

Anyway, to answer your question, maybe the gate itself acts as the capacitor? More stuff I need to work out I guess. |

Re: Catalog of the Weird Parallels
I think that's how the magic Stargates worked. They could absorb nearly any energy source and expend it instantly to power transit.
It depends on how fiddly you want them to be. Fraught with limitations and resource management or background vehicle.
