Using High Efficiency Batteries for Jump Drives

Could H2 be referred to as "Jump Fuel" not because it adheres to the definition of "Fuel" when used for jump but because it is also used as fuel for the power plant and is stored with it in the same "fuel tank"? So while it is indeed fuel (for the power plant) it is not in fact "fuel" for jump while still being used "in some way" for jump?

Wouldn't it be silly to have a "fuel tank" full of H2 for the power plant and a "jump liquid" tank also filled with identical H2? So people adopt the (incorrect) practice of calling it "Jump Fuel" even though it isn't literally "Jump Fuel"?

Could, sure, but it would not be my first assumption.

I would await more information.

I've been cutting corners for quite a while.

Fuel's a gimmick in Traveller, to ensure certain game outcomes.

Remember, not a physicist or engineer.

But I suspect that if the jump drive actually burned all that hydrogen, the starship would blow up.
 
Both are going to be outperformed by lesser jump ships UNLESS the route requires J-5. If all ships are going starport to starport and the conventional ships refuel in hours, not a week, the J-5 ship can be there and back before the Collector ship can even start their next jump.

Obviously, but maybe not. Remember, most ships only jump twice a month. Both ships can jump twice a month.

200-ton ship Average Cargo per month (tons)
J-1/Collector 30-ton/7-ton 160 / 206
J-2/Collector 55-ton/9-ton 110 / 202
J-3/Collector 80-ton/11-ton 60 / 198
J-4/Collector 105-ton/13-ton 10 / 194
J-5/Collector 130-ton/15-ton -30 / 190
J-6/Collector 155-ton/17-ton -80 / 186

I decided to do a direct comparison with an existing design of mine that only goes up to J4, but I extended the collectors up to J6.

My 100,000-Ton Atlas Merchant Tenders are TL15, maneuver 1, and carry 5,000-Ton Type V pods of cargo, fuel, passengers, or low passengers. Here is the comparison.

J1 Normal: 118 pods (590,000 tons total, 5.9x the ship's tonnage)
J1 Collector: 302 pods (1,510,000 tons total, 15.1x the ship's tonnage)
J2 Normal: 55 pods (275,000 tons total, 2.75x the ship's tonnage)
J2 Collector: 178 pods (890,000 tons total, 8.9x the ship's tonnage)
J3 Normal: 31 pods (155,000 tons total, 1.55x the ship's tonnage)
J3 Collector: 123 pods (615,000 tons total, 6.15x the ship's tonnage)
J4 Normal: 17 pods (85,000 tons total, 0.85x the ship's tonnage)
J4 Collector: 92 pods (460,000 tons total, 4.6x the ship's tonnage)
J5 collector: 72 pods (360,000 tons total, 3.6x the ship's tonnage)
J6 Collector: 58 pods (290,000 tons total, 2.9x the ship's tonnage)

For comparative purposes, my J1 1,000,000-Ton Hercules-Class Merchant Tender can haul 128 50,000-Ton pods (6,400,000 tons total, 6.4x the ship's tonnage). In MTU, it's the monster of the jump lanes.

Unless I am misreading your post, it looks like Collectors are better every single time. Makes Me wonder why normal jump drives even exist for commercial ships.

They are and I would guess it’s not common because the Imperium doesn’t have the tech. I know it’s in High Guard, but only the Darrians have a few and they might not have shared the tech or even word that it existed.

Considering that shipbuilding tech passes between them, one builds the other´s ships, who knows?
 
As I recall, the Darrians had to order technological level fifteen starwarships from Imperium shipyards.

I guess someone, who's interested enough, should comb through the Darrian data, and figure out exactly what shape their current industrial base, is.

Someone should, but I doubt that I have all of the right books.
 
One important consideration is that the collector needs to be in space throughout the week. And as written in High Guard does not supply any of a ship's power needs (this differs from CT Annic Nova, but Mongoose seems to have decided you need to stick a fusion plant into every legacy battery or solar powered ship...). And CANNOT jump out early. They would be highly vulnerable to hostiles compared to regular ships.
 
Someone proposed a breakaway hull, where the Collector installed one wanders around, collecting butterflies, while the primary hull, does it's business downstream, or locks together with an already stuffed breakaway hull, to boldly go, to infinity and beyond.

Without shore leave.

Yep. That would work for established lines or common hull types. They have to be the right size to work with the hull tonnage and the jump number.
