The Delta

The Delta is a Spaceship-Space Hotel hybrid that takes people to and from the Tau Alpha Complex. It is a 1 Mile (1.6km) hunk of Super Obsidian, with a fusion engine. Super Obsidian is a new material, made with Obsidian, Carbon Nanotubes, Graphene, and Steel. It made exclusively by the Alpha Commission, and it sells for high prices, as it is difficult to make.

Construction started in early 2021, and construction was finished in late 2021. It is well maintained, and has not had any close calls with destruction.

Capacity, Travel Times, and Economics
The Delta can hold up to 1 Million people at a time, and there are over 150 Million people in the Tau Alpha Complex. That means the Delta made at least 100 round trips to the complex and back, to factor in the birth rate of the complex.

Travel Times to the complex and back is in total 10 days. The Delta is powered by a fusion engine, which emits hot, blue flames.

The cost to build the Delta was $1 Trillion ($1,000,000,000,000), and it is $50,000 for a trip to the Tau Alpha Complex per person. Adding up the cost for the complex, it is nearly $7 Trillion in total. However, this was fully paid off by the 150+ Million people that traveled.
