Durable tandem
Pinion Gear box. Not light but an interesting technology. 18 gears with 11-12% cahnge between each.
From FAQ page:
Is it possible to use the P1.18 gearbox transmission in a tandem?
A tandem-specific version of the P1.18 gearbox is currently being tested.

It appears they took some old Shimano shifters and wrapped them fiber then painted. I guess they could do anything with a bike that will never be ridden.
