Then, when the rubber was sufficiently wound, a brake could be applied and the keels feathered to minimise drag. When thrust was required, the keels could be set to a steep angle relative to the direction of travel and the brake disengaged. The rubber would then spin the keel rotor, which would push against the Ether, propelling the ship.
Reducing the crosslink density of rubber improves rubber bitumen storage stability. Solubilization blending can be considered a sustainable and capable approach.

By exerting a force on the object through some distance you have changed the energy state of the object. We say that the stretched rubber band or compressed spring stores elastic energy—the energy account used to describe how an object stores energy when it undergoes a reversible deformation. This energy can be transferred to another object ...

2.1. Energy-Storage Cycle. Much like other energy storage media, a water balloon operates in a cycle to store and supply energy. Figure 1 illustrates the processes of the cycle, in which a balloon is inflated with cold water, heated, deflated when it is warm, and cooled when it is flat. The inflation process deposits energy into the balloon, …

The energy the rubber band has stored is related to the distance the rubber band will fly after being released. So can you guess one way to test how much energy a stretched rubber band contains?
This leads to elastic energy storage and thus change in the internal energy. To better characterize this effect and to highlight kinetics effects in the internal energy change, energy balances were carried out at any time during the deformation cycles, by comparing the strain power density P s t r a i n and the heat power density s .

A lined rock cavern (LRC) is an alternative container for compressed air energy storage (CAES) to store high-pressure air that is later used to produce electricity. A critical requirement of CAES in LRCs is that the inner seal should provide adequate sealing capacity to prevent air leakage from LRCs.
The use of hybrid power systems [40] in rubber-tired gantries (RTG) compared to diesel ones can reduce CO 2 emissions by 60-80%, and maintenance costs by about 30% [40].
Final report. Title: Rock cavern linings for compressed-air energy storage. Final report. Technical Report · Thu May 01 00:00:00 EDT 1986. OSTI ID: 5858885. Calculations suggest that an average air leakage of 1% per day from a 220-MW underground compressed-air storage plant represents a cumulative energy loss of up to $100,000 per year.

When thrust is needed, the keels would be set to a steep angle and the brake disengaged. The feathering of the keel-propeller (and therefore the thrust) could be controlled by a governor/throttle setup.
