A high-speed transportation system includes at least one transportation structure having at least one track, at least one capsule configured for travel through the at least one structure between a plurality of stations, a propulsion system adapted to propel the at least one capsule through the structure, and a levitation system adapted to levitate the capsule within the structure. At least one track is positioned to provide balancing force vectors to achieve stability for the capsule.

A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

An energy storage system includes a crane and a plurality of blocks, where the crane is operable to move blocks from a lower elevation to a higher elevation (via stacking of the blocks) to store electrical energy as potential energy of the blocks, and then operable to move blocks from a higher elevation to a lower elevation (via unstacking of the blocks) to generate electricity based on the kinetic energy of the block when lowered (e.g., by gravity). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the power grid.

Generally, a transportable lift system operable to capture and raise materials from a first height to a second height. Specifically, a lift having first and second length adjustable supports having second ends pivotally coupled to allow opposite first ends to be secured to a surface a distance apart to allow a line pay-out device coupled to the first length adjustable support to pay out a line proximate the first length adjustable support second end, whereby materials attached to the line can be raised from a first height to a second height.

A lifting device for lifting a payload within an elevator shaft in a controllable manner has a platform to be fixed in the elevator shaft, a holding device to be fixed to the payload, a lifting cable attached to the holding device, a securing cable secured to the holding device (such as, for example, a pulling device secured to the platform), and a catching device secured to the platform. The pulling device actively and controllably displaces the lifting cable relative to the platform. The lifting device displaces the securing cable in the event of a relative movement between the holding device and the platform such that the securing cable remains tensioned. The securing cable and the catching device are configured such that the catching device blocks a further relative movement between the securing cable and the catching device in the event that the lifting cable fails.
