Autonomous trolley system
Autonomous trolleys include an integrated power source, which energy can be utilized for integrated trolley systems such as a wheel assist module, heating module, and cooling module. The power source may include a fuel cell system or a rechargeable electrical energy storage device or a combination thereof. The rechargeable electrical energy storage device can be charged by any other power source, including a fuel cell system. The trolley can also be equipped with a fuel tank for easy and safe refueling of a fuel cell system.
1. A system comprising:
(A) at least one service trolley, the at least one service trolley comprising:
(i) a container;
(ii) a plurality of wheels attached with the container and configured to support the container relative to a support surface and to facilitate movement of the container relative to the support surface; and
(iii) at least one fuel canister housed at least partially on or at least partially inside the container; and
(B) at least one docking station position, the at least one docking station position located on a craft and configured to receive the at least one service trolley for heating or cooling of at least some contents of the at least one service trolley, the at least one docking station position comprising:
(i) at least one fuel cell system configured to receive fuel from the at least one fuel canister housed at least partially on or at least partially inside the container of the at least one service trolley when the at least one service trolley is received by the at least one docking station; and
(ii) at least one temperature regulating module arranged to remain with the at least one docking station when the at least one service trolley is moved away from a state of being received by the at least one docking station, the at least one temperature regulating module configured to receive at least one product from the at least one fuel cell system, wherein the temperature regulating module is configurable for at least one of cooling or heating contents of the at least one service trolley (a) when the at least one service trolley is received by the at least one docking station position and (b) by use of the at least one product received by the temperature regulating module from the at least one fuel cell system.
2. The system of claim 1 , wherein the at least one fuel cell system provides power to a galley of the craft.
3. The system of claim 1 , wherein the at least one fuel cell system provides power to a lower deck storage of the craft.
4. The system of claim 1 , wherein the at least one fuel canister is removable.
5. The system of claim 1 , wherein the at least one fuel canister is refillable.
6. The system of claim 1 , wherein the container comprises walls containing insulation.
7. The system of claim 1 , wherein the at least one docking station position is located in a cabin of the craft.
8. The system of claim 1 , wherein the at least one docking station position is located in a cargo bay of the craft.
9. The system of claim 1 , wherein the container further comprises a power source housed at least partially on or at least partially within the container and configured for providing power to at least one system of the at least one service trolley housed at least partially on or at least partially within the container.
10. The system of claim 9 , wherein the at least one system of the at least one service trolley comprises at least one of the group consisting of:
a drive-assist system configured to assist at least one of the plurality of wheels to turn to move the container;
a braking system configured to resist turning of at least one of the plurality of wheels to resist movement of the container;
a heating system for heating at least some contents of the at least one service trolley;
a cooling system for cooling at least some contents of the at least one service trolley;
a drink dispensing system; and
a system for processing fruit into juice.
11. The system of claim 9 , wherein the power source comprises an onboard fuel cell system.
12. The system of claim 11 , wherein the onboard fuel cell system of the power source comprises a replaceable fuel cartridge.
13. The system of claim 12 , wherein the fuel cartridge for the onboard fuel cell system of the power source is refillable.
14. The system of claim 9 , wherein the power source comprises an electrical energy storage device (EES).
15. The system of claim 14 , wherein the EES is rechargeable.
16. The system of claim 15 , wherein the EES is configurable for at least recharging from a fuel cell system.
17. The system of claim 15 , wherein the EES is configurable for at least recharging from an electrical system of the craft.
