at least one sensor electrically connected with the controller;
a data storage device electrically connected with the controller; and
a data communications device electrically connected with the controller,
wherein the rechargeable battery, the Stirling engine, the compressor, and the ballast tank are contained within an elongated vessel housing, and
wherein the rechargeable battery, the Stirling engine, the compressor, and the ballast tank are serially arranged between opposed first and second ends of the elongated vessel housing, and
wherein the ballast tank is arranged closer to the first end than to the second end.
2. The vessel as recited in claim 1 , further comprising a fuel tank and a fuel pump in fluid communication with the fuel tank and the combustor.
3. The vessel as recited in claim 1 , further comprising a tether operable to moor the vessel.
4. The vessel as recited in claim 1 , wherein the controller is configured to collect data via the at least one sensor and store the data in the data storage device.
5. The vessel as recited in claim 1 , wherein the controller is configured to transmit data from the data storage device via the communications device.
6. The vessel as recited in claim 1 , wherein the controller is configured to manage buoyancy via either charging the ballast tank with water to reduce buoyancy or charging the ballast tank with air via the compressor to increase buoyancy.
7. The vessel as recited in claim 1 , wherein the controller is configured to charge the rechargeable battery by activating the compressor to provide air to the combustor to generate heat in the Stirling engine such that the Stirling engine drives the electric generator and provides electric current to the rechargeable battery.
8. A selectively submersible vessel comprising:
a combustor,
a Stirling engine,
an electric generator,
a rechargeable battery,
a compressor,
a ballast tank,
a snorkel,
at least one sensor,
a data storage device,
a data communications device, and
a controller,
wherein the rechargeable battery, the Stirling engine, the compressor, and the ballast tank are contained within an elongated vessel housing, and
wherein the rechargeable battery, the Stirling engine, the compressor, and the ballast tank are serially arranged between opposed first and second ends of the elongated vessel housing, and
wherein the ballast tank is arranged closer to the first end than to the second end,
wherein the controller is configured with one or more of a plurality of control modes including Mode 1, Mode 2, Mode 3, and Mode 4,
wherein: in Mode 1, the controller is configured to collect data via the at least one sensor and store the data in the data storage device, in Mode 2, the controller is configured to transmit the data from the data storage device via the communications device, in Mode 3, the controller is configured to manage buoyancy via either charging the ballast tank with water to reduce buoyancy or charging the ballast tank with air via the compressor to increase buoyancy, and in Mode 4, the controller is configured to charge the rechargeable battery by activating the compressor to pump air to the combustor to generate heat in the Stirling engine such that the Stirling engine drives the electric generator and provides electric current to the rechargeable battery.
9. The vessel as recited in claim 8 , wherein, in the Mode 4, the compressor draws the air from the snorkel.
10. The vessel as recited in claim 8 , wherein, in the Mode 4, the compressor draws the air from the ballast tank.
11. The vessel as recited in claim 8 , further comprising a fuel tank and a fuel pump in fluid communication with the fuel tank and the combustor.
12. The vessel as recited in claim 8 , further comprising a tether operable to moor the vessel.
