Abstract

A vessel including a concentrator configured to concentrate electromagnetic (EM) radiation received from an EM radiation source and a complex configured to absorb EM radiation to generate heat. The vessel is configured to receive a cool fluid from the cool fluid source, concentrate the EM radiation using the concentrator, apply the EM radiation to the complex, and transform, using the heat generated by the complex, the cool fluid to the heated fluid. The complex is at least one of consisting of copper nanoparticles, copper oxide nanoparticles, nanoshells, nanorods, carbon moieties, encapsulated nanoshells, encapsulated nanoparticles, and branched nanostructures. Further, the EM radiation is at least one of EM radiation in an ultraviolet region of an electromagnetic spectrum, in a visible region of the electromagnetic spectrum, and in an infrared region of the electromagnetic spectrum.

First claim

What is claimed is:

1. A vessel, comprising:
a concentrator configured to concentrate electromagnetic (EM) radiation received from an EM radiation source; and
a complex configured to absorb EM radiation to generate heat,
wherein the vessel is configured to:
receive a cool fluid from the cool fluid source,
concentrate the EM radiation using the concentrator,
apply the EM radiation to the complex, and
transform, using the heat generated by the complex, the cool fluid to a heated fluid,

wherein the complex comprises:
a carbon moiety, and
an encapsulating dielectric layer configured to maintain a plasmon resonance of the complex.

2. The vessel of claim 1 , further comprising:
a valve configured to control flow of the heated fluid from the vessel; and
a first temperature gauge configured to measure a temperature inside the vessel, wherein the valve opens to release the heated fluid from the vessel when the temperature read by the first temperature gauge is above a temperature threshold,
wherein the valve and the temperature gauge are controlled by a control system, wherein the control system comprises a photocell and a second temperature gauge, which, when used with the first temperature gauge determines a speed at which a pump operates to achieve a target temperature of the heated fluid.

3. The vessel of claim 1 , wherein the concentrator is a lens.

4. The vessel of claim 1 , wherein the concentrator is a parabolic trough and wherein the vessel is a section of pipe coated with the complex.

5. The vessel of claim 1 , wherein the complex is coated on an interior of the vessel.

6. The vessel of claim 1 , wherein the complex is suspended in the fluid in the vessel.

7. The vessel of claim 1 , wherein the vessel is portable.

8. The vessel of claim 1 , wherein the complex further comprises a second carbon moiety that is aggregated to the carbon moiety to form an aggregate.

9. The vessel of claim 8 , wherein the aggregate has a broader absorption spectrum relative to an absorption spectrum of the carbon moiety or an absorption spectrum of the second carbon moiety.

10. The vessel of claim 9 , wherein the absorption spectrum of the carbon moiety is different than an absorption spectrum of the second carbon moiety.

11. The vessel of claim 8 , wherein the carbon moiety has a first structure, wherein the second carbon moiety has a second structure, wherein the first structure and the second structure are different structures.

12. The vessel of claim 1 , wherein a thermal efficiency of steam formation by the complex is at least 80%.

13. The vessel if claim 1 , wherein the complex is supported on a polymer film, thereby fixing the complex to a surface.
