Many energy sources in nature and industrial settings produce only small temperature differences, known as low-grade thermal energy. Traditional systems, like Stirling engines, struggle to efficiently convert this energy into usable kinetic or electrical power. As a result, much of this energy goes to waste, limiting its practical use in renewable energy applications.
Core Features
This invention provides a thermal energy extraction system that efficiently converts small temperature differences into motion and electricity. It consists of:
- A closed-loop conduit containing a fluid that expands and contracts based on heat.
- Two heat exchange sections—one hot and one cold—that cause temperature-driven fluid movement.
- A reciprocating motion system (like a piston or an expander) that moves as the fluid cycles between expansion and contraction.
- Fluid flow diverters that switch between heat sources to optimize energy use.
- A generator or flywheel that converts motion into electrical power.
What Makes It Unique?
Unlike conventional systems that struggle with efficiency, this invention optimizes the use of small temperature differences by automatically adjusting fluid flow and heat exchange. The system cycles between hot and cold sections, ensuring continuous movement without requiring high-energy input. Additionally, it can be integrated with solar power or other renewable sources to enhance energy production.
Tangible Benefits
- Extracts energy from waste heat or environmental temperature differences.
- Reduces reliance on fossil fuels by making low-grade thermal energy more useful.
- Works autonomously with minimal maintenance, making it ideal for homes, industries, and renewable power systems.
- Increases efficiency by using regenerators that store excess heat, reducing energy loss.
Broader Impact
This invention could transform how we harness renewable energy, making previously unusable temperature differences a viable energy source. It has applications in solar energy, industrial heat recovery, and off-grid power generation, contributing to sustainability and reducing global carbon emissions.
