Problem Statement
- Existing atmospheric water harvesting technologies are often bulky, electricity-dependent, and unaffordable for rural and lower-class communities.
- Prior inventions lack compactness, simplicity, and affordability, hindering adoption by marginalized populations.
- The need for continuous electricity supply restricts accessibility to water in regions with unreliable power infrastructure.
- Therefore, there is a gap in the market for a portable, mechanically-operated, affordable, and easily deployable atmospheric water harvesting solution suitable for rural and lower-class demographics.
Technology
- The invention aims to utilize an electromechanical system to efficiently condense atmospheric water by converting gravitational potential energy.
- It involves three main subsystems: a condenser, a generator, and a lifter, with a focus on utilizing thermoelectric cooling and mechanical power generation.
- Gravity is harnessed as a consistent power source, with a 40 kg dead mass dropping through a height of 3 meters over 5 minutes to generate electricity via an intermediary gear train.
Key Features / Value Proposition
Innovative Waater Harvesting Solution:
- Offers an innovative electromechanical system harnessing gravitational potential to efficiently condense atmospheric water, addressing the pressing need for sustainable water sources.
Affordable and Accessible:
- Achieves functional hepatocyte differentiation in just 14 days, providing a time-efficient alternative to the conventional 28-day duration associated with growth factor-based methods.
Reliable and Sustainable:
- Ensures reliability and sustainability by leveraging gravitational power for consistent operation, making it suitable for regions with limited infrastructure and addressing the global water crisis.
