Research & Development

MEDA Hawaii is developing applied research into one of the state’s most pressing resource challenges: industrial water loss.

The Problem

Cooling towers — used throughout Hawaii for hospitals, resorts, universities, and commercial buildings — lose enormous volumes of fresh water to evaporation every year. A single mid-size cooling tower plant can evaporate tens of millions of gallons annually, drawing on aquifers that take decades to naturally replenish.

70%
of major global aquifers in long-term decline
~50M gal
estimated annual water loss from a single large cooling tower plant
1 day–200 yrs
range in time for rainfall to refill an aquifer

Our Direction

MEDA Hawaii is exploring ways to reclaim water that is currently lost to evaporation in industrial cooling systems — with the goal of doing so without adding meaningful energy cost, a problem that has not yet been solved commercially. Our approach draws inspiration from Native Hawaiian flora and traditional ecological knowledge, reflecting our commitment as a Kanaka Maoli-owned firm to solutions rooted in place.

This work is in an early research and development stage. Because it involves proprietary design work, we’re keeping technical details private while we pursue funding and intellectual property protection.

Status: Early-stage R&D. MEDA Hawaii is pursuing federal research funding to advance this work toward a working prototype.
