Has it been a while since you've had anything to drink? A few hours, a day, two days? I"m starting to feel anxious just thinking about it.
The method on display here is not a manufacturing process, but a thinking process. The WaterBrick was developed by Wendell Adams at WaterBrick International and folks at FPM Tooling & Automation in response to a challenge to provide that most vital of substances, water, to those in emergency need of its life-giving qualities. Devising a method for successfully air-dropping water to remote locations is a significant engineering challenge in itself. The exeptional thing about the WaterBrick project is that the the goals were expanded to include both container reuse and ongoing economic viability.
After palletized WaterBricks survive the air-drop and the contents are, gratefully I expect, consumed, the bricks can be filled with sand or earth and stacked to create long-term shelter. If the first courses are buried, they can act as their own foundation. You can see a prototype building on the WaterBrick International website. The thinking proceeded beyond the creation of individual structures to include the possible creation of a village compound. All things considered, this is a noble use of the blow-molded container. I wish WaterBrick and those they serve, the best success.
I think I'll (gratefully) go get a drink of water.
