Amazingly Simple Water Drum Invention
The Q-Drum, a low cost rollable water container for developing countries.
The burden of fetching water, invariably over long distances by cumbersome and far too often, unhygienic means, is all too evident in rural Africa.
The idea of the Q-Drum originated in response to the needs of rural people for clean and potable water, as well as easing the burden of conveying it.
The solution had to be simple, water in adequate quantities is by far too heavy to carry, by rolling the water in a cylindrical container and not carrying it seemed to be the only solution. The container had to be durable, and breakable handles & other attachments would simply not do - in many parts of Africa even a hammer & a nail are scarce commodities.
The Q-Drum addresses these needs by providing a simplistic, cost effective and durable solution: The uniqueness of the Q-Drum lies in the idea and design of the longitudinal shaft or doughnut hole, and is acknowledged by the fact that Worldwide patents have been granted for the concept, thus confirming the novelty & inventiveness of the design.

Virtual Water: 1 Hamburger = 2,400 Liters of Water
Professor John Anthony Allan of the University of London in Britain won the award for introducing the concept of "virtual water," a calculation method that has changed the nature of trade policy and research.
"People do not only consume water when the drink it or take a shower," the institute said.
"Behind that morning cup of coffee, there are 140 liters of water that was consumed to grow, produce, package and ship the beans."
That is about as much water as a person in England uses on average for all daily drinking and household needs.
"For a single hamburger, an estimated 2,400 liters of water are needed. In the USA, the average person consumes nearly 7,000 liters of virtual water every day." It said that was more than three times the average consumption of a Chinese person.
In a report last year, it projected that 250 million people in Africa could suffer more water shortages by 2020, while a quickening thaw of Himalayan glaciers could disrupt flows on which millions of people in Asia depend.

Innovative Flood Bag
Benefits:
1) Save money, time, and labour in the war against flooding with reusable bags filled with a safe biodegradable polymer and water
2) Build dikes in half the time with fewer people
3) Deploys quickly and easily
4) Easy to use: automatically inflates in only 3 - 5 minutes (expands from 1 lb to 34lbs)
5) Requires less labor to prepare or use
6) Can be inflated at point of use, no need for heavy infrastructure
Preparation (remotes filling with sand and transported to site)
7) Very efficient: requires no more storage space than a normal, empty
sandbag
8) Easy to ship or move
9) Reusable
10) Environmentally friendly
11) Uses natural jute bag or polypropylene plastic bag and water absorbing
resin (PRTR approved, the same as baby diapers)
12) Product dissolves naturally in ground
Pretty cool invention... although I wonder if it's not just a big baby diaper. I've recently used diapers to suck water out of a carpet, worked pretty well. More.
