Ventures into science seem to turn fiction books into reality more often than not. An example of this comes from a group of researchers at Purdue University who seem to have found a manner of using an aluminium alloy to cause an extremely safe and stable chemical reaction to perform good in the world. With Aluminum being the third most abundant and Water being the most abundant resource on Earth, a machine of this nature would be the epitome of sustainability! Sadly we won’t be seeing this technology out in the open any time soon as there doesn’t seem to have been a prototype machine built, that’s where you come in! Look over these a little bit and see if you can’t replicate this amazing experiment for yourself and take the world by storm! A more sustainable world begins with you!

The alloy contains aluminum, gallium, indium and tin. Immersing the alloy in freshwater or saltwater causes a spontaneous reaction, turning the water into steam and generating hydrogen and aluminum tri-hydroxide until the aluminum is used up. The hydrogen could then be fed to a fuel cell to generate electricity, producing potable water.

“The steam would kill any bacteria contained in the water, and then it would condense to purified water,” Woodall said. “So, you are converting undrinkable water to drinking water.”
The potable water could be produced for about $1 per gallon, and electricity could be generated for about 35 cents per kilowatt hour of energy.
“There is no other technology to compare it against, economically, but it’s obvious that 34 cents per kilowatt hour is cheap compared to building a power plant and installing power lines, especially in remote areas,” Woodall said.
The unit, including the alloy, the reactor and fuel cell might weigh less than 100 pounds.
