Gadgets that Will Self-Destruct on Demand

john rogers

With a little help from Pentagon funds, Darpa, the Defense Advanced Research Agency, has been developing devices that will be able to self-destruct on command. In order to render themselves inactive, and effectively transform into thin strands of mush, devices begin to biodegrade when exposed to water. And thus, biological fluids and other liquids. Such transient electronics would prove useful in multiple applications, including use for medicinal and military purposes. In healthcare facilities, devices could be placed within post-operative wounds to monitor for signs of infections, dissolving into the patient’s bodily fluids over time. During military missions, the technology could… read more

The Bionic Knee – Powering More Than You Think

Bionic Power, a technology company in British Columbia, has developed a knee brace that allows you to possess energy-generating powers. It comes in the form of a biochemical energy harvester, called the PowerWalk. Whilst walking, whenever you brake, and your knees buckle, you have the potential for generative braking. The PowerWalk knee brace has the ability to capture this motion, allowing you harvest the energy generated from the bending and locking of your knees whenever you wear it. Each PowerWalk knee brace weighs 1.7 pounds, and  generates around 12 watts of energy at the average walking speed. Kept steadily, you… read more

Portable Fuel Cells

Portable fuel cells

Fuel cells may outdo themselves – with the advent of mobile clean energy, or portable fuel cells, which are expected to have a greater and more rapid-growing market than fuel cells used for transportation. Portable fuel cells are either built into mobile devices or used to charge them, ridding the need for wall sockets. They operate at a low cost and can be used in off grid operations. Benefits of portable fuel cells include a longer run time than batteries, rapid recharging, and a significant weight reduction compared to conventional batteries. Portable fuel cells may also prove crucial in the midst of natural… read more

Government Indifference

Government institutions are meant to be at the forefront in the fight to protect the environment from attack. This means that government is expected to at least refrain from activity which would be seen and proven to have adverse effects on environmental media. When government fails to do so, this constitutes a grave injustice. A prime example is a situation that has ensued in the United States. A host of environmental groups in the United States have filed a lawsuit against the government asserting that it has failed to regulate military drills involving the sinking of old ships in the… read more
