The Army is currently developing tanks that run on hydrogen fuel cells
The U.S. military often struggles – unsuccessfully – to supply enough batteries for troops’ equipment. GPS units and radios demand a lot of energy, so a sustainable source would be really beneficial.
That’s why the U.S. Army has created the Rucksack Enhanced Portable Power System (REPPS), which collects solar energy for the troops in Afghanistan, where there are high levels of sunlight.
The REPPS features a 62-watt, anti-glint solar panel blanket tucked into a backpack. Not only can the system recharge batteries in a matter of hours, it can also be hooked up to electronic devices, providing them with more power.

Your apartment is heated by the warmth of human bodies in a nearby Metro station – creepy or cool?
We’re not sure, but French engineers are moving ahead with plans to install the experimental heating system in a public housing project in Paris.
The caloric heat collected from Metro passengers, as well as the heat collected from the train itself, will funnel through an underground corridor to heat exchangers that will push warm air through the building’s pipes.

If you need examples of cool things engineers can do in college, consider this: mechanical engineering students from Ohio State University work together building alternative-fuel race cars as part of the Buckeye Bullet team.
Not cool enough? Well, the team just broke the electric car land speed world record with their most recent vehicle, the Buckeye Bullet 2.5.
Racing on the Bonneville Salt Flats in Utah last week, the Bullet 2.5 reached a peak speed of 320 miles per hour and logged a two-way average speed of 307.66 miles per hour.

Switching to electric cars has a lot of advantages: it would reduce city pollution, decrease our dependence on oil, and save us money from rising gas prices.
And now there is Blink, an electric charging station that will hopefully pave the way of an electric vehicle revolution.
