U.S. Marines Go GREENS with Portable Solar-in-a-Suitcase

The U.S. Marines are using a new 300-watt portable photovoltaic system called GREENS to power operations in the field.

While some in the civilian world are still pitching the “drill baby drill” approach to future energy, the U.S. Marines are betting on portable, sustainable energy-harvesting systems like a new 300-watt photovoltaic and battery arrangement called the Ground Renewable Expeditionary ENergy System, or GREENS.

For ease of set-up the GREENS solar panels fold out of frames that resemble metal suitcases, which also double as a durable transportation platform.  The system was developed by the Office of Naval Research in just over a year, in response to a request by Marines looking for a renewable power system to support field operations in Iraq.  It’s also one sustainable solution to the ever growing need for energy to power military field computers and other portable electronic gear.

The GREENS Solar System in a Suitcase

The suitcase-based design is an elegant solution to the need for a speedy set-up and dismantling in the field, but what is truly revolutionary about the system is the U.S. military’s clear identification of renewable, on-site harvested energy as the fuel of the future for field operations.  The system consists of stackable 1600-watt solar arrays combined with rechargeable batteries, to yield 300 watts of continuous power.  In a demonstration video of the GREENS system, the narrator states that “the 300-watt renewable system will provide a valid alternative to small generator use in the field and GREENS will cut down the tremendous logistic train it takes to deliver power right now.”

About That Logistic Train: Solar vs. Fossil

The Pentagon recently placed a price tag of $400 per gallon to deliver gas to remote outposts in Afghanistan, and that’s not counting the human cost of manning and defending convoys to deliver the fuel.  The irony is that high-tech electronic equipment is defining the war of the future, but for the most part it is still being powered by fossil fuel technology that dates back 100 years and more.  It’s no accident that the U.S. military and military veterans are pushing hard for the sustainable energy of the future, and it seems like some of us civvies have a lot of catching up to do.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
