Eco Factor: Portable solar generator provides 300W of continuous power.
The Office of Naval Research has developed the GREENS or the Ground Renewable Expeditionary ENergy System, which allows the marines to generate 300W of continuous power using sunshine. The suitcase-based system carries a stackable 1600W solar array combined with rechargeable batteries to yield up to 300W of power.
The portable and elegant system also doubles as a durable transportation platform and will be used by the marines to support field operations in Iraq. By reducing the logistical supply chain for fuel, GREENS, and other projects like it, will help cut fuel use, cost and the associated threats to vehicle resupply convoys in Afghanistan and Iraq.
