Het Amerikaanse leger zet zwaar in op zonne-energie als militaire brandstof van de toekomst

US marines go to war with solar cells embedded in their rucksacks efficient enough to recharge lithium-ion batteries for radios and greatly lighten loads.

Field patrols will soon have almost weightless solar blankets as well. These will be able to capture a once unthinkable 35pc of the sun's light as energy with thin membranes, a spin-off from technology used in satellites.
