Lets say you’re rich. Really rich. Richer than all hell. And you want to “go green.” Before you answer with “cut back on my private jetting” or “unload a house or two,” pause for a moment and recall just how filthy wealthy you are.

Yup. Solar sails for your super yacht.

An Australian-based tech firm, Solar Sailor, is working on just that—massive sails embedded with solar panels. A computer pivots the sails toward the sun (it’s always sunny in the French Riviera!) and the energy collected is used to power the yacht. CEO Robert Dane thinks a whopping 10 percent of the fuel consumption could be offset by the panels. Ten percent? Wonder how much energy you’d save by turning down the jets on your diamond-encrusted hot tub.
