Here’s one for the I’ve-seen-it-all-now department: a dinghy seat that opens up to reveal an array of solar panels and wind generators to charge the battery for the tender’s electric motor. Pull the dink up on the beach, and it’ll recharge its own battery while you’re having a rum at the tiki bar. The brainchild of French company GEPS Techno, the “Hybrid Bench” is not yet in production, but full marks for ingenuity. How about extending the concept to a liferaft?
