Why It’s Green: Tells time by using salted water; the device’s electrodes harvest energy from the liquid to fuel the nightstand-friendly gizmo’s simple digital LCD.
Why Buy: No batteries necessary, it’s small enough to stuff into any carry, and it’s especially easy and cost-effective to keep going the next time you’re cruising the coast of Sicily.
Practical Applications: Ensuring you’re prompt for massage appointments, walking tours, and naturally, dinnertime at Chateau Elan.
