RV enthusiasts who lament they can't bring their boat along on trips can rejoice in a new motorhome that serves as both a recreational vehicle and a boat. The eco-friendly Harmony by industrial designer Weili Feng is a concept RV powered by a hydrogen battery with four in-wheel motors plus a solar paddle that can be used as a sail and solar energy harvesting system. On water, a jet drive moves the vehicle along. And don't think this compact RV lacks amenities: it's said to sleep four with leisure areas, a toilet, kitchen and entertainment system.
So where can you buy one? Nowhere! Not yet, anyway.
