This is not a big surprise, but it’s exciting to contemplate: A future filled with eco hotels. Here’s an article about the greening of the hotel business. An excerpt:

At the boutique hotel Greenhouse 26, set to open next year in the Chelsea neighborhood of Manhattan, the elevator will capture energy generated when it stops, in much the same way a hybrid car recycles energy released when the brakes engage. In addition, heating and cooling will be conducted via an energy-saving geothermal system, and water from sinks and showers will be recycled for use in toilets.
Larger hotel chains are jumping on the bandwagon too. And trade associations in the travel industry are seeing “green” as a potentially profitable trend brought on, in part, by consumer demand.
