Sweat for Going Green

Forget alternate fuel sources, solar panels and wind turbines, a hotel that says it is one of the “greenest” in the world has found a new source of renewable energy – sweating guests.

Those staying at the 366-room Crown Plaza Copenhagen Towers will be encouraged to head down to the gym to spend time on its new fleet of electricity-generating exercise bikes. The bikes have iPhones mounted on the handlebars which monitor how much power is being produced and fed into the mains supply of the hotel. Any guest producing 10 watt hours or more will be rewarded with a free meal.

The scheme is a pilot project that will run for a year, and if successful, could be rolled out to all 21 Crowne Plaza hotels in the UK.

“The electric bikes offer our guests the chance to get fit and help power the hotel at the same time,” said Allan Agerholm, the hotel’s general manager. “It will be interesting to see how many guests take part and how much electricity we generate.”

Getting the free meal is surprisingly easy. The hotel’s calculations suggest one guest cycling at 30kmph for an hour will produce around 100 watt hours of electricity, meaning that reaching the threshold for the meal should take only six minutes.

Critics might argue that even those who cycle for a full hour will be making a rather token contribution to the energy use of a huge city hotel – 100 watt hours of energy is only enough to light a single 100 watt bulb for one hour. However the hotel counters that it wanted the target to be “achievable” so as many people as possible take part.

The hotel, which opened in November last year, is attempting to become carbon neutral. It has EU Green Building and Green Key certification and uses a groundwater-based cooling and heating system, low energy lighting and hand dryers, and is covered in solar panels on its south-facing aspects. So will its latest scheme catch on at other hotels around the world?

It sounds crazy but I love this idea!! And a great way to burn calories before partaking in some delicious dinner!
