'cause the power you're supplying, it's electrifying!***

How popular do you think that going to the fitness club is? Try to guess before you scroll further!
- Have you ever gone to a fitness club?
- How many friends and relatives do you have that practice it?
- Is it regularly or only occasionally?

In 2007, 22% of the Germans stated they do fitness or jogging activities often or very often. Another 29% said they do it from time to time. It means that almost half of the population between 14 and 64 years is familiar with the idea of going to the fitness club and that a big part of it also practices it.

This is the point where we should understand that fitness clubs play an important role in the lifestyle of today's people. So it's very probable that they also start using innovative ideas and technology to reach sustainability and ecologically friendly service. This is the logic, how does the reality look like?

Well, there are clubs like Eco Fitness in Berlin and Cologne, Germany, that focus on sustainability in their processes. It means that they try to be CO2 neutral, to use energy-saving electric devices, to cooperate with partners on green projects etc. This is really cool and it should be a task for every fitness club, especially for big chains here, like McFit or Jonny M..

But there is also an idea combining the core of fitness = *movement*, with being *green*. You've probably already guessed what it is, if you've read my previous post about sustainable dance clubs and converting energy of movement into electricity.

Does it work for fitness clubs? - Yes, the muscle power used to do all the exercises on different devices, can be converted into electricity with a generator or a dynamo. There are clubs that are already applying it, for example greengymberlin. Why should we lose all that energy if we could use it to power the electricity in the gym?

Here is a cool video from the Deutsche Welle (in English), explaining how it works



Of course, the energy produced is not so huge - in order to supply only one micro-wave oven, you need 8 people cycling at the same time. But as little as it is, it doesn't mean it's useless! What's more, it can enhance people's awareness about the amount of electricity they use every day. So I'm curious what would be the next exciting idea!

Jump, jump, jump

Imagine yourself going to a dance club on Friday night. Having a drink, talking to your friends or meeting new people. Imagine dancing on the floor, lights playing with your senses. Now imagine the floor and lights connected in a circle, and the power for these lights provided by YOU. It's your movements that produce the electricity!

The creators of the Sustainable Dance Club in the Netherlands had this vision and made it happen: in Rotterdam. WATT, the first SDC was opened in 2008 - so if you're visiting Rotterdam, don't forget to check it out!












The idea of the Sustainable Energy Floor is to use human power to produce electricity where lots of people are gathering. It's composed by a number of modules, as big as 75x75x20 cm, that contain an internal generator. The size and the shape of the design can be customized, according to the preferences of the customers.

It has already been visiting places all over the world, for example San Francisco, Hamburg, Miami, Jakarta, Vancouver, Toulouse, Australia, Rio de Janeiro... Here's a video showing how the Dance Floor and other concepts like that were applied at a Rock Festival in Rio.



If you're wondering if there's a SDC near your place, maybe you can find some more information here.

I am pretty amazed how creative people can be. It's only another example that the solutions to our energy issues are sometimes right under our nose - or our feet ;) Next time I will be writing about sustainable fitness clubs and the concepts that are used there...
