A Danish hotel is pioneering a pedal-power electricity generation scheme it hopes will catch on（理解，变得流行） in other countries.

The Crowne Plaza Copenhagen Towers, 15 minutes from the centre of the Danish capital and five minutes from Scandinavia's main airport, is installing two exercise bicycles hooked up to（连接到） generators.

Guests will be invited to jump on and start pedaling -- and if they produce enough electricity they will be given a free meal.

From June, they will be able to race against the 366-room hotel's solar panel system in a bid to produce the most electricity.

"Anyone producing 10 watt³ hours of electricity or more for the hotel will be given a locally produced complimentary⁴（称赞的，赠送的） meal encouraging guests to not only get fit but also reduce their carbon footprint and save electricity and money," the hotel said in a statement.

Hotel spokeswoman Frederikke Tommergaard said the free meal offer applied⁵ only to paying guests, not passers-by.

The value of the meal -- any one of the main courses on the hotel restaurant or lobby（大厅，休息室） bar's menu -- is about 240 Danish crowns (28.50 pounds), she told Reuters.

The electric bikes will be up and running from April 19 and the plan is to test the idea for a year with a view to expanding it to more Crowne Plaza hotels, part of the InterContinental Hotels Group.
