After environmental groups pointed out that the world's largest cruise ship - Emoji of the Seas - will create increased methane emissions due to its use of LPG gas power, the owners have introduced a new way to power the ship:

Passenger Power by Peloton!

One deck of the ship will be dedicated to housing over a thousand Peloton exercise cycles.

Each passenger will be required to cycle for a minimum of 1 hour per day during their cruise in order to generate enough electricity to power the ship, when combined with solar panels plastered everywhere and a massive wind turbine installed above the bridge.

Those passengers unable or unwilling to pedal will be charged an extra carbon-offset fee when booking their trip.

A spokesperson told FNN:

Not only will this effort by our passengers help to power the ship, it will also make them slimmer and fitter. Bonus!
