Former NASA engineer Janne Käpylehto has innovated a floating sauna.

The 'serial entrepreneur, author and energy expert' will be attempting to sail across the Gulf of Finland to Estonia.

While the sauna is propelled by motor-power from solar panels, it's heated by a traditional sauna stove.



Saunas are not only good for your health — as it turns out, they're also good for getting around. If Burger King saunas, guerilla saunas and nude sauna emojis just didn't cut it for you, the Nordics have a new development on the sauna scene: the solar-powered sauna boat.

Former NASA engineer Janne Käpylehto, who describes himself as 'a serial entrepreneur, author and energy expert', has innovated a floating sauna on which he'll be attempting to sail across the Gulf of Finland to Estonia. The 80km journey from Helsinki to Tallinn is expected to take nine hours one way, according to an Estonian World report.

While the sauna is propelled by motor-power from solar panels, it's heated by a traditional sauna stove.

To ensure the success of the voyage, Käpylehto will bring a navigator along, and has also equipped the vessel with a lifeboat. The inventor has previously made headlines with solar-powered ice carousels.
