A husband and wife team from Aberdeen plan to travel in an electric vehicle from the Arctic to the Antarctic.
This week, Chris and Julie Ramsey will embark on a 17,000-mile (27,000-kilometer) journey from the Magnetic North to South Pole.
They plan to use solar and wind energy to power their car for the majority of the journey.
During the course of ten arduous months, the pair will cross into Canada, then travel south through the United States and into South America.
Mexico, Nicaragua, Honduras, Costa Rica, Panama, Colombia, Ecuador, Peru, Chile, and Argentina will all be stops along their route.
They accept the journey could put a lot to the test, including their relationship.
And coming from Aberdeen, they will take supplies of the humble buttery – the famous long-lasting local delicacy made of lard, butter and sugar, which is also known as a rowie or Aberdeen roll – to help keep their strength up.
“One of the most common questions we get asked is how we’re going to charge the car in the polar regions where there’s no electricity source,” Mrs Ramsey said.
“There will be a wind turbine and full double solar on this device which will be towed along, harnessing the renewable energy sources – the wind and the sun – to power the car.
“That has been really challenging, innovative, pioneering – it’s never been done before.”
She explained: “It’s to dispel common myths that people have when they question electric vehicles – things like range and how far can they go.
“We are putting the car through the harshest of environments – minus temperatures and extreme heat – so we’re really pushing the car to its limits and seeing what capability it has.”
Large tyres have been fitted to the vehicle in a bid to cope with harsh terrain.
There are also some mod-cons, such as a coffee machine in the boot. And there is a drone launcher, so the couple can film their journey.
