Building sustainable off the grid commercial vehicles can be more fun than running them, the off the grid renovations of this 1971 Airstream, have been a large part of the business model, building off the grid and mobile means you get to really look into some cool new technology for sustainable living.
The latest addition to the Airstream is a deisel heater by Esberspaecher (Espar), it is proven technology for heating cabs in big rigs and deisel cars, super fuel efficient with a thermostat means that this baby is now equipped for four season camping
A fuel tank mounted on the exterior of the RV - will keep us good to go for long periods in the summer and will allow for winter use of the trailer - the heater is equipped with a thermostat run by the solar powered batteries which will provide an even temperature in the trailer. An exhaust neatly hidden on the side of the trailer and the heater neatly hidden under the custom sofa frame.
And while I won't be headed to Antartica any time soon with the Airstream - it's nice to know I could.

Polar Traverse Airstream - Technical Information
ZERO SOUTH means ZERO fossil fuels to the SOUTH Pole—two vehicles will drive to the bottom
of the planet on batteries and biofuels.
The Airstream logo features trailer being towed by a bicycle to convey a lightweight and durable
trailer. The Airstream was selected for these characteristics and overall utility.
The trailer wall insulation was retrofitted with an aerogel blanket called Spaceloft, made by
Pacor. The cavity beneath the floor contains five inches of spray foam.
The vehicle was built to operate in minus 60.
The vehicle features sophisticated climate controls and two ESPAR forced air heaters to warm the
The interior heaters run on renewable aviation biofuel known as Synthetic Paraffin Kerosene
(bio-SPK). This fuel has a freezing point of -65F and is produced from an EPA-approved blend of inedible oils (used cooking oils, yellow and white greases) using a downstream technology that has not been made public. The heaters consume one gallon for every six hours of operation.
The expedition takes place in December which is the warmest month in Antarctica. Typicaltemperatures in December are minus 20F and may get as cold as minus 44F.
