Nebula is constructed from aluminum, the most easily recycled of ls. It is also extremely lightweight which means that this surprisingly large space can be transported by a standard vehicle. No heavy machines needed. No fuel guzzling vehicles required.
The structure and materials are deliberately replaceable. This is a creative environment and can therefore be energetic. Fabric can be torn; the timber floor will get significantly damaged; aluminum panels will get dented. All of these materials are panelised and easily replaceable. No great effort or resource is required to mend or repair. Nebula is designed to be resource efficient and by that logic highly sustainable for a road vehicle.
On the roof is a solar panel, within the floor is a battery store. Nebula can collect its own power and run for over 4 hours at night with projectors and lighting working at full.
Nebula was never going to be made out of recycled timber, nor was the vehicle that towed it going to be hydrogen powered, however Nebula is a highly efficient structure built for a long adaptable life, thereby making it a highly sustainable road vehicle.
