The base of the pod, to which the axle and front electric hub wheel are attached, is going to be reinforced 50mm aluminium tube and 50x25mm aluminium box section.
The concept is that the pod is constructed in sandwiched sheets of bonded 0.9mm and 1.6mm aluminium (25 mm celotex is the centre).
So the pod consists of the reinforced floor, two sides (one with a door in), the curved roof and the stepped shelves (sandwich of 0.9mm aluminium sheet and 4mm corex) for the "kitchen" at the rear of the pod. I think this makes it a "monococ" pod!
The walls and roof will fix together with a plastic square/45 degree block connector that we are 3d printing - CAD drawing to follow
The floor will actually be made 100mm thick and will contain 4 "wells" with lift off tops. These wells will house a battery pack, water tank and the eletronics and controler for the front hub motor wheel, and a clothes storage area.
The mattress will sit on that floor. On the inside of the structural kitchen shelves there will be a little shelving and storage, some led strip lights, amd some power outlets both 13amp and usb, and hopefully I will be able to lie in bed with my tablet in front of me skyping away to my hearts content!
The roof will house a pop up perspex vent with inbuilt electric fan for ventilation.
The kitchen is accessed from outside the pod at the rear, a curved roof profile door that will be supported on 2 gas struts. The kitchen will house a small chiller box area, stowage areas for folding seat, table, pop up "loo/changing room tent" and for wash bowl, pots, pans, crockery, cutlery etc as well as the obligatory spice rack. The door will house led strips for lighting.
The outer skin of the roof and the kitchen door will be covered by solar panels linked to the battery bank in the floor compartment.
Our target weight including battery, solar, etc etc is 100kg, which is going to be tough to achieve.
The battery bank will be lithium ion and hold around 3kWh. This will be trickle charged at around 1-300w by the solar array, and can also be charged via a plug port on the side wall at camp sites etc. from any 13amp supply. This way spare bike and hub wheel batteries can be being charged up whilst I am on the go from the power outlets in the "bedroom" that are running via an invertor from the Pod's main battery bank.
The pod dimensions will be 2200mm long, 1250mm high (1450mm AFL including wheels) and 1050mm wide
The initial pencil sketch designs were mine, but the real work at this stage is being done by my eldest son Ollie who has spent the last 8 years being a motorsport design engineer at the top levels of Endurance racing (Le Mans) and before that winning the GT1 world championships!
