The teardrop is a minimalist design, I am looking at stretching the envelope for wild camping, how do you eradicate any need for outside power. As a survival pod a tear is fantastic
Shelter and warmth
Insulation, perfect insulation would mean heat once to right temp and then never require heating or cooling again, unfortunately we need to breath and get in and out every now and then, but with good insulation we can virtually remove the need to heat, one body produces 300 Btu's as a minimum, with 2 people subzero temperatures should be easy to cope with, candles could be employed to good effect. Also working on a micro solid fuel heater for tiny spaces.
Could I ask those that have an insulated tear do you ever need to use a furnace? If you do, could you give me an idea of the outside temperature, the level of insulation? how long you need to run for etc.
Cooling, several Ideas I have to look into here, micro breezes to assist the bodies natural cooling, shading and obviously the insulation will help.
Water, I favour a top notch water purifcation system like the Nature pure, this means that in a pinch even dirty ditch water can be made safe, clear and tasty, thus requires a decent electric pump but as its such an infrequent use solar power no probs. or revert to hand or foot pump
Light, Led's for micro power consumption, candle if heat and light required.
Cooking and hot drink making, small solid fuel, solar ovens would work in certain countries (all countries for certain parts of year) any of these methods can also be used for hot water.
Only the first few idea's thrown out here for feedback
