So in short, I have been living the car life instead of the van life for about 2 years now. (yes, I am living in my car). I guess I found myself in this way of living in order for me to earn and save a tonne of cash without the limitation and responsibility of rent , bills, etc. The long and short, is its really worked well.
There is however the limitation that, my diet currently runs on tescos, as well as tinned foods etc. While quite healthy, its expensive, probs spending about £15-£20 per day, as I work about 60hrs/week and also attend the gym 4-5 times a week. With this said, I know that I could probably half these costs, if I had access to my own basic facility whereby I could grill and fry my own food, as well as power a fridge unit, which could hold enough basic food items for 3-5 days e.g. steak, chicken, salad, etc.
Everyone talks about vans, which dont get me wrong, is a good idea, if you can afford it and have the resources, however, the car life is something I have grown into and so I want to build on this, instead of changing my vehicle. With that in mind, as far as cooking and food storage goes, I have considered the idea of purchasing a mini camping trailer, and fitting it with a basic foldable worktop, as well as a compartiment for a small water bowser and a section for a fridge. The fridge (I imagine), would be powered by the battery which would draw its energy from the daily driving I do per day.
Now this is where I need expertise:
-if I wanted to power a fridge which ran on 60watts, could operate through 12/24v and had a DC of 4.5/2.2A, would driving say 10-20 minutes per day, be enough to power the battery and the fridge for 24hrs (working on the basis that I do about 10-20minutes of driving everyday).
-would my battery for the fridge, need to be connected to the main car battery in anyway? I am assuming not, as because the trailer, the fridge and the battery are their own self contained facility, I would not need to do this.
-lastly, is there an apparatus, that can be attached to the wheels of the trailer, that transforms the kinetic energy of the wheels moving during transit, into storeable energy in the battery?
Thank you for reading, if someone can help me out with this, it would be a great help. The last 2 years have been pretty interesting, this project, would be a great advancement.
