The Silver Lady has a new rear tyre and has been fully serviced in readiness for the three thousand kilometre ride next week. She feels as eager to go as I. As I will be camping out on the way, and as I want to be well rested and alert, I gave a lot of thought to my sleep problem. I learned that a battery to power the CPAP machine for just two or three nights would cost me about $580.00. However for just $140.00, I bought a transformer that will power my schnozzle nozzle from a standard 12v battery. I tried it out using an old dying car battery from my Camry that I replaced earlier this year. I have kept it charge against a possible emergency. The system works fine. But I was not enthusiastic about lugging an old car battery on the back of my bike. So I bought a small motorcycle battery, less than a fifth of the mass of the car battery, and which will fit into one of the side pockets of my pack. I also bought a solar panel, which, mounted on my swag, will trickle charge the battery as I ride. One thing I am expecting is plenty of sun.
The battery cost $70.00. The solar panel $45.00. So for less than half the cost of a ResMed battery I have rigged a system that should give me similar or better results.
I shall report in due course, with pictures.
