Have to be careful with methanol, because it is flammable.
And methanol burns with almost no visible flames.
Building a large device with the working liquid as methanol, the device
becomes a methanol storage by legal definition, and requires permits too.
Water solution of baking soda is not explosive, not flammable and not poisonous.
Same thing with the carbon dioxide, not flammable, not poisonous, not explosive.
Large device can be built, and the working liquid and gas does not leave the device,
just recycle within a closed system. Breathing CO2 only is deadly, but in an open,
well ventilated area with lots of O2 available to breath, CO2 will not poison a person
as ammonia or CO would.
There was some discussion of highly technical type of the working liquids, and the
term ‘binary liquid’ was coined. A binary liquid is a theoretical, ideal liquid.
In my opinion, the transition of CO2 from gas to liquid is an approximation
of a working binary liquid, but it requires more complicated equipment to withstand
1000 psi pressures.
The CO2 transition from gas to liquid would still work at very low temperatures, -78 deg C.
Theoretically makes energy available at very low
temperature, such as arctic conditions, where seawater temperature is about -3 deg C and
surface temperatures can be -40 deg C. (I would like to stay on warm climate.)
It is controversial, and lots of discussion can be done about it. And in small amounts,
even diet coke can be used as a working liquid, and the carbonation would be the working
gas. I did build a small device with diet coke in it, and it worked.
The efficiencies and practicality of the device is a different question, and those would
have to be developed. It is a benign hobby. Coke bottles, PVC pipes and diet coke.
When all goes bad, I just drink the diet coke. I like low calorie liquids to drink.
And this would be a future development, just like 3D printing with sea water with solar electricity.
For the start PV solar panels are good enough.
I am focusing on the immediate things, tires, ringweaving, and sailing.
