My apologies for lacking common sense.
I bow to you O Great Desalinator......
Just out of curiosity though what are your qualifications and field of "expertise"?
Below is a standard desalinator btw
As you have probably read in the wiki you need several freezing and thawing cycles for it to be drinkable.
1)You will need the machine to work continously not in batches.
2) At such a great vacuum a huge amount of salt will contaminate the vapour i.e. unusable.
3) The remaining sea water in the...
Look man I'll tell you as simply as I can.
Forget the heat source. For you to get pure ice you need pure water vapour. You CAN get pure water vapour from sea water but it will be miniscule. So you increase the rate of evaporation by increasing the vacuum, at the cost of purity.
I've detailed the...
ASSUMING that these blocks are free floating in space.
Power is the RATE of doing work. Since the first block moves faster it requires more power.
Work done = force x distance
Now distance is the same but did you give the same force to both blocks?
