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?
Despite being an engineer and having an interest in this I have found that the easiest and best approach is reforestation.
The russian taiga frozen all winter comes alive in the summer and replenishes the earth's oxygen content by 1/3rd !!
Zero capital.zero maintainance.
Other than that...
If an engine is rated it is for a particular power at a given constant rpm at a given torque.
For.e.g. 12000kW at 127 rpm
600kW at 900rpm.
Or 120kW at ? rpm
A car at 100kW can run with lets say 500rpm for x liters of fuel. Same car will get only 400rpm at an incline for same fuel and power...
And just to add we've all had that eureka moment when we thought we could change the world. We know how you feel! The people here on this forum are "experts" so heed their advice.
P.S. - Anyone who calls himself an "expert" is automatically stupid in my book.
I'm not an expert as berkeman said lol but i do work on such systems on a daily basis.
Standard plants are maintained at 90% vacuum for a reason. It keeps the boiling point at around 50°C.
Do you know why? Its because at greater vacuum the water will flash almost instantaneously and salt...
10m is the theoretical limit at 1atm. Practically vapour locking will cause a loss of suction much earlier. Think maybe 7m in reality.
Though I'm getting the suspicion you are after a perpetual motion machine.
You can but it is not advisable. Systems are designed keeping the refrigerant properties in mind. Their heat of vaporization, specific heat etc.
Remember a fridge cools to a much lesser temp. Than an AC.
unfortunately I'm unfimilar with domestic units
Use what the ancients used for thousands of years. Stone doughnuts.
Or concrete ones with metal for weight. Make several maybe 20kg each. If your need is a platform then tie it to a rope and throw it some distance away from a corner. Do the same at the other corners. Let them settle a bit.
Taking Line A of 1000km in 20min most comfortable would be constant acceleration and deceleration. So cover 500km in 10min then decelerate.
S= ½at² => 500km= ½a(10min)²
So acceleration is around = 2.77m/s²
That is doable for line A.
Note that as line distance reduces...
