    Desalination new method

    Well..... 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

    Atmospheric CO2 removal technologies?

    Haha no I don't believe that. Of course its the regeneration of used O². It is largest forest in the world and does contain almost a 3rd of the world's trees.

    Atmospheric CO2 removal technologies?

    I'm talking about scrubbing with amines or metal hydroxides. Though they get degraded really fast. I read somewhere that were trying to create new scrubbers with what else- carbon nanotubes.

    Upgrading a 12V Alternator to Produce a higher output Volts

    Haha is this a perpetual motion machine we are talking about?

    Upgrading a 12V Alternator to Produce a higher output Volts

    The max. power being generated by your alternator is constant. You can play with the voltage at the expense of current. So charging time will be quite high.

    Man I remember that quote verbatim from BBC's Planet Earth. i would assume that they do not lie.

    Step up transformer? Turn ratio about 16.

    Desalination new method

    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...

    And btw berkeman your a great mod. Also is that you on the bike?

    Desalination new method

    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...

    Is the energy output of an engine constant?

    By Merlin's Beard!!! What an answer!!

    Is the energy output of an engine constant?

    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?

    Atmospheric CO2 removal technologies?

    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...

    Is the energy output of an engine constant?

    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...

    Desalination new method

    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.

    Desalination new method

    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...

    Could this be possible? water underground

    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.

    Pressure measurement

    Well I have seen the standard 4mA-20mA sensors give exactly the same readings at 1m and 200m because of the corrected resistance value for such a long wire.

    Could this be possible? water underground

    That pressure has already been utilised when the well has filled up naturally to a certain height. It's about the additional pump required to pump it from that free surface depth.

    Pressure measurement

    What kind of measurement are you talking about? Electrical sensors? Mechanical Sensors? Liquid or gaseous?

    Could this be possible? water underground

    Russ i thought about this too but I'm not sure if the atmospheric pressure is directly or continuously acting on the water table. Maybe it would be much less than 10m head. Any insights?

    Could this be possible? water underground

    This is the principle utilised by bore wells all over the world. Nothing crazy about it.

    Why 220V/50Hz or 110V/60Hz?

    Oh ok. That has already been done to death on the forum lol
  26. Rippetherocker

    Why 220V/50Hz or 110V/60Hz?

    There ARE other standards... Like 440V/60Hz 380V/50Hz. Whats stopping a uniform code is just human laziness and rigidity.

    Refrigerant for AC and refrigerator

    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

    I need to anchor a raft

    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. If...

    High Speed Transit Help

    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 500000m= ½a(600sec)² So acceleration is around = 2.77m/s² That is doable for line A. Note that as line distance reduces...
