Basically my idea is to use solar panels to power rotating mirrors that follow the sun. The mirrors reflect the sunlight to a large "Still" filled with salt water. The still heats up and the water evaporates leaving the salt behind. The water is collected and distributed for drinking and the salt is cleaned out of the bottom of the "Still" through a hatch. The picture is very... Kindergartenish, but it was all I could do spur of the moment. I would appreciate opinions, ideas, and constructive criticism.

Responses wouldn't necessarily need emotions. Responses could be programmed by actions alone. For instance psyche evaluations could tell us how someone would react to most situations.

Then digital immortality is a possibility?

I've been trying to find plans for a smaller Tesla Coil. All the plans I find online are for a price or not accurate.

First of all I am a huge Battlestar Galactica fan, so I watched Caprica. I was disappointed, but the program that made the original Cylons made me think. Would it be possible to to create a Digital Double of a person using personality tests, and a lifetime's worth of journal entries?

Do you know the calculations for figuring out the differences between time with no gravitational potential and say earth?

The greater the gravitational field the slower time, the less gravity the faster the time. If a certain area in space could be cleared of all gravitational effects, how would that effect time?

he was walking.

Theoretically, if money and resources were unlimited.

What we could achieve in the here and now if money was not a factor.

Well so far Phi For All is the only one on topic here. The topic is supposed to be "How To Make A Flying City" and nobody is discussing this. So here are some questions. What propulsion system would we use? What type of design? How would we make it? What would we use to make it? How would we power it?

1. Some day we will have the technology to send MILLIONS of people into space daily. That is what this topic is about the future not the now. 2. When we have the technology to build a city that can travel our solar system and sustain itself why would we have to send a rocket to it? A true self sustaining city would have the ability to make its own rockets (why in the future we are still using rockets I don't know.) Most cities have FACTORIES and they will be able to make their own Rockets. 3. As too already having weather stations and observatories, I know we have them, BUT we don't have them orbiting EVERY planet and moon. So unless our future space travelers only want to go to the places we have already seen we will need more. 4. The definition of a "Space" mine; Is a mine IN space. If we have city ships IN space why would we need to send anything back to Earth unless they needed something? All they would have to do is orbit a asteroid they are mining and send the materials to the city ship. 5. You want proof that a self sustained civilization is possible? Look around. All of humanity is a part of a self sustained civilization in space. That is unless you know of some outside source that has been sending us things? The purpose of this topic was to see what people thought about our future space exploration, and how we would be doing it. For some reason it seems you believe that I was planning on building one in my backyard tomorrow. Again this topic was about our future not our present.

Lol. A city that flew in the clouds would be amazing, but I am talking about orbital cities that could be used as bases and maybe even colonies throughout the solar system.

Over Population You can keep building up until you reach eye level with God, but eventually you will have to expand horizontally. Our over population will eventually lead to over exhaustion of our resources, which will lead to dramatic rationing of food, water, and air. If we had self sustaining cities in orbit we wouldn't have to worry about it. We would just build more cities and send them on their way. Launching Spacecraft You honestly can't tell me it would not be easier and cheaper to launch from an orbiting city than from the ground. On average it costs $450 Million per mission to launch from the ground. http://science.ksc.nasa.gov/pao/faq/faqanswers.htm Weather Stations and Observatories Weather stations and observatories in orbiting cities most likely would be common place. Not only would they be beneficial while in orbit, but once they left orbit to go to Io, mars, etc. they would be a necessity in studying other worlds and their surroundings. Space Mining Space mining is something we are going to have to do, the Earth just doesn't have enough resources to sustain us forever. Space mining would be ridiculously costly if every time we mined something we had to send it back to Earth to process just to send it back into space. If we had refineries and factories in space near the mining, long term costs would be a lot less. Flying cities could be the first step to long term colonization of space. If we could build cities in orbit and they could sustain themselves for long periods of time then colonization of other places would be easier to comprehend and manage. For instance, Mars is a very nasty place with all of its dust storms. http://science.nasa.gov/science-news/science-at-nasa/2001/ast16jul_1/ Storms that would make exploration and colonization a real hassle, but if explorers and colonists were safely tucked into orbit storms wouldn't be a bother to them.

Very true, but there still are a endless number of things we have not even dreamed about let alone tried.

Over population, platforms to launch spacecraft, weather stations, observatories, etc.

To live in a flying city would be truly amazing, but how would we make it fly, power it, and control it?

Snakes take up to much room. We would need miles of them and they would cause problems for ships.

That could work, but we need to look at power consumption too. How much power would something like that take?

We couldn't build a Hoover dam in the Atlantic ocean or in the English channel. We need a better way to collect the power of the currents and tides.

With all the power behind tides and currents, there has to be a way to efficiently harness this power and put it to good use. How would it be done?

In oriental hammams you don't get clean. you are still drenched in your own sweat, and the sauna and cold water idea wouldn't work either. The point of a sonic shower is a quick and efficient way to clean yourself without water.

There have been experiments with boosting brain power over the years. Perhaps a artificial organ, brain lobe, or the right chemical combo could help project thoughts, but we would still need a way to receive the thoughts.

Which is affected by matter density.
