I understand that it is not ‘practical’; that is not what I am asking.
I understand the sheer distance and time frame involved.
I also understand it is possible to launch things outside of our solar system.

Is it the ‘functionality’ of a device over many, many of years in the environment of space? If so in what way?
Is it the ability to ‘hit’ a target you aimed at many, many years ago?
Is it some other limitation?

I had sort of asked an ‘aiming’ question a while back and think it might be a bigger limitation than physical durability. I was thinking you could perhaps figure out a way to accelerate your load on the front end and set up some sort of permanent ‘drag’ device so that it would match speed with your target by the time it arrived.

To limit all functions to the front end of the journey so you wouldn’t have to perform some function en route or at the end. Slow yes, but I’d give it more chance than a flip and deceleration or course correction a thousand years from launch.
Zero-one: I don’t think I’d put biological creature on/in it with current technology; we really haven’t even ironed out travelling past the moon there I think.
Mike: Okay, so maybe "drag" was a poor choice of words. Would a "very small particle beam mounted on the nose" that had been set up to run continuously be a better choice of words?
Or, some sort of large surface that could use the impact with minute amounts of things over thousands of years to slow your progress?

1. Solar energy is not cost effective due to the cost of equipment and the cost fossil fuels needed to create solar energy cells in the first place. If you were to install solar panel on an average home in Phoenix AZ and you calculated the cost + fossil fuels used in creating the solar equipment it would take from 5-8 years to show a profit. Other cities that get less sun than the desert would take even longer and the cost would go up as you also calculate Maintenance dollars.

2. In order to generate enough energy to effectively curb our need for fossil fuels would not be economically prudent or reliable with the given solar technology as we know it today.

3.Hydrogen fueled cars and and big trucks is the main target of defeating the need for foreign oil. Solar energy will never be able to generate enough energy to supply hydrogen refueling stations.

I’ve been looking for a good Space game, preferably a strategy game. I have Sins which is a bit light on social development and trading, and focuses more on military. On the other side of that, Galactic Civilizations 2 is pretty cool. It has a much more robust Social and Planetary Development…. system shall we say? And it has the ship builder which makes battles very customizable. However battles seem to be illogical, like when a ship flies past its target and proceeds to shoot through itself, besides the battles being too short. I was wondering if anyone knew of any game like these two.
