The gas around the balloon is applying pressure to all sides of the balloon. However the force being applied to the bottom is greater than the force at the top. Now when the balloon is less dense than the air around it the weight of the gas inside it is not sufficient to cancel the upwards force of the air pressure under it. The balloon will then lift.

I'm guessing you have a compiler. If you don't download Visual Studio 2010. from here: http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express

Follow this series for learning C++: http://www.youtube.com/watch?v=tyVhn0FWWB4

then for assembly heres a pdf which pretty much contains alot of what you need to know: http://www.drpaulcarter.com/pcasm/

C++ has a cool feature called inline assembly which allows you to write assembly in you C++ code but you won't be doing anything like that anytime soon.

I'll be learning C++ then assembly because my current project requires that I do many small operations. Currently though I only know C#.

oops I feel dumb for calling it tidal lol. I have another one im working on that will store the energy in case the waves die down.

i thought about adding another float that the buoy looking one would pull down and the upward force of the float would drive a gear box hooked up to a pump that would suck air from the buoy looking float.

That way when the waves die down for a while you still have the other float powering the system while the buoy looking float has stopped moving.

I thought about that being a problem.

Would this be practical for use in an underwater habitat?

not only that but they should make it heavier. The only way for it to stay submerged it seemed was to force itself down causing huge amounts of drag.

I'll just leave this here.

I just found out how surprisingly well the Google speak feature works.

Well here it is 2900 x 1950

whatever needs cooling down. I thought with all the shit going on heat would eventually build up in the station and you cant cool it down by means of convection since were in space so you need to expel it as radiation this can be done with a vapor compression cycle which compresses a fluid more and more as it flows along the heat sink causing it to concentrate its heat energy on the outside of the coil system. which causes the material to glow from being hot releasing its energy in the form of radiation.

I've already tried compressing to level 9 its still 3.12 MB the effect i added must be very bad for compression.

>>3405921

I was just about to make that! heres a cool effect that seemed to fit right.

Had to save as jpeg as png was too large

no because on one frame the ball could be on one side and the next frame the other side.

ah what the hell or he could just sacrifice a slight bit of accuracy for simplicity whatever works. I just thought for something like this he would want very accurate collisions.

>>3403466

what are you talking about ive made a couple of games and found these worked out to be good solutions.

I think it would be better if you had an algorithm that solved the entire resulting collisions before the ball even moves. It would make the collisions much more accurate. or you could slow down time in the game so that when the balls do overlap they do so very little.

Has /sci/ thought about creating an institution.

next one should be a giant gif

What do you guys think of putting the shuttles on the deep space vessel

I'm using GIMP but Windows Paint will work. GIMP though has taken me a while to learn but makes things easy with the use of layers and some really cool image editing tools.
