The design this appears to be a "high" pressure balloon. Nasa is currently researching ultra long duration balloons.

During the day the sun will heats the helium causing it to expand and the craft floats upward.
During the night the helium cools causing it to contract and the craft falls downwards.

The whole thing looks too heavy to even get off the ground. :(

You don't have to know how the computer works, just how to work the computer.

Working...
