I absolutely love airships. Lifting body, flying wing, tethered, untethered, rigid exoskeleton, or fully inflatable. I could probably talk the ear off of anybody willing to listen.

Fill the 'ultra efficient' streamliner car with helium for even better mileage!

airship cargo capacity = density of surrounding air × balloon volume - mass of airship (which includes mass of the helium inside the balloon). This equation also works for boats but the volume would instead be the submerged underwater volume and the density of water is 1000 kg/m³. Simplified equation: cargo mass = rho × Vsub - ship mass A 1 ft³ cube is about the minimum volume needed for a boat to float a human. Since air is 1000x less dense than water, the balloon volume needed for a human to become airborne is roughly equivalent to a 10x10x10 ft cube. An interesting project would be filling an airfoil shaped balloon with helium/hydrogen/hot air so you can create a flying machine with two different sources of lift

Helium is a precious resource and although hobby and consumer use makes up for a very small amount of use please keep in mind its importance. ~that being said, have fun

Wait a tic, you're not using helium to aid in the life-sized rubber band plane right?

Think Flight
This doesn't happen every day.... but when it does it needs to be pointed out. Thanks to cal-tool.com/ for donating a not insignificant amount of helium for an upcoming project. The owner appears to love aviation as much as I do, and when helium is the right tool to make something go.... You'll meet them and see their operation in the upcoming video, in the meantime I would be grateful if you checked them out for any tooling and welding needs in the SoCal area.
