I think a more honest title for the article might be "I don't know much about the 1800s" Abusive comment hidden. (Show it anyway.)
Apart from, you know, the whole "can't steer for shit" aspect. It's ALMOST as dumb as a Segway. Almost.
"...a Heluim/Hydrogen hybrid gas with an atomic weight 150 times lighter than Helium alone." <-- what does that even mean? In any case, even going all the way to complete vacuum only gains you ~20% more lifting power than helium alone: you're limited by the mass of the displaced air.
Empirically, 45 large helium balloons can lift their own weight, plus about 8 pounds. The balloons shows are substantially smaller, and there's only 10-12 of them. So, a maximum lifting power of ~1 lb.
If you want to argue that the desk, titanium cleat and laptop collectively weigh less than 2 pounds (since half the weight is on the Jenga blocks), go ahead.
