one balloon, rigid triangle frame
hang a triangular frame, approximately equilateral, under the balloon.
Attach it to the balloon by one vertex, lower triangle edge to be horizontal. Rocket on one side, counterweight on the other side.
Similar to original Register idea except a single beam attached to string at the center is never going to remain horizontal
Standard US Recharging is different
UK mains are 200V or 200V or some such?
US are 110V~120V "standard". Then with a 15A circuit you are way behind the 3kW you quoted.
You can get 20A at 115V pretty easily, and any new house now built will come with some 220V plugs for oven, clothes dryer, etc. Not sure if that's usually 15A, could be higher.
So electric car owners in US are told "special equipment" might be needed.... and I assume that's a 220V socket installed in the garage somewhere handy.
The article quoted "US standard" mains so is technically correct
Google "Interdata Computers" for more info, Interdata was acquired by Perkin-Elmer.
IIRC, Tektronix's 4081 graphics computing systems used Interdata CPUs; Cannot remember what OS was on that beast however.
