Comment on Floating turbine towers above — the S1500 hovers to harvest wind at 131 feet
Delilah@lemmy.blahaj.zone 4 hours ago2"Ø UHMWPE rope has a breaking strength of ~375000lbs weighs 94lbs per 100’ so about 4700lbs for 5000’
That said I have know idea if 2"Ø is the correct diameter rope to anchor one of these balloons.

If you’re adding two strand #2 AWG wire it’s about a half pound per foot so another 2500lbs which means the floating windmill has to support 7200 lbs in addition to the weight of itself.

From the article the turbine unit weighs 2204lbs so that’s ~9400 lbs total. Omni calculator says you need 348,436 standard 11" party balloons or 3,979,252 litres of helium to get off the ground and 423,779 party balloons to reach 1.5km altitude.

It can’t weigh 2,204lbs if it floats it should weigh approximately -7,200lbs if it’s going to carry the cable and rope.

I’m assuming that’s the weight of the turbine without helium in the balloon.

Could you not add wings for additional lift?
