"Two SunEdison employees and six Vestas employees work at Bull Hill daily..."

"An average [311 foot] turbine climb takes around 10 minutes and is performed two to four times per week."

Hypothesis https://hypothes.is/a/4pSbWRxBRZS9EU0rVaL79Q
"Forexample, in a 2–MW wind turbine, the weight of the rotorand the tower is typically about 250 tons [10]. As reportedbelow, a kite generator of the same rated power can beobtained using a 500–m2kite and cables 1000–m long, witha total weight of about 2 tons only."
Is this a reasonable claim?

The second half explains several results

"in a 2–MW wind turbine, the weight of the rotor and the tower is typically about 250 tons [...] a kite generator of the same rated power can be obtained using a 500–m2 kite and cables 1000–m long, witha total weight of about 2 tons only."
