Talk:Solar updraft tower

Is there an error here?
"The chimney had a height of 195 metres (640 ft) and a diameter of 10 metres (33 ft) with a collection area (greenhouse) of 46 hectares (110 acres) and a diameter of 244 metres (801 ft)".

The area of a circle 244 m in diameter is 46k square meters or 4.6 hectares, not 46 h. 199.167.119.198 (talk) 15:00, 6 August 2021 (UTC)
