Doesn the huge collector waste too much land?
Due to the low energy density of solar radiation all solar technologies have the problem of large-scale land use to collect a meaningful amount of energy. Contrary to other solar technologies the GreenTower uses 2/3 of the land not only for collecting solar energy but also for high-intensity agriculture. Due to four yields in the greenhouse against one yield in high-intensity open air agriculture the GreenTower will, in fact, increase production to 270% and add a virtual 170% to the existing highly productive land. In deserts the effect will be even stronger.
