What TheGreeFa does and why it is needed

Today, greenhouse horticulture is related to the highest productivity of all common methods in agriculture. The energy consumption, especially for heating purposes in Central Europe are still high, while in Southern Europe, growing water shortages will force to use seawater desalination, which may also cause a quantum leap in energy demand.
TheGreeFa proposes solutions for greenhouse farming that recover the latent heat of the humid air, that otherwise is not used, and pure water from the humidity.
