Nicholas Meier Posted over 2 years ago GREEN TECHNOLOGY + HYDROPONIC FARMING: We can do it right now! Let's go! Pro Hydro! Yes I am here, thanks. Speak again on how farmland is valuable. Remember, we are in North America, farmland is cheap here. Drive across the prairies here in Alberta and you'll see how much abundance we have. The building is energy intensive by how much energy it is going to take to build a tower like that. Contemplate not only the construction of the tower, but also the energy required to make advanced materials like nanotechnology. Large microscopes that look at particles take a lot of energy, especially since they don't have a way to easily replicate and build carbon nanotubes. Vapor deposition take a while. And still on my argument, that free energy you speak of is nowhere near enough to power something of this magnitude. Fundamental laws of physics and heat transfer. The building radiates energy and will at an impressive rate when exposed to cold air outside. There's a lot more to that.
