Back-of-the-envelope: The rendering looks like a max of about 20kw of solar cells. If they think they can produce 70kw, they are counting on quite the wind. Their predicted annual production corresponds to 26kw, which is a lot more believable, but still assumes a lot of wind. "Because of its slow-but-steady generation, a tower could link to the grid with 240-V, single-phase power that’s available anywhere and everywhere, rather than paying to upgrade and install pricy 480-V, three-phase power." If it's going to be single-phase, it's going to be pretty slow charging EVs, which is supposed to be its main purpose. Anyway, 3-phase power is hardly anything unusual, when you're talking about generating tens of kilowatts. Feed in up to 70kw on one phase? I don't think the power company is going to like you for that. "...six charging stalls and plugs, at an estimated price of about US $80,000 * * * ...the tower can generate electricity for as little as 4 cents per kilowatt-hour" Oooo, I love math. Purchase price $480000. Annual output claimed to be 234000kwh. Expected cost of four cents per kwh. 234000 * 0.04 = $9360, so they are expecting a tower to have a lifetime of...more than 50 years. Riiiiight...
