Tower of Power Charges EVs, No Grid Required
- bradley13 3y agoBack-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...
- Ekaros 3y agoThat seems kinda too fanciful. Wouldn't it make lot more sense to have the turbine separate and then maybe cover the parkin spots with roofs covered with angled solar panels?
