Bizarre 460
Japanese company PowerX is moving ahead with its strange plan to build a "mobile power station" in the form of a 140-meter (460-ft) electric "battery tanker," which will carry 241 megawatt-hours of renewable energy across the sea over short distances.
The idea here is simple enough: renewable energy is often generated a fair distance from where it's most needed, so let's build an electric ship full of batteries, and jolly well ship it there.
Why not just put down an underwater cable? That's a fine question. PowerX points out that Japan is surrounded by deep seas, and prone to earthquakes, and says in a press release that "the ship-based solution resolves issues such as long downtime from undersea cable malfunctions and repairs, as well as the high costs associated with ultra-high voltage connections and substations."
