Elon Musk, Silicon Valley’s poster-boy genius replacement for the late Steve Jobs, rolled out his PowerWall battery last week with Star Wars style fanfare, doing his bit to promote and support the delusional thinking that grips a nation unable to escape the toils of techno-grandiosity. The main delusion: that we can “solve” the problems of techno-industrial society with more and better technology.
The South African born-and-raised Musk is surely better known for founding Tesla Motors (TSLA), maker of the snazzy all-electric car. The denizens of Silicon Valley are crazy about the Tesla. There is no greater status trinket in Northern California, where the fog of delusion cloaks the road to the future. They believe, as Musk himself often avers, that Tesla cars “don’t burn hydrocarbons.” That statement is absurd, of course, and Musk, who holds a degree in physics from Penn, must blush when he says that. After all, you have to plug it in and charge somewhere from the US electric grid.
Only 6 percent of US electric power comes from “clean” hydro generation. Another 20 percent is nuclear. The rest is coal (48 percent) and natural gas (21 percent) with the remaining sliver coming from “renewables” and oil. (The quote marks on “renewables” are there to remind you that they probably can’t be manufactured without the support of a fossil fuel economy). Anyway, my point is that the bulk of US electricity comes from burning hydrocarbons, and then there is the nuclear part which is glossed over because the techno-geniuses and politicians of America have no idea how they are going to de-commission our aging plants, and no idea how to safely dispose of the spent fuel rod inventory simply lying around in collection pools. This stuff is capable of poisoning the entire planet and we know it.
The PowerWall roll out highlighted the “affordability” of the sleek lithium battery at $3,500 per unit. The average cluck watching Musk’s TED-like performance on the web was supposed to think he could power his home with it. Musk left out a few things. Such as: you need the rooftop solar array to feed the battery. Figure another $25,000 to $40,000 for that, depending on whether they are made in China (poor quality) or Germany, or in the USA (and installation is both laborious and expensive). Also consider that you need a charge controller and inverter to manage the electric flow and convert direct current (DC) from the sun into usable alternating current (AC) for your house — another $3,500. So, the cost of hanging a solar electric system on your house with all its parts is more like fifty grand.
