The Boring Company is getting decently well-capitalized on the back of sales of its flamethrower (yes, flamethrower). The no-doubt overpriced piece of knack, which can be make yourself at home using likely around $30 in parts, is selling for $500 and has already netted Elon Musk’s digging venture $7.5 million.

That’s after just over a day of being on sale, and not counting the revenue from fire extinguisher sales (those sell for just $30, which is itself also overpriced). All told, Musk says he’s sold 15,000 of the flamethrowers thus far, with only a total of 20,000 available in total during the sale.
