They’ve got a quite unusual stove that’s got a large battery in it so that it can operate when the power is off, and doesn’t need the installation of a 240v power connection. This avoids the cost of an electrical retrofit of old apartment buildings, which otherwise costs far more.
If you’ve already got your home wired for 240v, you can get an induction stove for far less.
These battery-equipped stoves are expensive right now because they’re being made in quite small numbers. The parts needed are coming down in price quite rapidly, so I expect to see them sold in the $2000/unit price range within a few years.
If you have used a gas stove regularly, your health has been impacted to some degree, that is simply what the research shows.
Food lasts 30 seconds, health problems from gas stoves are over the course of many, many years. OP never once argued against your research, they simply made the claim that food is of better quality then when cooked on a resistance stove, which is true.
Have you ever actually cooked on a resistance stove?
