> which makes planes expensive to make, and expensive to maintain Understood. Though as the comparison link mentions, there's another important cost - "limited utility has kept production levels low enough that it has been impossible to amortize development costs sufficiently to make GEVs competitive with conventional aircraft". I don't pretend to have more than a surface knowledge about topic, but when the idea has been around decades, developed and promoted for decades, and is still only a niche mode of travel (along with hovercraft, hydrofoil, and flying boats), that tells me the doubts aren't simply from those who "complain about anything new". > The statement was that its better than planes or (motor) boats. Sure. My comment was to point out how complicated the full calculation was, because it should include the electric ferries that becoming available, and not limit itself to motor boats.
