Ion drive meets drone, as small plane flies with no moving parts
Oh wow, I hadn't realised that was possible at all!

Date: 2018-11-25 08:48 pm (UTC)To be most efficient, they'd need to ionize just the oxygen and not the nitrogen (as breaking apart N2 uses much more energy, and can cause NOx when it recombines), and use the ionized oxygen, accelerated to high velocity, to then accelerate the N2 as reaction mass at low velocity, giving a low total output velocity. This means a bare wire wouldn't work as it wouldn't move the nitrogen; they would need something like a jet engine casing in cross section, with the ionizer at the narrow part.

Date: 2018-11-22 04:58 pm (UTC)I went back to school after my test, and after school set off to drive home. I was waiting to pull out on to a dual carriageway - no pedestrians allowed. My side road joined at a steep angle, and I had to look over my shoulder for a gap in the traffic I could safely merge into. I spot a gap, start moving forward in to it, turn my head forward, and see a guy standing right in front of my car. I slam on the brakes and stop, having moved maybe a foot and a half tops, forcing him to sit on the bonnet. He'd been standing waiting to cross the road (that had railings up the middle!) right in front of my car - as in within a foot. He ran off immediately- climbing (back?) over the railings that were designed to stop people doing what he'd just done.
I think we both learned an important lesson from that near miss. At least, I hope we both did.
