Technically, how? The only scooter feature that comes to mind that sort of fits is that one's feet go inside the frame (but one also straddles the frame, so it's a draw)
tire size? probably not a scooter
engine performance? not a scooter
handling? not a scooter
clutch? I don't know. Maybe the Akira 'bike has a CVT?

It depends on where the motor is. If it's in the frame under the seat, I'd call it a motorcycle. If that's an electric motor directly driving the rear hub, it's a scooter (judging by the sounds from the movie, I'd say that's more likely -- there's an electric motor directly driving the hub).

That's just how cell phone cameras work. Things that are moving very quickly get strange effects applied to them since the entire image isn't taken all at once. I believe it's called rolling shutter effect.

I... what?

Classic cars are gorgeous, but for all their throaty V8 rumble car manufacturers struggled to make 150hp without throwing the biggest truck motor they could find at the problem. That's probably good though, because braking and turning were mere suggestions.

I get it. Economy cars all evolved to look like the first gen prius. But the circlejerk around classic cars just winds up lowering the resale value because you damaged the clearcoat scraping cum off of some dentist's Galaxie.

um excuse me posted:

Conversion losses. You are taking energy required to drive a valvetrain, which is a shitload by the way, and converting it into another form of energy, then converting it again. A traditional valvetrain takes mechanical rotation energy from the crankshaft, to rotational energy through the timing system, to rotational energy in the camshafts, to linear energy in the valves. It's all mechanical. With any type of independently actuated valve system, you require the crankshaft energy to convert into some sort of other energy, whether it's pneumatic, hydraulic, or electric. Then it needs to eventually be converted back to mechanical energy at the valves. Any conversion of energy has efficiency losses. There are at least two in a camless system where there is a comparatively small amount in a valve train. These rob the engine of energy in far greater quantities than you get with efficiency gains of independently operated valves. Especially when you have to compete with active variable cam timing on both intake and exhaust like modern cars have.

I'm curious, does the same apply for gigantic marine diesels that max out at like 110 rpm?

Those typically don't run at a wide RPM range, so having variable valve timing doesn't get you much. You just optimize for the RPM it's going to live at and don't worry about added complexity.

We were fighting with that at my last company. A lot of shipping contracts, especially for bulk cargo, are more profitable if the ship slow steams (thus burning less fuel) and arrives on time rather than running at the designed RPM and then waiting at anchorage for days. How much the ship slow steams varies by the terms of the contract. In theory, variable valve timing would buy you some more fuel economy there.

Also you could shift the ship into reverse without engaging a new set of cams.

Could you share more about this? This seems like awesome boat insanity poo poo which is...close enough.

I used to work for these guys: nautiluslabs.com

We'd tie into a ship's navigation system to get position, speed over ground, speed through water, wind, and as many other data points as we could (we'd also pull wind, current, and weather forecasts from NOAA). We'd also tap into the ship's engine and fuel delivery systems to get the fuel consumption rate and what kind of fuel the ship was burning. From that, and by knowing how low the ship was riding in the water, we could figure out how much energy was being wasted in the interface between the water and the hull, between the propeller and the hull, and we'd generate an empirical model describing how efficiently the engine could turn fuel into power at every speed. Less expensive ships use fixed pitch propellers that attach directly to the engine's output shaft, so the engine's RPM is directly related to how quickly the ship wants to move through the water. We'd work with the shipowners to figure out the peculiars of a ship's contract, and we'd provide speed recommendations: e.g. steam at 72 RPM across the Atlantic, then switch to 61 RPM at the Strait of Gibraltar. We'd update that daily based on weather conditions and how the ship was performing.

It took a little convincing to get the captains and engineers comfortable with changing speeds dynamically. I had some highfalutin' notions about variable valve timing to squeeze a few extra milijoules per gram of fuel across a broader RPM range.

Regarding reverse -- because these ships use fixed pitch, direct drive systems, you'd have to spin the engine backwards to reverse. To do that, you'd shift the camshaft so that its reverse lobes lined up with the valves.

I took a picture of this placard in the engine control room on a 20,000 ton chemical tanker while it was unloading molasses in Seattle. It was attached right above the engine order telegraph.



A different ship crashed into a pier shortly after we installed our system on it. We pulled the RPM data from shortly before the crash. At 30 second intervals, it looked something like 53, 35, 8, -7, -28, [crash]. Unfortunately I can't find the map I put together of that incident.
