One thing that always bothered me about airplanes is the energy used to take off. On aircraft carriers, they use a launch device, allowing the airplane to "push off" against the carrier. Compare this to airplanes taking off on land, they just nail the throttle and take off by pushing air...

A land-based launch system would have a lot of advantages; lower peak power would be needed from the motor and batteries, the engines could be made smaller, the energy used to take off doesn't have to be stored on the plane, everything gets lighter and more efficient.

My 1700x build for video processing has suffered major instabilities -- app crashes and BSODs -- memory corruption type errors. I went through 4 different types of DDR4 memory until I found some that works, even though it isn't on the ASUS's Qualified Vendors List. My advice is to make sure your RAM can do 15-15-15-36 timings (or better).

The filter checkboxes are a bit weird, for example elements (such as br and img) which are both self-closing and inline only show up if both self-closing and inline are selected, instead of one or the other. Also there are several elements such as li which are not categorized and show up even if no checkboxes are selected.

Publicly shaming Gigster like we're doing here should help.

To a large extent, my daily driving consists of going to the same 5-10 places. I'd like my car to watch me drive somewhere and then just do that, with minimal improvization. For example, in order to enter my driveway I have to swing wide into the oncoming lane to make the turn. When I drive to work I avoid the same potholes all the time. Pretty trivial to just record my driving once or twice, and replay that back with minimal improvisation.

Fair point. You don't measure fuel economy on cars by running them on an oval track with the accelerator pinned.

Oh yes, and nobody cared about the performance aftermarket (basically anything you do is going to violate emissions standards) until Harley started selling bikes already modified for "racing".

I dropped 20 lbs off a 330lb bike (and added about 5hp) by replacing the heavy dual exhaust with a single Ti/carbon pipe, and reprogramming the ECU. I'm sure the manufacturer would have loved to give me a 310lb bike that made more power if they could. (and before you ask, no it's not loud, I hate loud pipes)

Incidentally, the exhaust/ECU upgrade was done by the local shop when the bike was purchased new. Basically the same as what H-D was doing.

Anyway, what H-D got popped for is arguably less egregious than what VW was doing. They admit that the modified bikes bypass emissions requirements, whereas the unmodified VWs didn't meet the requirements and had to cheat to pass inspection.

One megahertz is more than enough. That's enough power to compare like three-thousand integer values per second, which is way more than a human can do. We've got these guys out there, and they've got 3 gigahertz and more! And they're not even using them! They're playing Candy Crush for gosh sakes!

These people are wasting energy and these super-powered CPUs are a potential fire hazard and we need better regulation enforcement now!

If we restricted high-powered CPUs to people with a license and a documented need, the world would be a safer place for me.

...In all seriousness, 1hp is not serious shit. And motorcycles are significantly faster and more dangerous.

You rebel!

Unless you're assuming an awesome future with net guns fired from pirate drones, downing the Amazon drones and stealing their wares, this is just the same package theft issue that already exists.

Probably about 300-500 watt-hours of power and approximately 20 watt-hours per mile, so 15-25 miles.

My favorite sources of information about e-bikes come from endless-sphere.com, electricbike.com, electricbike-blog.com, and the /r/ebikes subreddit. Also I've obsessively watched almost every video with "BBSHD" in the title on YouTube in the last several weeks. I will say that the technology is moving pretty quickly and the state of the art today will be the underpowered overweight crap of tomorrow. There is a LOT of room for better technology and the price can come down further as well, all it'll take is an expanding market and competition to bring new innovations to market.

In my opinion the current generation of mid drives are better than the vast majority of hub-drive motors, whether we're talking about the Bosch or Yamaha or Bafang etc... "Better" is a very slippery word. The Gazelle bikes have the Bosch mid-drive system which has torque sensing, but only puts out 250 or 350 watts and your bike cost $3 or 4 thousand dollars. Considering the moderate range and instantaneous power, while it's in line with similar bikes, I feel that it isn't a good value overall. Once bikes with this kind of performance are readily available for, say, $1200, the world will bend around them. But not before.
