Naruto run. Don't even need to read the article. "Without external energy (but with external device attached)" is ... a bit disappointing. At what point does it cease to be running and start to be run-assisted catapulting? Or catapult-assisted running? It seems like more than just running .

I googled "Naruto run" and it's just... Anime characters running with their arms outstretched behind them. That's not what TFA is discussing, you should probably read it.

It was used in 2019 to storm Area 51.

Their model seems to predict a theoretical top speed of 18-20.9m/s (or 40.0-46.8mph, 64.8-75.2kph): https://www.science.org/doi/10.1126/sciadv.aay1950#F2 As much as I want to imagine people chasing down cheetahs, without empirical testing I have to admit I am skeptical of their claims.

Eh, I'm not worried about their top speed claims... I'd be far more concerned that you could reach those speeds, and the hospital bills incurred by the inevitable accidents. You're going to have to have a massive amount of safety gear weighing you down (thereby losing speed) to keep you from busting your head open like a rotten cantaloupe moving that fast. Velocity squared is a bastard.

Earlier quoted context omitted.

I want to get somewhere faster with portable tools. Used to skate, but annoying to take skateboard everywhere. I live in SF, so bike gets stolen. Currently use Lyft e-bike rental but ideally have similar speed but backpack-able portability. Honestly, maybe I wear cooling vest and just jog to work. Walking too slow: 15+ min / mile.

What about roller blades?

I am an excellent ice skater and decent, not great rollerblader. Rollerblades are difficult to control and stop quickly (haven't mastered the sliding turn quick stop). They are much more sensitive to surface imperfections and slick surfaces than a bicycle. Finally, rollerblades are heavy and still require you to bring extra shoes, putting them on and taking them off takes about 5 minutes... All of this makes them impractical for commuting.

Inline skates on flat ground are technically "no external energy". And they can race a marathon in under an hour, so that's 26+ mph (42 kph)

The proposed device is predicted to allow almost double that speed. I think it’s pretty cool.

What? That’s faster than track cycling world records! The 200m flying start record is 9.1s which translates to 79km/h. The makers of this device are proposing to let humans run faster than a world record track cyclist!

I found strangely amazing your inability to realize it was a joke the moment you googled "Naruto run"

The top hit for "Naruto run" was some random anime video. It was not at all clear that it's a meme and the joke went way over my head.

Just as a heads up, not everybody watches anime.

Nike Vaporfly. I'm surprised it wasn't mentioned that 2 recording breaking marathon runs were by athletes wearing the Nike Vaporfly shoe. The shoe was ultimately banned due to the giving too much "bounce" (free energy) to the runners. https://www.reuters.com/article/us-athletics-shoe/nike-proto...

Well I'll be... that ugly design has a purpose
