Pretty much what I said. It's not an electric rocket, it's a regular rocket with an electric turbo pump.

It’s not really a new type of rocket engine, it’s a new type of turbo pump for existing chemical rocket engines.

Probably because of recurring comments like these and the equally ignorant “rolling coal is stupid” when referring to tractor pulls.

This looks a lot like my first few attempts at landing on the Mün.

Tyler responded to another comment asking basically the same thing. The answer is "semi-autonomous". There is no one at the controls but it has a desktop-like user interface to command it to refuel. That's my understanding at least.

I can’t wait to hear more. I am seriously considering getting a 4C. Also, probably a poor decision but who cares, it will be my only mode of transportation for a while. Hopefully this summer I will have saved enough to make a comfortable down payment.

What about landing on a planet besides earth that has oceans? *mind blown*

Yeah, landing on the edge of craters sucks. Ive had several times of going “oh shit” and trying to stand my lander back up with the SAS.

This is the most logical thing I've read as to reasons why it didn't work. I suppose it comes down to fine tuning the software or maybe some hardware changes to help the system react faster. The only other thing besides that is being able to scrub more speed off earlier to line up with the target. The problem with…

How about a building/many buildings being powered by a “jet engine” aka gas turbine?

Excellent, now my dreams cloning Kevin Harvick can come to fruition.

Electric cars have been around almost as long as gasoline cars, turn of the 20th century. The biggest hurtle for electric cars is still energy density of the power source whether it’s batteries, fuel cell, or however you generate electricity. The real driver, or shall I say hold up, is cost. Even with huge incentives,…

Sounds like someone needs a bass hovercraft.

When you start comparing thrust producing engines to torque producing engines, the comparison is apples and oranges. Brake horsepower is an actual measurement of the torque on the output shaft while equivalent horsepower numbers quoted for a jet engine (or rocket engine if that's the case) are thermodynamic horsepower…

I talked to a guy who bass fished professionally and another thing is that a lot of these tournaments aren't restricted to the main body of water that you launch in. If you can gain water access to any tributary, it's fair game but you've gotta haul ass to get there.

Well played.

Yes but they can easily burden the healthcare system when they do.

This dude was fortunate to have been saved by modern crash safety equipment. Yet there are still people who refuse to wear seat belts. SMH.

I believe that there is a mandated seat strength requirement for rear end collisions. I'd have to look it up and find the relevant FMVSS document that specifies crash safety though so don't quote me on that.

It’s to test out the technology and ensure it can operate safely before it gets implemented. They are still in the preliminary stages of certification. It's exactly the same thing as getting an experimental certificate before an aircraft is certified. Shitloads of restrictions. They probably won't be delivering to…
