This goes back to the OPs original post. You can have two pressure 'sources'. Pressure from heat and pressure from molecules. With pressure from heat you need to transfer the pressure as quickly as possible because your efficiency losses to the walls of the chamber are greater. In a wankle engine that expansion period is much shorter. I think this is the way you get greater efficiency with water injection in a piston engine, you convert a portion of that combustion temperature to gas.

I assume since it is noiseless it is using a fuel cell. As to your concern with pressure, I know that the Wankel is the preferred ICE for hydrogen. Not sure why but it is more efficient than a piston engine.

It was a gas!

Maybe they just haven't tried. My uncle was a dairy farmer and had interesting anecdotes as to why he thought cows were smarter than generally believed.

Most likely it is the nitrosoamines which are quite abundant in tobacco smoke.

If you read the original article, the simply state that they can document methlyation changes to DNA. For all we know, the body may be doing this methylation to help repair damage or neutralize toxins. The conclusion that "smoking damages DNA" is unfounded.

Microsoft is touting 30fps at 4k. Sure that is doable, but so what if the renderer is using the same number of polygons or turning off environmental effects. The true benefit they can guarantee is that things like menus and web browsing will be a lot clearer.

It would be a real public relations coup for someone like google to break in to the redneck crowd. Like it or not they make up a big portion of the economy.

Tire wear and brakes overheat.... gas is burned and the weight of the car changes. Some cars will just be running faster than others, so the programmers will want to take advantage of that to win. Also the cars would have competing algorithms and settings, so there would be much more variability than you think. And once the tech was sufficiently advanced they will be running with human drivers in something like the 24 hours of lemans.

It's clear that you don't understand the first thing about auto racing. I am not suggesting people will come out just for automated racing, it is simply a matter of adding a class to an existing series. And no matter what you think, racing would provide tons of useful data to automation developers.

There is no money in ANY auto racing....it's purely sponsor driven. And while the software would have to be modified for other scenarios, the number #1 concern would be to avoid other cars without causing an accident and racing would be great for that.

This is one of the reasons I think Tesla designing a self driving car is a bad idea. The leading software is going to be transferable to any other car maker... the I/O is going to be standard across automakers. If things eventually go the way they do in software industry the Tesla will end up with Bosch, Apple or perhaps Google autopilot in it. So what is the point of sinking all that money into Tesla autopilot and taking all the liability risks?

I've wondered why there is not an automated racing series.... most new performance technologies are vetted first on the racetrack. This would be a great way to develop bulletproof software.

There is an easy explanation to this.... what about a driver that does one ride a week? The transfer cost would be a huge percentage of the paycheck.. so why should Uber eat it?

It would be fine if the central bank, leading economists, politicians would acknowledge this. Deflation can be good if it is accepted and prepared for... But instead it is 'full steam ahead' and they are pulling out all the stops to avoid it, which will make the effects deeper and more profound when they happen.
