I've talked to folks who insist that flush pressure is directly correlated to water pressure. For some toilets this is true, but generally toilets have a reservoir which is used to flush the toilet (you can actually flush the toilet completely disconnected from the water source if you fill the tank).
EDIT: US households. I don't know about toilet arrangements in other countries.
Something like the Oculus (VR) or Hololens (AR) IMHO.
Problem with the "future mother of all demos" is that it seems the viewers need new hardware to experience it. How do you do an "AR" demo that's not distinguishable from movie FX (i.e. a fake example).
This was my first thought too, however when I think about it more. Oculus/hololens are really the same applications with a different perspective. It's a damn cool demo to be sure, but not life changing in the same perspective.
The great demo showed a future with a brand new category with brand new applications. AI seems more likely to me AI is the only tech I know about that could produce a demo on the same level.
I've done that, and you're right, it's loads of fun. A few hours of instruction, however, will not make you competent at handling a car at its limits. One thing I did learn from those classes is how poor a driver I (and nearly everyone else) am.
When gaming my modestly configured desktop (i5, GTX650 ti, ssd/hdd combo w/good air cooling and good case cooling) pulls 250-300 "at the wall" according to my kill-a-watt. I would imagine that as you go up the "gaming" chain (multiple GPUs, water cooling, etc) you could find yourself at the upper bound of that range.
Clutchless manual in the Smart. I looked at getting one a few years back, but I couldn't justify $15k for a two-seater with almost no breathing room and storage space versus $12k for a Nissan Versa with nearly the same MPG and a huge back seat area/storage area. I simply don't understand how they can justify $15k for what boils down to $9k worth of car. It's all hype.
I think the attraction with the Smart series is two things. One, it's meant as a city car, so it makes sense for someone in a fully urban area who needs something easy to park. Two, it is pretty much a fashion statement: "Look at my tiny Kei car!"
Now, the second thing is purely subjective and if you want a car based on popularity or "being different", more power to you. Here in the deep south, we have guys and gals who buy the biggest, baddest pickup truck they can...and never haul a thing in the bed for the life of the truck. Pure status symbol. I can imagine a similar mindset among the local twentysomethings wanting to stand out from the crowd by driving an equally impractical car.
This is my idea of a truly smart car, and with a sensible price:
