News and discussions on new technology

  1. What's new in this club
  2. Variable compression engine

    Somehow I can't see this engine running on bearing shells. This is definitely a roller bearing repository...
  3. Variable compression engine

    I don’t think the longevity will be much different from the current piston/rod/crank engines as it will all be running on the same type of shells, albeit more of them. The real killer will be lack of oil changes but you could apply that to any engine.
  4. Variable compression engine

    I was going to mention the reliability issues, but it was way past my bedtime when I last commented on this. I do agree though- only time will tell how long these beauties will last under real-world driving conditions.
  5. Variable compression engine

    Wonderful piece of engineering. However a lot of moving parts. But it would be interesting to see how it fairs with high mileage. Also a rebuild has to be expensive in materials and labour. Time will tell gentlemen.
  6. Variable compression engine

    It should be an interesting job but somehow I don't think some, or even all of the moving parts will be available to the repair trade anytime soon. Besides, I don't think there are engineering shops anywhere in the world that are equipped to do the machining- there is some weird stuff in this engine that I think would require balancing to a degree we are not used to seeing even in high tech racing engines.
  7. Variable compression engine

    I would imagine so. Over 100 prototypes before they perfected it? I would hazard a guess that a few of the failed ones were the engines shaking so hard the heads came loose. Even so, everything working in harmony like that just gives me a nice satisfied feeling. I'd love to do a tear down and rebuild on one.
  8. Variable compression engine

    Balancing this thing must have been a bitch...
  9. This looks interesting. Why did nobody think of it before?
  10. Nissan brain to vehicle interface

    This might seem like a workable plan, but some questions that come to mind are these- 1.) To what extent will the system eventually be able to compensate for a driver's lack of practical driving experience? 2.) How will the system compensate for the stupid, and aggressive attitude some drivers assume the moment they get behind a steering wheel? 3.) Will this system eventually be able to detect stupid and aggressive behavior in a driver and then be able to prevent that driver from acting on his stupid and aggressive impulses?
  11. Hydrogen is very difficult to store. Hydrogen molecules are so small that they escape through the material used for "normal" fuel tanks, and while effective storage tanks do exist for use in vehicles, they are very heavy and take up a lot of space in a normal vehicle. The alternative is to use fuel cells in a vehicle to generate hydrogen on demand, but on this scale, the technology is expensive in terms of the energy required to make a given volume of hydrogen gas. For the moment, electric cars are cheaper than hydrogen-powered cars to produce, and is likely to remain cheaper until the issues of bulk storage and distribution of hydrogen are resolved.
  12. No full details yet but it looks like Hyundai are set to release a hydrogen powered SUV Anyone got any thoughts as to why hydrogen hasn’t really taken off as a fuel yet?
  13. Nissan are working on a new system where the car will read your brainwaves and react 0.2-0.5 seconds quicker than your body can
  14. Possible upcoming electric Lamborghini?
  15. EV for the deceased

    Perhaps they are trying to tell us something...
  16. Nissan have now rebuilt the Leaf as a hearse.
  17. Rothschild conspiracy

    This may be relevant. An old 1988 The Economist cover page.
  18. CGON hydrogen additive

    Snake oil- even without reading the article you reference. Even with the addition of some hydrogen to the air/fuel mix there is no way to reduce the emissions caused by the hydrocarbons in the petroleum fuel component of the mix by 80%. Moreover, without a re-flash of the ECU to re-calibrate oxygen sensors/fuel/air ratio sensors, exhaust gas temp sensors, and Nox sensors (among others) the ECU will just enrich the fuel mixture when it reads a fuel mixture that is 80% leaner than it should be. So, no 33% increase in gas mileage, either.
  19. I stumbled across a company in the U.K. called cgon who sell a device that adds hydrogen to the fuel-air mix which claims to increase fuel efficiency by up to 25%. They also claim that it reduces emissions by up to 80%. One customer testimony on the website claims their gas mileage was increased by 33%. So, Real or snake oil? I call snake oil because it's been around for 2 years and the manufacturers haven't adopted the technology then it can't be up to much
  20. Rothschild conspiracy ICV future indeed seems very dodgy
  21. I won't get too much into my thoughts on the Rothschilds because most of it is rather unpleasant but I came across this on YouTube and thought it was worth sharing. Something big is going to happen which will affect all of us and we will have no control over it. Anyone care to guess what it is? They sold a lot of USD stock a few days ago so something is definitely afoot that we dont know about.
  22. Silent Horse's

    Aston Martin did this a long time ago but slightly different.
  23. Silent Horse's

    Finally a car company picked up some technology from end user. This aftermarket exhaust with customizable sound has been existing since few years now and its good to see Ford perfecting it and adopting it in it's much needed car
  24. Silent Horse's

    The new 2018 Mustang GT will be available with an optional active exhaust system, which can be quiet when it needs to be but open up and let the V-8 growl when you want it to. Add a little bit of programming, and Quiet Start was born. According to Ford, Quiet Start, also known as "Good Neighbor Mode," is essentially a timer you can program to automatically put the active exhaust into its quietest mode during certain hours, even if you parked it in wide-open track mode. Be a good neighbor with the 2018 Ford Mustang, with Quiet Exhaust mode and Quiet Start* features that are a part of the available new active valve performance exhaust system. Quiet Start lets drivers schedule the time of day when either the Mustang GT’s V8 engine roars, or when it stays quiet for neighbors.
  25. Zinc-Air batteries

    With the regards to overnight storage of electricity generated from solar, Tesla are currently building the worlds largest lithium ion battery, 130 MWh iirc, for a wind farm in Australia. Wether this will be used for long term storage or like a giant capacitor to balance things out, I'm not sure, but it does show that we are moving in the right direction. Obviously though, it will not be possible to build thousands of giant lithium ion batteries due to the limited supply of lithium and the impact on the environment. Maybe Zinc-air will become a viable solution? There is also the option of building huge salt water batteries. Salt water is something we're not short of.
  26. Zinc-Air batteries

    What you say is true, but the problem with solar power is that it only works when the sun shines, and presumably, the millions of electric cars will all, or mostly, be recharged at night. So far, nobody has worked out a way to store large amounts of solar-generated power for any period of time, which means that when the sun goes down, solar power effectively disappears for everyone but those who have small-scale domestic systems. However, as you say, fueling the power stations is still the overriding factor/problem that prevents large scale electric car production, and at this point, it seems that nuclear power is the only viable option, even though it is inherently dangerous. Water and wind can never generate enough power, but what little of it there is, is always welcome. Nonetheless, some years ago it emerged that the Russians had been planning setting up huge mirrors in space to reflect sunlight into agricultural areas at night to extend the growing season in far-northern latitudes, but several international treaties put a stop to that. If that could be revived and made to work, we could maybe have solar power at night too, even though the astronomer in me will fight this idea tooth and nail, since all the stars will effectively disappear from the night sky.
