What is the future of the internal combustion engine?

Some people believe this engine will be phased out eventually. Others think it'll only get better and better as the years roll on. I think there's an an upper boundary to how much better it can become, and therefore there'll come a day when someone will build a museum for them. What do you think?

With electric vehicles on the horizon and battery technology improving each year, a bright future for these engines is becoming harder and harder to see.

  • Aug 15 2013: Instead of batteries, I would like to see a capacitor designed to run a electric car. You could charge the car in the fraction of the time it would take a battery. The charge would be limited mainly by the conductors and charging station. If I take a trip of 500 miles, I do not want to have to stop halfway for hours to recharge. Instead with a capacitor you could recharge in a fraction of a hour. Perhaps a capacitor could be made using ceramics.
    • Aug 15 2013: You mean... this?
      "NPL have overcome this issue, as part of a Technology Strategy Board funded project. The outcome is a capacitor, called HITECA, that can operate close to normal efficiency at over 200oC, significantly higher than any other capacitor on the market. It also offers a high energy density -- the measure of how much energy it can store."

      "The most promising materials were optimised to achieve the desired properties. The resulting capacitor is created from a ceramic, based on doped-BiFeO3 compound."

      • Aug 23 2013: density is one thing, discharge rate is another. today's capacitor is no where near discharge rate of a standard alkaline batteries, hence the alkaline batteries stay for a little longer :)

        August 2013:
        "Monash University researchers have developed a completely new strategy to engineer graphene-based supercapacitors (SC), making them viable for widespread use in renewable energy storage, portable electronics and electric vehicles."
        • Aug 26 2013: Ahhh! You found it!

          I was trying to find that article in response to Eko Fadhillah's post, but it wasn't turning up in the search engine provided by the source I first stumbled upon it on. It's amazing where technology is going, and graphene is seemingly popping up with new applications all the time.

          thanks for posting that!
