  1. An 18-year-old recently won $50,000 in scholarship funds for inventing a supercapacitor that could one day be used to fully charge a mobile device like a smartphone in just a few seconds. Eesha Khare and two other teens were among...

    Great job, Eesha, but I hope phones aren't the end of this technology. One of the biggest drawbacks to electric vehicles is the approx overnight charge time, if that can be brought down to a couple minutes (like the time it takes to fill a tank with gas) then a huge hurdle to EVs will have been cleared.

    Of course, your phone charger only draws like 10 watts of power from the wall, so drawing 100 times more to charge your phone in 20 seconds is no big deal. Your car already needs the full 100 amps to charge in 8 hours which means you wouldn't be able to draw more power to charge it faster. Hopefully that won't stop specialized stations from providing the power.

    Wow thats cool, I envy those smart kids.

    A flux capacitor, a galaxy navigator, and an AI that can lit a single bulb. If it all sounds to you like a familiar sci-fi flick, you are not alone in this...
  5. $50K is a lot of money to this kid. Should pay for a year of college. Whoever buys it off of him should stand to make millions. Hopefully he will too.
  6. 1745 the capacitor is invented. 2013 it's used to power LED.

  7. Thats fantastic! Now I am curious what their parents do for a living? Are they scientists with PhD as well or just your average Joe stocking cans at Walmart?

    Only to those inbred to the point they have been stripped of the genetic ability to shut their mouth.

    That likely doesn't matter though, as the only "prey" they're capable of sneaking up on are candy machines, which are plentiful and slow moving....;)

  10. This is so horrible. This is exactly why I don't allow my children to eat chicken tacos after midnight. If we don't come together as americans and fix this problem soon our children will pay for this!

    Yes, my thoughts exactly. And whatever you do, don't get them wet or expose them to bright light.

    You know something, I didn't even think about that cell phone capacitor's ability to let kids keep on talking. I can just imagine the bill once my son and daughter get their cell phones...I am all for the government suppressing this invention!
  13. Most cell phone batteries are in the 1-2Ah range, so to charge one up in 20-30 seconds would require at least 100A or more of charging current. That much current will require some fat wires, which I suspect the average consumer will not like. How did the intel people miss this?

    This Supercapacitor could really revolutionize the cell phone/Apple products industry, I really want to see what might become of this technology in about 5-10 years. A few things like this and Google Glass have really surprised me and I am quite excited for things to come out of the beta stage.

    These teens are pretty impressive. I just dont feel like these inventions are as significant as the cheap cancer detecting paper (I think that is what it was) that another teen created last year.

    Just don't fall for the bulls*** from the kids about you'll "know where we are at all times". Just have them micro-chipped like you would a pet, and make them get jobs after school to pay for their own phones. Then you really will know where they are at all times...;)

    Yes, and passing that much electricity through anything creates heats. Oh well, since we already have exploding laptops due to batteries, I think it's high time this level of "progress" found its way to the cell phone arena.

    Although I think you could bypass the heat issue by charging your phone submersed in a tank of liquid nitrogen. And just think, it will stick to your ear when you first pull it out. Verily, a new milestone in, "hands free operation".

    Yes, this is one area where patents have potential for failure.
    Great at the risk of allowing teens the chance to talk longer, your going to minimize your own chance to talk longer. What ever happened to talking the kids toy away in the event of forcing them to cooperate? Would you allow teens to continue their disagreeable habits, to minimize confrontation?

    The issue isn't charge speed, its charge life.
    Give me a battery that fits in my Droid 4 and lasts 20 days and I'll be impressed :p.

    I hear you.

    We keep embracing new tech that greatly decreases battery life as we strive to minimize power consumption. If we would stop introducing new ways to drain power, perhaps we could increase battery life. But then where would that get us? They would still proportion the battery size with how long it last. Longer battery life would equate to smaller batteries, so your device stays charged the same length of time.

    Batteries used to be half the size of the phone. How long would battery life be, if that was still the case with the average cellphone?

    "Intel said the invention also has potential applications for car batteries but it?s the mobile side that could have the most immediate potential."

    Intel... talking about car batteries? ....and the fact that's all they could think of?!?!

    The good news is that the son and daughter are eight and six, respectively. The bad news is they're not afraid to get smacked upside the head when they get out of line. I can only imagine them when they're fifteen and thirteen. Maybe passive aggression will avoid active aggression.

    You know technology isn't bad. It can be used in a good way. But it always ends up being used bad in some way or another. And it's unbelievable for me to hear people say: " it's the technology's fault for letting this happen". Oh please! It's the one wielding it or the one that has the power to monitor it that has the responsibility to use it in a good way. If your kid has problems with controlling certain habits, then help them overcome it. That's why you are the parent. And please people we are striving to be IT-pro's here. So let's be wise and wait and see what this has to offer instead of talking it down

  23. Up until petrol lasts why would you think oil company's and government would allow that ?

    cliffordcooley TechSpot Paladin Posts: 5,062   +1,179

    Because I would like to think they have no choice but to offer people what they want. But in reality your insinuation is likely correct.

    I hope this kid will invent a new engine that is still powered by oil (gasoline or diesel) but at the efficiency rate of 1 mL per 100 kilometers.
