10 Tech Concepts You Should Know for 2007 195

From PRAM to BAN and SmartPills to data clouds, it's a pretty nice summary of upcoming and in-the-works trends across the board (with a podcast embedded). Though these aren't technologies they expect to be in everyone's homes next year, they're sure this tech will be in the headlines. How do their predictions from a year ago stack up now?" From the article: "Printed Solar Panels - Tomorrow's solar panels may not need to be produced in high-vacuum conditions in billion-dollar fabrication facilities. If California-based Nanosolar has its way, plants will use a nanostructured "ink" to form semiconductors, which would be printed on flexible sheets. Nanosolar is currently building a plant that will print 430 megawatts' worth of solar cells annually--more than triple the current solar output of the entire country."

    Radar sensors and computer-controlled braking will keep drivers safer than ever, but what about pedestrians? In case your adaptive cruise control fails to spot someone darting into the road, TRW Automotive is introducing the PPS system: if you smack a pedestrian, the hood is automatically raised to cushion his landing on the engine block. The system is already being tested, part of a drive to meet new European and Japanese regulations on pedestrian safety which are being phased in, starting with 2006 models."

    Even if they make theoretically impossible 100% efficient solar panel. That's not enough for me to buy a solar panel.

    However, if they can make a 5% efficient solar panel. I will buy it.

    Why? It all comes down to cost. Solar power is too expensive for me. It takes over 5 years for a solar panel to pay for itself. Also, a solar panel only lasts (the efficiency declines over time) about 20 years. The capital cost is too high.

    So companies should focus on reducing the per watt cost of solar panels. Not on improving the efficiency. If you can make solar panels for $5 per 100 watt panel .. you can bet I'll be off grid. I don't care about efficiency, I only care about cost.

    A 100% efficiency solar panel can take up 1 m^2 and generate a kilowatt, a 10% efficiency solar panel would need 10 m^2 to match that up .. but if you think about it .. the sides of the square are only 3 meters wide versus the 1 meter wide sides of the 100% efficiency panels. That's not a huge land area to sacrifice.
    • A five year payback is great, roughly the equivalent of 15% interest. That's far better than stocks, with far less risk. Ignoring risks and commissions, the stock market can be expected to have a 8-10 "payback time".

      So in 20 years the solar panel just stops working?

      I think not. actually it's an asymptotic curve which levels out over time. Yes their peak is at teh begining, but they still produce Usable power for a long time.

      From Wiki ". (Normally, photovoltaic modules have 25 years' warranty, but they should be fully functional even after 30-40 years.)"

      http://en.wikipedia.org/wiki/Photovoltaics [wikipedia.org]

      Also, your economics are slightly skewed
      your not paying for 100W of e-. Your paying for a system to manufacture a peak of 100W of e- during daylight hours (avg probably 50W (just guessing?))

      If it was $5 for 100W panel, e- would be close to free anyway because everyone would produce their own.

      Secondly not many man made conversions happen at 100% efficiency.

      I am not a huge alternative energy freek, but economics dictate that solar panels are allready a smart choice for home use. Admittedly, if demand for them suddenly increased, that would not be so. But assuming e- prices continue to go up, (they will, you can bet on it in the long term for at least another 20-40 years) Then you have an even more economicaly strong position. Now, it's probably not going to net you the hugest gains, but it pays for itself, and then more. It's a solid return, that lasts a long time, and is scalable, upgradeable, and virtually maintenance free.

      P.S. talking about grid tied, inverted system here. None of that silly battery stuff.
    • Uh... Printable solar panels, by negating the need for extensive/expensive fabrications processes will do both, make them more efficient and less expensive. Isnt that the whole point?

        Heck, it's hard to argue against buying solar panels now. If they pay for themselves in 5 years, as has been suggested upthread, and they have a functional lifespan of > 25 years, you could buy >25 years' worth of electricity for the price of 5 years' electricity. The only 'risks', really are: a) what if the price of electricity goes down? and b) what if the price of solar panels (cost:watt) goes down?

        If solar panels paid for themselves in 6 months, I'd cover my whole roof with them, sell my cars and buy cars that can run on electricity, convert my gas furnace and hot water heater to run on electricity... and I'd give my oil, coal, and gas-burning brethren unending hell until they did the same.

        Who paid $10k for an electrian to wire you to the grid?!?

        The power company runs the power to your house for free in every state I have lived in. They will even upgrade the service from 100 amps to 200 amps for free. The only "tie in to the grid" is the connection from the meter to the mains, which are less than a meter away from each other, as required by code.

        This is a $200 job, not a $10,000 job. Everything else you are paying for, from the mains to the socket, has to be done regardless of where the power comes from. AND you can wire a brand new 2400 sq ft house for less than half of what you are claiming, sockets and switches included.

        Now, to hook your DC powered solar panels up to use in your home, you will need to either wire new DC circuits to everything or use an inverter system. To connect YOUR power to the grid to sell back/use off time, and sync the phasing, etc. you are going to spend several thousand for autoswithing, inversion, etc. It's worthwhile, but it isn't cheap to connect your OWN power source to the grid.

        Your numbers are simply out of whack and (with all due respect) not based on real world scenarios.

This blows away the PRAM mentioned in this article. The lesson: IBM's unreleased product will always be better than your unreleased product!
    • While the PRAM developed by a joint project of IBM, Macronix and Qimonda is very impressive, it's still a long, long way from production because no commercial fab can manufacture it on a large scale. But Samsung's PRAM is far closer to production, and by the fall of 2008 don't be surprised if Apple ships a video iPod that uses 80 to 100 GB of PRAM.
      • Who cares if Samsung's PRAM is in production - it's obsolete! I'll take nonexistent superior technology over available obsolete technology any day of the week. It's so much cheaper that way...
  • New? Anyone who's ever done anything with old Macs knows this is the Preferences RAM [wikipedia.org], and when the clock starts acting funny, it's time to replace the PRAM battery.
  • I've known about PRAM for many years now. I was hoping by 2007 I wouldn't have to know about it, as it would be made obsolete - and I would no longer have to "zap the PRAM" when things start acting funky. Sigh.

    I guess when #3 comes about, we will be living in the "VoN Age"?

    My Grandfather [adelaide.edu.au] was an expert on concrete, especially pre-stressed concrete. One of his party tricks was to show off a piece of thin, flat concrete, slightly larger than a standard ruler, then bend it in an arc.

    He'd created this by stretching a thin wire with weights along a form, then pouring the concrete. Once the concrete was set, he removed the weights, which caused the wire to shrink, compressing the concrete and rendering it much more flexible.

    Admittedly, they're actually talking about a different technology in the article, but they make it sound like no-one's ever made bendable concrete before.

      You're right, this isn't the same tech at all. What your grandfather demonstrated was an extreme example (ie very thin) of a well-established structural technology - pre-stressed steel-reinforced concrete. Putting the steel members of a beam under strain before pouring in the magic-mix is very, very widely used in the construction industry.

      The reason this allowed the beam your grandfather manufactured to be so flexible is that it was so thin - basically a steel member with a coating of concrete (probably w
