    Scientists Find Fundamental Maximum Limit for Processor Speeds

    By Adrian Covert Posted on 10.23.2009 21 Comments

    Silicon wafers. Quantum computing. Light-based processors. Any way you slice it, scientists say that processor speeds will absolutely max out at a certain point, regardless of how hardware or software are implemented. Lev Levitin and Tommaso Toffoli, two researchers at Boston University, devised an equation which sets a fundamental limit for quantum computing speeds. According to their studies, a perfect quantum computer can generate 10 quadrillion more operations per second than fastest current processors. They estimate that the maximum speed will be reached in 75 years.

    One thing that is always forgotten is the fact that Man ingenuity is infinite. We may not use silicon but what about dilithium crystals. What about positronic networks, or better yet anti-matter. Last but not least what about using things that all ready moving faster than the speed of light like tachyons.

    Al Gore and company have helped us to see that our planet is in peril. Lend a hand, make a toast, and help illuminate ways for saving Earth -- all at the same time! It's easy to do your part: recycle, refill, and recharge.

    Hey Kase9, and everybody else that tried to do it this is what you do. First the solar panel the side that has the bars on it (not the shiny side) is the the correct side. Secondly on the solar film you will see something that looks like this "I- I- I-" the direction of the dashes is the negitive and the bar is the positive. Connect the negative side of the solar film to ground. Next all the sides that go to ground connect them all together and run them to the negative side of the battery. Since ground current wants zero whats less than zero the negative side of the battery. It's not a bad idea to have 2 regular batteries and some extra wire around. If you connect the batteries -+-+ and connect both ends to the L.E.D. poles (anode and cathode) you will quickly find out which is which. This way you can find out the polarity on the LED otherwise it won't light if it is connected wrong. I used this same tool to connect the positive and negative side to the batteries this should allow you to charge the batteries temporary so you can test the circuit. One last point the diode should be connected to the positive side of the solar film, but with the negative side attached to film and the positive side attached to the wire. This prevents negative current to flow the opposite direction draining the battery. I will post pictures soon, I really hope this helps because the directions were about as clear as a really really foggy day.
