  1. Re:Solar is taking over regardless on New Material for More Efficient Solar Cells · · Score: 1

    You are quite right to point out that the grid can have big advantages.

    When writing, I especially had Nepal, where "the diverse and rugged topography of the country means that full grid connection of each and every household of each and every villages is practically impossible."

    Once a country goes decentralized, I don't think the economics justify adding a grid, because it is so expensive. It might be more likely to have hydrogen be used as a storage and transport medium. In any case, grids have lots of transmission losses, are capital intensive and can't be built up gradually like increased solar capacity.

    That said, it does have huge advantages, so it will be interesting to see where the grid will stop- maybe somewhere in suburbia, where the density justifies the cost, or to large rural customers? Or perhaps we'll have mini-grids at a village or neighbourhood scale?

    And on that same page, they do mention that PV prices can go as low as "$3.58 Watt: thin film and $3.16 Watt: crystalline." $5.85 is an average, which includes PVs that are designed for different systems. In my case, I only care about cost per watt as I will have a sufficient surface, others have to worry about squeezing the most energy out of a limited space. Different needs, different models and different prices.

    The most promising route will probably be solar rooftops, where solar cells are integrated with construction materials. For new construction or re-roofing, this makes a lot of sense because you don't have to pay much more for installation. With net metering, you also wouldn't need the expensive batteries. Of course, that assumes you're on the grid; if not, connection charges can be more than going the cost of going solar, including battery array.

    Solar is still expensive for now, and this has led most people that consider it to use every trick in the book to lower their energy consumption. Better lighting, appliances, windows, insulation... if it cost less money to conserve than generate, it only makes sense to spend money on efficiency. You probably do not need 564kWh/month- you should be able to reduce that by at least a third, with a payback in under 2 years.

    There are other applications too where cost alone is not a huge issue. If reliability is important, being able to have your own power supply, batteries, and a net metering arrangement with the grid could be a cheaper solution than most UPS, and give you far more autonomy.

    While you may not see it as rosey, it's hard to argue with the fact that sales are still growing, year over year. And I can't think of anything that could stop that in the next 20 years: it's all but inevitable.

  4. Solar is taking over regardless on New Material for More Efficient Solar Cells · · Score: 5, Interesting
    Even without this advance, solar is poised for even more gains.

    Solar sales are up 30-40% every year, and have been growing at such a steady pace for a long time.

    The cost of electricity from solar cells remains higher than from wind or coal-fired power plants for grid-connected customers, but it is falling fast due to economies of scale as rising demand drives industry expansion. Solar cells currently cost around $3.50 per watt for crystalline cells, and $2 per watt for thin-film wafers, which are less efficient but can be integrated into building materials. Industry analysts note that between 1976 and 2000, each doubling of cumulative production resulted in a price drop of 20 percent. Some maintain that prices may fall even more dramatically in the future.(link)


    Naturally, this is a positive feedback loop. Lower prices mean it's affordable for more niches, which means more people buy, which in turn scales larger. At this point, it's pretty much unstoppable. It is useful in too many niches, especially where customers aren't connected to a power grid.

    There are now many countries that have more cell-phones than landline phones. It's likely that in 10 years, some countries will have more customers getting electricity from solar than from a central grid. Naysayers will say it's not ready... but then again, 15 years ago cell phones weren't either. What matters is not the absolute numbers, but the growth rate of the industry and the evolution of the technology.

    Of course, as the market matures, more people are doing R&D to find cheaper ways to build PV systems, which is only going to accelerate this momentum.

    Everyone is comparing this to CueCat without saying why this won't work.

    The semacode website actually provides some intriguing uses for this technology. Since it is an open standard, we could think up other uses, but there are three that they mention that make sense to me:
    • transit info - nextBus
    • A web service to call a taxicab to your present location
    • ticket sales from posters (e.g. concerts)
    Cellphone prices are falling, and many people no longer even have a landline, so there could be a large market for this.

    Also, these uses don't cost much if anything. It probably will have a few niches. Can anyone else think of good applications?

    I have to point this out- it is also cultural arrogance to say your country was the most powerful "in every way". Spiritually, that is highly dubious, even if your prez finishes every major speech with a God bless.

    Although you fear a permanent decline in living standards, you haven't really seen an increase in the past 30 or so years. GDP had been going up, but real standards have eroded.

    A lot of your busy-ness increases GDP without creating actual value. Your system allows some to pollute (destroying value for others) while keeping benefits for themselves. Whether subsidizing mining, clear-cutting, burning fossil fuels... all are subsidized. Meanwhile, hiring people is taxed.

    You could be spending money on schools and healthcare, but instead you spend it looking for inexistent weapons.

    IOW, you have extraordinary wealth, you're just squandering it. It's not good for you or the rest of the world for the US to be reduced to nuke-wielding third world status. The US will no longer be a hegemon, but whether it has a decent standard of living is entirely up to you folks- all you need to do is stop wasting your resources.

  21. Re:Until... on Smart Breeding to Beat Biotechnology? · · Score: 2, Interesting

    Not from me it won't. I was active trying to get people to pay attention to the threat of GM foods more than 5 years ago, but whole-heartedly support this technology, and have for years (this is rather old news).

    Knowing many people in the "foodie" movement, and having heard organic famers describe their breeding programs, you'll find that most anti-GM activists will also support faster breeding, especially when it allows us to develop strains that are appropriate for local conditions and suitable for low-input, organic agriculture.

    The anti-GM movement is not anti-science or anti-progress. It emerged out of serious concerns with corporate control of our food supply and the poor quality of the gene-splicing "science" used.

    A big problem was found by Percy Schmeiser. He is one fine example of what happens when you get caught in Monsanto's lawyers cross-hairs. His crime? Monsanto's IP was in his field. No matter that they tresspassed to establish this, or that he didn't plant them, didn't want it, and viewed it as contamination of his crop... he lost his farm over this.

    But the problem that made me cry foul was far more frightening than a Microsoft of agriculture wanting to control most of our food supply's IP, scary as that is. It's that you can't "undo". When you put a fish gene in a tomato, you can't take the fish gene back. If pollen escapes - if the plant is crossed with others in the field - you can't selectively remove that genetic material.

    We could find a horrible allergy is introduced, a fatal toxin to some keystone critter, or a loss in yields. But once the open-pollinated strains are contaminated, how do you remove them? Go with all the commercially controlled hybrid varieties? hmm....

    Contrast this to the approach described in the article. We know these genes to be quite safe, as people have been eating and growing them for a very long time. We're just accelerating breeding. It may not be 100% safe, but it's as safe as anything can be. AND we don't have to worry about corporate control of a basic resource.

    When the topic of GM has come up on /. before, I have been surprised how easily, and I would say uncritically, people embrace the technology. Monsanto has the same ethics as Microsoft. They promise to end world hunger when all that matters is the bottom line.

    When it tries to use proprietary chemicals to allow seeds to germinate, we should be appalled - the same way we are appalled at DRM. When they patent genes that were bred through generations of farmers work, it should be seen as Sun trying to hijack GPL code.

    Anyhow, sorry for such a long post- the basic point being that no, most of us won't flip out and try to stop it if you call it gene-laundering :)
