The Best Of What's New 2007 66

Posted by Zonk
from the can't-believe-the-year's-almost-over dept.
BlaineZilla pointed us to one of the earliest annual 'best of' roundups: Popular Science's Best of What's New awards. The winner this year is a nanosolar powersheet that may someday change the way we think about renewable energy. Other winners include the corot satellite, a project aimed at searching out habitable planets in other solar systems, and the world's most advanced bionic hand.

        I wouldn't say vaporware because NanoSolar does have a $9 million dollar contract with the DOE and has a working prototype production of said solar film that actually works. History Chanel had a small clip about their production line (not the History Channel Clip but shows the same machine http://www.youtube.com/watch?v=4riNlqZHCTQ [youtube.com] ) so its out of the R&D theory stage and will have to go into mass production phase.

        Its no longer a question of "if?", but rather "when?"

          According to a posting from NanoSolar on their Yahoo Groups page, their entire 2008 production run is already spoken for. They suggest general availability won't come until 2009.

        Nanosolar is specifically touting their cost-effectiveness. Thus the price to actually buy the product is extremely relevant. Anyone can claim that their product will be a better deal, but until it ships, such claims are hot air.

        • Somewhere there's a quote of approximately 30 cents USD per watt.

          I'm not sure if this is solely the manufacutring cost, or what they'll be selling the panels for in bulk.

          And my point was that nanoSolar probably won't produce any products that you'll be able to go out any buy yourself. They're not that kind of company, and their product doesn't really lend itself to that sort of distribution channel.

          They'll instead cater to other manufacturers to allow them to package the panels into their own products. 3M

    Although I was pretty skeptical about the buzzword-laden NanoSolar, after reading TFA, I've gotta say that their technology is absolutely incredible, and unlike most of PopSci's outlandish predictions looks like it very well break into the mainstream. Although it's not going to singlehandedly solve the energy crisis, if they can ramp up production quickly enough (and maybe cut costs even further), we'll soon begin to see a more widespread adoption of solar power.

    As long as the cells are cheap enough, the applications for it are impressively extensive. The cells themselves are incredibly light and thin, and looks like it can be applied to just about any flat surface. It won't power your car, but it might make your hybrid/electric go a few extra miles before the next charge. Flat-roofed buildings can cover themselves in the stuff, and greatly reduce their energy usage. (Alternatively, a facility such as a warehouse could possibly even break even on its energy usage by keeping itself lit during the day with skylights, and selling the energy from the roof back to the grid. During the night, power for artificial light is taken from the grid)

    You might even be able to apply the film directly to the body of a car or to roofing materials, given that the underlying backing doesn't need to be anything terribly special.

    The fact that they're doing the majority of their research and production in the US and Germany also suggest that the manufacturing process will be relatively clean, and that their workers will be paid decent wages.

            How bad is it? The best Current Production Silicon Panels push around 30%, giving around 250-300Watts/m^2 (depending on latitude, season, and air quality, it can be even less). Of course, they're also relatively heavy, and quite expensive usually around $1000-$2000/m^2 (driven by low production capacities and very high demand). If these things can do at least 15-20% with flexible panels, They'd easily be able to get the prices I listed above just on the basis of being able to completely cover buildings
        • I'm pretty skeptical as well, but they seem to have produced working prototypes, and have a good idea of how they're going to be able to produce them efficiently in massive quantities, and have solid investor support. It's definitely not snake oil. It'll be some time before we know if it catches on or not, but despite the cheesy name, they do seem to have their act together.
      • Well, if nanoSolar doesn't do it, someone else will.

        Thin-film deposition is a very promising area of research for a variety of applications, allowing for very advanced surfaces to be "printed" onto ordinary materials. The fact that they've proven that photovoltaics can be produced in such a manner is extremely significant.

        When it comes to cars though, it could be said that "Car of the Year 2007" means "Best Car of Model Year 2007", where the Model Year 2007 cars rolled out some time around August or September of 2006. The 2008 cars rolled out months ago, and pre-production models have been available for review since March or April, so it is hardly surprising that they have already been reviewed, compared, and ranked.

        That said, all a list like this needs to do is say "Best of 2007" and in small print, add "(so far)". Any cons

    As of the end of 2006, the total worldwide installed PV capacity was 5.7 gigawatt at peak. Norway, a country with a population bellow 5 million, consumes more electricity than that. Single nuclear power stations can produce more electricity. Seriously, solar will NOT solve the energy crisis in any near future. Even with an exponential growth of solar power, doubling installed capacity every 5 years, it would still be more than 50 years until you get to the same order of magnitude as PRESSENT energy consumption, and this is at peak power.

    Proponents of solar power usually talk about how its efficiency is about to jump several times in the near future, but even if you improved the efficicency tenfold ( which would put you above 100% efficiency) you would still not even be within 1% of pressent energy consumption. Seriously, maybe in a century, but photovoltaics just isn't going to replace Oil before it runs out.

    To get a slight idea about what will be required to phase out fossil fuels, have a look at this diagram: http://en.wikipedia.org/wiki/Image:World_energy_usage_width_chart.svg [wikipedia.org]

    Solar and Wind just ins't going to solve that issue alone. Neither is nuclear, biofuels, or clean coal. It should be damn obvious from that diagram alone that we are going to need every piece of clean energy we can get our hands on. Expanding the use of nuclear and biomass 5 times, would take care of the first 50%. Carbon capture and storage with coal sticks you up at 75%, and expanding wind power 100 times can provide the remainder. All of this assumes strict energy conservation measures to keep the overall energy use at pressent levels. Of course, with the developing world industrialising this appears unlikely, so you will need some more energy, but ff we go for the optimistic goal of preventing overall energy consumption from increasing by more than 50%, then it is doable, PROVIDED we use all energy sources we can get. To reject carbon capture and storage, nuclear or other energy sources, based on some delusional pipe-dream of solar power coming to the rescue is however just wishful thinking.

If adding more generating capacity costs less per watt than ANY other form of power, including burning coal, then solar wins by default. All NEW power plants would be solar.

      Oddly enough, efficiency is exactly the WRONG measurement here. Cost per watt is the primary factor. If we could produce a 100% efficient solar cell for $10/watt, it STILL wouldn't sell except for satellite applications.

      However, a 15% efficient cell that's easy to install and costs $0.30 per watt (as the nanosolar is supposed to) will sell BIG. Given those figures, even with the rather cheap power I get from the grid, I could see a 2-4 year ROI installing that on my roof. OTOH, the $10/watt 100% efficient
