    Not even then. This whole system is ran by whatever fuels the power plant (hint: that's gonna be fossil fuel based if you have these kind of emmisions.)

    You're basically just spending a lot of time and energy on turning exhaust gasses into fertilizer. If you already know about peak oil, this offers nothing more than biodiesel or solar. In fact, you might as well just grow biodiesel corn for the busses or run solar for the electric power grid.

    And there's no silly messing around with hybrids to get regenerative braking.

    Well, regenerative braking is just a way to tweak a little more energy efficiency out of any system. It also seems that it could be almost trivial to tack this onto electric cars: Any motor is a generator. Rather than the battery pushing electrons to spin the motor which spins the tires, the tires spinning pushes on electrons which goes to recharging the batteries just a little. I don't think I'm violating any major laws of physics with this. Would just take a little work telling the system when to act as a motor and when to act as a generator. Perhaps charging capacitors would work out better than batteries for regenerative braking.

    First off, diatoms are a type of algae. I believe that they are alot slower growing and have more specific environmental needs than other algae, in particular green algaes. One of the reasons that they would be so slow growing is the frustule (glass shell) that you mentioned. Making the frustule is very energy intensive, and causes a somwhat slower reproduction rate. Not to mention that as diatomaceous earth is basically powdered glass, it is quite abrasive and would lead to much higer maintenance costs.

    My guess is that this method is used on land because that's where you find the power plant exhaust that you feed into the system. The whole point of this is that they are taking harmful waste products (CO2 and Nitrous compounds in smokestacks which purportedly lead to global warming and acid rain) and breaking them down. The biodiesel is just a happy side benefit that makes the whole project worthwhile. Being environmentally friendly isn't always bad for business.

    I've always thought a method like this would be useful in treating sewage wastewater. I bet you could get enough energy out of this to take the water treatment plant off the electrical grid (Okay, this was just a wild guess with no actual numbers for reference, but seems reasonable.) My thoughts were to directly take energy from bacterial digestion of the waste products, but making biodiesel would help alleviate the need for petroleum in transportation.

    Hmm... but then again I question what the actual environmental gain would be on this. Any pollutants eaten up to make the biodiesel would have to be chemically removed from the stream (probably prohibitively expensive) otherwise they'll just come out of the tailpipe of the bus or whatever the diesel is powering. Might be more efficient to just use the fossil fuels to power the bus and use solar energy to power the electric grid. Otherwise you would be able to use the diesel created through this to run the powerplant, and that just sounds like a violation of some of the laws of thermodynamics to me.

  4. Re:F/OSS = Popularity on The Death of Licensed Enterprise Software? · · Score: 1

    So to me the question is: who's going to care enough about mundane, boring, business-rules based code to keep it up to date? Certainly not me -- not for free. And therein lies the limits of F/OSS.

    Ironically if anybody is going to grow OSS, it's large businesses. Some businesses see value in using some OS code for their own use and returning some of their own code to the wild. Open Sourcing some software allows it to be developed without having to pay programmers for all of the work. Or perhaps the company views releasing their code for code they use to be a form of barter. It won't really work for all types of software, but some are very amenable to this treatment.

    I suppose the other place that OSS will continue to be extended is in universities. OSS projects make the perfect starting point for many research projects, thesises, etc. And not just within comp sci. ESRI, the de-facto standard in GIS software, was originally started by a couple of landscape design students (It's definately closed source, but just shows that other academic disciplines are very computer savy and reliant.) And a school's own payroll, record keeping, accounting, etc etc seems like a good place to start rolling business oriented software, and it might make sense to make it OSS as schools really are supposed to be contributing to the general knowledge base, not fighting over every scrap of IP they can get their hands on.

    I know many biology teachers, especially in the field of conservation, use and contribute to open source software in their field. Just take a look at these pieces of software. I personally like the summary for Sashimi: Looking for a way to interpret the mass spectrometry (MS) data from your last proteomic experiment? Need to quantitate proteins in your ICAT sample? Want some help choosing the correct protein/peptide assignments? What are you waiting for?!?!

    Another organization that seems like they should be amenable to open source, but I personally haven't seem much of is libraries. They do a lot of behind the scenes tracking of data and just plain providing terminals for patrons to work on. I'd think that OSS would tie in brilliantly with their philosophy (and budget) but somehow most libraries just don't seem to have been infected with the meme yet.

    I think there's something your forgetting about television. They are supposed to pander to the lowerst common denominator. You know why? The viewers are not the customer. The advertisers are the customer. The viewer is, get this, the actual product.

    Picture the TV networks as a fisherman. The advertiser is the customer who buys the fish. The viewer is the fish, and the television shows are the net that he casts. The thing is, most diners want tasty fish, so you use the kind of net that usually gets the tastiest fish around. In the case of advertisers, tasty fish are gullible viewers, stupid people who's purchases are strongly affected by the commercials they watch. So, the television networks cast the type of net that will draw in these tasty fish, and that's why the news is so dull and trite, why sitcoms just aren't funny, and why reality TV is the king of television. Because the viewers are the product, not the customer.

    I'd imagine that the story is pretty much the same with cable TV, even though the product has to pay a premium to be sold to the advertiser. Commercials are supposed to be appealing to gullible people, not intelligent and rational people. Movies are starting to head in the same direction with previews getting longer and longer, product placement, etc. As a larger portion of the studio's income is earned through advertising then the viewer becomes more and more product and less and less customer.

    Radio stations, same thing. That's why any free thinking, truly rocking station quickly gets replaced with cookie cutter ClearChannel programming. Because the advertisers want tasty fish. The sort of fish who are amused by "two annoying guys with wacky sounds and their bemused female sidekick with an occasional bitter tongue in the morning."

    RIAA, they're making plenty of money. And buying enough laws to make sure that the money keeps rolling in. The DIY or die indie scene has been rallying to take down the establishment ever since punk rock in the seventies, and guess what. RIAA just keeps getting more and more power by producing shittier and shittier music (but at least they are giving the consumer less choices. Seriously, most major labels are cutting back on the number of artists they are officially promoting.) Every now and then the major labels will come out with a new "artist" that looks to be a rebel, and so conforming to the teenage ideal of what a musician should be. That veneer is usually gone after a couple of albums and people start to see the strings that are really moving the puppet.

    Or it could just be that lawnmowers fire a natural trigger that had been installed by natural forces. Many insects take wing more often when a thunderstorm is on it's way in. The thunder could become a trigger to the birds that these insects will soon take flight. The sound of a lawnmower may be similar enough in a bird to provide the reaction which is essentially pavlovian, but on an evolutionary scale rather than behavior. There are probably basic pavlovian behavior modifications going on as well, birds learning that lawnmowers kick up bugs (or simply expose them by shortening the grass, or in the case of herbivores distributing plant clippings) and so get hungry at the sound of a lawnmower. Once fixed in a bird, the behaviour could even be passed down to offspring ala memetic rather than genetic evolution.

    Or it could be, as you were saying, that genetic predisposition to food search when lawnmowers are running makes birds more evolutionarilly fit in an environment where lawnmower expose food, and so "natural" selection favors these birds at this time.

    But with something as complex as behavior (remembering that all biological processes, even behavior, are at their roots chemical processes) it is most likely a combination of causes that leads to birds flying when lawnmowers are turned on: genetic predisposition and triggers with previous circumstances allow the birds to become more succesfull if the respond to this stimulus, through a combination of instinct, training and learning. And for me, the simple answer is that in any complex system, the answer will most likely be complex.

    And, honestly, the only thing that makes the act of environmental destruction immoral is our ability to sit back and ask whether it is the right thing to do. I think that is one of the key aspects of humanity that puts us above the natural world. Yes, we are from the natural world, and rely on it, but have the ability to make choices about what we do to it rather than just reacting to an ever changing environment. And the ironic thing about the human experiment is that if we fail on the ecological test and devastate the environment, life is flexible and diverse enough that it will probably find a way again. Just that humans won't make it to that next do-over. So environmentalists, when viewed on a long enough time scale, are simply humanists.

    There are fish that do this, and many do require the male of another species to "fertilize" the other eggs, even though no actual hybridization goes on. I believe there are hormonal triggers that are the relic of when the fish wasn't parthenogenic.

    However, these subspecies of fish generally do not last very long. Parthenogenesis is a good short term strategy as it allows higher rates of reproduction than sex. However, once you get into an evolutionary timescale these parthenogenic fish are not well equipped to adapt to changes in the environment.

    These clonal colonies of fish often spring up and die out in a relatively short period of time, often times taking out the original population that they were derived from, as their higher rate of reproduction allows them to compete so well that they drive the other to extinction (at least locally, such as in a given pond) In the case where they need the males to "fertilize" the eggs, this in itself is enough to prevent reproduction and cause eventual extinction.

    But then again there are many types of fish which can change gender, either almost at will (at least seasonally) or are always born one gender and then change when there is a need for the other (probably all born female, then males formed as needed.) In these case there really isn't a genetic factor in sexuality, it is simply a hormonal process.
