  1. Ethanol IS solar energy on On Electricity (Generation) · · Score: 1

    Ethanol is not the answer. ... The true answer is ... solar ...

    I hope I'm not the first one to point out that Ethanol is nothing more than stored solar energy. CO2 and H2 are combined with the help of photosynthesis into O2 and hydrocarbons (aka bio-mass). That reaction requires solar energy. When you extract energy from bio-mass by, for instance, creating Ethanol out of it, you're extracting what was once solar energy.

    Now, of course, there are a few more conversions in that route than going directly from solar energy to kinetic energy or electricity, but some means of bottling solar energy will always be needed; the sun doesn't shine 24/7.

    The biggest problem in turning grain crops into fuel; there are just so many uses for grain crops in everyday products that a slight increase in their pricing because of competition with fuels could force consumer prices up, masking the true cost of these new forms of power creation.

    There are several ways to manipulate this. The subsidy can be adjusted to change the backstop price. Or we could establish a different subsidy rate for edible grains vs. excess stover. Plus, as energy becomes more readily available, the market cost of energy products will drop, vastly affecting the backstop price.

    The big question is, as the price of energy drops down to the equivalent of $1/gal of gasoline, will this model still be sustainable? The prices he's quoting are for current prices such as $.05/kWh and $3/gal of ethanol. With all the energy this method produces, those prices are sure to drop.

    If we drop electric rates to $.02/kWh and ethanol and bio-oil to $1/gal and recalculate, his example of excess stover value drops from $483 to $193, and grain drops from $721 to around $250. That gives a backstop price of $1.67/bu, down from his utopian quote of $4.80/bu, and much less than the $3/bu as quoted for foodstock. So farmers still make more selling corn as food. The price of your box of Corn Pops will not be "the biggest problem."

    So, as energy costs drop, will it still be worthwhile, or will only the early adopters who have a system in place while energy costs are still high benefit? Still, it helps make the case for being that early adopter and getting the infrastructure in place...

    Have you ever used Delphi or C++Builder? The .NET API and the Borland Visual Component Library (VCL) were built by the same guy. .NET has the advantage of being his 2nd iteration, and C# the second iteration of Java, so his team had a chance to work the kinks out... Still, C++Builder/Delphi were vastly superior IDEs to VB6, not to mention that they didn't require programming in VB... (gag)

    Borland has even released a free (as in beer) version called Turbo C++ Explorer. Not expandable like the original C++Builder from a few years ago, but still very nice for writing simple Win32 apps. Installation can be a pain, but if you make it through that, you'll notice many similarities between its VCL and the .NET APIs.

    To avoid asking something that's already been answered, here's a synopsis of some of his more recent interviews.

    In Guy Kawasaki's Blog, he's asked:
    1. How do you make money with an Open Source product?
    2. What changes in the Open Source community's attitude have you encountered since you decided "to build a company" around MySQL?
    3. Do you compete head to head with Oracle or do you have different customers?

    9. Who fixes the most bugs?
    10. If MySQL ceased to exist as an organization, would MySQL the product continue?

    In InfoWorld, he's asked:
    1. Recently, a number of open-source developers have expressed their unhappiness with the Free Software Foundation (FSF) and the second draft of GPLv3. Are you concerned about a potential forking of the license as some people stick with GPLv2 and others move to GPLv3?
    2. How do you decide when MySQL needs to develop new features for the database and when to rely on the open-source community for those innovations?
    3. So, is open source then a more forgiving environment than the proprietary software world?
    4. What's ahead in 2007 for MySQL?
    5. What's the latest news on Falcon, the transactional database engine being developed by database architect Jim Starkey who joined MySQL in February?
    6. Is MySQL's current dominance of the open-source database market ever a cause for concern?

    In Forbes, he's asked:
    1. How is open source software influencing what the bigger tech giants like Oracle, IBM and Microsoft will do in the next year?
    2. Do open source firms that sell to large, proprietary software companies risk being dubbed sellouts by the community that's helped them develop their software?
    3. How do Oracle's recent open source acquisitions affect MySQL?

    1. What are your short and long term goals do you have for the MySQL database system?
    2. Realistically where do you think you will pick up quick conversions to enhance your immediate market share from your competitors? Later, how much market share must MySQL commercial versions have to pick up to have long-term viability?
    3. If you see your main opportunity is in the replacement of Oracle installations does MySQL match or exceed the forte of Oracle in the transaction per second processing? Are you now aimed at the lower end of the Oracle market installations? What will it take to be really competitive with Oracle at the upper end of the scale?

If not what is the salient argument for such companies to install MySQL over the competition? Since you are primarily aimed at the market willing to pay for your enhancements and support, do you see any advantage in offering a MySQL product that will undercut MySQL server from below?

By "supporting" Linux, they can get a toe in the door and start doing everything they can to convince their potential customer that Linux isn't a stable choice, and they should buy VxWorks instead.

    Not that I can blame them, entirely. VxWorks is a different class of O/S, as Linux has a much larger footprint, and isn't hard real time unless you add to that footprint with the real-time extensions (which could be described as a mini-O/S embedded within the Linux kernel).

    The HDCP Speicification (PDF warning), available from Digital Content Protection, LLC describes the copy protection mechanism in detail, including the key revocation mechanism. They don't turn keys off per brand-name, as many here assume. Each piece of electronics equipment has its own key.

    To summarize, the key vector is a 40-bit word that contains 20 zeros and 20 ones. That means there are [40:20] ("40 choose 20") combinations, or roughly 137 billion unique keys, enough for each CE equipment. Sender and receiver exchange key vectors and, using secret tables, compute a common 56-bit secret. To verify that they have the same sacret, the receiver sends a hash back to the sender, then waits for a stream. That effectively makes the time required to verify a valid key vector cost prohibitive for a brute force attempt, at least on the receiver side. Now, if someone wanted to brute-force a sender, it may be easier, but hackers want to be able to decode, not encode.

    The key tables, electrical traces, timeouts, and several other tangible things that could be used to hack a link or transceiver are mandated and audited by DCP before they grant a license for the real keys. In all, it looked pretty air tight in my review. The media controllers seem to have learned from past mistakes and are employing smart people now to develop their content protection schemes. Strong encryption is becoming the norm...

    What you're forgetting is, in a ski resort, the air compressor is at the bottom of the slope. That compressor generates waste heat, especially if its gas or deisel powered. But more than that, its pumping heat into the compressed air through the work of compressing it. That hot, compressed air cools in the tank, or the line leading up to the snow-making nozzles before it has to cool the water mist.
