I think the largest challenge when it comes to implementing a new fuel source is the capital to get the chain implemented. That's where I see the government able to assist. By making the capital available. However, mandating that it be used can be difficult and I really hate it when the government tells me what to do.
One of the best things that can happen over the next few years is real competition between the various sources of fuels, and also the continued emergence of alternative energy sources. With all of the appropriate attention on the energy problem and efficiency, it will be interesting to see happens when/if natural gas and biofuels can begin to compete with fossil fuels. Will be a healthy development, and the sooner the better.
That's right, Beth. It's the next generation that will be dertermining where this goes. My daughter and her friends accessorize their iPod, iPads and smartphone. These devices have become part of how this generation presents itself to the world.
I have to agree with Rob. While I see where William is going with the idea of ubiquitous cloud computing, I still think there will be some preferred device that people will want of their own and not be fully dependent on some public access station to get to their data. Maybe it's just a small access card with a processor or some variation of a key. But there will be different models, with different bells and whistles, and people will want to be hands on with them.
Wow. I didn't realize China's oil company has reached that size. The important thing, as you say, is to pursue a variety of alternative sources for energy. Add to that, greater efficiency and it looks like we're going in the right direction.
You have a very interesting view on the future of devices. But I think it's like mass transit -- it makes sense, but people love their cars and they love the freedom to go where they want when they want. People love their devices, and besides, if you have your own device, you can use it while driving. I can't tell you how often I'm behind a car at a red light. When the light turns green, the car just sits there until I honk. We all know why. When I honk, the driver looks up from his or her device and them proceeds through the light.
Hi @Ann... Nope. 2212 was correct - 200 years from now: The date when we predict we will run out of dino-fuels. I'm an "innovation" guy so I'm for new inventions and development daily. But what I'm not for is demanding the hard-earned talents of scientists and engineers be directed by political gamesmanship. If there is a true, defined reason why we should scramble to shift to biofuels, I'll be in line producing college graduates for the cause.
The Petroleum industry was born in Titusville, PA in the 1850s. It was not a project that was funded or envisioned by the World Governments, but by inventor Samuel Kier. He was the first human to recognize the value of distilling petroleum for fuel. Now, some 160 years later, the "petroleum industry" is somehow the property of World Governments that struggle to control its supply. If we see ourselves still based on hydrocarbon fuels 200 years from now, then it would be prudent to experiment. But would it be prudent to stop using petroleum? Maybe we should have delayed the invention of the Babbage Difference engine in 1822 until we solved the Y2K problem... after all, Y2K was only 178-years in the future -- right around the corner. =]
Politics is concerned with Power. Science is concerned with Truth. As a scientist, when Governments seek to influence scientific decisions through the use of Power, it is our responsibility to debate the issue and demand the decision be based on Truth rather than Political Whim.
My question still remains. Why switch transportation to Biofuels?
William, as mentioned in several other comment threads in stories about bio-based materials, the problems of finding alternatives to dino-based fuels and materials are large enough that a multi-pronged strategy makes the most sense. It would be dandy if we could get rid of internal combustion altogether, but that's probably not going to happen for awhile. So long before 2212 (was that a typo for 2022 = 2012 + 10 years?) we're going to need all kinds of alternatives in the short term while we're working out long-term strategies that can hopefully eliminate environment-harming practices.
And while I'd rather not get into an argument here about whether we should be pursuing yet more dino-fuel extraction, even if we do so the Chinese may own it all in a few years anyway, especially if they decide to call in our loans. PetroChina just announced that it's become the world's biggest publicly traded oil producer, ahead of Exxon, giving them enormous clout:
Beth, the study found that the degree of adjustments that need to be made to the marine fuel supply chain would depend on the types of ship, engine, and biofuel, and the blend percentage. No retrofitting required: perhaps you are thinking about DIY retrofitting of car engines so they can run on ex-MacDonalds frying oil. That's a world away from the commercial biofuels industry, which is much father along in Europe than in the US. These commercial biofuels are considered drop-in replacements that would be gradually blended in the same locations--fuel bunker companies--that currently blend non-biobased fuels.
Hi @Rob: My comment about was about "ubiquitous" cloud computing. There are two primary things that folks physically carry along with them: (1) Their Data, (2) A Processor. With the "Cloud", number (1) is no longer necessary --- tapes, floppies, cds, dvds, thumb drives... no longer needed. The "ubiquitous computing" part is when everything has a processor embedded in it: The refrigerator, microwave, toaster, kitchen table, office desk, automobile dash, airline seat, clothing...
We started with One Mainframe to Many People, then One PC to One Person, then A Few Devices to One Person, then Many Devices to One Person, then we finally arrive at Many Devices to Many People. When we reach "ubiquitous cloud computing", you will not need to own and carry around an access device... you will be able to use any public access device to access your own data in the cloud. $$ will be collected by what you do with your data, not in exchange for the device used to access and manipulate it. In much the same way I do not need to travel with my own personal electricity generator. I just plug into any public outlet near my current location.
My question to the topic at hand is that I don't know "WHY" we need to spend time, money, and energy on legislation and incentives to change the supply chain, procurement practices, and cost structure from petroleum to biofuels if all we are doing scientifically, is using new carbon-compounds instead of old carbon-compounds -- a supply of which is growing rather than depleting...
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
