Quote from: Svirin Kerath on November 26, 2007, 07:05:38 pmAs for wind, yeah, there are a lot of windy places. But it would require a lot of towers to actually use enough of it to be effective, which costs a lot of money, and they're pretty delicate, so maintainance would be a feck, which is more money.As supplemental sources of energy, sure, they don't hurt, but they don't generate nearly enough as oil as cost-effectively. thus, not too practical at the moment.As for compressed air, "Compressed Air: Take the combustion out of the internal combustion engine." sounds like a political slogan, not a scientific explanation. Like, "we only use 10% of our brains."The Soldat Forums is a place for elaborate, sophisticated scientific discussion. if you're going to bring up some weird new technology, the burden of proof is on you, explain it, link it, don't be a lazy ass and expect us to.The combustion engine uses pressure from the explosion inside to push pistons, instead of that, you use compressed air to do the same thing.Also you are still an idiot who has no idea what you are talking about. Wind energy is one of the cheapest energy sources to produce. Cheaper than coal.

Wind energy is one of the cheapest energy sources to produce. Cheaper than coal.I don't think you really understand what I'm saying. Wind is free, I know that much. Coal costs more to mine and refine than wind, which turns turbines for free. I'm talking about maintainence and production of the towers themselves, not wind. You would need a veritable fleet of them to harness and produce enough energy. The source is boundless and cheap, it's the mechanical considerations I'm taking. With that fleet of thousands you now multiply points of failure in machines that, when cheaply built, require little to cause a malfunction. If they're not cheap, they still require maintainance, and again, multiply that by thousands. That costs a lot of money.Compressed air looks good, but like many of the other things, requires more time and investment before it'll take off. 50 mile range isn't very good though, if you're dependent on a recharge afterwards. But again, time may see it become more practical.
I know. Including maintenance. And building. Wind is one of the cheapest energy resources available.Edit: Cars today suck ass in terms of efficiency. Right now cars are big and heavy when they don't need to be. also turning that drivetrain wastes a lot of gas. Using electric motors rather than a huge engine and a drivetrain, a lot less power is wasted.The ford model A Is an extremely light and maneuverable car; a car the industry should model their cars after from now on. You could drive through a ditch and through snow with those big tires with no problem, without Four wheel drive. The only problem there ever was with that car was that it had awful breaks, it didn't use hydrolics so it was as hard as you could press on that petal to slow it down.Point is, way back then they had the right idea, don't waste engine power on moving a big hunk of steel. Especially now that we have carbon fiber, Plexiglases and very strong light composite materials that can be safe.

From the book I read, Wind power can cost just over 7 cents per kWh. While geothermal is the cheapest, Wind is very cheap, cheaper than nuclear, solar, natural gas, hydro and biomass.Secondly Turbines employ more people than other fuel sources. More jobs is a great incentive. It costs far less than gas wood oil and waste.That source was possibly the most biased piece of feck ever. Wind energy is plentiful enough for it to be a dominate source. Any country with a coast can utilize wind energy. That site is so full of bias that it is unusable as a source.
We have these people called engineers who make things so that they don't feck up. If anyone tells you that a wind tower takes a lot of maintenance they are full of feck. Just ask the people who have residential units.What I am trying to tell you is that the sources you point to have no idea what they are saying. Those people don't know feck about Nuclear advantages and Disadvantages, or wind or solar.
I have read 3 separate books. In one, the man set up his own wind turbine, had it for years, all he ever does is knock the ice off of it in the winter. Zero problems, much like everyone who has ever commented on the subject has said. Engineers build things to be efficient, they wouldn't be sold for hundreds of thousands of dollars if they fall apart. One building program estimated that the wind turbines would last 30 years before needing major restoration.Your report is full of lies.
See above post
Also they don't mention another form of solar, which creates molten sand to power a turbine.
Quote from: a-4-year-old on November 27, 2007, 10:01:36 pmAlso they don't mention another form of solar, which creates molten sand to power a turbine.This is sand. It is made primarily of silicon dioxide. Silicon dioxide melts at 1650C. In short, I call bs.
NuclearWe've had this for a while, it's not quite safe, and creates a ton of dangerous waste.
QuoteNuclearWe've had this for a while, it's not quite safe, and creates a ton of dangerous waste.Im sorry If Im off topic but this is such a bullfeck... I mean, the Nuclear plants are pretty safe...maybe not 100% safe but aint too dangerous. More ppl died from obesity,cancer and car accidents in US than in Chernobil [and whole EU] after explosion in Chernobil nuclear plant.

They melt salt, not sand.Lots of mirrors pointed at a tower magnifies the sun's energy which is what generates heat that powers the turbine; it is called solar thermal.Oh and Svirin, I call your one report laughable because I have seen so many people and so many books say that it is low cost and low maintenance. http://www.mge.com/environment/wind/ wind turbines said to last 30 years, these turbines will outlive most of the appliances they run.
Svirin, When they say "possible" I could use the same word to say that violating the laws of physics is also "possible" There is a failsafe that stops any meltdown before it can become out of control, it is incorporated into the design of every nuclear power plant in the US. Also there is a program for treating the waste that would mean that civilians are not in danger of coming in contact with nuclear radiation.
"That's not an inaccuracy or bias, unless you can prove that they knew that and neglected to say so."It would be either a bias, or a proof that they don't know what they are talking about. If they had the information and failed to note it, then it is a bias, if they never had the information, then their entire research is flawed.
"Panels will work in cloudy weather, but they are not nearly as effective." How much is not nearly as effective, because I seem to remember that they still collect a lot of energy. Still solar power can be used around the world.
Small scale Geothermal can be used anywhere where the ground temperature is about the same all year round and not a tundra, by pumping water through the ground, you can use the ground to heat up the water and then a heater to heat it up to the desired temperature, but after installation (which is mainly in newly constructed buildings) it is essentially free energy with no pollution.
Lets talk about more inaccuracies. Wind:Advantages * Inexhaustible fuel source * No pollution * Often an excellent supplement to other renewable sources (this is not just a supplement, wind is plentiful enough to power the world by itself if we built the towers. see lower)Disadvantages * Very diffuse source means low energy production--large numbers of wind generators (and thus large land areas) are required to produce useful amounts of heat or electricity (Some of this is true, but they fail to point out that even though wind farms take up a lot of land, towers themselves are not actually taking up much of that land, what happened at one site was that the tower was built on a person's farm, and they were paid for a portion the amount of wind the turbine produced This setup means that everyone wins, since wind energy is so cheap, consumers win as well) * Only areas of the world with lots of wind are suitable for wind power generation (not true, some generators are designed to run best in high wind, but some are for very low wind, such as a VAWT type turbine, many subtypes run in low wind which makes it ideal for any location, except they cannot interfere with bird migration. Also offshore and near shore are very effective, from the statement, you can infer that this is somehow a problem, but since there is so much land that is suitable for wind energy, in reality it is not a significant disadvantage.) * Relatively expensive to maintain (as stated numerous times; wrong. Wind energy is one of the cheapest available, the money spent on building and maintaining a wind turbine is very little compared to building a dam for hydro, or the tedious process of getting through the red tape and treating waste products Note: not that it is unsafe, but it does cost a lot more than wind power)
Next: GeothermalAdvantages * Theoretically inexhaustible energy source * No pollution * Often an excellent supplement to other renewable sources (in some areas of the world it can be the dominate fuel source for the area see: greenland) * Does not require structures such as solar panels or windmills to collect the energy--can be directly used to heat or produce electricity (thus very cheap) (Geothermal is a cheap source, but this infers that wind is not a cheap source, which is a fallacy)
Disadvantages * Not available in many locations (true but as before, it can be used effectively as the main source of power in the locations that it is used) * Not much power per vent
Fusion has not had a breakthrough yet, I won't comment on it until it is actually used a source of energy.
http://www.awea.org/faq/wwt_costs.htmlnote the 5 cents per kWattI have no idea where you found that quote. Five cents is vastly cheaper than it's polluting counterparts.http://fcgov.com/utilities/wind-faq.phpone cent per kWhhttp://www.fplenergy.com/renewable/contents/faqs_wind.shtml#sourcesWhat's this? another source? no... can't be."Wind turbines generally require preventative maintenance checkups two to three times per year."also note price 4-7 cents per kilowatt
