Because the liberals are massively uniformed and the true news is hidden from them by their one-sided reporting lame stream bias` media ! ***GE To Make BILLIONS From Obama Cap and Trade Scheme***
Breaking: General Electric in the position to make billions from Obama’s Cap and Trade scheme and is lobbying heavily for it’s passage. Not only are they the largest wind turbine generator maker, they are going to profit heavily from the “cap and trade” credits as possibly the sole “secondary market’ trader of these credits. Now do you understand the main stream NBC, MSNBC, CNBC fully supporting the Obama agenda, and the hate-filled, anti-conservative spew from their networks.
GE is embroiled in what perhaps could be the largest scandal in the history of this nation. Currently, GE and CEO Jeffery Immelt have spend millions in lobbying efforts to assure the passage of this dasturdly “cap and trade” proposal. And, as evidenced from the Shareholders meeting in Orlando, Immelt wasn’t in the mood for the boo’s and the questions that exposed the media bias from NBC and MSNBC (and CNBC) and their total shift from objective reporting to nothing but pure bias toward the Obama administration and their “cap and trade” scheme.

Then Janeine Garafalo did her “hit shtick” on Olberman’s show earlier in the week, it was obvious that his entire lack of response to her diatribe was in full support of GE corporate policy and Olberman was being the compliant little prick he is and following the company line. It is OBVIOUS as the nose on anyone’s face that the NBC networks, that includes MSNBC and CNBC are totally pro-Obama agenda driven, and are using the bully pulpit to promote his legislative proposals. In the back of my mind, I knew deep down that General Electric, as owner of the NBC network, was fully supporting Obama, was instrumental in his election, and had something to gain. However, I never quiet made the connection as reported tonight.
Under the Obama plan, the “cap and trade” credits will be issued to all producers of energy. GE is the largest manufacturer of wind turbines as well as other electical generation turbines used in coal, gas, atomic, and hydroelectic electricity generation facilities. With the Obama plan, those cap and trade credits would be issued by the Federal Government, and ultimately, traded just like any stock or bond. GE has apparently, created and entire unit with the Corporation that would deal in the Secondary Market trading these credits. First, they are going to take in billions of dollars from government contracts in wind energy. Second, they perhaps are going to have exclusive control over the secondary market for these cap and trade credits. That, in effect, puts GE in the catbirds seat for all energy produced in this nation as ALL “carbon emission” energy sourced are going to be subject to these carbon schemes. This includes ANY oil related, natural gas related, gasoline, diesel, and any other manufacturer that uses any petro-based component. That means every single plastic container, every car, every chemical fertilizer, every pesticide, every single thing you use will be subject to this scheme as it too, is made from a carbon based material.
(“We’re in an area right now that makes Watergate look like a Shirley Temple movie.”) illustrate, the best that can be said about General Electric is that it is hip deep in conflict of interest. It’s running TV networks that prop up liberalism, the global warming issue and Obama, while privately lobbying hard for cap-and-trade, from which it intends to profit heavily.
There can be no doubt that GE is up to it’s neck in this scandal. It is further evidence that WE THE PEOPLE of this nation are going to have to quit sitting still and allowing this huge, overblown government from dealing with GE for any contracts awarded to them for anything. Face some realities- GE is one of the governments largest contractors and they are going to get billions and billions more under the Obama plans should they become law. This, with no words minced, is an OUTRAGE to the foundation of this nations Constitutional government. Additionally, GE employees contributed to Obama’s campaign, close to $98,000 while NBC employees contributed close to $194,000. (For reference, the McCain camp only received donations close to $55,000 from GE/NBC employees according to OpenSecrets.org) They heavily invested in his election and the desire for his climate change initiatives to become law for a very selfish reason- massive profits.
There can be no doubt that the very reason NBC, MSNBC, and the MSM is fully supporting the “settled science” on climate change is GE profit driven. They stand to make BILLIONS from the promotion of the scam on the American people and the world.

Turbines come in many sizes and power ratings.

AND: If it were running at full, rated power, for 250KW (which is a very big one) it would have to have an input of over 342 HP.
AND: 342 HP equals 188 K ft.lbs per second or 11.3 M ft.lbs per minute.
SO: It is the energy that must go into it from the wind forces that turn the propeller of the turbine.
HOWEVER: The rotational speed is depending on the design of the coils inside the generator, the number of blades, their length and the rotational speed they can support. Please refer to the wikipedia site above for a discussion on these matters.
IF: We assume a rotational speed of 120 rpm or some such figure (you can get specifications from the manufacturers web pages) you can compute the torque by trial and error using the nifty little calculator or go to a site regarding formulas.
(The torque must be guessed at until you reach the right HP as given above – 342).
It turns out to be around 180,000 ft.lbs (180K ft.lbs) or torque.
Think those numbers are reasonable for a 250KW generator.
PS: If the speed slows down to 50 rpm, the torque must increase to 450K ft.lbs in order to keep producing the 250KW power output!

I definetly would need a years collection of books, including all the Jane Austen/Charlotte Bronte classics to keep me going 🙂

I would also basically need a full stock of food and water , some proteins, some carboyhydrates, some fats, and some minerals, so I was getting all the right nutrients so I wouldn’t die of scurvy, lol.

A trowel, to dig holes for the treasure 🙂
Veg seeds, I’m a practical person!
A hat, that sun is bad for you you know
MP3 player with head phones and wind up charger thing (do they exist for MP3’s?!)

A book on “Surviving on a desert Island for dummies” 🙂 Guess that is kind of cheating.

A manual on how to build boats.

Zac Efron to build the boat. (Aha =] )

HEY READ THIS ARTICLE … I have attached the link too … I like the question … Wanted to learn … So i looked up 🙂

Solar Power 101
Batteries

By Jeffrey Yago, P.E., CEM

This article is the first in a series of what will be a beginner’s course in solar electricty. Simultaneously we have instituted a Home Energy Information (www.homeenergy.info) section on our website where you can ask questions of Jeff Yago, the author of this series. Yago is a licensed professional engineer and certified energy manager who has writtten many energy articles for BHM. He has extensive solar thermal and solar photovoltaic system design experience, and is author of Achieving Energy Independence — One Step At A Time, which includes many solar system wiring examples. It is available from the Backwoods Home Bookstore or by calling 804-457-9566. Those interested in solar electricity will want to save these articles for future review when planning your solar system.

I am getting numerous requests from readers wanting very specific guidance on how to install their own solar electric systems. Many have already found that this process is a little like trying to build an automobile by purchasing parts from a NAPA dealer. For example, you can buy a brake drum, wheel bearing, and oil filter, but since your car does not yet exist, how do you know what parts you need, what parts will fit with other parts, and how should these parts be wired together.

During the next few issues, I will take you through the “basics” of solar system design and installation, and answer your specific questions as we go along. This course will continue on the Backwoods Home Magazine website (www.backwoodshome.com) under their new Home Energy Information (www.homeenergy.info) section. You will be able to e-mail your installation questions and offer suggestions for future home energy saving articles.

Before I can help you design your own solar power system, you have to understand that there are actually many different types of solar power systems, for many different applications.

System types
Some solar power systems are 12-volt DC due to the many low voltage RV and boating lighting and appliances available, and do not have a utility line connection. These DC only systems can be used to power several DC lights in a remote cabin, or a DC well pump in a field for watering cattle. Some solar power systems have an inverter to convert a 12, 24, or 48-volt DC battery voltage into 120-volt AC power to operate standard household appliances. Some grid connected solar power systems are designed for direct connection to your utility line and do not use any batteries at all.

Hybrid solar power systems can include a battery bank, a solar array, a generator, and even a wind turbine to provide power at all times with the utility grid serving only as backup. Inverters and solar arrays are available in many different styles, voltages, and wiring configurations. Some solar arrays are mounted on the roof, some on the top of a pole, and some are ground mounted, with each having different wiring rules.

If you visit a solar home that has a well designed and properly installed solar power system, you will find the concept is actually fairly simple. The hard part is knowing what wiring layout was best for this specific home, what size and quantity of each system component was required, and what wire size and fuses were needed to keep from burning down the house.

Batteries
One of the most misunderstood parts of a solar power system is the battery or battery bank, and that is where our class begins. Some solar battery banks use wet cells, like golf cart batteries, while others use sealed or gel cell batteries, and each have different temperature, mounting, and ventilation requirements.

Every battery is designed for a specific type of charge and discharge cycle. Car batteries have thin plates to keep their weight down and are designed for a heavy discharge lasting a few seconds, followed by a long period of slow re-charge. A 6-volt golf cart battery (size T-105) is the minimum battery I recommend for a residential solar application. You will need to buy these in “pairs” to make 12 volts. Golf cart batteries have very thick plates and are designed for hours of heavy discharge each day, followed by a fast recharge in only a few hours each night. This is similar to the duty cycle of a residential solar application, only in reverse. A solar battery must be able to provide long periods of deep discharge each evening and night, followed by a full recharge in only a few hours of sunlight each afternoon. Very few batteries can take a deep discharge-recharge cycle every day, and the 6-volt golf cart battery is the least expensive and easiest to find locally that can.

For some reason, everyone wants to use a sealed marine battery for their homegrown solar system. I strongly recommend that you do not. Included is a photo showing a sealed marine battery that “exploded” after being connected to a small solar charger for several months.

Even though this was a small 12-volt DC 5-amp solar charge controller powered from a single 50-watt solar photovoltaic module, this was enough energy to gradually overcharge the battery and evaporate all of the electrolyte even though this battery was “sealed.” A low electrolyte level can expose the plates which will gradually warp or “grow” in thickness as they oxidize. This can cause an internal short circuit and ignition of the hydrogen gas.

Plate damage can also occur when there is a large buildup of sediment after the upper plate areas become exposed from reduced water levels and begin to “flake” off. Most liquid acid batteries do not vent gasses while discharging. However, near the end of a typical charging cycle, when the battery is almost “full,” the sulfuric acid and water electrolyte will begin to break down into hydrogen and oxygen—a very explosive combination.

When ignited by a nearby spark or flame, an “explosion” can result, but this flash lasts only a fraction of a second, which is usually too fast to ignite nearby walls. However, this is still a very explosive reaction, with plastic battery parts becoming acid-covered shrapnel. While using a hand grinder one day in a shop, I accidentally directed the sparks towards several car batteries being charged about 30 feet away. There was a very loud explosive sound with acid and plastic hitting every wall of the large shop, yet I did not see a flame and there was no fire. Regardless, it was not a pleasant experience.

Always wear eye protection and acid proof gloves when working around batteries, and have lots of water and baking soda nearby. This will neutralize any acid spills from battery refilling and prevent further corrosive damage.

A typical 6-volt golf cart battery will store about 1 kilowatt-hour of useful energy (6 volt X 220 amp-hr X 80% discharge = 1056 watt-hours). Since this would only power two 50-watt incandescent lamps for 10 hours (2 X 50 X 10 = 1000 watt-hours), your alternative energy system will most likely require wiring several batteries together to create a battery bank. Since each golf cart battery weighs almost 65 pounds, there are weight considerations as well as battery gas venting issues to think about.

An area of a garage or storage building having a concrete floor is the most common location for a battery bank, although some large systems have their own specially designed battery room. I am going to assume you are installing a much smaller system and will only require four to eight batteries.

If you need more than the 220 amp-hr capacity contained in each golf cart battery, I suggest switching to the larger “L-16” size traction battery, having a 350 amp-hour rating, which may allow using fewer batteries. This battery is the same length and width as a golf cart battery, but is much taller and twice as heavy. This is an excellent battery for solar applications and can take very heavy charge-discharge cycling. This industrial rated battery may be more difficult to find, as it is only available from battery wholesale distributors.

Batteries can lose over half of their charge when exposed to extreme temperature swings, so be sure your proposed battery location stays in a 50° to 80° F range, or you will need to insulate the battery box. Since liquid batteries require refilling and battery terminal cleaning to remove corrosion several times each year, the floor area selected should be able to take an occasional acid spill and water wash down.

Battery venting is very important as discussed earlier, and if you build an enclosure around your batteries, it should be designed to direct all vented gasses to the outside. A 2-inch PVC pipe makes a good vent, but be sure it is located at the highest point in your battery enclosure where the lighter hydrogen gas will accumulate. Be sure it also includes a screened vent cap to keep out rain and insects. Do not locate your battery bank near a gas water heater or other open flame appliance that could ignite any accidental hydrogen accumulation.

A battery box can be built using standard 2 x 4 framing construction, with pressure treated plywood lining the interior surfaces. A hinged top door is needed for periodic battery maintenance, and should include a gasket to prevent gases from entering the room. Note how the top of the site-built battery box shown in these photos slopes up to a high rear area where two PVC vent pipes are located. The interior plywood surfaces of this wood frame construction were painted with several coats of fire and acid resistant paint. Since batteries lose capacity with lower temperatures, your batteries should not rest directly on a cold uninsulated concrete floor.

Pressure treated 2 x 4s on edge, spaced every 6 inches and covered by a fiberglass laminated concrete board, makes an excellent base for your battery box. This heavy sheet material is sold in most building supply outlets as a backing behind ceramic tile work in wet shower stalls, and is usually available in smaller 2-foot by 4-foot sizes. By careful planning, you may be able to use the entire sheet without cutting or splicing.

If you can afford to invest in the more expensive gel or absorbed glass matte (AGM) batteries, you will have more flexibility in locating your battery bank, since these batteries do not need to be refilled and do not normally generate explosive gasses. The photo shows a large battery bank with the batteries mounted close together in a vertical steel rack. You do not need a vapor proof enclosure or vent pipe when using these batteries, however they cost almost 30 percent more without providing any additional life or storage capacity.
