http://news.bbc.co.uk/2/hi/science/nature/4629239.stm What is all this nonsense about what 'we' are going to do about new energy sources? What is the most that 'we' are ever going to do--vote for a new 'Energy Czar' to head-up our worldwide Centrally Planned Economy, and then sit back while...

hello people, gday everybody! I am a first year engineering student and we just got an assignment where we have to make a desalination plant. The restrictions on the plant are as follows: - plant must be within the confines of 1m by 1m by 0.5m - plant must ONLY using the sun as a source of...

How long does it take for a nuclear power plant to be built and to have its first reactor come on line? Let's start the time line at basically when the permit is requested and end it when the first reactor goes fully online. What kind of time period are we looking at there in the best case...

There were no pictures available , i wonder why..?? try googleing Yards Creek Power Plant what a waste of power..!

i have to calculate the entropy for a power plant. to calculate entropy i have to get some data for the power plant 1.) net power output 2.)the type and amount of fuel 3.)the power consumed by the pumps, fans and other auxiliary equipment 4.)stack gas losses 5.) temperatures at serveral...

My garlic started to sprout, so I just decided to plant it.. it is growing some really nice roots and a stem already :approve: I just wonder whether it will grow into something nice or will just look (and smell) terrible in the living room? Actually what I wanted to ask: can you grow a...

Hi The BNFL plant at Sellafield in the UK is reported to have ‘lost’ 30kg of plutonium in the reprocessing nuclear fuel. It is reported as a paper loss due to the limits of accurate measurement within the process. Due to the lack of information in the news reports I am left a little confused...

Does anyone have aquarium? I just bought 120L tank with all the equipment for 200$. I want to have only plants in my tank. Do you guys have any experience with keeping plants in aquariums?

Seriously Stuck.. A coal fired plant generates 600MW of electric power. The plant uses 4.8 x 10^6 kg of coal a day. The heat of combustion of coal is 3.3 x 10^7 J/kg. The steam that drives the turbines is at a temperature of 573K, and the exhaust water is 310K. 1.) What is the overall...

Carnot Cycle is the ideal heat engine cycle with maximum efficiency. We use Rankine Cycle as the working cycle for steam power plant which has significantly lower efficiency that Carnot Cycle. My question is why we don't adopt Carnot Cycle as ideal Steam Power Plant cycle? Thanks in advance!

Theres a plant out there called "Salvia Divinorum". It's legal, and is usually smoked in extracted form.. It's a perception altering drug. I frown upon any kind of drug abuse or abuse to the human body, but this drug is truely amazing as to what it does to the mind, and i believe research...

Last decade ice core digging in the West Antlantic Ice Sheet (WAIS) gave a big surprise. Diatoms in the mud under the ice sheet revealed that there has been a sea bottom with a maximum age of some 500,000 years but possibly younger. http://www.sciencemag.org/cgi/content/full/281/5373/82...

What Is Meant By Totipotency (in Relation To Plant Tisssues)

will the plant's respiration rate increasing while the plant is taking photosynthesis?

Guys i need to submit an assignment in "PLANT PROTEOME ANALYSIS". Does anyone know any good sites/online books regarding this ? PLease Help !

No one hears this. They go on and on about evolution, oblivious to the fact that evolutionary theory does not deal with consciousness one way or another. If the conclusion is that plants can be fully explained in evolutionary terms and therefore are mere "automations," then why does that...

I know that some of the isotopes have extremely long half-lifes. However, isn't it true that generally speaking, a longer half life correlates to a lower rate of radioactivity? So wouldn't the most dangerous elements be those with short half-lifes? Isn't most of the danger from waste therefore...

I am wondering about the differences between plant vs animal cell division, mainly about cytokinesis. Is the following a true generalization? Plant daughter cells separate by forming membrane vesicles that line up in the center of the cell and fuse to form new plasma membranes. Animal...

Here's an interresting poll for you all. The government has decided to build a power plant nextdoor. You have no way to convince them to put it elsewhere (just assume you drew the short straw). You also don't have the means to move away for at least 10 years. They do give you the choice...

I have a few questions that i need help understanding how to answer: 1. At a power plant, the operating temperatures are 700 C and 310 C. The efficiency of the plant is 65% of its Carnot efficiency. The output of the plant is 500 MW. a. Determine the efficiency of the plant. b. What is the...

Hello! A coal fired plant generates 600MW of electric power. The plant uses 4.8x10^6kg of coal a day. The heat of combustion is 3.3x10^7 J/kg. The steam that drives the turbines is at temp of 300 degrees C and the exhaust water is at 37 degrees C. Whar is the overall effiecy of the plant...
