    Can You Successfully Grow a 30-Ft Tropical Vine Indoors?

    so i want to grow a tropical plant indoors im thinking about buying some plexiglass, a lamp, a fan,soil, and something to keep moisture in the air and growing it in there. i was wondering if there were any guides to this, or if i should just experiment (different moisture/light/air flow)...

    Nuclear power plant at 34% efficiency - rising temperature of water

    A nuclear power plant generates 500MW at 34 percent efficiency. The waste heat goes into the connecticut river with an average flow of 3x10 to the 4th kg/s. How much does the water temperature rise? (it requires 4.8x10 to the 3 to raise the temperature of 1kg of water 1K

    Practical size limit to nuclear power plant?

    Assuming the current anti-nuclear public/political climate remains in place and no new nuclear plant sites would be allowed (nor within a reasonable timeframe) why not just simply increase the existing capacity? For a hydro plant it makes sense there is only so much water that can be...

    Did Tobacco Industries Use Uranium Tiles for Plant Growth?

    Uranium Tiles and tobacco plant growth Someone told me a few years back that tobacco industries have used uranium tiles to help grow tobacco plants. I wasn't sure about this so I decided to throw the topic at my biology professor in case he knew something I didn't. I don't know if this is...

    Calculating Coal Usage for a 1000 MW Steam Power Plant

    At a steam power plant, steam engines work in pairs; the rejected heat from the first is the heat input to the second. The operating temperatures of the first are 670 C and 440 C. The operating temperatures of the second are 440 C and 290 C. Assume both engines work at 60% of their Carnot...

    What is a Radioisotope Glove Box?

    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...

    What is the significance of pursuing reversibility in power plant processes?

    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!

    Can Plants Possess Consciousness?

    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...

    How long is nuclear power plant waste really dangerous?

    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...

    How Does Plant Cell Division Differ from Animal Cell Division?

    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...
