Magnalight Introduces Stainless Steel Hazardous Location Lights for Corrosive and Salt Water Areas
Feb 16th
Dallas, TX (PRWEB) June 4, 2009
The stainless steel housing, neoprene gasket and high impact acrylic lens in the stainless steel hazardous location light are appropriate features for distillate plants, off shore drilling rigs, chemical preparation areas, wash down areas, etc. This Class 1 Division 2 light also meets US Coast Guard specifications, so it can be used on marine loading docks, ship yards and ocean going boats.
The HALSS-4-2L is a heavier duty, stainless steel housing alternative to our HALP-4-2L, which is a lighter duty hazardous location light with a fiberglass housing,” said Rob Bresnahan, President of Magnalight.com. “Both are More >

Answer by redblade20xxGeothermal comes from the earths internal heat in the US its much more easier to tap those other sources than drill a huge hole in the earth.

How To Pick the Most Beneficial Hot Water Heaters
Article by Shellie Schulz
The function is just not actually high-priced and it can save lives. Owing to its’ big water source capabilities, numerous choose to buy a 75 gallon water heater to give hot water towards a commercial structure or really massive house. If you are wishing to get one, how do you uncover a very great model in the ideal value? Below are the primary aspects to think about. 1) GPH recovery standing. This rating tells you what number gallons of hot mineral water the model can generate in More >
Lucid Energy Inks Agreement with City of Portland, Portland Water Bureau and PDC
Dec 18th
Portland, OR (PRWEB) October 18, 2011
Lucid Energy Inc., a renewable energy technology company and pioneer in the development of in-pipe hydropower systems for large water users, today announced that the company has signed an agreement with the Portland Development Commission (PDC) and the City of Portland, Oregon to partner on the development of a hydropower system within the city.
The partners plan to collaborate with the Portland Water Bureau on a project that will use Lucid Energy?s patented LucidPipe? Power System, a unique, in-pipe turbine that captures energy from fast-moving water inside of gravity-fed water pipelines to produce clean, More >

Best answer:
Answer by BobbyWell, i actually saw a doccumentary about Egyptians using flowing water with pyramids, that it created an electrical current strong enough to even light up a bottle with wet conductive materials (eg, wine bottle with paper) and so they arranged pyramids to be power conducters, based on how they were built with insulation (and so on and so fourth explanation, look it up)
But mainly, using it for hydroelectric power, from there, with the water turning the wheel to create energy.

Why do we rely on geothermal, wind, solar and water energy sources?
Dec 18th
Question by : Why do we rely on geothermal, wind, solar and water energy sources? What do they provide for us? Only electricty and warmth, right? Thats all i can think of them providing.
Best answer:
Answer by Marilou SmithThe sun not only gives us light at daytime but it is a major renewable energy source. In fact even in the old times they already harness the power of the sun for hot water and power for some appliances with solar panel. Aside from the sun we also generate renewable energy from the wind. Turbines converts to electricity the force that the wind More >
How much heat energy, in kilojoules, is required to convert 50 g of ice at -18 C to water at 25 C?
Dec 11th
Question by Anthropomorphic: How much heat energy, in kilojoules, is required to convert 50 g of ice at -18 C to water at 25 C? I don’t understand how to make them equal each other then get the heat energy of each one. I know the equation q=mxC_sxchange in temperature but can’t figure out how to use it and what to plug in where. I also know the change in enthalpy of vaporizaiton is 2250 J/g and the enthalpy of fusion is 334 J/g. Also the specific heat (C_s) for ice is 2.09 J/g degress C and the specific heat for More >
Why, most exactly, do water molecules give up energy when they form hydrogen bonds with other water molecules?
Dec 9th
Question by kooky45: Why, most exactly, do water molecules give up energy when they form hydrogen bonds with other water molecules? When water molecules form hydrogen bonds, when condensing from water vapour to liquid water for example, they give up energy in an exothermic reaction. What exactly is it about the molecules that is the cause of the energy release? Is it a change in the electrons bound to the hydrogen and oxygen atoms that are involved in the bonds? Do they jump to lower energy levels and give off energy as photons? Or is it another mechanism? Dr. Greg, thank More >
If water gives of heat energy when it changes from a liquid to a solid due to latent heat how does it ever man
Dec 8th
Question by firedon1000: If water gives of heat energy when it changes from a liquid to a solid due to latent heat how does it ever man If water gives off heat energy when changing states from a liquid to a solid due to latent heat how does it manage to ever freeze. We are talking about the same type of heat energy that drives hurricanes so this is no small amount of heat ?

Answer by arbiter007Huh??
Giving up heat means it gets COLDER.
