Hydroelectricity

Hydroelectricity
Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010,[1] and is expected to increase about 3.1% each year for the next 25 years. Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. There are now four hydroelectricity stations larger than 10 GW: the Three Gorges Dam and Xiluodu Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela.[1] The cost of hydroelectricity is relatively low, making it a competitive source of renewable electricity.

Phone Charger Uses Crystal Orbs to Focus the Sun's Rays A $149 solar smartphone charger called Beta.ey features a ball lens and minuscule multi-junction solar cell that can charge a smartphone one and a half times per day. RawLemon The theory underlying the project is that gleaming crystal globes can concentrate diffuse sunlight, or even moonlight, onto a tiny, hyper-efficient photovoltaic cell.

30-Blade Eco Whisper Wind Turbine is "Virtually Silent" YouTube/Video screen capture Want wind power, but think that those tri-bladed behemoths are just too loud? Well then, Australia Renewable Energy Solutions has just the thing for you: The Eco Whisper wind turbine. This sharp-looking little contraption may only have a 20 kW generating capacity, but the company claims that the turbine is "virtually silent". Natural Gas Natural gas is a fossil fuel formed when layers of buried plants, gases, and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in natural gas. Natural gas is a nonrenewable resource because it cannot be replenished on a human time frame.[1] Natural gas is a hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes and even a lesser percentage of carbon dioxide, nitrogen, and hydrogen sulfide.[2] Natural gas is an energy source often used for heating, cooking, and electricity generation. It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals. Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates.

Hydroelectricity - How We Get Hydropower Energy Hydroelectricity has been around for close to 100 years. Hydropower energy has been utilized for over thousands of years. In the United States, hydropower energy is the primary source for electricity. How does it work? Hydropower uses flowing water to create energy that can be captured and turned into electricity. Creating Plastic Out of Thin Air Newlight Technologies co-founder Mark Herrema shows off AirCarbon pellets | Image credit: Dan MacMedan/USA TODAY We’re hearing more and more often about inventive new ways companies are turning waste into valuable resources — from turning everything from CO2 and methane gases to human and food waste into fuels, and plastic into bacteria-battling “ninja polymers.” This week USA Today explored another breakthrough — a process that extracts carbon molecules from methane gas and turns them into plastic. California-based startup Newlight Technologies is using captured methane gas from dairy farms and turning it into AirCarbon, a durable and versatile plastic that can be used in everything from furniture and food containers to auto parts. According to the article, AirCarbon removes more carbon from the atmosphere than its manufacturing emits, making it a carbon-negative material. Already in the works?

Wilderness Shanty Wood Stove This is a new stove from a new supplier We no longer have the outdoor wilderness ice shack wood stove. But we have a new ice fishing shack shanty wood stove heater This stove is made from 16 gauge metal.It has a 4" pipe for the chimney..That sticks out of the top 2" high.Chimney pipe not included.. The wood box is 15" long X 8" wide X 8" tall.The REMOVABLE legs hold the wood stove 4 1/2" off the ground.Raised handle for easy access to firebox.has a damper control. Also a metal door locking mechanism.Has a flat top,Good for a small fry pan to fry fish or any food.. Biofuel A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers to recently living organisms, most often referring to plants or plant-derived materials).

Wind Power Information, Wind Power Facts Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And as long as the wind blows, people will harness it to power their lives. Ancient mariners used sails to capture the wind and explore the world.

Hydrogen Hydrogen gas was first artificially produced in the early 16th century, via the mixing of metals with acids. In 1766–81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance,[8] and that it produces water when burned, a property which later gave it its name: in Greek, hydrogen means "water-former". Industrial production is mainly from the steam reforming of natural gas, and less often from more energy-intensive hydrogen production methods like the electrolysis of water.[9] Most hydrogen is employed near its production site, with the two largest uses being fossil fuel processing (e.g., hydrocracking) and ammonia production, mostly for the fertilizer market.

Wind Power Wind power can be an excellent complement to a solar power system. Here in Colorado, when the sun isn't shining, the wind is usually blowing. Wind power is especially helpful here in the winter to capture both the ferocious and gentle mountain winds during the times of least sunlight and highest power use. In most locations (including here) wind is not suitable as the ONLY source of power--it simply fills in the gaps left by solar power quite nicely. Build your own! Building a wind generator from scratch is not THAT difficult of a project.
