    A Glossary of Ecological Terms Terrapsych

    The glossary that follows assumes a definition of ecology--the study of interactions between organisms and their environment--much wider than what fits under the field's habitual statistical persona.Ecofeminism and ecopsychology are mentioned, for example, as are terms from organic gardening and permaculture....

    The Murray Darling River is facing a plethora of publicity: fish deaths due to mismanagement of flows by the responsible body, farmer agitation as a result of loss of irrigation water, claims that the water buybacks behind the farmer concerns have been at excessive prices and possibly corruptly made, and a report by the "Wentworth Group of Concerned Scientists" with the usual claims of ...

    Australian Coal Power Will Be Quickly Killed By Low Cost

    Last month the entire country sweltered under an oppressive heatwave — except the half known as Western Australia. As air conditioner power consumption soared on the 25th, 40% of Victoria's coal generators failed followed by rolling blackouts. When faced with this incontrovertible evidence of coal's unreliability, the government dedicated itself to the rapid phaseout of coal under its ...

    Hugh Piggott's blog | Scoraig Wind Electric News

    A friend has suggested that I flag up the consultation that is taking place in the UK about this new method of support for grid-connected renewables including wind and solar. "I think this is an important consultation for small grid-connected wind, because the potential for time-of-day and even spot market export tariffs could make owning a turbine much more attractive for crofters, farmers ...

    How it works? Vortex Wind Turbine in a Nutshell

    The disturbance of the downstream wind current is why regular turbines need to be installed far from each other. This doesn't affect bladeless wind turbines, any limitation associated with the "wake effect" is avoided. Furthermore, we expect Vortex devices to work better together, feedbacking each other if they have the proper free space around them, which is estimated to be half of the ...

    Wind turbine Wikipedia

    A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical energy.. Wind turbines are manufactured in a wide range of vertical and horizontal axis. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs....

    How the hydrogen economy could make a comeback The Engineer

    The vertical axis design also has the advantage that the same force is acting on both the concave and convex side of the blades (either side of the vertical axis) so, whilst it may not be as efficient as the children's windmill, it has a self-braking effect and can still produce energy at high wind speeds when the normal wind turbines would have to be turned at right angles to the wind....

    About me | Zerocarbonista

    Oh hello Simon! It's been a while since we last chatted on here!. The simple issue, it seems, is that you do not wish to pay for the electricity you have used. Your claims of being a victim of some bad practice or other are all false – we've bent over backwards to accommodate you, yet you've been unwilling to pay the £20 a month we agreed with you and set up three years ago....

    Water lifting devices fao

    Because the power in the wind is so much more sensitive to velocity rather than to air density, the effect of altitude is relatively small. For example the power density of a 5m/s wind at sea level is about 75 watts/m 2; however, due to the cube law, it only needs a wind speed of 5.64m/s at 3 000m a.s.l. to obtain exactly the same power of 75 watts/m 2....

    Cost-effectiveness & feasibility analysis Vortex Bladeless

    The aim of the table above is to introduce about the topic of the real output and efficiency of different turbine technologies. Normally, electric machines are expected to work in design conditions, which mean that most of the time they should be working at nominal power. However, wind turbines at the ground level seldom reach their nominal power peak since the high wind speed required is not ...

    How does wind energy work? – ExploringGreenTechnology

    The most common wind electricity-generating method is using wind turbines. The wind turns large turbine blades, which spins a generator shaft and produces electricity (more about the parts of a wind turbine). The electricity can then charge batteries, be connected to a building's mains power, or connected to the national power grid.. Wind turbines come in all shapes and sizes, from large ...
