Some US Grid System Operators Curtail Wind Power by 33%

Leigh Hutchens — Fri, 16 Aug 2013 03:44:42 +0000

Wind turbines are being reduced to a third of their capacity by some grid system operators in Vermont, Maine, New Hampshire, across Texas, and parts of the Midwest. These grid operators are concerned that intermittent energy surges will overload the system. These curtailments, as they are called, are taking place because of the strong bursts […]

Atypical Design Leads to High Output, Cost Effective Wind Generator

Leigh Hutchens — Tue, 11 Dec 2012 08:12:39 +0000

One bright-eyed startup company, SheerWind, a Minnesota based company, believes its INVELOX system might just transform the wind industry. SheerWind asserts their ducted turbine can perform in wind speeds as low as 2 MPH, thereby reducing the cost of wind power to less than 3 cents per KWh. SheerWind also claims INVELOX has a minimal […]

65kW Solar Powered Micro-Turbine

Ovidiu Sandru — Sun, 03 Aug 2008 19:45:02 +0000

HelioFocus has ordered Capstone Turbine Corporation to develop and modify their C65 (65 kW) MicroTurbine to operate on solar power. HelioFocus has been founded in 2007, is based in Israel, and it produces modular, high efficiency Concentrated Solar Power (CSP) systems to convert the sunlight to electricity. They use a parabolic concentrator which focuses the light onto a solar receiver. The solar receiver is heat-based, and it drives Capstone's modified turbine.

Jet Engine-Like Wind Turbine – 4 Times More Efficient

Ovidiu Sandru — Mon, 31 Mar 2008 07:28:19 +0000

Here's an invention that should capture more of the world's attention, because it can capture more of the world's winds. Flodesign's "jet engine"-shaped wind turbine has a slightly different way of seeing the wind flow, and by this it is three to four times more efficient.

The Tornado Solar Tower: Get Power From Recycled Heat

Ovidiu Sandru — Sun, 10 Feb 2008 20:10:18 +0000

Did you know electrical power can be generated by using various sources, including the sun, wind, warm air from the ground? The list goes on… The most interesting is the tower resemblant to a solar tower, in which a controlled tornado is created. Engineer Luis Michaud, from Canada, who has proposed this system, has already […]

How a Slotted Disk Turbine Engine Works

Ovidiu Sandru — Wed, 06 Feb 2008 14:17:15 +0000

Introduction. The purpose of this paper is to offer the reader some insight into how a bladeless steam turbine can be constructed and used. The use of inexpensive slotted disc turbines in place of much more expensive bladed turbines can fill a void in the need to convert heat energy to electrical energy, and can […]
