New Plasma Switch for More Efficient Long-Distance Power Transmission

Arsenij Percov — Sat, 18 Aug 2018 20:10:11 +0000

The General Electric (GE) company is developing an advanced plasma switch that will make a conversion of high-voltage DC to high-voltage AC more efficiently, enabling reduced-cost transmission of long-distance power. Additionally, substations along the power route will reduce the voltage of AC current to low-voltage before it reaches consumers’ devices. We use low-voltage alternating current […]

The Harriet Gas Turbine – World’s Biggest, Greenest, Most Powerful

Mila Luleva — Mon, 23 Feb 2015 20:10:19 +0000

Harriet , world’s most powerful and most majestic gas turbine, capable of powering hundreds of thousands of homes, is now under final testing. If successful, the monstrous energy generator could provide a cleaner alternative if renewables fail- but will it really? It is very safe to say that the Harriet gas turbine is nothing like any other […]

General Electric Wind Turbine Blade Extensions Improve Efficiency

Benji Jerew — Tue, 27 May 2014 15:40:47 +0000

Wind turbines, or at least their predecessors, the wind mills, have been around for millennia, always improving their power and efficiency. Generally-speaking, however, the wind turbine efficiency improvements require replacement of some very expensive components. For example, old generators or transmissions can be replaced with more efficient versions. Recently, it has been calculated that larger […]

General Electric Magnetic Refrigerator 20% More Efficient

Benji Jerew — Wed, 12 Feb 2014 18:16:11 +0000

It’s an old idea, but General Electric’s advances in magnet technology could lead to a magnetic refrigerator that’s 20% more efficient than today’s refrigerators. Refrigeration technology has come a long way since the ice box. The first compressor-type refrigerators appeared in the 1920s, and advances in insulation and compressor and evaporator technology have led to […]

Electric Vehicle Range Anxiety Addressed by ARPA-E Funding

Benji Jerew — Thu, 22 Aug 2013 19:46:45 +0000

Electric vehicles are still gaining in popularity, but they still have some important limitations to overcome before they can truly go mainstream. Really, though, are the limitations mental or electrical? Overcoming electric vehicle range anxiety and reducing battery costs are the focus of a new program under some new funding released by ARPA-E [Advanced Projects […]

General Electric Turns to Ceramics For More Efficient Jet Engine

Benji Jerew — Tue, 12 Mar 2013 21:24:15 +0000

Jet engines run at the very edge of thermal meltdown, but General Electric is turning to ceramics to turn up the heat and make a more efficient jet engine. Jet fuel burns much hotter than even the toughest alloys, so air injected into the core cools things off. This keeps the engine from melting, but […]

Technology Helping Wind Turbines Overtake Fossil Fuels for Energy

Leigh Hutchens — Wed, 06 Feb 2013 23:08:25 +0000

Although wind turbines do not appear to have changed much over the years, the technology behind them has gotten considerably more sophisticated. This has led to the increase in the amount of electricity wind turbines can generate and has lowered the cost of wind power. General Electric’s 2.5-120 wind turbine is a leader in the […]

GE Dropping Plans for 25,000 Electric Vehicles in Their Fleet

Benji Jerew — Sat, 12 Jan 2013 08:17:49 +0000

Facing reality can be tough, even for big companies such as General Electric [GE]. Electric vehicles [EV] may not make sense for a lot of people, such as those who commute long distances and transport heavy loads. Additionally, EVs and charging stations are typically more expensive than their gasoline-powered counterparts. Many consumers find it difficult […]

General Electric Zero Emissions Bus Combines Li-ion, Na-ion, and HFC

Benji Jerew — Fri, 14 Dec 2012 21:17:07 +0000

In the last few years, electrified, zero emissions buses have become, if not common, at least accepted in cities around the world. One bus line in Milton Keynes, UK, runs a fleet of electric buses that recharge on the driver’s break via an inductive charging pad buried in the road. One limitation of the electric […]

GE Planning to Build 15 MW Wind Turbine – Their Biggest to Date

Ovidiu Sandru — Thu, 01 Sep 2011 07:10:08 +0000

There’s only one thing bigger than big: HUGE. General Electric is now planning to build a huge wind turbine that will generate a maximum of 15 megawatts of electricity, their biggest yet. Currently, GE already has the biggest land wind turbine, but this one will generate six times the power of the first, and it […]

GE Announces New Gas Turbine That Regulates The Electric Grid

Mike Sandru — Sun, 29 May 2011 19:37:33 +0000

As we have already said on numerous occasions, the problem with solar and wind energy is that it isn't available 24/7. Due to variations in the wind and solar intensity or presence, the energy generated would differ in quantity as well. So researchers have been looking for ways to store it for longer and have come up with geothermal and molten salt. Nevertheless, its incorporation into the grid also needs to be regulated.
