Mars Technologies Spawn Durable Wind Turbines

A technology built for Mars supports the demand for clean energy on Earth.

In the early 1990s, NASA was planning for an extended stay on Mars, and scientists at Ames Research Center were concentrating efforts on creating a complete ecological system to sustain human crew-members during their time on the Red Planet. The group started looking at maximizing energy efficiency and alternative methods to make power on a planet that is millions of miles from Earth. They turned to a hybrid concept combining two renewable sources: wind and solar power technologies. Large surface temperature swings on Mars produce windy conditions; extreme examples are the frequent dust storms that can block nearly all sunlight.

2013 Create the Future Design: Sustainable Technologies Category Winner

The Paradigm Shift in Wind Turbine Technology

Glen Lux Lux Wind Power Ltd., Saskatoon, Saskatchewan, Canada

Imagine a renewable energy source that can produce energy at a cost comparable to natural gas or hydroelectric generators using fewer resources, while being environmentally friendly. Lux Wind Turbines are expected to cost less than half that of conventional turbines, and can be spaced closer together to extract more power with less land.

Retrofits Convert Gas Vehicles into Hybrids

NASA supercapacitor technology helps turn rear-wheel-drive vehicles into gas/electric hybrids.

One initiative at Glenn Research Center, the Hybrid Power Management (HPM) program, focused on joining new and mature technologies for optimal power systems applications in space and on Earth, with the goal not only to develop ultra-efficient space power systems, but also to advance HPM to address global energy issues.

Inverter Testing and Certification for Global Markets

Inverters/converters are a key element of most renewable energy systems where the power generated is not suitable to either be used locally or to provide power directly to the electric utility. Many renewable sources such as photovoltaics generate DC power, while some renewable sources such as wind turbine systems generate AC, but not at the same voltage and/or frequency required by the utility.

Microinverters Are Launching a Solar Renewable Revolution

Given that solar-photovoltaic (PV) generating technology has been around for decades, one might think its general application in commercial and consumer circles might be a little more pervasive. After all, it is clean, safe, and relatively simple. Ask any expert and it’s likely you’ll get a litany of reasons why it has not gained more general acceptance — implementation costs, tricky installation aspects, long ROI, performance, and reliability are just a few. Fortunately, there is a game-changing technology — microinverters — that is ready to push solar PV’s acceptance and application past many of the current barriers.

From Aircraft Wings to Wind Turbine Blades: NASA Software Comes Back to Earth with Green Energy Applications

You might think a wind turbine would have more in common with a plane’s propeller than an aircraft wing, but wind blades actually behave a lot more like wings than props. This fact has enabled a valuable spinoff from aerospace to wind energy involving the first software that NASA ever allowed to be commercialized as part of the Agency’s ongoing effort to transfer technology to U.S. business and industry.
