MIT says process could provide 10% of the electricity needs in America by 2050

Generating power from resources that don't create pollution is a major area of research around the world. The more power we can create from methods that have low pollution and don’t require fossil fuels, the less we as a nation will have to rely of foreign oil.

Researchers at the Department of Energy's Pacific Northwest National Laboratory (PNNL) have unveiled a new method of capturing more heat from low-temperature geothermal resources. According to the researchers, this type of geothermal resource is capable of generating pollution-free electrical energy.

The researchers are working to determine if the new method can safely and economically extract and convert heat from the geothermal resources into electricity. The ultimate goal of the project is to be able to produce electricity without generating greenhouse gas emissions and tap a currently unused underground geothermal resource.

PNNL Laboratory Fellow Pete McGrail said, "By the end of the calendar year, we plan to have a functioning bench-top prototype generating electricity. If successful, enhanced geothermal systems like this could become an important energy source."

According to an analysis conducted at MIT, the new power generating method cold produce 10% of the energy needed by the U.S. by 2050. The new process uses a special liquid that the researchers developed called a biphasic fluid. When the fluid is exposed to heat brought to the surface from water circulating through moderately hot underground rock the biphasic fluid undergoes a thermal cycling.

This thermal cycling can be harnessed to power a turbine that generates electricity. The scientists have developed a nanostructured metal-organic heat carrier called MOHCs that are able to boost the capacity of the generators to levels near that of steam cycle. The advancement was discovered while working on an unrelated project at the labs.

McGrail said, "Some novel research on nanomaterials used to capture carbon dioxide from burning fossil fuels actually led us to this discovery. Scientific breakthroughs can come from some very unintuitive connections."

Wow, so in something like 40 years this may, possibly, be producing some electricity. It isn't even working on a test bench yet but it is breaking news on Dailytech? Why? Headline this, I plan on putting a turbine in my toilet and use the swirling to create electricity. In 20 years I should be able to supply 10% of my household energy. I'll have a bench model soon.

Brilliant input troll.

I can't fault your plan there - gravity is free and in abundance after all.

Might need a good fuel filter on that turbine mind...

I'm serious here - me and six neighbouring cottages have their waste water coming through one pipe into a sess pit...

Scale it up and on a moderately large WTP you could have a turbine sitting there being powered by waster water from tens of thousands of homes!

Thats not a bad idea. Maybe you could try to capture the heat and methane coming off of the waste too?

how often would you need to flush the toilet to even generate 1% of your power needs?

Hmm, adds a whole new meaning to the term "when sh1t hits the fan"

I am intrigued; please tell us more about your poop turbine design!

Interesting idea, but you'll pay for it in increased plumber visits.
