New York City’s New Plan to Turn Sewage Into Heat


When you consider that New York City disposes of more water as waste than nearly 70% of the countries in Africa (accounting for over 340 million people) consume, you would hope that they’re doing something useful with it. And they have been. With some of it.

California Has Approved First Molten Salt Solar Power Plant


Molten salt technology was demonstrated at the Solar Two project

One of the biggest problems with solar energy is that the sun doesn’t shine 24 hours a day. This means that unless users are only planning on using electricity when the sun is shining, some form of energy storage system is required. Since storing excess electricity in rechargeable batteries isn’t really practical for large-scale solar power plants, another storage system is needed. U.S. utility-scale solar project developer SolarReserve has now received approval for the first solar power plant in California that uses molten salt technology to store the sun’s thermal energy as heat so it can generate electricity when needed, at any time of the day or night.

America’s Largest Solar Plant Opens in Nevada


Copper Mountain Solar Facility

While it is nowhere as large as Canada’s 80MW Sarnia Solar Project (which is the world’s largest PV plant), the US has just opened the country’s largest PV plant in Nevada. The 48MW Copper Mountain Solar Facility, initiated by Sempra Generation, began construction January this year and the facility was finished just a few weeks ago.

Underwater Turbines Could Harness a Massive Amount of Energy from the Mississippi


Underwater turbines could tap the Mississipi’s power.

Tens of thousands of turbines anchored to the bottom of the Mississippi River could someday provide more than a gigawatt of renewable energy, enough to power a quarter of a million homes. That’s the vision of Free Flow Power, a startup based in Gloucester, Massachusetts, that recently received preliminary permits from the U.S. Federal Energy Regulatory Commission (FERC) granting it the right to explore energy production at dozens of sites along the lower Mississippi over the next three years.

Futuristic Concepts in Green Technology are Getting Attention

LA 161170.FI.0923.crazy-green01.FO.jpg

Frederic Scheer, Cereplast CEO,  hopes to use an algae byproduct to make utensils and other items.

Clean-tech ideas that have received government funding include using bacteria to make a gasoline-type fuel. Solar proposals seeking funding include sending collectors into space and beaming the sun power back to Earth.

Glowing Green Jellyfish Goo Could Power Medical Devices


Will we have jellyfish power soon?

Thanks to more acidic oceans, jellyfish populations seem to be flourishing. While they aren’t exactly edible for humans, they might be useful for powering nanodevices. Swedish researcher have been turning thousands of Aequorea victoria, a common North American jellyfish species, into liquid and extracting a green fluorescent protein (GFP) that makes the animals glow in the dark to see if it can also help create a biofuel cell that will generate small amounts of energy — enough to power microscopic nanodevices.

Growing Number of Homeowners in U.S. Complain Noise from Wind Turbines Making Life Unbearable

wind turbines

The industrial whoosh-and-whoop of the 123-foot blades is making life unbearable for some.

Like nearly all of the residents on this island in Penobscot Bay, Art Lindgren and his wife, Cheryl, celebrated the arrival of three giant wind turbines late last year. That was before they were turned on. “In the first 10 minutes, our jaws dropped to the ground,” Mr. Lindgren said. “Nobody in the area could believe it. They were so loud.”

Dog Poop Powers Lights In City Park

poo power
Conceptual artist Matthew Mazzotta has created a street lamp that uses
methane gas from feces collected at a dog park in Cambridge, Mass.
Environmentalists are going gaga for a street lamp in Cambridge, Mass., that is powered by dog poop.

The lamp, a shining example of how humans can make use of an underutilized and perpetually renewable energy source — feces — is the brainchild of Matthew Mazzotta, a conceptual artist who studied at the nearby Massachusetts Institute of Technology (MIT) who wanted to give back to the community…


Next Big Power Source? Pulling Electricity Out of Thin Air

lightning storm

“Hygroelectricity,” meaning “humid electricity” could be the next big power source.

We’re already making great strides at pulling electricity from the motion of the air and from the photons that stream through it, but what about pulling electric charges right out of the air itself? Researchers have solved a mystery about how electricity forms in the atmosphere, and in doing so may have found a way to pull electricity right out of the air.

Urine Could Hold The Key To Low Cost Energy, Say Scientists

urine for sale

Finding new uses for urine.

Urine could hold the secret to low cost energy, university boffins have revealed.

Researchers have developed a system to test whether it can be used in fuel cells as an alternative to flammable hydrogen or toxic methanol.

The work at Heriot-Watt University, Edinburgh, concentrates on urea, or carbamide, a mass-manufactured fertiliser and major component in human and animal urine.

The new Carbamide Power System could offer a non-toxic, low-cost, easily transportable alternative, academics said…

World’s Largest Hydrogen Fuel Cell Heads To Ohio

Fuel Cell a Go Go
We have talked about hydrogen fuel cells before around here. The ones we are familiar with are usually small and can barely produce enough power to charge a smartphone. The world’s largest hydrogen fuel cell is shipping to Ohio for its 5-year trial run.
The massive fuel cell is mounted inside a semi trailer and produces enough juice to run 500 homes…
