Algae and photosynthetic bacteria could also be exploited to generate electricity, besides jellyfish. University of Cambridge researchers let by Adrian Fisher and Paolo Bombelli study how they could use the two fore-mentioned to actually generate usable energy.

Researchers at Clemson University have a new mobile biofuels processing plant that will help do new research on new biomass feedstocks, like algae and fungio, while spreading the word of what biodiesel can do.
This press release from the school says its $125,000 piece of equipment from Piedmont Biofuels in North Carolina will provide the research platform and take the demonstration to the public:
“We had our initial successful run last week using waste algal and sunflower oils from Martek Biosciences in Kingstree and then used the biofuel to cycle back to a generator to achieve net-zero production,” [biosystems engineer Terry Walker said].
The plant is being developed to convert waste oils to high-grade biodiesel that can be used in many vehicles. The biodiesel is expected to cost less than regular diesel fuel, has a lower “carbon footprint” or environmental impact and can form the basis for a new industry in the state.
Walker said support for the purchase came from many sources, including Clemson Public Service Activities; the College of Agriculture, Forestry and Life Sciences and others at Clemson; Piedmont Biofuels in Pittsboro, N.C.; and SunStor Inc. in Greer.
The school will be showing off the new mobile facility at the annual biomass meeting this fall at the Pee Dee Research and Education Center on October 7th.

Recently, Zackary Chiragwandi at Chalmers University of Technology in Gothenburg, Sweden, and his colleagues have developed a solar cell based on a green fluorescent protein (GFP) from the jellyfish Aequorea victoria.

As I walked outside this morning, I noticed something— a chill in the air! I live in Colorado, where the nights get cooler long before the days do. This is the time where it's common to see people walking around with shorts and sweaters in the morning (gotta be prepared).
The sight of my breath was a reminder that soon I'll be running my heater again and will want to run it as little as possible while staying comfortable. If that sounds like your plan, consider scheduling a home energy assessment. Also known as an energy audit, an energy assessment shows you where your home is losing energy and how to make it as efficient as possible.
You can perform a simple energy assessment yourself, or hire a professional to provide a more thorough assessment.
A professional auditor uses a variety of techniques and equipment to determine the energy efficiency of your home, using equipment such as blower doors, which measure the extent of leaks in the building, and infrared cameras, which reveal hard-to-detect areas of air infiltration and missing insulation. At the end of the assessment, you'll know exactly what to do to make your home energy efficient, stay warmer this winter, and spend less money on utility bills.
Many utility companies provide this service for a reasonable fee, and some give discounts for low-income and elderly homeowners. This is one service that can pay you back in energy savings in the short or long term.
