Amazing Algae Powered Lamp Converts CO2 to Light
This amazing lamp is powered by algae. Just add CO2 by breathing into it, and the algae will handle the rest. Scientists have discovered a way to extract electrical energy from the algae, and it can power the lamp. This is a cool technology that could provide provide an interesting way to light your home. “In 2010, scientists from Yansei and Stanford University pioneered a technique by where 30-nanometre wide gold electrodes were inserted into the photosynthesising organs – chloroplasts – of algal cells, thus managing to draw a small electrical current from algae during photosynthesis. As advances in nanotechnology lead to increasingly energy efficient products, plant life such as algae will become attractive sources for tapping energy. via:
Fossil fuels are way more expensive than you think | Dana Nuccitelli | Environment
A new paper published in Climatic Change estimates that when we account for the pollution costs associated with our energy sources, gasoline costs an extra $3.80 per gallon, diesel an additional $4.80 per gallon, coal a further 24 cents per kilowatt-hour, and natural gas another 11 cents per kilowatt-hour that we don’t see in our fuel or energy bills. The study was done by Drew Shindell, formerly of Nasa, now professor of climate sciences at Duke University, and Chair of the Scientific Advisory Panel to the Climate and Clean Air Coalition. Shindell recently published research noting that aerosols and ozone have a bigger effect on the climate in the northern hemisphere, where humans produce more of those pollutants. That research led Shindell to question current estimates of the true costs of our energy sources. But Shindell also estimates that carbon emissions are relatively cheap compared to other fossil fuel air pollutants. Electric Cars Cheaper than Gasoline Powered
THE POWER OF COMPOST: Can You Power & Heat Your Off Grid Home With Compost?
“Compost (/) is organic matter that has been decomposed and recycled as a fertilizer and soil amendment.” That’s how Wikipedia defines it. We know that when biomass decomposes a biproduct of that decomposition is heat. Now… If you could capture that heat, it can be used for multiple purposes if stored and used efficiently. “Biomass is biological material derived from living, or recently living organisms” “…Can We Charge Batteries With Compost? Mad River Valley, Vermont’s Gaelan Brown Speaks on “Compost Power” You can also heat your water with compost Technically this is a very simple design that just about anyone can build themselves. Compost is MUCH cleaner than coal power, and doesn;t pollute the atmosphere. If you have a compost spill, guess what happens? Plants grow!
Blog » Clarity on the true cost of electricity
The question of electricity cost is tricky. Most of us know oil prices go up and down – and are currently at record highs – which in turn affects the power price. And we know that not only to the costs of importing such fuels change constantly, they also – unlike renewables – produce carbon, which has to be paid for. But while more and more people are saying onshore wind energy is at “competitive” price levels, others still insist that renewables are expensive and impractical. In order to clear up the issue , EWEA has developed an online tool that instantly calculates electricity costs, including any fuel and carbon risks, for five different technologies – gas, coal, nuclear, onshore and offshore wind. “Using the tool, you can calculate levelised costs – that means, the average cost of the electricity over the lifetime of the plant – for the main technologies,” explains EWEA’s Athanasia Arapogianni, who helped develop the tool.
Constructing a Medium Sized Biogas Plant Using Kitchen Waste
Long back I have posted an instructable on how to construct prototype of a Biogas plant, using 50 liter capacity tank as digester, which you can see here : That was my first instructable and people are still commenting and asking me for guidance on Biogas plants for home use and for demonstration at schools & colleges. I have replied and mailed guidelines to almost all of the queries and I hope that helped them in their quest for building their Biogas plant. As you can see in the last step of this instructable, I was invited by Hajee Karutha Rowther Howdia College, Uthamapalayam, Theni District in Tamil Nadu, India, to present a keynote address on Biogas and Panchagavya (an organic product made from produce from cow).

biochar.biochar-overview.cfml
Biochar is defined simply as charcoal that is used for agricultural purposes. It it created using a pyrolysis process, heating biomass in a low oxygen environment. Once the pyrolysis reaction has begun, it is self-sustaining, requiring no outside energy input. Byproducts of the process include syngas (H2 + CO), minor quantities of methane (CH4), tars, organic acids and excess heat. Once it is produced, biochar is spread on agricultural fields and incorporated into the top layer of soil. Studies have indicated that the carbon in biochar remains stable for millenia, providing a simple, sustainable means to sequester historic carbon emissions that is technologically feasible in developed or developing countries alike. When biochar is created from biomass, approximately 50% of the carbon that the plants absorbed as CO2 from the atmosphere is ? Effect of Biochar on Soil Fertility Below are a series of photos demonstrating the effect of biochar on soil fertility.
How do the products work? - SolTech Energy
SolTech has a patented solution to integrate a solar energy system with a roof. This means that when you need to lay a new roof, you also get a solar energy system into the bargain. Instead of laying a standard roof that uses materials such as concrete tiles, we lay our own specially-developed glass roof tiles. SolTech Sigma is the name of the waterborne solution that channels heat down from the roof to the building’s heating system by means of pipes that are connected to the accumulator tank, which acts as the solar capturing device. SolTech Power is the name of the solution that generates electricity.

The days of drilling into the ground in the search for fuel may be numbered, because if Daniel Nocera has his way, it'll just be a matter of looking for sunny skies. Nocera, the Patterson Rockwood Professor of Energy at Harvard University, and Pamela Silver, the Elliott T. and Onie H. Adams Professor of Biochemistry and Systems Biology at Harvard Medical School, have co-created a system that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels. The paper, whose lead authors include post-doctoral fellow Chong Liu and graduate student Brendan Colón, is described in a June 3 paper published in Science. "This is a true artificial photosynthesis system," Nocera said. While the study shows the system can be used to generate usable fuels, its potential doesn't end there, said Silver, who is also a Founding Core Member of the Wyss Institute at Harvard University. "This is the genius of Dan," Silver said.
