DOE Releases Feasability Study for Illinois Coal to Liquid Plant
Via: Auto Blog Green
May 22nd 2007
The Department of Energy's National Energy Technology Laboratory has completed a feasibility study for a proposed Coal to Liquid fuel production facility in Illinois. The proposal would include a plant that would convert coal into fuel along with electrical power that would go back into the grid. The input would be high-sulfur bituminous coal which would be gasified and the gas converted to liquids by the Fischer-Tropsch method. The output would include diesel. This diesel will need to additional additives before it could be used. The other output products will be be naptha, which can be used as a chemical feedstock.
The study projected the $3.65 billion plant would have a 20% annual return on investment...

Molecular visualization of the bioconversion process
The tools available for the hunt for renewable energy are very 21st Century. New tools include robotics, mass spectrometers, laser imagers, and data collection and analysis devices. As a result, communications can be digital and more visual than ever before, speeding questions and understanding at warp speed around the globe.
The Society of Industrial Microbiology convened their 29th Symposium on Biotechnology for Fuels and Chemicals in Denver recently which was hosted by the federally-financed National Renewable Energy Laboratory (NREL). One of the highlights of the symposium was a tour that included visits to its biochemical and thermochemical labs and pilot plants for converting an array of feedstock into sugars and ethanol.
One stop was in a research area where high tech imaging devices are employed to analyze cell and molecular structures involved in the bioconversion process. Data collected from such imaging devices can be used to build accurate models and animations to aid understanding. This post from Bioconversion blog provides more details on these high-tech imaging devices and the impact they will have...

Hydro Power Invention - No Reservoirs Required
April 11th, 2007 - Alternative Energy Info
A new hydro power technology is being developed by Sarfraz Ahmad Khan of Pakistan. In theory these hydro plants would not require a reservoir and would have a minimal impact on the environment. They could be run side-by-side in rows and would be much cheaper to build, operate and maintain. Sarfraz has high hopes that his ideas could revolutionize hydro power in his country and across the globe. He is currently seeking expert confirmation of his ideas; this article provides a brief summary of his ideas along with some of the 3D images he has created. You can help him by leaving your comments at the bottom of the page, or by joining the discussion that inspired this article.

Vertical Axis Windmill Invention
April 26th, 2007 - Alternative Energy Info
Toronto Inventor Tom J. Gilmour recently published his conceptual designs for what he is calling Tom’s Whirligig. Patent applications have been made, and Tom hopes to reserve all rights and worldwide patents for his design. Tom believes his windmill plans to be the most complex ever devised. While he is not yet sure of the workability of this concept, he is optimistic about its feasibility and hopes to soon find the time to build a working model.
This new design is based around a continuously rotating carousel, which houses eight symmetrical airfoils. The entire carousel is mounted on a fixed vertical shaft. A top mounted central weather vane keeps the cam shaft pointed at the wind.

Fertilising the Oceans - Thin Soup and a Thin Story
2 May 2007 @ Real Climate
A firm called planktos.com is getting a lot of attention for their bid to create a carbon offset product based on fertilizing the ocean.
In certain parts of the ocean, surface waters already contain most of the ingredients for a plankton bloom; all they lack is trace amounts of iron. For each 1 atom of iron added in such a place, phytoplankton take up 50,000 atoms of carbon. What could be better?
Phytoplankton biomass does not last forever, any more than tree biomass does. The trick therefore is to get the carbon to sink out of the surface ocean into the depths, generally in the forms of snot and poop. Once it reaches a depth of a kilometer or so, it can decompose to CO2 again but the water will be isolated from the atmosphere for decades, maybe centuries.
Sounds like a great idea? May be yes, may be not...read the detailed post here @ Real Climate to know more

Higher Air Conditioner (AC) Efficiency Using Solar Power
You may have probably heard of Solar Air Conditioner. It can produce cooling effect by absorbing heat from Sunlight. Normally, these types of ACs are absorption type refrigeration systems using Ammonia cycle, salt and vapor pressure stuff. But these are still limited to research labs with few commercial applications.
In this post the author talks about using electricity (from solar) to get some extra points of efficiency from your existing AC.

New Enzyme Discovery Could Make Ethanol Cheaper
A new plant enzyme has been discovered by Cornell University researchers, which could make the production of cellulosic ethanol less expensive.
A critical step in producing cellulosic ethanol involves breaking down a plant's cell wall material and fermenting the sugars that are released. This enzyme, according to scientists, could potentially allow plant materials to be broken down more efficiently.
The new class of plant enzymes has a structure similar to the microbial enzymes called "cellulases" which are used to digest the cellulose in grasses and similar plants.
While the scientists found the new enzyme in a tomato plant, they are confident that such proteins are present in other plant species that could be used for biofuel production.

Ethanol vehicles pose a significant risk to human health
Medical Research News, 20-Apr-2007
Ethanol is widely touted as an eco-friendly, clean-burning fuel. But if every vehicle in the United States ran on fuel made primarily from ethanol instead of pure gasoline, the number of respiratory-related deaths and hospitalizations would likely increase, according to a new study by Stanford University atmospheric scientist Mark Z. Jacobson. His findings are published in the April 18 online edition of the journal Environmental Science & Technology (ES&T).

Chemists at UCLA Design Crystals for Applications in Clean Energy
13 Apr 2007
Chemists at UCLA have designed new organic structures for the storage of voluminous amounts of gases for use in alternative energy technologies.
The research, to be published on April 13 in the journal Science, demonstrates how the design principles of reticular chemistry have been used to create three-dimensional covalent organic frameworks, which have high thermal stability, high surface areas and extremely low densities.
The covalent organic frameworks, or COFs (pronounced "coffs"), one of these new classes of materials, are the first crystalline porous organic networks...Some of the biggest energy & environment challenges have been finding ways to store hydrogen for use as a fuel, to use methane as an alternative fuel, and to capture and store carbon dioxide from power plant smokestacks. The research team believes COFs are uniquely suited for all these applications because of their functional flexibility and their extremely light weight and high porosity.

Animal Fats into Jet Fuel
March 19, 2007
RALEIGH - Airlines could soon be looking to acquire chicken grease and hog lard to convert into jet fuel.
A team of NCSU scientists and engineers says it has developed a biofuels technology capable of converting animal fats - including lipids from dead chickens, hogs and cattle - into fuel for airliners and fighter jets.
The technology is "100 percent green," as no petroleum-derived products are added to the process. It can also be used to make additives for cold-weather biodiesel fuels and holds the potential to fuel automobiles that currently run on gasoline.

Genetic engineering industry hopes to save the world
March 23, 2007, By Markus Städeli - Check Biotech
Greenpeace has recently sparked of the genetic engineering controversy in Europe once again. The environmental protection organization claims that a genetically modified maize made by Monsanto has caused liver and kidney damage to experimental animals.
Monsanto strongly contests these accusations.
However, opposition to this technology remains strong. On the other hand, the genetic engineering industry does now see an opportunity to permanently clean up its somewhat tarnished Image. It hopes that the bioethanol boom will help here.

Research could Make Fusion Energy Possible
March 10, 2007
Science Daily — A project by University of Wisconsin-Madison researchers has come one step closer to making fusion energy possible.
The research team, headed by electrical and computer engineering Professor David Anderson and research assistant John Canik, recently proved that the Helically Symmetric eXperiment (HSX), an odd-looking magnetic plasma chamber called a stellarator, can overcome a major barrier in plasma research, in which stellarators lose too much energy to reach the high temperatures needed for fusion.
