We know that there are attempt to produce and better the fuel from algae. Has any one tried to used algae cakes left after extraction for use in the biomass gasifiers to produce energy?...Is it efficient to do this instead of using the algae mass as feed for humans and animals?

Through extensive testing I've performed over the last 2 months, I've concluded that the method of Low Energy Voltaic Impulse(LEVI) destroys specific protein channels along the cell wall membrane, allowing for lipid bodies (and some cytoplasmic fluids) to be secreted by the cell. By pumping this device with 120 gallons of water I was able to produce 4.35 Liters of lipid bodies which converted to 4.1 Liters of diesel fuel via transesterification. To run down 2 D cell batteries, I needed to perform this test 82 times producing just over 90 gallons of diesel fuel, and the lowest cost fuel conversion price of $0.03

Enthusiastic researcher on cellulosic ethanol to drive the World.

have got an assignment to prepare biodiesel fromwaste cooking oil for my mini project, is there any methods for improving its properties ie how to reduce the carbon residue and improve other properties .can nano particles or addition of any similar chemicals can serve my purpose especially to reduce the carbon residue?

London-based product designer Oscar Diaz has designed Tube Toys, which range from a fire truck to a train to a tractor. The toys are packaged in tubes that hold the wheels, accessories and labels that are required to be assembled.

The only piece that is discarded after assembly is the paper label outside the tube, and all of the components are recyclable or made of recycled materials.

Snow Lizard has unveiled their AQUA TEK S case for iPhone 4 and 4S, the first that is battery-charged, waterproof and solar-powered for outdoor adventures.

This case isn't a thin, sleek case for keeping in your pocket, it's made for people who take their phones into more extreme situations and need a little more padding. The case is built from thick, dirt-resistant poly-carbonate with rubber grips and it is waterproof up to 20 feet. It features a built-in battery that can be recharged by the solar panel on the back of the phone. All of the phone's features and controls -- camera, volume, speakers and display -- are still accessible when using the case, meaning you can finally put the improved 4S camera to the test with some underwater photos.

Apple $ 1 billion data center in Maiden, North Carolina, will have a 20 MW solar installation, located on 100 acres which will supply 42 million kWh of renewable energy each year. Apple is also building a 5 MW fuel cell installation adjacent to the data center, which will be powered by 100% biogas and provide more than 40 million kWh of baseload renewable energy annually.

The facility has already earned the LEED Platinum certification. The data centre’s chilled water storage system is designed to improve chiller efficiency by transferring 10,400 kWh of electricity consumption from peak to off-peak hours every day. Outside air is funneled into the building at night and during cool-weather hours. Use of outside air and the water storage system allows the chillers to be turned off more than 75% of the time.

The data centre also boosts white cool-roof to reflect sun, high-efficiency LED lighting equipped with motion sensors, and power distributed at higher voltages to increase efficiency by reducing power loss.

ATC Solar Curve Bus Stop concept is being developed by Studio Mango for the city Noord-Brabant, Netherlands, which would allow inductive charging technology at existing bus stops, which will enable electric buses to recharge each time they stop to pick up passengers.

The concept calls for installation of 15.5 meters of solar panels on top of a bus stop’s roof, which would convert sunlight to solar power throughout the day. The curved roof would be sufficiently tilted down to enable wireless energy transfer to buses using inductive charging, which employs the use of an electromagnetic field to transfer energy.

There are issues with monocultures since they are not natural. Symbiotic communities are better in many ways. What are some communities of algae that would be beneficial? Say for Botryococcus or another high oil green algae. What would be the best kinds of cyanobacteria, diatoms, or purple bacteria for a botryococcus dominated community? I would like to know of different examples for the maximum production of each hydrogen, oil, and carbohydrates, as well as the best community for producing all of these compounds together as well as the natural release of these compounds. Also what cold climate species can coexist with B.B and take over when conditions are unfavorable to BB?

I am very sorry to have to write this but I must
the above vidio is of absolutely no use to me,
I see the wing of an airplane bouncing about in the sky, catching a glimpse of green fields with no description of what I am seeing.
I am very much into getting the world going in a good direction,
this kind of poor production should be kept in a box until higher quality can be produced,
please, this is serious affair, we need to do good work.

A new MIT study shows that, at least for the foreseeable future, proposals to capture carbon from the air are not realistic. Are you agree with this assertion?

Happened to read this paper "Biotransformations of carbon dioxide in photobioreactors"(http://www.mendeley.com/research/biotransformations-carbon-dioxide-photobioreactors/#), it's abstract says: Despite large amounts of CO2 that were sequestered during the cultivation, it is demonstrated that only a small fraction (about 3%) was effectively fixed as microalgae biomass, indicating the existence of other routes of CO2 conversion in the photobioreactor.
