Airships- greener ,cheaper -an opportunity ?

Massive algae-powered airship moves to NASA Ames Research Center 1

In California, NASA has entered into a three year lease agreement with E Green Technologies to to bring the world's largest airship to NASA Research Park at NASA Ames Research Center, Moffett Field.

The massive 235-foot long/65-foot diameter lighter-than-air vehicle is designed to fly on algae-based bio-fuel at speeds up to 74 mph, at altitudes up to 20,000 feet

How long will it take to go to green gas ? Response

What I told Scientific American in response to Shell's "What shall we do?"
Survey (and some ridiculously negative commenters)

This a copy of the reply I posted in "comments" section to ad posing as a survey in Scientific American's website.

Here's a link to that answer, from there you can browse some of the others if it interests you.

Sometimes I wonder if they put something in the executive water coolers in most major corporations that makes them incapable of seeing any innovation as being worthwhile. Naysayers who claim it will take 100 years to transition to new energy sources are either delusional or dissembling or just insist on ignoring the facts.
Fact 1. The claims that the main obstacle to using algae and algae oil as a source for "new energy" is the extraction of the algae from the water and the extraction of the oil from the water/algae is nonsense. It has been solved at least twice in the last couple of years. Once by AlgaeVenture Systems (the Ohio Univ. spinoff) that dredges and concentrates algae using a wicking system to partially dry it (remaining drying does take energy, but that can be concentrated solar directly as heat or converted to electric and back to heat) but from there extraction is as simple as pressing mustard seed or any other oil seed for that matter. (Please note that this also overcomes the Food vs Fuel trumped up debate because the "left over" algae after extraction IS FOOD, for animals or humans). The second solution, thought first to be proposed and proven, is from OriginOil, which is lysing the cells via ultrasonic disruption, which bursts not only the cell membranes but also the vacuole membranes which store oils within the cells. This is a "wet" process, separation is natural gravity, but speeded to less than an hour by Electro Coagulation (as Colorado Linings calls it in their process), but is the same system my company has been proposing for 4 years based on old sewage processing methods from the early half of the 20th Century.
Fact 2. Assuming you had a very large number of containers to put it in, but let us consider as an example a moderately slow growing algae that only replicates its biomass a single time each day (some reproduce every 4 hours, or 6 times a day, which is 2x2x2x2x2x2 [=64 times original biomass], yes, in a SINGLE day). But remember, just calculating 1 duplication of biomass per day, assuming ideal temp. and plenty of light, and adequate basic nutrients. On day 2 we have twice what we started with, which if it were 1 kilogram, by the 21th day we would have 1,000 Metric Tons of biomass (ignoring for the moment what percentage may be extracted as oil, since you'll soon see it doesn't matter). By the 90th day, our colony of algae will weigh MORE THAN THE PLANET EARTH. 
100 years is complete BULLSHIT! We could produce enough algae oil to replace all petroleum in 100 days! DO THE MATH YOURSELF!

Earth resource use

Report: Humanity 'pushing' plant resources
GREENBELT, Md. (UPI) -- Humanity is pushing Earth's plant resources harder as population continues to grow and countries develop modern economies, a NASA report says.

A NASA research group says an increasing amount of Earth's total annual land plant production is being consumed, mainly for food but also for paper, clothing, livestock feed, firewood, biofuels and other uses, ScienceDaily.com reported Thursday.

From 1995 to 2005, human consumption of land plants rose from 20 percent to 25 percent of the total plant production of each year, Marc Imhoff at NASA's Goddard Space Flight Center in Greenbelt, Md., said.

Both total global consumption and per capita consumption are on the increase, the report says.

"The question is, 'How hard are we pushing the land?'" Imhoff said. "People are wary about that percentage creeping up. Most people consider that a high number, although we're still doing research."

The research does not predict a "doomsday" scenario, he said, but does point to some future likelihoods if current population and consumption trends hold.

"What we're realizing is the biosphere doesn't care whether you have a lot of people consuming a little or a few people consuming a lot," he said. "It's the total rate that matters.

"If, in future scenarios, it's going to go up to something like 50 percent, we're looking at a very high demand for land management to maximize productivity at all levels on the landscape and at the expense of all other uses, for example, carbon sequestration, habitat or water storage," he said. "We would be heading toward a place where the planet would be very carefully managed, from end to end."

solar observatory -view the energy source

Solar image library available online
PARIS (UPI) -- The European Space Agency says its entire library of images from its solar observation programs is available online, allowing Internet users to explore the sun.

Using a software viewer called JHelioviewer, available for download, and images from the Solar and Heliospheric Observatory, users can create their own movies of the sun, color and adjust images as they wish, and track features on the sun, an ESA release said Tuesday.

"We wanted to make it easy to view solar images from different observatories and instruments, and to make it easy to make movies," Daniel Muller, ESA Deputy Project Scientist, said. "Before, it took hours to combine images from different telescopes to make a movie of the sun for a given period."

"With JHelioviewer, everyone can do this in minutes. This is an interactive visual archive of the entire SOHO mission," he said.

More than a million images from SOHO can already be accessed, and new images from NASA's Solar Dynamics Observatory are being added every day, the ESA said.

The Web site Helioviewer.org, a Web-based image browser, complements the downloadable JHelioviewer.

"The goal of JHelioviewer, and the Helioviewer Project as a whole, is to offer intuitive interfaces to large datasets from many different sources. In effect, it is a virtual observatory," Muller said.

Algae waste water treatment to green energy ideas

Algae for Wastewater Treatment & Biofuels
Algae grow best off waste streams - agricultural, animal, or human. All over the world, municipalities and utilities spend enormous sums to treat wastewater and sewage and remove them of pollutants and impurities. Some of the pollutants in the wastewater and sewage are nutrients on which algae thrive. Yet another fact is that the algae that grow in human-sewage tend to have a lot of oil. Combine the above three facts and you get a rather interesting solution: Grow algae in sewage/wastewater to clean the medium while producing biofuels!
Algae, especially microalgae can bio-filter nutrient-laden, CO2-laden and low-oxygen water and turn it into oxygen-rich, CO2-low water as it flows back into the ecosystem, while simultaneously producing oil.
One of the key advantages is that, apart from the fact that expensive reactor systems are not required, unlike other algal-biofuel technologies this approach relies on "wild algae" - i.e., algae that naturally colonize sewage ponds already.
The advantage of algae-based waste water treatment is the end-product in the process - algae biomass, which can be used as a biofuel feedstock.
Given the right conditions, algae can double its volume overnight. Microalgae are the earth's most productive plants - 10 to 15 times more prolific in biomass than the fastest growing land plant exploited for biofuel production. While soy produces some 50 gallons of oil per acre per year; canola, 150 gallons; and palm, 650 gallons, algae can produce up to 15,000 gallons per acre per year. In addition, up to 50 percent of biomass for some microalgae is comprised of oil, whereas oil-palm trees - currently the most efficient large-scale source of feedstock oil to make biofuels - yield approximately 20 percent of their weight in oil.

The following table gives some typical yields in US gallons of biodiesel per acre Plant Yield of Biodiesel(gallons per acre)
 

Algae 5000 and higher

Oil from microalgae can easily be converted to biofuels such as biodiesel through the same technology used with oil from oil seeds which is currently used to convert vegetable oil to biodiesel (transesterification is the main conversion process). In addition, it is possible to hydro-treat the algae oil to produce other fuels such as JP-8 and other jet fuels.
