Our company invented already a formula reducing CO2 emmisions by 80% in diesel-use engines.Also reduces
the manufacturing cost of diesel. Al of above are without changing any engine, filling station etc.It
doesn't need winter and summer formules.We will determine shortly if it has a peak freezing point or do not have any, as it was kept in a freezer for 9 months without any sign of freezing.It will be shortly in the media.

We all need to fly less fullstop , in 1967 a roundtrip to and from
Sydney from the UK cost 800 pounds sterling , more than a years
wages, now it costs 500 pounds , 2 weeks wages ! its totally
un-sustainable .
I always thought that Richard Branson was a good guy , in
the end hes just like all the rest , the mearest wiff of a quick profit
and will be ready to trash the planet !
I suppose todays news of the discovery of another earth like
planet comes at a good time , we may need it ! or more likely our
corparate pals have already bought it ! even so at 800,000 years
travel thats one **** of a lot of biofuel !

Frankfurt/Main Airport, the biggest one in Germany and one of the biggest in Europe, has been towing planes to and from runways for donkey's years without any serious problems. The main objective is noise reduction, though any improvement in fuel economy is of course welcome.

@ andrichrose -

it may no longer be appropriate to fly when alternatives such as high-speed trains (or the telephone, sic) are available. Flying from e.g. London to Paris makes little sense, because of the time lost in ground transportation to and from the airports plus check-in, security checks, frequent delays, risk of lost baggage etc. Paris and Frankfurt will soon be linked by high-speed rail routes, as well.

However, for long-distance travel (>1000km), a flight in which most seats are actually occupied - as they tend to be on e.g. the transatlantic routes - actually uses less fuel than you might think. For the A380, a number of just 3L/100 passenger-kms is projected, about the same as a grand tourer car driving briskly on the autobahn with 4 persons and baggage on board.

Boeing's dreamliner is supposed to come in even lower, especially if you consider that it is designed to support a gradual transition away from rigid hub-and-spokes operations.

environmental partnership, which includes an order for 15 787-9 Dreamliners, marking the largest 787 order to date for Europe.

The environmental partnership includes a joint biofuel demonstration aimed at developing sustainable fuel sources suitable for commercial jet engines and the aviation industry. The demonstration, scheduled for 2008 using a Virgin Atlantic Boeing 747-400, is being worked on with GE Aviation and Virgin Fuels. Further details will be announced later this year.

Currently, Sasol provides a semi-synthetic jet aviation fuel (a 50:50 blend of petroleum-based fuel and a Gas-to-Liquids (GTL) aviation fuel), with approval for a 100% synthetic FT blend expected this year. The US military is exploring the use of coal-to-liquids (CTL) or biomass-to-liquids (BTL) Fischer Tropsch blends as a common fuel. (Earlier post.)

On the aviation biofuels front, North Carolina State University engineers are developing a technology to turn virtually any lipidic compound—e.g., vegetable oils, oils from animal fat and oils from algae—into aviation fuel or other high-value fuels. (Earlier post.)

In addition, Boeing and Virgin Atlantic are working together on reducing fuel burn and cutting aircraft emissions on the ground by exploring alternatives to traditional aircraft operations at airports.

For example, Boeing and Virgin Atlantic are partnering on trials of towing airplanes to starting grids, areas close to the active runway to start engines preflight, with a goal of reducing fuel consumption and carbon emissions by up to 50%, as well as limiting community noise. Trials conducted thus far at London’s Heathrow and Gatwick Airports and San Francisco International Airport have produced positive results, and work continues to develop alternative operational procedures at the world’s busiest airports.

The 787 Dreamliner uses 20% less fuel per passenger than similarly sized airplanes. The 787 will produce lower carbon emissions and offer quieter takeoffs and landings.

The jet order, worth approximately $2.8 billion at list prices, also includes options for an additional eight 787-9s and purchase rights for an additional 20 787s.

Since the 787 launch in April 2004, 44 customers worldwide have logged 544 orders worth more than $75 billion at current list prices, making the Dreamliner the most successful commercial airplane launch in history.

Comments
It will be interesting to see how close the 787 will be able to get to the A380 on per seat fuel efficiency, not to mention whether Boeings claims that the 747-8 will be more efficient than the 380, per seat, will be true or not. Seems like the idea of towing the planes to a staging point away from the gate would increase the chances of having a serious flight delay with the passengers stuck out on the tarmac instead of being able to de-plane. With the new drive for customers bill of rights, this might not fly.

Dear

I just discover almost one year a go you can abstract.
cellulose from trees witout cutting a tree.
I was jail in kenya because they wanted to take my idea by force,then i went back to my home town were the small investor was so greedy ,he managed to take my secret from my wife,then I was put in jail for 49 days in abu-dhabi uae because, they did not have much information in the patent,were I knew laws they dont protect patent,I were told that I wanted to cheat but the judge refused all the evidence,however they did not kill my idea and I am putting up an academic to train 3500 students in the sultanate of Oman,were we will grow plants in the middel of desert to produce cellulose raw materials to make ethanol, 5 years from now we can be one of the 10 top producer of bio-fuel from now, my message to you all
dont give up,even if you have to be jail due to the idea, stick to your ideas God is there for you.
as long as you are a live dont give up your idea.
I made mistakes and learn from lots of mistakes,in the end,the key is willpower.

I really don't understand that attitude, Andri. Are you saying that people should never see the world? Never leave their homes?

I am mystified by this hair-shirt attitude I see from so many environmentalists.

How do we swerve from bio-jetfuel to trashing the people who make it possible? Both these companies should be supported in making efforts to address the jetfuel issue.

Of course as high speed mass transit improves as part of the transition to sustainable energy - we'll see a lowering of air miles. Who wouldn't want to travel by high speed rail compared to the coffin-like sardine can effect of airline seating configurations?

There are developments inDME in CHina today!
We see great potential for DME as a clean alternative fuel . The present diesel oil is a major source of air pollution from diesel engine of trucks and busses in large city like Tokyo. The potential market of diesel oil substitute is larger than LPG. DME is one of ideal fuel for diesel engine. DME vehicles were demonstratively manufactured in Japan, China and Korea and their driving test already started. Practical durability fleet test of a DME truck is under going in Japan.

We are pleased to organise a conference on China taking the lead in the DME market in production from coal and Japan and Korea activities.

If you would like to know more on COAL to Syngas to DME developments, join us at upcoming North Asia DME / Methanol conference in Beijing, 27-28 June 2007, St Regis Hotel. The conference covers key areas which include:

DME productivity can be much higher especially if
country energy policies makes an effort comparable to
that invested in increasing supply.
By:
National Development Reform Commission NDRC
Ministry of Energy for Mongolia

Production of DME/ Methanol through biomass
gasification could potentially be commercialized
By:
Shandong University completed Pilot plant in Jinan and
will be sharing their experience.

Advances in conversion technologies are readily
available and offer exciting potential of DME as a
chemical feedstock
By: Kogas, Lurgi and Haldor Topsoe

Available project finance supports the investments
that DME/ Methanol can play a large energy supply role
