The Engine's Out! On Purpose!

EcoGeek is willing to try a lot of weird stuff to cut back on use of various resources. But it's with mixed glee that we announce this next particular advancement--mixed because it sounds like a great idea, but EcoGeek's going to wait to see it work a few times before participating: planes in New Zealand will now be cutting the engine before landing because, hey, who needs to accelerate when you've got gravity on your side?

OK, so the engines won't be totally cut--they'll be idling--but the point is that the buy levitra online australia planes will be saving on energy and cutting back on emissions a bit. When you think about all the commercial flights in and out of any given airport on any given day, any small saving on each flight could really stack up.

According to The Age, it sounds like the most difficult part is actually changing the amount of time and space between planes landing, rather than any mechanical adjustments to the fuel-light landing.


MixAlco: Cows Help Make BioFuels

At first glance, cows don't seem to be all that technologically advanced. However, they've got a trick up their, er, sleeve, that so far we humans haven't been able to duplicate.

Cows can turn cellulose (grasses) into sugars without needing a mutli-million dollar facility. If we had that power, our bio-fuel problems would be over, and corn-based bio-fuel would no longer be needed.

 Professor Mark Holtzapple of Texas A&M analyzed how a cow’s stomach(s) work to levitra en gel help design a process for making ethanol and many other alcohols from cellulosic materials. The result is the MixAlco process where almost any organic material can be converted to high energy biofuels.

This process can be used to convert waste materials to provide almost all of our automotive energy needs. He specifically shows how much waste we make – agricultural, municipal and sewage and how much ethanol can be derived from each of drug cialis these feedstocks. 

By using these waste streams as the fuel feed stock, the MixAlco process can provide much of our fuel needs without displacing valuable crop lands or using high energy crops such as corn. 

Because they have low capital costs and relatively simple operation, the MixAlco pretreatment and fermentation steps may be carried out on-location at sewage treatment plants or municipal landfills. Several studies have shown that MixAlco is capable of economically converting both dairy manure and chipped yard waste into alcohol.

We need to push for cellulosic ethanol as an alternative to both gasoline and to corn based ethanol.  Just today the viagra and canadian price of corn hit a ten year high of $4.31 per bushel, roughly twice what it cost last year.  This is creating hunger and economic chaos in Central America where corn is where to get cialis in canada a staple of their diet.  

Professor Mark Holtzapple, holder of many patents on the MixAlco process makes a great presentation at Texas A&M for their distinguished lecture series.

Sydney's Earth Hour a Success


At 7:30PM last Saturday, Sydney turned off it's lights.  Referred to canada drugstores americans viagra border as Earth Hour, it is the beginning of a year of activities in which the World Wildlife Fund and The Sydney Morning Herald hopes to reduce Sydney's greenhouse gas emissions by 5%.   More than 65,000 houses and 2000 businesses participated in the event, including notable sites like the Opera House and the Sydney Harbour Bridge. During the hour, electricity use for Sydney dropped over 10% preventing over 24 tons of carbon dioxide release.

Their website housed information on special activities to do in celebration of the lights out period; the offers ranged from stargazing to speed dating by candlelight.  However, the organizers main focus was to get others involved in solving the climate crisis and to show them that small, everyday actions can have an impact. 

Other than promoting voluntary individual involvement, they worked with government and businesses to get building and office lights turned off.  They noted that efficiencies and reduced light use in Australia's commercial sector alone "could reduce lighting emissions by 70-80%".

For more information check out the cheap cialis india Earth Hour website. They're also offering "the world’s only useful screensaver", which encourages users to turn off their computer and counts kW usage as well.


Ocean Safe Biodegradable Plastic

Throwing plastic overboard might be an option for ships in the future. At The University of Southern Mississippi, scientists have been studying and creating plastics that degrade in saltwater into nontoxic and natural byproducts within as little as 20 days. 

Ships are currently required by maritime law to be store plastic waste onboard until they can be emptied at port. Unfortunately, not all plastic waste is properly disposed at port and it ends up in the oceans. By creating different types of biodegradable plastics, the scientists hope to replace all varieties of plastics used on cargo ships and cialis online best eliminate the problem of plastic ocean waste. 

Ironically, dumping plastic in the oceans will need to be legalized before their product can be legally used. They have some time however since the biodegradable plastics are still in development, as tests need to be done to see if they will degrade in different ocean environments.

Shrink-Wrapped Trash

The latest innovation in waste disposal is not in converting it into fuel or electricity, but in how the waste is contained and transported. Currently, steel containers of order usa viagra online trash are delivered to landfills via gas guzzling big rigs where sitting waste causes problems such as groundwater pollution. TransLoad America hopes to remedy these problems with a German shrink-wrapping technology.

The technology "compresses tons of garbage into dense cylindrical bales and seals them hermetically in several layers of plastic film," after which TransLoad plans to transport them to landfills through the use of rail lines. This system provides benefits to the environment and reduces cost. Groundwater pollution is prevented by the use of "impermeable plastic" wrap and shipping by rail cuts down on fuel use and emissions. Only 22 tons of waste can be transported through traditional trucks, while a boxcar of bales can hold 100 tons. TransLoad already custom designed and ordered 1,200 rail cars to make the process even more efficient.

With a launch date of early 2008, TransLoad hopes to change the link for you get levitra in canada way trash is handled. Aiming even higher, they hope to use future technology to change its landfills into producers of "biofuels, electricity, [and] heat" with its bales as the source.
