Algae Algae Everywhere. So Let's Light it on FIRE!

I've been a little inundated by algae today. First I finished a chapter in Earth: The Sequel all about algae biodiesel, and then I ran across a profile of algae startup Solena at the viagra without prescription NYTimes. And THEN I got an email from Sam at GreenFuelsForecast about their summary of the History and amarragessansfrontieres.com Future of Algae Biofules. And just moments ago Katie from Earth2Tech emailed me their story on the Top 15 Aglae Startups!

Wow! Seems to where to order viagra online me like March 27th 2008 is algae's official tipping point!

The news, my friends, is good. Algae is the best plant out there for converting sunlight to energy. It's 100x better at creating usable energy per acre than corn is. And tons of levitra online shop new and old companies are trying different strains of algae and different ways of growing them not to mention using them to clean the flue gas coming out of power plants.

Algae, it turns out, eat NOx emissions without trouble, and, of course, grow much faster in higher concentrations of CO2. The only problems are sulfur dioxide, which can acidify the water (just like it does to rain) and kill the algae, and mercury, which can accumulate in the i use it generic cialis pill algae and make them dangerously toxic.

Welcome to the future, where single-celled plants eat our pollution and power our cars. Who'd a thunk...

 

US Army Turning Waste into Energy in Iraq

The US Army is shipping a couple of giant trash-powered generators to Iraq in order to, hopefully, decrease the amount of fuel that needs to how much does cialis cost be transported around the volatile region.

The generators separate food waste from solid waste like trash and plastic. The food is converted to ethanol in a bioreactor, while the solid waste is we recommend online cheap cialis converted to low-grade methane and propane. The innovation here is the ability to convert all trash, not food or plastic or paper, but all of http://www.pneumapaniagua.es/canadianpharmacy them combined in one unit to produce power. The device can eat about a ton of trash every day, while producing about 50 kilowatts of excess power.

I was a little surprised to hear how much trash was being generated by the Army, but it turns out that pretty much everything they eat and drink from is disposable. I suppose it's better to turn it into fuel than send it to some landfill in Iraq, but it makes me wonder whether this is the most intelligent way to only for you canadian pharmacy levitra prescription do things.

Solar Produces 1000x More Energy Per Acre than Soy BioDiesel

Lots of people are getting excited about all the various technologies for using biofuels of one sort or another as a replacement for fossil fuels, and they may present a short-term option. But looking at the various kinds of energy production that are possible gives some insight into the cialis 5 mg italia best directions to promote in terms of developing long-term efficient energy production.

A study cited on EV World makes a comparison between different crop- and direct-production methods of the best place levitra pharmacy generating energy in terms of miles per acre per year, with some eye-opening information.

At the bottom end of the scale is soybean biodiesel, which can provide only 2,400 miles per acre per year. Corn ethanol is more than six times as efficient, yielding 18,000 miles per acre per year. But because of the relatively slow rate of production from plant-based fuels, these options far fall below the productivity of directly produced energy.

The same acre can produce 10 times as much energy from wind as it can from corn ethanol, 180,000 miles per acre per year. But both corn ethanol and wind power pale in comparison with solar photovoltaic, which can produce more than 2 million miles worth of transport per acre per year.

This is not to completely dismiss biofuels out-of-hand. The cost of an acre's worth of solar PV arrays is canadian healthcare far more than 100 times more expensive than planting an acre of only here levitra pfizer 50 mg corn. Many biofuels can be produced on free levitra marginal lands that are ill-suited for solar. And cellulosic ethanol can even be produced from waste, effectively making it a zero land-use fuel. And presumably the comparisons are based on sites that are optimal for each mode of generation. A site that is highly suitable for harvesting wind energy may not be a good site for growing corn, and vice versa.

The infrastructure and the existing "car parc" (the entire fleet of all vehicles in the country) is also going to take decades to turn over to the point where a significant proportion of the vehicles on the road are electric vehicles. Both a mix of energy sources and regionally appropriate choices need to be part of a comprehensive energy plan. But this offers a useful comparison that suggests where the best allocation of resources should be focused in terms of long-range planning for our energy future.

New Plant to Produce 100 M Gallons of safe online viagra Ethanol from Waste

range fuels

Range Fuels has already begun building the country's first cellulosic ethanol plant in Georgia. The plant has a goal of producing 100 million gallons of ethanol per year using leftovers from Georgia's giant timber industry. Unfortunately, right now Range Fuels only has enough money to cheap tramadol free delivery build 20 million gallons per year of capacity. The money to do that came mostly from government grants.

But now Range has announced that they've raised another $100 M from Khosla Ventures and an unnamed energy company. The injection of funds will allow range to meet it's 100 million gallon per year goal, hopefully by 2009.

Range's technology gasifies the buy cheap viagra soft plant cellulose using a technique created to turn coal into liquid fuel. After the gasification, turning the wood chips into ethanol is fairly trivial. Unfortunately, the process is much more expensive than the processes that turn corn into biofuel.

But the expense of the process, it turns out, is less important once corn prices start skyrocketing due to increase demands both for food and ethanol. Wood chips on the other hand are pretty much free. This is how Range hopes to make up the difference in cost, hopefully scaling up to the point where their ethanol is actually cheaper than both corn ethanol and gasoline.

$100 M definitely won't hurt their attempts to achieve this goal.

18 Months Until Custom-Made, Oil-Pooping Bacteria

Craig Venter has his own scientific institute. He led the private effort to united healthcare levitra sequence the only best offers cost of cialis human genome and was one of Time Magazine's 2007 most important people. And he's been building new life. He builds chromosomes from scratch, inserts the new chromosomes in bacteria, and then "boots up" the organisms.

The DNA he produces in his laboratory are the largest molecules ever created by people and online purchase viagra he can individually determine what DNA to include and which to exclude. He can put in junk DNA that, when decoded, simply spells his own name, or is a poem. But, most importantly, he's working to build in code that can force the little bugs into becoming solar-powered crude oil factories.

The new organisms, which Venter says should be multiplying in the lab in the next 18 months, would need high concentrations of CO2 (say, from the smokestack of purchase levitra in canada a coal plant) to convert it to oil at maximum efficiencies. He can alter the octane of the fuel by altering the genes of the organism and, by selecting the cialis without a prescription best of thousands of molecules, he can "unnaturally select" the most efficient oil producers.

They're calling it 4th generation biofuel, and you can expect that it will be only the first application of this fascinating and somewhat alarming new technology. You can hear Venter himself explain the possibilities of this new technology with Chris Anderson at the recent TED conference in the video above.
