Submission + - Defense Research overhaul needed to prevent scientist shortage (acs.org)

Tator Tot writes: "Quoting C&EN News: "The Department of Defense will have to confront critical shortages of scientists and engineers if it doesn’t change how it recruits researchers and manages its science and technology enterprise, according to a report by the National Academies. The report finds that DOD scientists and engineers are not being used to their full potential, their career growth is limited, and the hiring process for new workers is slow and opaque.""

Remember that you have to get a permit from the state in order to frack. If the amount of waste generated is too much, or if the state doesn't have the resources to regulate the disposal of the fluids, then it's the state that should hold back from offering fracking permits until they have a better hand on the situation, assuming they are over burdened.

But then again, it's the state that is reaping the tax benefits of the increased O&G production. They will most likely be less concerned about the environment knowing they are getting much needed tax dollars.

And with respect to "land that has been completely sterilized" by frack fluid: Many times a company will drill using salt based water fluids (could be sodium chloride or calcium chloride, typically), or more often, the actual rock formation contains salt brine that incorporates into the fluid. The fluids are tested for salt, and if it is too high, it does have to be disposed of in a proper way. What you describe may most likely from high salt concentration than "some dangerous unknown brew of toxic chemicals".

99% is sand and water, typically, and the other 1% is a combination of the remaining products. Plus, Fido most likely injests more ethylene and propylene glycol from his dog food than what is present in these drilling fluids.

How would you feel if you knew that they use diesel as a non-aqueous based drilling fluid to drill these wells thousands of feet before they frack? Would you still drink tap water if knew they were drilling a hole using diesel as a drilling fluid? I mean, they've only been doing that for 60+ years.

I think the volume of ground affected by fracking is quite a bit larger than that hole being drilled into the volcano, and the goal with fracking is to mess around with the pressure under the surface, where ideally this is close a pressure neutral (volume changing, and that, I suspect will happen at/above surface level) system. Lastly, waste products from fracking tend not to be well controlled/cleaned except maybe on paper, the water (or other liquid) use here should be in a fairly closed system and shouldn't be introduced to toxic chemicals. Not that this is the wisest idea either, but an experimental site should provide interesting details as to the danger.

It bothers me when people discuss their uninformed opinions relating to a topic as fact.

1) The amount of fluid used in these deep shale formations is quite large, but even when you drill horizontally for a mile and then fracture 1000+ feet above and below the hole, you're still typically 12,000 feet below the surface (therefore the "frac zone" is from 11,000 to 13,000 feet). So even if you have DEEP water table of 2000 feet below the surface (where nearly none are this deep), the alleged "toxic chemicals" would have to travel a distance of around 9,000 feet (in this case) in order to taint the water supply. I've sat through enough presentations with REAL data obtained in the field to know that the fractures occur nowhere near these water zones.

2) The purpose of fracking is to increase the permeability of low-permeability shales (traditional reservoirs are in the mili-darcy range were unconventional reservoirs are more in the micro to nano-darcy range). They use high pressure fluid to open up the shale. Has nothing to do with adding pressure under the surface.

3) Waste products tend not to be controlled? Are you fucking nuts? The amount of regulation on what to do with the waste water is HUGE (and the assfucks that attempt to dump these fluids are massively fined), not to mention that a good chunk of fracking research goes into figuring out how to best reclaim and reuse of the fluid. Besides being 99% water and sand, the other additives are typically guar, biocides, polyacrylamides for friction reduction, corrosion inhibitors, citric acid, and ethylene glycol.

By the way, I work in a plant that makes a variety of additives for drilling and fracking fluids. Would you believe me if I told you that our facility is not capable or certified to handle any type of hazardous materials? That would mean that our company is going to get shut down by the government if they find out.... or maybe that the majority of additives for drilling and fracking fluids are non-hazardous?

TFA doesn't even link to where the actual report can be found (shame on you Chemical & Engineering News)

The actual report is behind a paywall, but has some summary points Sustainable Development of Algal Biofuels (2012)

If you look at the link that I included in the article, you'll notice that it links to that very article you describe. I even took the extra minute to search for the link in order to include it in the article :)

Submission + - Algal Biofuels Not Ready For Scale-up (acs.org) 1

Tator Tot writes: "Using today’s technologies and knowledge, a scale-up of fledgling algal biofuel production sufficient to meet even 5% of U.S. transportation fuel demand is unsustainable, says a report released last week by the National Research Council (NRC). The report examines the efficiency of producing biofuels from microalgae and cyanobacteria with respect to energy, water, and nutrient requirements and finds that the process falls short. The energy from algal biofuel, the report finds, is less than the energy needed to make it. In terms of water, at least 32.5 billion gal would be needed to produce 10 billion gal of algae-based biofuels, the report states. The study also finds that making enough algal biofuels to replace just 5% of U.S. annual transportation fuel needs would require 44–107% of the total nitrogen and 20–51% of the total phosphorus consumed annually in the U.S."

Submission + - Winemaking Waste Could Become Biofuel Starter (acs.org)

Tator Tot writes: Grape pomace, the mashed up skins and stems left over from making wine and grape juice, could serve as a good starting point for ethanol production, according to a new study (from the Journal of Agriculture and Food Chemistry).

Due to growing interest in biofuels, researchers have started looking for cheap and environmentally sustainable ways to produce such fuels, especially ethanol. Biological engineer Jean VanderGheynst at the University of California, Davis, turned to grape pomace, because winemakers in California alone produce over 100,000 tons of the fruit scraps each year, with much of it going to waste.
