The Aye-Aye - Death by Superstition

Thursday, May 29th, 2008

In Madagascar lives a creature that looks so bizarre it is no wonder that the local Malagasy and Sakalava people believe it to be a symbol of death. The menacing omen comes in the shape of an aye-aye: Its piercing orange eyes, bony fingers, large incisors and bat-like ears definitely give this nocturnal primate a unique appearance. Some tribesmen even go so far as to claim that the aye-aye will sneak into your home at night and use its slender middle finger to pierce your heart.

These beliefs couldn’t be further from the truth. The creature that the local villagers are so petrified to come across spends most of its time searching out grubs, nuts, nectar and fruits rather than people to condemn to death.

Unfortunately, superstitions associated with the aye-aye result in the animal being killed on sight. It doesn’t help that the aye-aye is almost tame when compared to other wild animals. Aye-ayes are known to walk right up to naturalists and into busy villages, raiding farms for coconuts, mangoes or lychees. This makes them an easy target for individuals who want to avoid the curse by killing the primate.

In Gerald Durrel’s short novel, “The Aye-Aye and I”, Durrel describes how an aye-aye fearlessly crawled onto his shoulder and proceeded to gently probe the inside his ear for a tasty bug. Finding nothing, the aye-aye simply clamored back up into the trees with what is described as a disappointing grunt.

The aye-aye displays a unique foraging behavior when searching for its preferred food: It will tap at trees with its finger and use echolocation to find any grubs hiding underneath the bark. Once found, the aye-aye will rasp away at the wood with its teeth and insert the specially adapted middle finger into the larvae’s burrow to pull it out.

Naturalists once claimed the species to be extinct in the wild. Thankfully this is not the case, but aye-ayes are still a threatened species. It is disappointing to find an animal killed simply because of a superstition. Ancient beliefs are still strong in various parts of the world and it can be a hindrance to attempts at preserving a species.  It is a huge challenge working with cultures in third-world countries. Politics are always complicated, but it needs to be done.

With habitats shrinking, unlucky aye-ayes stumble into local villages more and more often and if found, don’t make it out. Hopefully, local people have begun to realize that no aye-aye has ever singled out a person to die.

BiodegradableStore - Plastic or Biodegradable?

Thursday, May 22nd, 2008

It’s not hard to understand why food on-the-go is so appealing. Pull a car full of hungry kids into the drive-through at your local burger joint and everyone leaves full and happy. In the mood for a coffee or egg sandwich on the way to work? It wouldn’t be a surprise with dozens of 50ft billboards advertising blended coffees or hot snacks. Plus, it’s quick and easy. Unfortunately, the plastic or Styrofoam containers last much longer than the sandwiches, drinks, burgers or fries that are devoured in a few minutes.

Non-biodegradable plastics will last indefinitely and plastic is everywhere:
According to the EPA “In 2006, the United States generated about 14 million tons of plastics in the municipal solid waste (MSW) stream as containers and packaging, over 6 million tons as nondurable goods [such as diapers and trash bags], and almost 9 million tons as durable goods [appliances].”

Recycling is definitely not eliminating plastics in the environment.  The Epa continues to explain that “overall recovery of plastics for recycling is relatively small — 1.4 million tons, or 3.9 percent of plastics generation in 2003”

With this in mind, companies like the BiodegradableStore develop containers made from biodegradable materials. Corn Plastics (PLA) and Bagasse (sugarcane) make up containers that will decompose in 35- 60 days in proper composting conditions.

PLA products look and feel exactly like regular plastic, but since they are made from corn, these items are 100% compostable. The added benefit of corn products is that corn stalks are known to grow quickly and are a renewable resource.

Bagasse, is more heat tolerant than corn plastics (which deteriorate at temperatures above 115 degrees (F))  and is made from sugarcane stalk pulp. Bagasse is comparable to thick paper and is ideal for serving hot drinks. It is even microwaveable. Bagasse takes advantage of sugarcane stalks that are typically discarded during the sugar making process.

There are many incentives for food and beverage distributers to start handing out these products with meals. Consumers will be happier knowing that the countless cups, plates, napkins and even bags, will return to nature and this would be a positive thought to dwell on while the food has left everyone feeling uncomfortably full.

Waterfree Technology - “Pee Green”

Monday, May 19th, 2008

Nobody likes to admit it, but there is one thing everyone has in common: Urination. It is just one of the many “benefits” associated with being alive, in addition to sweating, sneezing, coughing and shedding dead skin cells. The body excretes an array of substances, whether we like it or not. Excusing one’s self to relieve the bladder from part of the 800-1000ml of fluid that pass through the organ every day may be embarrassing, but the water wasted flushing away the urine is an even more controversial topic.

Toilettes and urinals use an average of 25% of a building’s water supply, while a leaky toilet adds to the problem; wasting up to 200 liters of water a day. Water free urinals are the next step in the world of resource management. Falcon Waterfree Technology, developed environmentally friendly urinal stations with the knowledge that a typical urinal wastes about 151,000 liters of water a year.

The idea of a water free urinal may sound unhygienic, but learning about the design will put any concerns to rest: Urine flows through a funnel shaped cartridge placed at the urinal’s base.  Once past the funnel, the urine is separated from the environment by a ‘sealant’ that floats on top of the urine (like oil on water) and proceeds to flow downwards, to the drain.  The air tight ring and sealant within the cartridge prevent any odors from escaping while uric waste is collected by this patented device. This ensures clean pipes and a clean smelling environment.

It is also important to note that settled water is a prime breeding ground for bacteria. Without this water there, there is no spot for the bacteria to multiply.

Falcon explains that the process “saves 100% of the water going through urinals, and therefore, 100% of the water and sewer charges. There is very little maintenance cost on a Falcon urinal as there are no moving parts and no flushometer. Drain lines remain free of calcification as no hard water is running through them. The only maintenance is an easy change of the cartridge, performed approximately three to four times per year.”

At around $300-600 per urinal, the technology pays for itself. Users of water free urinals claim to save anywhere from $100-200 per year with regards to water and maintinence costs.

It also helps to know that after using one of these hands-free and flush-free devices, no harm has come to the environment. It definitely feels good to “pee green” (catchy term used by a Falcon representative).

New Species Discovered in Brazil’s Cerrado

Friday, May 16th, 2008

Brazil’s Cerrado (translated to mean “inaccessible”) is thought to be the most biodiverse savannah in the world. Giant anteaters, armadillos, pampas deer, cougars, macaws and howler monkeys are just a few of the animals that make their homes here.

The maned wolf is one of the more unique species living in the region. This animal has a striking appearance, often compared to a fox on stilts with a bushy mane. As these solitary animals stalk their prey in this hot and relatively humid area, stepping on ancient soil and brushing past tall grasses, termites and leaf cutter ants diligently toil away around them.

Cerrado’s woodlands, now making up 21% of Brazil, are shrinking as the area is being converted to farmland. In an attempt to study the area in detail, scientist from Conservation International (CI) and various Brazilian Universities found 14 undocumented species in the Serra Geral do Tocantins Ecological Station and 440 species of vertebrates as a whole.

The most notable animals discovered last month, during this 29 day expedition, included a legless lizard, dwarf woodpecker and rough skinned horned toad. The snake-like lizard uses its pointed snout to make its way through the sandy soil of the Serra Geral. Legs would make this a less efficient process.

Excellent photos of these animals can be found on the National Geographic website.

It is always exciting to discover new species, especially ones that have evolved unique adaptations to adjust to their environment. It is also a reminder of how important it is to conserve sufficient portions of these areas before we lose more animals we never even knew existed.

Innovalight-Absorbing Light with Liquid Silicon

Wednesday, May 14th, 2008

Innovalight is getting a lot of attention: Time Magazine, The Economist, and Red Herring have all profiled this Santa Clara based company, while the department of energy has awarded them a fortune to assist with Innovalight’s unique solar panel development process.

Numerous photovoltaic companies have been covered by EcoWorld and solar power has raised the eyebrows of many: It is a great concept and is environmentally friendly, but can have incredibly expensive start up costs. Innovalight takes all this into consideration and has plans to market a new version of the solar panel concept: a nanocrystal solvent made from silicon. These silicon nanoparticles (also called quantum-dots) are extremely efficient; capable of absorbing various forms of light-infrared, ultraviolet and light from the visible spectrum - and able to produce multiple electrons from a single photon of light!

Silicon is the second most common element on the planet and is used in most solar panel products in today’s market.  Unfortunately, with suppliers constantly raising the price of silicon due to soaring demand, the less material used, the better.

The unique technology developed by Innovalight uses a silicon powder that has been converted to an ink rather than a solid. The silicon is suspended in a fluid which, in turn, can be printed directly onto polymer sheets to product flexible solar panels. This method is efficient and requires less silicon, which helps cut down on production costs. Plans for the future involve printing this versatile ink onto other products, such as glass or batteries.

Conrad Burke, President and CEO, is more than qualified to guide Innovalight towards a successful future with almost 20 years of experience preparing semiconducter and optical technologies for the market with such companies as Bookham Inc. and OMM Inc-while also being the first executive hire of the latter (a MEMS based optical switching systems company).

As stated on their website, Innovalight “is harnessing a proprietary silicon-ink process, developed by the company to print thin-film solar power modules. Leveraging the advantages of solvent-based processing, Innovalight will help accelerate the promise of more affordable solar power solutions for residential and commercial applications.”

Innovalight plans to market their product in 2009.

GeoFlow-Taking Advantage of Wastewater

Thursday, May 8th, 2008

Irrigation canals, water wheels driven by oxen, and smooth stones meant to catch dew drops that form during colder nights have all been used to water crops. Irrigation processes are constantly evolving. In today’s world, subsurface drip irrigation is one of the most efficient ways of water dispersal.

This subsurface system wastes little water by allowing it to drip out directly onto the root zone while a miniscule amount of the liquid is lost to drain-off or evaporation. This is an attractive choice, especially when one considers that water is not always an abundant resource.

Drip irrigation doesn’t only benefit those concerned about saving on water, however. This system is also an environmentally friendly alternative to the more wasteful systems (like sprinkler or surface irrigation). Ideally,when it is an option, wastewater (or effluent) is used to grow crops and maintain grasses, in order to preserve the limited freshwater for other uses. 

GeoFlow, based in Corte Madera, California and founded in 1990 with the goals of preserving water quality and quantity, specializes in wastewater irrigation systems and explains that “since the effluent is dispersed underground where it is absorbed in the biologically active soil layer, there is no surface contamination, no ponding, no run-off problems, no bad smells.” Another added benefit is that with an underground drip system, pesticides are not washed off plants with every watering, so plants do not need to be treated as often.

With GeoFLow’s WasteFlow system, secondary reclaimed water can be used and is pumped into the drip-field and released under plants on a time-activated cycle. The drip systems provided by GeoFlow are easily installed about eight inches in the soil, where treated effluent is absorbed.

GeoFlow takes things a step further with their patented RootGuard and Ultra-fresh treated emitters. Flexible tubing carries water under the soil where it is released by evenly spaced emitters. The emitters are equipped with self-cleaning filters while the non-toxic active ingredient in RootGuard, Treflan, keeps roots from growing around the emitters. The drip lines are also coated with the anti-bacterial, Ultra-Fresh, which inhibits bacterial growth inside the tubing and the emitters. This prevents slime build up inside the tube.

A subsurface drip system does have a high initial investment cost, however, ranging from $800-1500 per acre. Fortunately, Geoflow stands behind their product, offering a 10-year warranty for root intrusion, workmanship and materials.

The fact that the system is built to last many years, saves an abundance of water and is incredibly simple to operate has enticed many to switch over to drip irrigation.

BioFuelBox - Biodiesel Technology at Your Doorstep

Monday, May 5th, 2008

Numerous companies are coming up with techniques to use alternatives to fossil fuels. This is no surprise with fossil fuel prices sky-rocketing, oil supplies running out and concerns about the product’s effect on the environment becoming more abundant.

Unfortunately, demand for fossil fuels is still immense: According to the Energy Information Administration, almost 90% of the world’s primary energy production was reliant on fossil fuels in 2005.

Ethanol production is becoming more popular, but it is still unrealistic to think that it will replace the more efficient fossil fuels. It is good to have options, though: BioFuelBox makes the process of biofuel production a more attractive one by providing a unique product that is capable of manufacturing biodiesel from waste products ranging from algae and cooking oil to chicken fat and waste fish oil.

In addition to being so versatile, the BioFuelBox is designed to be portable: “Not only can our system be moved to where the feedstocks are, cutting down on the expense of trucking feedstocks to the refinery, but also, our unique patent-pending biodiesel process technology enables you to directly process wet feedstock such as algae or high FFA by product material such as animal tallow, chicken fat, or grease into ASTM quality biodiesel.“

Steven Perricone, President and CEO, has over a decade of experience in start up technological companies such as SonicWALL where Perricone played a major part in helping the company evolve from a small business of 20 employees to a company of almost 500. Another major name at BioFuelBox is Greg Anderson. As Chief Scientist at BioFuelBox, Anderson brings 24 years of biomedical, chemical, separation and fermentation science to the business and is the proud founder of McBain Laboratories.

BioFuelBox’s main goals are highlighted on their website which include:
• Ensuring that producers are able to take advantage of the widest range of feedstock including feedstock from waste streams.
• Providing opportunities to turn problem waste streams into revenue opportunities.
• Minimizing cost to make biofuel production accessible to more producers.
• Eliminating the technical challenges associated with conventional production methods.

The company is successfully eliminating almost every reason NOT to become a part of the biodiesel revolution.
