Soccket Soccer Ball Generator, and Its Critiques

Soccket is a soccer ball that harnesses energy with every kick and volley it gets. Developed by Harvard grads, the toy boasts a successful Kickstarter campaign, surpassing a funding goal of $75,000 by over $17,000 last month. A pendulum inside the Soccket ball swings when the ball moves, generating clean energy for a rechargeable battery stored inside. According to Uncharted Play, Soccket’s makers, thirty minutes of play translates into three hours of light from its companion LED lamp. Pictured above, the little lamp is currently the only appliance it can charge, by being plugged directly into the ball. The ball itself seems relatively unencumbered by its tech features; according to the campaign’s Kickstarter video, Soccket is only about an ounce heavier than a standard soccer ball, and it's filled with specialized foam, so it won’t deflate.

The Soccket is one item among an extensive group of "eco" products that takes an activity usually independent of producing energy (in this case, a fun one) and turns it into an opportunity for clean energy generation. Recalling other kinetic energy devices, like the nPower PEG, which powers handheld electronics while you walk or ride a bike, there’s something immediately appealing about turning play into power. If I want to play soccer anyway during the day, why not get a ball that’ll power a light to read by at night?

However, the primary purpose of the Soccket -- and the main way it’s being marketed, to help poor communities around the world -- has generated some important critiques. There are much more efficiently powered LED lamps available, including these designed and built by a former EcoGeek writer. Is a soccer ball that powers a little lamp truly helpful aid to communities in need, or does it simply sound cool to well-intentioned, privileged individuals?

Aaron Ausland, of the blog Staying for Tea, argues that framing a soccer ball as an eco-friendly "solution" for poor communities "grossly overplays the potential of the ball and misleads investors and buyers about the social impact they get for their money." Ausland, in addition to his thought-provoking list of problems with the Soccket, points out that the Soccket’s generative powers are roughly the equivalent of "four weakly-rechargeable AA batteries." The conversation doesn’t end at his critiques, as Ausland posted a response from Julia C. Silverman, co-founder of Uncharted Play, who emphasized the company’s intent to work with communities, continue their evaluation of the Soccket’s impact, and focus on fun for children, noting that they capped the Soccket’s power so play for kids doesn’t become work for power.

Enhanced Plant Oil Production May Boost Biofuels

A new development using genes from algae to engineer plants to store oils in their leaves could lead to improvements in both biofuel production and the manufacture of animal feed. Researchers from Michigan State University have made plants with oily leaves, which were demonstrated when worms fed these leaves grew fatter than worms fed the unmodified version of the plants.

Most plant oils are stored in the seeds of the plant, and can be difficult to extract. But plants that store oils in their stems and leaves can be more easily processed to extract those oils. They also may produce greater quantities of oil than the original plants.

In addition to the potential use in biofuels, producing plants that store more oils in their leaves could also be a benefit for animal feed. Greater nutrition density from the same amount of crop could help feed more animals from the same area of cropland.

The lead scientist, MSU professor of biochemistry and molecular biology Christoph Benning, stated, "Many researchers are trying to enhance plants’ energy density, and this is another way of approaching it. It’s a proof-of-concept that could be used to boost plants’ oil production for biofuel use as well as improve the nutrition levels of animal feed."

Ongoing research will next move from demonstration of the concept to begin to explore specific applications "to enhance oil production in grasses and algae that have economic value."

Open Pit Mine to Be Reused for Pumped Storage

An abandoned open-pit mine in Canada is being proposed to be made useful once more as a pumped storage facility. The Northland Power Marmora Pumped Storage facility offers the possibility of turning a blighted, destroyed piece of land into something with value for advancing renewable power systems.

The pumped storage would be "five times the height of Niagara Falls,"according to the Globe and Mail, though the fact that it would have far less volume than Niagara gets far less attention. Nevertheless, the proposed facility would have the capacity to provide up to 400 megawatts to the grid for up to 5 hours.

Because of their relatively low cost, pumped storage facilities can have the capacity to provide much more power than more technical power storage methods like batteries or flywheels. Pumped storage facilities have both a rated capacity (like the proposed facility's 400 MW), which determines the peak power they are able to deliver, as well as the number of hours they are able to produce power at that level, which is determined by the size of the reservoir.

The location of the proposed facility is well situated in the midst of Ontario's heavily populated southeast, between Ottawa and Toronto, where there is high demand for power. Surplus power from both renewable and conventional sources can be used to pump water up into the upper reservoir during periods of low demand, and then that power can be used in place of costlier peaker power plants during periods of high demand.

Pumped storage is not for power production, but instead provides storage for power from other sources. It makes renewable power generation more effective by allowing surplus production to be stored for later use, rather than being lost at times when demand is low.

New Mitsubishi EV Has Improved Range and Style

Mitsubishi, which was one of the first mainline automakers to build a production electric vehicle, has unveiled a concept vehicle, the CA-MiEV, which has twice the range of the Nissan LEAF, and three times the range of its own predecessor, the I-MiEV, and it may do so at a lower price.

The CA-MiEV is supplied with a 28 kWh lithium-ion battery and is driven by an 80 kW (107 horsepower) electric motor. It will have a driving range of 300 kilometers (186 miles). It also has a wireless charging system that will allow the vehicle to recharge when parked in its spot, without having to be physically connected to an outlet.

Like many other EVs and hybrids, this also has the ability to connect with a smartphone or tablet so its cabin can be pre-conditioned before the driver arrives, and charging can be managed remotely. Regenerative braking, improved lightweight materials, and a very aerodynamic shape are also all factors in the improved efficiency of the new vehicle.

It's a better looking car than its predecessor, as well, although that is often the case with concept cars. With its far greater range, Mitsubishi is promoting this as a viable suburban EV, rather than just a city vehicle. There is not yet information about when, or if the CA-MiEV will begin production.

Electrolysis Catalyst Could Produce Inexpensive Hydrogen

Two Canadian researchers have announced a breakthrough that could produce catalysts for electrolysis at a fraction of current costs. The University of Calgary scientists are working to commecialize their discovery by 2014.

The FireWater Fuel (FFC) catalyst is more efficient at releasing breaking water into hydrogen and oxygen, and can be produced at a fraction of the cost of other exotic material catalysts. The FFC catalyst is based on ferrous oxide - rust. And, according to the researchers, the cost could be 1000 times lower than the cost of current materials.

With an efficient and inexpensive means for cracking water into hydrogen and oxygen, the feasibility increases for fuel cell batteries that can readily charge from renewable sources such as wind and solar when those sources are available and then discharge to provide electricity when demand is high.

The electrolytic catalyst is just one of the components that would be required for an entire system, but it has been an exepensive component of the system. With the FFC catalyst, hydrogen power takes another step towards being a greater part of the power mix in the coming years.

Bacteria May Provide More Sustainable Biofuel Production

Biofuel, like many alternative energy sources that are on the rise, faces its share of criticism. While it sounds ideal to create fuel from plants rather than limited fossil fuels, many methods of producing biofuel come at a high environmental cost all their own. Land used for biofuel production, for example, could be better put to use growing consumable crops instead of “sustainable” power for our cars.

Although biofuels from wood or grass may have a better future than less sustainable sources like corn, they are much more difficult to produce. The first step in turning biomass from grasses, trees, and certain algae into biofuel is getting through lignin, the tough material of their cell walls, and the compound isn’t an easy one to break down.

However there are some bacteria that digest lignin quite well, and harnessing the chomping power of these microorganisms could eventually lead to easier and more sustainable biofuel creation. While researchers at Mississippi State University had focused on identifying the digestive bacteria in panda poop, researchers at Brown University are also studying microorganisms that can break down lignin--and have figured out the chemical switch to start the lignin digestive process in the bacteria Streptomyces.

One of the few microorganisms that can consume lignin, Streptomyces begins the digestion process by releasing enzymes to break lignin down into its constituent compounds. This lignin-derived carbon, which the bacteria uses for growth and reproduction, is also where the magic begins for biofuel production: Streptomyces converts some of it into triglycerides, essential components of biodiesel, as well as other useful compounds. The Brown researchers’ previous work showed which genes encode enzymes to break down one particular compound: protocatechuate. When Streptomyces was grown where protocatechuate was present, PcaV, a protein usually attached to the DNA that stops those genes clusters from encoding, lost its affinity for DNA--and those unblocked genes gave the green light for enzyme production.

While being able to kickstart the lignin digestion process could lead to an easier transformation of woody biomass into biofuel, producing biofuel through Streptomyces on a commercial scale is still a long way away. Nevertheless, this research is a step forward for bacteriology as well as sustainable bioenergy.

Mapping a Better Walking Route

We've discussed the pedestrian resource Walk Score before, but there's a new company taking a different angle on rating the walkability of communities. While Walk Score rates addresses, Walkonomics rates streets. The UK-based company has only covered locations in England as well as US cities New York and San Francisco so far, but Walkonomics has the ambitious goal to rate every street in the world, according to criteria that go way beyond distance traveled. Using publically available data and user ratings to fill in the gaps, Walkonomics attempts to account for everything from hilliness and crime statistics to how much fun or relaxing it is to walk in any given area. Eight criteria are rated individually and tallied into a street's total score, so if some factors are more important than others to users, the score's breakdown is readily available.

Adam Davies, the company's founder, envisions Walkonomics will eventually offer customized directions based on each user's needs. Unfortunately, as Pando Daily reports, the company has a long way to go before this is possible. If they continue to rely heavily on publicly available data, opening in places like my small Connecticut city seems to be far off. However, if the company can continue to expand and gain more resources, they'd serve as another widely-available source that helps pedestrians, encourages walking, and emphasizes the importance of designing more pedestrian-friendly communities.

That last one's a stretch, to be sure--of course no app alone can engender or even promote changes in urban design. However, the more pedestrians literally take to the (safe to walk) streets, perhaps the more communities will increase their walkability and make structural changes to accommodate. Any technology that can empower pedestrians seems (pardon the obvious pun) a step in the right direction.

If you happen to live in New York City, San Francisco, England, or plan on walking through these places anytime soon and have a smartphone, you may find some use in their iPhone or Android app. According to their website, they've rated over 600,000 streets in these locations.

Cree LED Light Bulb Hits Milestone Price Point

Several years ago, the $10 level was a turning point for the widespread adoption of compact fluorescent light bulbs (CFL). Once the bulbs were priced that low, people were willing to take a chance to try one or two and see how they liked them and how they performed. Now, the same point has been reached in the development of LED lights.

A couple of years ago, 60-watt equivalent LED bulbs were priced around $30 to $40, and a couple years before that, they were closer to $100. Now, Cree is offering three LED bulbs with a price close to $10 (though only one of the three is actually under $10 retail price).

Cree is offering three different LED bulbs: a warm white 60-watt replacement, a daylight 60-watt replacement, and a warm white 40-watt replacement. These bulbs have the performance we've come to expect from LEDs, with a 25,000 hour lifespan rating and use only about 15% of the energy used by and equivalent incandescent bulb.

The Cree bulbs also have a "normal" looking package as compared to the now-familiar curly CFL. These LED bulbs also have a coated glass bulb, rather than a plastic covering like many other LEDs have had. Although the LED bulbs are not drastically more efficient than CFLs, the LED bulbs are also instant-on and are dimmable, which are features many CFLs do not have.

Cree is rolling out a selection of slogans to try to promote these bulbs, including "The Biggest Thing Since the Light Bulb," and "Its non-weird shape emits non-weird light." The company also is touting the below $10 price, although both of the 60-watt equivalents are priced somewhat higher. Nevertheless, this is still a big move in the lighting market.
