Explore related topics: fuel cell • kids • toys
Or adults, really. :) Probably more educational than an Elmo doll, this fuel cell car experiment kit teaches kids how to assemble a car that runs on water – i.e. a fuel cell. Talk about teaching the future! For ages 10 and up (I guess that includes me as well), “The Fuel Cell X7 edition is designed to be accessible to more users, both in terms of content and price. The manual focuses more on building and designing a fuel cell car, rather than the comprehensive lesson on the science of fuel cells and solar cells found in the original version.”
Features include:
* Assemble a working fuel cell car
* Discover how fuel cells work
* Use a unique reversible fuel cell
* Learn about the potential alternative energies for automobiles
* Learn about fuel cell car design
This would be a pretty cool gift for the budding engineer this holiday season…

A glimpse over green technologies training and jobs in South Florida – December 2009
View all » An installation program started recently by electric utility companies to place solar generating plants on roofs is capturing a lot of requests from property owners. The main idea is to install photovoltaic (PV) energy systems connected to the utility’s electric grid. Under this program, utilities will add to their grid energy generated from solar mini plants distributed on top of roofs and grounds of buildings, including residential, commercial and public locations. Some of the companies leading this initiative include Duke Energy and Progress Energy in North Carolina.
The Distributed Solar Energy Program of Charlotte-based Duke Energy estimates future investments of about $50M to generate 50 Megawatts. Under Duke’s business model, the utility owns, installs, operates and maintains the solar panels that generate electricity directly to the grid. The utility pays a rent to the property owner and at the same time expands its source of green energy to comply with State laws. The first phase of the program is just starting with a pilot project that includes only 4 large commercial buildings that will generate 4.6 Megawatts. The second phase includes additional large non-residential buildings and the third and last phase includes residential customers with installations starting by second quarter of next year.
Progress Energy from Raleigh, has signed contracts with 10 commercial owners under its SunSense program. Their model is different. In their case, the property owner buys, install, operates and maintains the solar system selling energy to Progress at $0.18 per Kilowatt-Hour. Their initiative also includes a Solar Water Heating program. In Orlando, Florida, 17 BP gas stations have canopies with solar panels interconnected to their grid.
Both companies are identifying more candidates for their programs. Selection criteria include age of the building, distance to transmission lines and amount of sunlight received.
More information about Duke Energy Solar PV Distributed Generation Program is available at www.duke-energy.com/north-carolina/renewable-energy.asp. Details about the Progress Energy SunSense program in North Carolina and Florida can be found at http://www.progress-energy.com/environment/ras/solar.asp.

Hybrid Solar Panels Combine Photovoltaics with Thermoelectricity
Columbia University and N.Y. engineering firm Weidlinger Associates are developing a layered approach that will draw electricity from the sun's energy in multiple ways
By Larry Greenemeier
.
HYBRID SOLAR PANEL DIAGRAM The hybrid solar panel that Yin designed has as its outermost layer a clear protective cover, followed by a layer of thermoelectric material, a layer with plastic tubes (called the functionally graded material interlayer) to carry water that will cool the other layers while also carrying away heated water, and a bottom layer of reinforcing plastic.
© COLUMBIA UNIVERSITY
Tar and shingles are hardly environmentally friendly materials, so the U.S. Department of Energy (DOE) hopes to soon help homeowners and businesses replace the roofs over their heads with something greener. To that end, the DOE awarded Weidlinger Associates, a New York City-based structural engineering firm, a $150,000 grant earlier this month (matched by a 10-percent commitment from the state) to develop durable hybrid solar roofing panels with integrated photovoltaic cells and thermoelectric materials that harvest the sun's energy to produce both electricity and hot water for buildings.
Weidlinger is working with Columbia University in New York City on the project, which the engineers and researchers hope will convert at least 12 percent of collected sunlight into electricity. This would be an improvement over the 5- to 10-percent conversion rate possible with relatively inexpensive thin-film plastic solar cells, although a far cry from the most complex (and expensive) solar cells, which have achieved a conversion rate as high as 41.6 percent.
These new photovoltaic thermal hybrid panels presently exist only as prototypes. Beneath the clear, outermost protective cover is a layer of photovoltaic cells, followed by a layer of thermoelectric material, a layer with plastic tubes (called the functionally graded material interlayer) to carry water that will cool the other layers while also carrying away heated water, and a bottom layer of reinforcing plastic. The photovoltaic cells convert the sun's electromagnetic radiation into electricity, while the thermoelectric layer converts the sun's heat into electricity.
The water tubes are crucial to the design. Typically, when photovoltaics heat up they begin to lose their efficiency at normal operating temperatures in a sunny environment, says Greg Kelly, Weidlinger's director of sustainable design. The design created by Huiming Yin, an assistant professor of civil engineering and engineering mechanics at Columbia, incorporates a capacity to cool down the photovoltaics while also heating water for use in the building to which the panels are attached.
In addition to being tested in Columbia's lab, a number of these panels will be installed atop a 6.4-square meter shelter located on the roof of the Frederick Douglass Academy, a New York City high school that specializes in the education of disadvantaged and underrepresented educational groups. Once the shelter is built, students will monitor the performance of the panels. "What we have to do is demonstrate a general commercial viability," Yin says, adding that this means getting both the technology and its associated costs just right. The researchers have yet to calculate the cost of the technology per watt, a standard measuring stick to determine whether a renewable energy project can compete with established fossil-fuel technologies.
If this phase of the project is successful, the work done by Columbia and Weidlinger could move to a second phase within six months. That second phase is likely to offer the researchers $1 million in DOE funds for a year to further develop the technology, Kelly says, whereas a third phase would likely involve as much as $10 million to prepare the technology for production. "We're looking at a five-year process to come to market, assuming all goes well," he adds.
The DOE is behind the technology thus far. "Solar panels have not achieved market penetration due to high initial costs and inefficiency, but the hybrid building-integrated panels from this project will be part of the building's skin and significantly more efficient," according to a DOE statement e-mailed to Scientific American. "These less costly and more durable panels are suitable for residential and commercial projects for new construction and renovations."
The broad concept of building a solar panel that is tough enough to act as a roof panel yet sensitive enough to capture as much of the sun's energy as possible is likely feasible, says David Ginger, an associate professor of chemistry at the University of Washington in Seattle. "Of course, putting all these ideas into the same package in a cost-effective manner is often more challenging than pitching the idea on paper, which is why you want clever engineers trying out new designs and then testing them in real-world environments," he adds.
And although this idea of "building-integrated photovoltaics" (BIPV) is not new, the Columbia-Weidlinger multilayered hybrid design is different from anything currently available to builders. SolarWorld AG in Germany, for example, sells a technology it calls Energyroof, which consists of panels covered with solar laminates that generate electricity but does not include a layer of thermoelectric material.
In October, The Dow Chemical Company announced its Powerhouse Solar Shingle, which the company says can be integrated into rooftops with standard asphalt shingle materials. These solar shingles, which feature thin-film copper indium gallium selenide (CIGS) photovoltaic cells, are expected to be available in limited quantities by mid-2010 and projected to be more widely available in 2011. In 2007, the DOE had given Dow $20 million in funding to develop building-integrated solar arrays for the residential and commercial markets.
Once Weidlinger and Columbia create their panels, the engineers will have to decide how best to keep them waterproof and resistant to fire, Kelly says, adding, "We also want to get parity with the weight of existing roofing systems."

While if done cheap could be worth it, CSP solar is far more eff at 25-30% for electric and has higher quality heat for space heating or hot water. Cost in mass production under $3k/kw and can be fired by most any bio or other fuel if power, heat needed and the sun don't shine.Reply | Report Abuse.workforlivn at 04:19 PM on 12/31/09
Why does the government need to be involved? There's is no "invention" reported here. When the costs of conventional electricity rise to the level of solar then the free market will provide the answer. We dont need the government trying to pick winners and losers. They have too few minds compared to the free market.

-----------------------
PV panels being of dark colors (mine are dark blue) always get hotter and less efficient in the sun, even in winter, regardless of being electrically connected or not.
This is a good idea that needs more experimentation.Reply | Report Abuse.mo98 at 06:22 AM on 01/04/10
Roofing with used PC motherboards may be another alternative to bitumen. When CMOS versions of cloud computing may mature to the PC, lots of wasted power to run CPU's will be saved, The demand for unwanted motherboards may then hopefully, be reduced by the availability of full solar spectra panels similar to the prototype discussed.Reply | Report Abuse.PV Geek at 10:52 AM on 01/05/10

Hybrid Solar Panels Combine Photovoltaics with Thermoelectricity
Columbia University and N.Y. engineering firm Weidlinger Associates are developing a layered approach that will draw electricity from the sun's energy in multiple ways
By Larry Greenemeier
.
HYBRID SOLAR PANEL DIAGRAM The hybrid solar panel that Yin designed has as its outermost layer a clear protective cover, followed by a layer of thermoelectric material, a layer with plastic tubes (called the functionally graded material interlayer) to carry water that will cool the other layers while also carrying away heated water, and a bottom layer of reinforcing plastic.
© COLUMBIA UNIVERSITY
Tar and shingles are hardly environmentally friendly materials, so the U.S. Department of Energy (DOE) hopes to soon help homeowners and businesses replace the roofs over their heads with something greener. To that end, the DOE awarded Weidlinger Associates, a New York City-based structural engineering firm, a $150,000 grant earlier this month (matched by a 10-percent commitment from the state) to develop durable hybrid solar roofing panels with integrated photovoltaic cells and thermoelectric materials that harvest the sun's energy to produce both electricity and hot water for buildings.
Weidlinger is working with Columbia University in New York City on the project, which the engineers and researchers hope will convert at least 12 percent of collected sunlight into electricity. This would be an improvement over the 5- to 10-percent conversion rate possible with relatively inexpensive thin-film plastic solar cells, although a far cry from the most complex (and expensive) solar cells, which have achieved a conversion rate as high as 41.6 percent.
These new photovoltaic thermal hybrid panels presently exist only as prototypes. Beneath the clear, outermost protective cover is a layer of photovoltaic cells, followed by a layer of thermoelectric material, a layer with plastic tubes (called the functionally graded material interlayer) to carry water that will cool the other layers while also carrying away heated water, and a bottom layer of reinforcing plastic. The photovoltaic cells convert the sun's electromagnetic radiation into electricity, while the thermoelectric layer converts the sun's heat into electricity.
The water tubes are crucial to the design. Typically, when photovoltaics heat up they begin to lose their efficiency at normal operating temperatures in a sunny environment, says Greg Kelly, Weidlinger's director of sustainable design. The design created by Huiming Yin, an assistant professor of civil engineering and engineering mechanics at Columbia, incorporates a capacity to cool down the photovoltaics while also heating water for use in the building to which the panels are attached.
In addition to being tested in Columbia's lab, a number of these panels will be installed atop a 6.4-square meter shelter located on the roof of the Frederick Douglass Academy, a New York City high school that specializes in the education of disadvantaged and underrepresented educational groups. Once the shelter is built, students will monitor the performance of the panels. "What we have to do is demonstrate a general commercial viability," Yin says, adding that this means getting both the technology and its associated costs just right. The researchers have yet to calculate the cost of the technology per watt, a standard measuring stick to determine whether a renewable energy project can compete with established fossil-fuel technologies.
If this phase of the project is successful, the work done by Columbia and Weidlinger could move to a second phase within six months. That second phase is likely to offer the researchers $1 million in DOE funds for a year to further develop the technology, Kelly says, whereas a third phase would likely involve as much as $10 million to prepare the technology for production. "We're looking at a five-year process to come to market, assuming all goes well," he adds.
The DOE is behind the technology thus far. "Solar panels have not achieved market penetration due to high initial costs and inefficiency, but the hybrid building-integrated panels from this project will be part of the building's skin and significantly more efficient," according to a DOE statement e-mailed to Scientific American. "These less costly and more durable panels are suitable for residential and commercial projects for new construction and renovations."
The broad concept of building a solar panel that is tough enough to act as a roof panel yet sensitive enough to capture as much of the sun's energy as possible is likely feasible, says David Ginger, an associate professor of chemistry at the University of Washington in Seattle. "Of course, putting all these ideas into the same package in a cost-effective manner is often more challenging than pitching the idea on paper, which is why you want clever engineers trying out new designs and then testing them in real-world environments," he adds.
And although this idea of "building-integrated photovoltaics" (BIPV) is not new, the Columbia-Weidlinger multilayered hybrid design is different from anything currently available to builders. SolarWorld AG in Germany, for example, sells a technology it calls Energyroof, which consists of panels covered with solar laminates that generate electricity but does not include a layer of thermoelectric material.
In October, The Dow Chemical Company announced its Powerhouse Solar Shingle, which the company says can be integrated into rooftops with standard asphalt shingle materials. These solar shingles, which feature thin-film copper indium gallium selenide (CIGS) photovoltaic cells, are expected to be available in limited quantities by mid-2010 and projected to be more widely available in 2011. In 2007, the DOE had given Dow $20 million in funding to develop building-integrated solar arrays for the residential and commercial markets.
Once Weidlinger and Columbia create their panels, the engineers will have to decide how best to keep them waterproof and resistant to fire, Kelly says, adding, "We also want to get parity with the weight of existing roofing systems."

Faster Than a Speeding Carrot: A Racing Car Made Entirely from Recyclables and Vegetable By-Products
Biomaterials researchers build a Formula 3 racing car from recyclables and compostable materials that has been clocked at 238 kilometers per hour
By Pippa Wysong
.X
FROM COMPOST TO COMPETITOR: WorldFirst is an unusual automobile made mostly using recycled plastic water and juice bottles, potato starch, carrot fibers and other materials one normally expects to find in the recycling or compost bin.
© UNIVERSITY OF WARWICK
A Formula 3 racing car made entirely out of recycled and renewable materials could be a sign of things to come in the automotive industry. At least, that is the hope of some British researchers who have built WorldFirst, an unusual automobile made mostly using recycled plastic water and juice bottles, potato starch, carrot fibers and other materials one normally expects to find in the recycling or compost bin.
The car reaches a top speed of 238 kilometers per hour and has been driven more than 800 kilometers for testing and demonstrations since it first rolled out of the lab in April. WorldFirst was tested at Brands Hatch—a motor racing circuit in Kent, England—driven by professional racer Aaron Steele.
Engineers at the Warwick Innovative Manufacturing Research Center (WIMRC) at Warwick University in England built the car as part of a larger project to develop new materials for use in the automotive and health care sectors that meet the goals of sustainable development. The WorldFirst racing car also is a response to two emerging trends in auto racing: an interest in a greener approach to the sport and the escalating costs of fielding a competitive Formula 1 racing team that have chased away some sponsors, says James Meredith, a WIMRC biomaterials engineer and WorldFirst project manager. (Formula 3 competitions are generally considered to be stepping-stones for drivers looking to compete in Formula 1 races.)
The WorldFirst car is a proof-of-principle vehicle that shows it is possible to use recycled and reused materials to build a functioning automobile. "The choice of which materials to use was based on how easy they were to work with, what shape the part we needed to manufacture was, and what mechanical properties were needed," Meredith says. Recycled carbon fiber was used for the large parts of the car such as the engine cover. Fibers made from flax and hemp were used for simple parts such as the bargeboard and bib, which are used to improve aerodynamics. Other major parts of the car are made from carbon and fiberglass.
The outer part of the steering wheel was made from Curran, a polymer made by CelluComp in Scotland and derived from carrots and other root vegetables. Curran has properties similar to those of glass or carbon fiber-reinforced polymer, Meredith says. The inside of the driver's seat was made from soy-based foam, while the cover consists of a fabric made from flax.
The tires are still made of rubber, although tire manufacturer Avon Tyres (a division of Cooper Tire & Rubber Co.) claims it is working to eliminate one of the biggest toxic polluting compounds in them, polycyclic aromatic hydrocarbons (PAH), which are used to help soften the rubber. PAHs that leach from old tires disposed of incorrectly can contaminate soil and water, and the chemical compound can become airborne in tire fires.
The WorldFirst racing car runs on biodiesel derived from chocolate fat. Meredith notes that the chocolate fat used for this purpose is actually a waste product in the food industry. "Whenever you burn a biodiesel made from waste materials," he says, "it can be argued that it is carbon neutral."
The radiator is coated with PremAir, a catalyst material that converts the ozone portion of the car's emissions into oxygen—something that is desirable since at ground level ozone is a pollutant.
How strong and how durable are the materials in this car? "In terms of their durability—we are still working on this," Meredith says. "All the parts we have made to date are still going strong. Natural fibers will most likely have a lower resistance to weather effects as the fibers will absorb moisture if exposed and then degrade. Recycled carbon fiber and glass fiber with recycled resins should have equal durability to standard materials."
Biofiber components derived from a variety of plants are already being used in some non-racing car components, says Mohini Sain, a professor of forestry at the University of Toronto's Center for Biocomposites and Biomaterials Processing. Some manufacturers use biomaterials in door panels, consoles, tire covers and floor mats. Eventually, as the technology improves, biomaterials will be used in larger components, says Sain, who was not part of the WorldFirst project. Already, some biofiber materials perform as well as glass fibers and are less dense. Sain notes that biofibers do break down when exposed to moisture, but the fibers are coated in resins and plastics to counter this.
Meredith predicts the car should last as long as any other racing car, saying, "The natural fiber parts have lasted well although their weather resistance does not appear to be as good as existing materials." In the end, "ideally all the natural fiber products can be shredded and composted, carbon parts can be recycled again—albeit with a small amount of degradation," he adds.

Faster Than a Speeding Carrot: A Racing Car Made Entirely from Recyclables and Vegetable By-Products
Biomaterials researchers build a Formula 3 racing car from recyclables and compostable materials that has been clocked at 238 kilometers per hour

FROM COMPOST TO COMPETITOR: WorldFirst is an unusual automobile made mostly using recycled plastic water and juice bottles, potato starch, carrot fibers and other materials one normally expects to find in the recycling or compost bin.

A Formula 3 racing car made entirely out of recycled and renewable materials could be a sign of things to come in the automotive industry. At least, that is the hope of some British researchers who have built WorldFirst, an unusual automobile made mostly using recycled plastic water and juice bottles, potato starch, carrot fibers and other materials one normally expects to find in the recycling or compost bin.
The car reaches a top speed of 238 kilometers per hour and has been driven more than 800 kilometers for testing and demonstrations since it first rolled out of the lab in April. WorldFirst was tested at Brands Hatch—a motor racing circuit in Kent, England—driven by professional racer Aaron Steele.
Engineers at the Warwick Innovative Manufacturing Research Center (WIMRC) at Warwick University in England built the car as part of a larger project to develop new materials for use in the automotive and health care sectors that meet the goals of sustainable development. The WorldFirst racing car also is a response to two emerging trends in auto racing: an interest in a greener approach to the sport and the escalating costs of fielding a competitive Formula 1 racing team that have chased away some sponsors, says James Meredith, a WIMRC biomaterials engineer and WorldFirst project manager. (Formula 3 competitions are generally considered to be stepping-stones for drivers looking to compete in Formula 1 races.)
The WorldFirst car is a proof-of-principle vehicle that shows it is possible to use recycled and reused materials to build a functioning automobile. "The choice of which materials to use was based on how easy they were to work with, what shape the part we needed to manufacture was, and what mechanical properties were needed," Meredith says. Recycled carbon fiber was used for the large parts of the car such as the engine cover. Fibers made from flax and hemp were used for simple parts such as the bargeboard and bib, which are used to improve aerodynamics. Other major parts of the car are made from carbon and fiberglass.
The outer part of the steering wheel was made from Curran, a polymer made by CelluComp in Scotland and derived from carrots and other root vegetables. Curran has properties similar to those of glass or carbon fiber-reinforced polymer, Meredith says. The inside of the driver's seat was made from soy-based foam, while the cover consists of a fabric made from flax.
The tires are still made of rubber, although tire manufacturer Avon Tyres (a division of Cooper Tire & Rubber Co.) claims it is working to eliminate one of the biggest toxic polluting compounds in them, polycyclic aromatic hydrocarbons (PAH), which are used to help soften the rubber. PAHs that leach from old tires disposed of incorrectly can contaminate soil and water, and the chemical compound can become airborne in tire fires.
The WorldFirst racing car runs on biodiesel derived from chocolate fat. Meredith notes that the chocolate fat used for this purpose is actually a waste product in the food industry. "Whenever you burn a biodiesel made from waste materials," he says, "it can be argued that it is carbon neutral."
The radiator is coated with PremAir, a catalyst material that converts the ozone portion of the car's emissions into oxygen—something that is desirable since at ground level ozone is a pollutant.
How strong and how durable are the materials in this car? "In terms of their durability—we are still working on this," Meredith says. "All the parts we have made to date are still going strong. Natural fibers will most likely have a lower resistance to weather effects as the fibers will absorb moisture if exposed and then degrade. Recycled carbon fiber and glass fiber with recycled resins should have equal durability to standard materials."
Biofiber components derived from a variety of plants are already being used in some non-racing car components, says Mohini Sain, a professor of forestry at the University of Toronto's Center for Biocomposites and Biomaterials Processing. Some manufacturers use biomaterials in door panels, consoles, tire covers and floor mats. Eventually, as the technology improves, biomaterials will be used in larger components, says Sain, who was not part of the WorldFirst project. Already, some biofiber materials perform as well as glass fibers and are less dense. Sain notes that biofibers do break down when exposed to moisture, but the fibers are coated in resins and plastics to counter this.
Meredith predicts the car should last as long as any other racing car, saying, "The natural fiber parts have lasted well although their weather resistance does not appear to be as good as existing materials." In the end, "ideally all the natural fiber products can be shredded and composted, carbon parts can be recycled again—albeit with a small amount of degradation," he adds.
