#Artificial'plants'could fuel future cars Scientists have taken a big step towards creating artificial'plants'that can use only sunlight to make gasoline
and natural gas to run future cars without polluting the environment. A research team has created an artificial leaf that produces methane,
the primary component of natural gas, using a combination of semiconducting nanowires and bacteria. The research builds on a similar hybrid system that yielded butanol, a component in gasoline,
and a variety of biochemical building blocks. It is a major advance towards synthetic photosynthesis, a type of solar power based on the ability of plants to transform sunlight,
however, synthetic photosynthesis seeks to produce liquid fuels that can be stored for months or years and distributed through existing energy infrastructure.
"Burning fossil fuels is putting carbon dioxide into the atmosphere much faster than natural photosynthesis can take it out.

is a significant step toward the substitution of fossil fuels with solar hydrogen. The demand for hydrogen as a clean fuel for vehicles and other applications is expected to increase.
Unfortunately it is produced currently from fossil fuel. Conventional approaches to hydrogen production using solar-powered photocatalysts have achieved a solar-to-hydrogen energy conversion efficiency of less than ten percent,
requiring improvements for real-world applications. A team of researchers led by Associate professor Masakazu Sugiyama and Project Professor Katsushi Fujii from The University of Tokyo and Associate professor Kensuke Nishioka from Miyazaki University have doubled now more than the solar conversion efficiency to 24.4 percent.
They used concentrator photovoltaic (CPV) modules, which includes a photovoltaic cell using a high-quality semiconductor crystal similar to the ones for lasers
The researchers also reduced energy loss by improving the connection between the CPV modules and electrolyzers, resulting in a solar-to-hydrogen energy conversion efficiency above 24 percent t

#Nanoscientists Convert Sunlight into Liquid fuel Using Nature and Technology Imagine creating artificial plants that make gasoline
and natural gas using only sunlight. And imagine using those fuels to heat our homes or run our cars without adding any greenhouse gases to the atmosphere.
By combining nanoscience and biology, researchers led by scientists at University of California, Berkeley, have taken a big step in that direction.
Peidong Yang, a professor of chemistry at Berkeley and co-director of the school's Kavli Energy Nanosciences Institute, leads a team that has created an artificial leaf that produces methane
the primary component of natural gas, using a combination of semiconducting nanowires and bacteria. The research, detailed in the online edition of Proceedings of the National Academy of Sciences in August, builds on a similar hybrid system, also recently devised by Yang and his colleagues,

Fuel factor Johan Steelant, a senior research engineer at the European space agency (Esa) and coordinator of Lapcat-II,
Fuel choice is important, especially as one consideration for any future hypersonic fleet will be to try to keep its emissions as low as possible.
This is why hydrogen was chosen, rather than a fuel based on hydrocarbons. What more, liquid hydrogen fuel is not highly combustible mid-flight.
Although hydrogen can be ignited, the risks of an explosion or fire are lower compared to conventional airline kerosene fuel.
Nasa used the same stuff to power the Space shuttle. f there is leak, the hydrogen is
hence there won't be a pool of hydrogen on the ground as is the case for kerosene.
Hydrogen, like kerosene, needs an igniter or a heat source to initiate combustion so it doesn't ignite spontaneously,
which simulates speeds up to Mach 1. 8. Hytex uses liquid hydrogen both as a fuel
The fuel consumption is one-fifth that of rocket engines, says Hideyuki Taguchi, leader of Jaxa hypersonic airplane research.
If the hydrogen can be sourced from natural gas, instead of from the electrolysis of water, the airfare tickets of a hypersonic trip could drop to about half the price of a business-class ticket.
An alternative fuel could be liquefied natural gas such as super-cold liquid methane; when stored as a liquid it needs far less space than gas. f a market for small business jets existed,
While the design consumes two times more fuel per second than a Mach 4 plane, it gets to the destination in roughly half the time so the fuel consumed overall during the trip is roughly the same.
A question of heat Dealing with heat will be a real concern. Anything travelling at Mach 5
we have lower fuel consumption and smaller tanks, which makes the vehicle again smaller, Steelant says.
In theory, it could simply increase power generation from traditional fossil fuels such as coal and gas, but stringent, legally-binding carbon dioxide emissions targets mean this is not possible.

Aside from producing renewable fuel and other products, you can use it to sequester waste carbon dioxide from industrial processes.
which don produce power on demand as a fossil fuel power plant does. For an individual consumer, having a battery behind the meter provides a great deal of flexibility in managing energy use.
Today, fossil fuels still dominate. However, the revolution is only now picking up steam. In fact, if we continue on at our current growth rate,
Beyond the obvious benefits of minimizing traditional fossil fuel energy technologies, the report also concludes that such a scale up of renewables in Africa s an affordable means to help meet fast-growing energy demand while increasing energy access, improving health,

Long island Compost also plans to convert the biogas to renewable natural gas that will be used to fuel its trucks on-site, reducing diesel consumption by 200,000 gallons annually.
An additional 1. 9 million gallons of diesel per year will be offset by injecting the remaining renewable gas produced by the digester into the National grid natural gas pipeline on Long island.
This will enable the gas to be used to fuel compressed natural gas vehicles in other areas. The project is part of the Cleaner, Greener Communities program, a statewide initiative encouraging communities to incorporate sustainability goals and principles into local plans and projects.

Gundersen said. he extraction cost of fuels continues to rise, while technology costs continue to fall.
Speculation that fossil fuel use overall is fast approaching a peak has been percolating for some time. A recent study published in the journal Fuel
and conducted by a team of resource geologists and environmental engineers in Australia and China suggested that global fossil fuel use would likely top out within the next 10 years,
and decline precipitously thereafter. They attributed much of this projection to decreased reliance on coal in China,
and economics are unlikely to be realized, given changes in energy consumption patterns in various countries and the status of ultimately recoverable fossil fuel resources globally. n a business-as usual situation,

#Teenage Girl Turns Plastic Trash Into Million-Dollar Biofuel An Egyptian teenager has discovered an inexpensive way to turn plastic trash into fuel
Azza Faiad ideas attracted the attention of the Egyptian Petroleum Research Institute. The institute gave the teen access to a lab
and its researchers in order to help refine her trash to fuel formula. Faiad discovered a cheap and plentiful catalyst called aluminisilicate that drastically reduces the cost of converting plastic waste into gases like methane and propane,
which can be turned into ethanol, what some scientists are calling iofuelbecause the organic chemicals from plastic polymers she extracts,
are the same chemicals extracted from vegetation to create ethanol biofuel. The process releases other chemicals that can also be recycled and sold.
Egypt produces a million tons of plastic trash every year, and it estimated Faiad process could convert that much trash into fuel worth$78 million every year.
In fact, she believes it could raise the total return to $163 million each year from Egypt plastic trash.
and she is now working on a patent for her trash to fuel process p

these problems can add up to rocketing fuel costs, excessive wear and tear, and the need to significantly oversize generators to cover relatively rare moments of fluctuating load,
For the grid at large, it could place strict limitations on how much renewable energy can be integrated before the need arises for excessive amounts of fossil fuel-fired power plants
Innovus is looking to maintain high fuel efficiency and the constant delivery of clean and stable power
while saving about 450,000 liters of fuel per year--a significant cost reduction for an island that must import all its fuel.
Mining companies pay roughly 70 cents per liter of diesel fuel, but often have to oversize their fixed-speed generator fleets to meet rare peaks in demand,
since it doesn imply any burning of fossil fuels. But pure battery systems still have a hard time penciling out in all but the most expensive fossil fuel markets.
