#A 3d printed, Battery-Powered Rocket engine Nothing demonstrates engineering prowess and technical knowhow quite like rocket science.
Today at the Space Symposium in Colorado, the company unveiled its brand-new engine, named Rutherford--the first-ever battery-powered rocket engine.
But with Rutherford, the engines turbopumps get a much more condensed energy source. Instead of running on liquid propellant, the pumps are powered by electric motors with lithium polymer batteries.
This eliminates the need for extra spaghetti tubes and valves, which add weight to the engine
Its really only the advancement in battery technology that has enabled us to go to electric turbopumps, Beck says.
Rutherford is the first to incorporate battery power in its engine. If that wasn't unique enough,

#Organic framework serves as catalyst for the photocatalytic conversion of water into hydrogen Humanity's need for energy is ever-increasing.
However, the traditional energy sources are finite. In contrast, water and sunlight are available in vast abundance.
Scientists at the Max Planck Institute for Solid State Research in Stuttgart and from LMU Munich have created now a material that uses light to produce the versatile energy source hydrogen from water.
What is needed is a substance that directly uses the energy of sunlight to split the hydrogen-oxygen bonds in water.
or for producing carbon-based energy carriers. In fuel cells, electricity could be generated using hydrogen (and oxygen.
Hydrogen which is used currently in the industry to manufacture many important chemicals could also be made available in a more sustainable fashion.
#Shortening Organic solar cell Production One of the building blocks of the solar panel, solar cells are responsible for converting solar energy into electricity.
Most commercial solar cells are made from the inorganic crystalline silicon. Now, the U s. Dept of energy (DOE) Oak ridge National Laboratory (ORNL) has developed a method to save steps in the organic solar cell manufacturing process by introducing solvents into solar cell film production.
Usually, the thin filmssed by organic bulk heterojunction solar cellsre created by mixing conjugated polymers and fullerenes,
According to the DOE, organic photovoltaic solar cells have low efficiencies due to their small excition diffusion lengths
However, the information obtained from the neutron reflectometry will help scientists boost organic solar cell performance, according to ORNL. ptimization of photovoltaic properties provides information to manufacture solar cells with fully controlled morphology
and device performance, said Nuradhika Herath, the lead of the study. hese findings will aid in developing dealphotovoltaics,
a process required for fuel cells. The latest discovery detailed in Nature Communications, is a significant step toward lower-cost catalysts for energy production,
according to the researchers. hat unique about this paper is that we show not the use of metal particles, not the use of metal nanoparticles,

#New design points a path to the ltimatebattery Scientists have developed a working laboratory demonstrator of a lithium-oxygen battery
or lithium-air, batteries have been touted as the'ultimate'battery due to their theoretical energy density, which is ten times that of a lithium-ion battery.
Such a high energy density would be comparable to that of gasoline -and would enable an electric car with a battery that is a fifth the cost and a fifth the weight of those currently on the market to drive from London to Edinburgh on a single charge.
However, as is the case with other next-generation batteries, there are several practical challenges that need to be addressed before lithium-air batteries become a viable alternative to gasoline.
Now, researchers from the Univ. of Cambridge have demonstrated how some of these obstacles may be developed overcome,
and a lab-based demonstrator of a lithium-oxygen battery which has increased higher capacity energy efficiency and improved stability over previous attempts.
Their demonstrator relies on a highly porous, 'fluffy'carbon electrode made from graphene (comprising one-atom-thick sheets of carbon atoms),
and additives that alter the chemical reactions at work in the battery, making it more stable and more efficient.
While the results, reported in Science, are promising, the researchers caution that a practical lithium-air battery still remains at least a decade away."
"What we've achieved is a significant advance for this technology and suggests whole new areas for researche haven't solved all the problems inherent to this chemistry,
but our results do show routes forward towards a practical device, "said Prof. Clare Grey of Cambridge's Dept. of Chemistry, the paper's senior author.
Many of the technologies we use every day have been getting smaller, faster and cheaper each yearith the notable exception of batteries.
the challenges associated with making a better battery are holding back the widespread adoption of two major clean technologies:
"In their simplest form, batteries are made of three components: a positive electrode, a negative electrode and an electrolyte,''said Dr. Tao Liu, also from the Dept. of Chemistry,
and the paper's first author. In the lithium-ion (Li-ion) batteries we use in our laptops and smartphones,
the negative electrode is made of graphite (a form of carbon), the positive electrode is made of a metal oxide, such as lithium cobalt oxide,
and the electrolyte is a lithium salt dissolved in an organic solvent. The action of the battery depends on the movement of lithium ions between the electrodes.
Li-ion batteries are light but their capacity deteriorates with age, and their relatively low energy densities mean that they need to be recharged frequently.
Over the past decade, researchers have been developing various alternatives to Li-ion batteries, and lithium-air batteries are considered the ultimate in next-generation energy storage, because of their extremely high energy density.
However, previous attempts at working demonstrators have had low efficiency, poor rate performance, unwanted chemical reactions, and can only be cycled in pure oxygen.
What Liu, Grey and their colleagues have developed uses a very different chemistry than earlier attempts at a non-aqueous lithium-air battery
relying on lithium hydroxide (Lioh) instead of lithium peroxide (Li2o2. With the addition of water and the use of lithium iodide as a'mediator',their battery showed far less of the chemical reactions
which can cause cells to die, making it far more stable after multiple charge and discharge cycles.
and changing the chemical makeup of the electrolyte, the researchers were able to reduce the'voltage gap'between charge
A small voltage gap equals a more efficient batteryrevious versions of a lithium-air battery have managed only to get the gap down to 0. 5 to 1. 0 V
whereas 0. 2 V is closer to that of a Li-ion battery, and equates to an energy efficiency of 93%.
%The highly porous graphene electrode also greatly increases the capacity of the demonstrator, although only at certain rates of charge and discharge.
which can cause batteries to explode if they grow too much and short-circuit the battery. Additionally, the demonstrator can only be cycled in pure oxygen,
while the air around us also contains carbon dioxide, nitrogen and moisture, all of which are generally harmful to the metal electrode."
Finally, that nitrogen lowered the energy needed to kick electrons into the state in which they were available to split water.
Most commonly this might be done over a 24-hr period, with variable levels of solar-powered electricity available at any time of day
Conceptually, all of the energy produced could be stored indefinitely and used later when the electricity is needed most.
Alternatively, some energy could be used immediately and the rest stored for later use. Storage of this type helps to solve one of the key factors limiting the wider use of solar energyy eliminating the need to use the electricity immediately.
The underlying power source is based on production that varies enormously not just night and day, but some days,
or times of day, that solar intensity is more or less powerful. Many alternative energy systems are constrained by this lack of dependability and consistent energy flow.
Solar thermal electricity has been of considerable interest because of its potential to lower costs. In contrast to conventional solar photovoltaic cells that produce electricity directly from sunlight, solar thermal generation of energy is developed as a large power plant in
which acres of mirrors precisely reflect sunlight onto a solar receiver. That energy has been used to heat a fluid that in turn drives a turbine to produce electricity.
Such technology is appealing because it safe long-lasting, friendly to the environment and produces no greenhouse gas emissions.
Cost, dependability and efficiency have been the primary constraints. ith the compounds wee studying, there significant potential to lower costs and increase efficiency, said Nick Auyeung, an assistant professor of chemical engineering in the OSU College of Engineering, corresponding author on this study,
and an expert in novel applications and use of sustainable energy. n these types of systems, energy efficiency is closely related to use of the highest temperatures possible,
According to Auyeung, thermochemical storage resembles a battery, in which chemical bonds are used to store and release energyut in this case,
the transfer is based on heat, not electricity. The system hinges on the reversible decomposition of strontium carbonate into strontium oxide and carbon dioxide,
In comparison to existing approaches, the new system could also allow a 10-fold increase in energy densityt physically much smaller
which would drive a turbine to produce electricity, and then residual heat could be used to make steam to drive yet another turbine.
The researchers'analysis found that this energy-consuming intermediary step is not necessary for the conversion to happen.
Instead, an energy-producing"hydrocarbon pool"mechanism allows the zeolite catalysts to directly produce longer hydrocarbon chains from the original alcohols."
and requires energy. We showed this step doesn't occur, and that the overall reaction is slightly exothermic."
The research, supported by DOE's Bioenergy Technologies Office, has implications for the energy efficiency and cost of catalytic upgrading technologies proposed for use in biorefineries.
Uncovering the mechanism behind the reaction helps support the potential economic viability of ORNL's direct biofuel-to-hydrocarbon conversion approach."
Currently cars are pieced together on long assembly lines inside large factories that use massive amounts of energy.
#New tidal energy system could help POWER UK, say developers A British company, in conjunction with Oxford university researchers, believes it has devised a way to overcome this obstacle by creating a new type of horizontal axis turbine that can be used underwater at depths of up to 30 meters, at an economical cost.
Developed by Oxford university's Department of Engineering science in conjunction with Kepler Energy, THAWT uses a stressed truss configuration with carbon composite hydrofoil blades.
Guy Houlsby, professor of civil engineering at Oxford university, says their design is an improvement on the vertical Darrieus wind turbine used in some turbine systems."
Peter Dixon, chairman of Kepler Energy, says the patented turbine is the most efficient yet designed.

#New solar battery outperforms conventional lithium-iodine batteries By combining a solar cell and a battery into a single device,
researchers in the US have made the first truly viable solar batteries. Not only can this battery compete with regular lithium-iodine batteries,
it can actually outperform them, producing the same output with less charging, achieving an energy saving of 20 percent.
That 20 percent comes directly from sunlight, which is harvested by a flat solar panel on top of the battery.
Below, the researchers have installed a new type of electrolyte that replaces the lithium-cobalt oxide or lithium iron phosphate of regular battery electrolytes with water."
"The truly important innovation here is that we've successfully demonstrated aqueous flow inside our solar battery,"one of the team,
Yiying Wu from Ohio State university, said in a press release.""It's also totally compatible with current battery technology,
very easy to integrate with existing technology, environmentally friendly and easy to maintain.""The team is the same one that debuted the world first solar air battery last year,
and theye now improved on the design, by making the solar panel a solid sheet rather than a mesh,
because it no longer needs air flow to function, and by adding the water-based electrolyte.
Called an aqueous solar flow battery, this world-first design could be the basis of an entirely new class of batteries,
with or without the solar component installed.""In the original version, the researchers used a more conventional liquid electrolyte consisting of part salt
and part solvent (perchlorate mixed with organic solvent dimethyl sulphoxide, to be precise),"Nick Lavars reports for Gizmag."
"This has been replaced with water as the solvent and lithium iodide as the salt, which offers low-cost, high-energy storage capabilities."
"The solar cell is also super-efficient, known as a dye-sensitised solar cell. The team used a red dye called ruthenium to tune the wavelength of light it captures
According to the press release, these electrons are used then to supplement the voltage stored in the lithium-anode portion of the solar battery.
When they tested their solar batteries against conventional lithium-iodine batteries, they charged and discharged them 25 times to see how much electricity they would discharge each round.
Each time, both batteries discharged around 3. 3 volts. But as Lavars reports at Gizmag while the typical battery needed to be charged to 3. 6 volts to discharge 3. 3 volts,
the solar battery only needed to be charged to 2. 9 volts, while the solar panel made up the other 20 percent.
The team now wants to work on increasing this percentage, and are working towards 100 percent energy savings,
which would make it a fully solar-chargeable battery. But as they are, these solar batteries are already looking pretty damn practical."
"This solar flow battery design can potentially be applied for grid-scale solar energy conversion and storage, as well as producing'electrolyte fuels'that might be used to power future electric vehicles,"one of the team,
doctoral student Mingzhe Yu, said in the press release. The design is now patent pending, and the team reports the results of their testing in the Journal of the American Chemical Society S
#Amateur radio enthusiast makes contact with the International space station In the century or so since radio technology has been with us,
it's spawned a huge community of amateur enthusiasts and tinkerers alongside the professionals, and those part-time hobbyists are as active as ever in 2015.
Case in point: 52 year-old UK resident Adrian Lane, who recently had a brief but exhilarating conversation with the astronauts on board the International space station (ISS.
Remember that the ISS is orbiting more than 320 km (200 miles) above Earth and travelling at around 29,772 km h (18,500 mph),
The device is powered by lithium batteries and comes in both indoor and outdoor models. It only weighs between 2 to 3 kg (4. 4 to 6. 6 pounds) depending on the model
#New zealand will shut down its last large coal fired power generators in 2018 New zealand electricity company Genesis Energy has announced that it will shut down its last two coal fired power generators by December 2018-a bold step towards the country
the country will no longer be burning coal to generate electricity, and will stop pumping around 1,
"the Energy and Resources Minister Simon Bridges said in a press release. Because the majority of New zealand's energy already comes from geothermal, hydro,
and natural gas, giving up coal isn't as big a deal as it would be for other countries(*cough*Australia, the United states*cough),
*but the move is still a significant step towards a world where burning coal is no longer the cheapest and most reliable way to generate electricity."
"Historically, coal has played an important role in ensuring the security of New zealand electricity supply, particularly in dry years where our hydro-lake levels are said low
"What's really cool is that the decision was made by Genesis Energy solely on the basis of profits,
In fact, Genesis Energy Chief executive Albert Brantley estimated in a press release that the company will save around NZ$20 to 25 million (US$13 to 16.5 million) each year by not running the coal fired generators.
The two remaining coal-burning generators are located at Genesis Energy's Huntly Power station in Waikato on the country's North Island.
The power station itself will continue to run on natural gas for the foreseeable future. Over the past year and a half, New zealand has increased significantly the amount of electricity it produces from renewable energy,
with nearly 80 percent of its electricity coming from renewable sources in 2014 thanks to huge expansion in geothermal.
In comparison, the average OECD country only gets 22 percent of its electricity from renewables."
"Geothermal generation has doubled more than over the past decade, and for the first time in 40 years, geothermal electricity generation contributed more electricity than natural gas during 2014,
"Bridges announced to the press.""New zealand share of renewable electricity generation is already the fourth largest in the world
and the shift from coal will help us to achieve our ambitious goal of having 90 percent of New zealand electricity supply generated by renewables by 2025."
"Obviously the country's significant geothermal activity and small population gives it a unique advantage
