Honda's Clarity - A Car That Runs on Hydrogen and Emits Only Water
The first recipients of this technological marvel are Hollywood celebs Jamie Lee Curtis, husband Christopher Guest, '24' actress Laura Harris and film producer Ron Yerxa.

Hybrids require conventional gasoline, but the Honda Clarity is powered entirely by hydrogen.The fuel cell combines hydrogen with oxygen to make electricity. The electricity then powers the electric motor, which in turn propels the vehicle. Water is the only byproduct the FCX Clarity leaves behind.
Currently Honda aims to roll out just 200 cars a year. You don't have to be a celebrity to afford them, you can lease them out for $600 per month, including insurance.
Honda's creation FCX Clarity cars ushers in a new era of eco-friendly cars.The day isn't far when fuel cell cars will be a part of the mainstream and not just limited to celebrities.

Famous Five's Cool Invention - Air-Powered Go-Kart Race Cars
Mr. Langille and his four colleagues are thrilled with their project. “It was an awesome experience, very fulfilling. We’re excited to see it work so well because there were a lot of people who were doubtful and it was exciting to get an A+.”
The Famous Five in Enid Blyton's stories were popular for their investigative skills that kept the little readers spellbound throughout the world.
Dalhousie University's Famous Five are sure to keep Racing fans and scientists spellbound with their latest invention - air powered go-kart cars.Five Dalhousie mechanical engineering students David Alderson, Scott Allan, David Langille, Michael Roy and Dave Spencer had set upon an ambitious task for their year-long research project. They planned to develop a air powered go-kart cars. That's definitely a tall order.
To achieve it the students modified a 40-year-old snowmobile engine and ran compressed air through the engine to produce power similar to a gas engine. They attached the engine to a refurbished go-kart using two scuba tanks to house the air. The air is released through a standard scuba fitting with a high-flow regulator. The released air travels through tubing to a ball-valve connected to the foot pedal and throttle. “It operates much like a normal rotary engine,” says Mr. Langille.
The students are currently working on setting right the drawbacks. The major drawback is that it runs out of air quickly. But once the engine's capacity is refined one can look forward to a successor to conventional gas-powered engines.The students officially unveiled their air-powered go-kart at Kartbahn Racing in Bayer’s Lake Business Park last week and invited members of the media to take it for a spin.

Can Nanotubes Be A Source of Energy?
Image courtesy: Physorg
You have heard of carbon nanotubes, those quaint nano-stuff that can do many amazing things. Now some folks feel these can also play a role in the alternative energy domain. Read on.
When present in specially organized clusters, one could visualize carbon nanotubes as "nanotube forests." Within this forest, each individual nanotube acts like a tiny spring, and some scientists think that if you combine billions of them, they could do things that no steel spring could achieve.
Especially Carol Livermore. An assistant professor of mechanical engineering at the Massachusetts Institute of Technology, Livermore believes these stronger-than-steel nanotubes could open new possibilities for energy generation and storage.
How?
It is well known that you can store energy in the deformation of a spring. That is hardly a challenge. The main challenge with storing energy in springs is most don't store a lot of energy per unit of weight or volume. Livermore and is team feels that this problem can possibly be taken care of by carbon nanotubes because they can stretch incredibly far without breaking.
Nanotubes work like expansion springs - pull them and they stretch, release them and they are back to their original shape, while releasing energy. This property has already been shown with individual nanotubes. And, as mentioned earlier, these deformations can be for extreme lengths / dimensions. Now, take this useful property of nanotubes, and then combine billions of such nanotubes together into bundles. Now you can explore if extreme deformations of such bundles can produce vast amounts of energy. This is what Livermore intends to do.
With a grouping of nanotubes as long as an inch or two, it will be possible to test the qualities of the carbon nanotubes in a visible experiment. Instruments could measure the amount of force used, and the amount of energy returned when the spring contracts.
What are the possible applications of energy from such nanotube bundles? Some of the possibilities discussed are high-end mechanical watches that need winding only once, regenerative braking devices for bicycles etc. They are also thinking of ways in which the nanotube springs could replace some kind of batteries. Not exactly earth-shaking, but hey, this is just the beginning. Essentially, what these folks are looking at are ways to capture & store mechanical energy and release it to do useful things. I'm sure there are more interesting applications one can visualise and perfect if the technology works out fine.

Biocatalysts - Generics Pharmaceutical Manufacturers Go Green
Green chemistry incorporates concepts such as atom economy, convergency (higher process efficiency with fewer operations), reagent optimization (use of catalysis and more selective and recyclable reagents), and raw material efficiency.
One of the emerging green chemistry aspects is biocatalysts.
An advantage of these biocatalysts and of green chemistry in general, is the ability to manufacture a product in more generic facilities, compared to the demands of traditional chemocatalysis, which typically requires high pressure and high or low temperature reactors.
Another green chemistry strategy is telescoping, which aims to minimize the carryover of impurities from one process step to the next. The ability to make a product or an intermediate without any side products eliminates purification steps, saving time, energy, cost, and waste.
Interest in biocatalysis is high in the generics industry, in particular, as the generics manufacturers are actively seeking strategies to lower manufacturing costs and increase profit margins. It is predicted that biocatalysis technology will improve incrementally, with advances in proteomics enabling molecular evolution to be more directed and structure-based and less dependent on random mutagenesis.

Cow Dung, Agriculture Waste as Fuel - Ann Christy, MIT BioVolt Cells
Ann Christy, an associate professor of food, agriculture and biological engineering at Ohio State University, has been conducting new research into the use of cow waste to produce energy. According to Ms Christy's research, the bacteria in cow dung release electrons during the digestion on cellulose - "in the form of undigested plant matter in the cows' waste.
Ms Christy's team of scientific researchers have so far succeeded in producing half of the power required to energise an AA battery. "While that's a very small amount of voltage, the results show that it is possible to create electricity from cow waste," she commented.
This is hardly the first time cow dung is used as fuel. In fact, in developing and poor countries, cow dung has been used as a form of fuel for ages. What is significant about recent research are the more scientific methods used to explore the potential of cow waste as a fuel. Current use of cow dung in poor countries, though intuitive, might not be the most optimal way to use it.
It is hoped that researches such as these will enable us to accomodate animal and human waste as a significant alternative energy source. Don't look forward to waste powering your car anytime soon, but they could at least power your mobile battery!

Energy from waste is an interesting domain because of its double-benefits - creates energy from a free resource while improving the environment by sanitizing waste.
On related developments in the waste-to-energy domain, a team of students at the Massachusetts Institute of Technology (MIT) have also created waste-powered fuel cells. The MIT BioVolt cells are capable of running on plant waste and can generate electricity for household use in off-grid areas and developing countries.

UK Wind Turbines, Wave, Tidal, Hydro Energy Devices to Increase
The estimated fivefold increase in the number of turbines would be required to meet a new renewable-energy target for the UK under a plan detailed by the European Commission. Under the proposals, which are still to be agreed by member states, the UK would have to ensure at least 15 per cent of energy – in the form of electricity, heating and fuel – will come from renewable resources. Given limited scope to reduce fossil fuels used for transport and heating, renewable electricity supplies will need to make up between 30 and 40 per cent of the total.This could potentially mean a total of 5,200 turbines on land and 4,000 on sea, plus a mix of about 5,000 wave, tidal, and small run-of-river hydro and biomass devices by 2020, generating up to 46 gigawatts – or around 37 per cent of electricity demand.

EcoGlove Reusable Gloves, Uses Cold Plasma Sterilization
EcoGlove chairman Patrick Hampe claimed that the gloves would be cheaper for end users, reduce the risk of latex and chemical allergies, and friendlier to Mother Nature.
After use, the new gloves would be reprocessed by its manufacturers – sanitised and checked for defects – before being repackaged and sent back to the users.
A machine using cold plasma technology sterilises the gloves, and as a quality control measure, Hampe said any one set of gloves are only allowed to be reused seven times.
With EcoGlove, Hampe said the carbon footprint would be reduced by 60%, as there would be almost zero wastage.
Hampe said Loprol is a formula that is almost free from proteins, which trigger latex allergies, while most chemical allergies are linked to nitrile gloves.

Zenith Solar of Israel Pioneering Concentrated Solar Power Method
Rooftops all over Israel look strikingly similar: More than 1 million households in the nation of 7.1 million people have solar panels that produce hot water—a relatively simple technology that gained popularity after the 1973 Arab-Israeli war, when oil prices shot up sharply. As of the early 1990s, all new residential buildings were required by the government to install solar water-heating systems.
Zenith Solar, based in Nes Ziona near Tel Aviv, is a pioneer in a new type of solar energy that uses mirrors and lenses to focus and intensify the sun's light, producing far more electricity at lower cost. Compared with traditional flat photovoltaic panels made of silicon, this so-called concentrated solar power technology has proved in tests to be up to five times more efficient

Plastic Bags Not an Environmental Disaster?
Apparently, the problem started with a typo in an 2002 Australian Government report. It attempted to quote from an Canadian study 15 years earlier, which found that up to 100,000 marine animals had been killed over four years by "discarded nets" from the fishing industry. Somehow, the 2002 report replaced that phrase with "plastic bags." But finally science seems to be winning out. According to David W. Laist of the Marine Mammal Commission, and author of a primary research paper on the subject, "plastic bags don't figure in entanglement. The main culprits are fishing gear, ropes, lines and strapping bands." Professor of Marine Biology Geoff Boxshall concurred, “I’ve never seen a bird killed by a plastic bag"
Plastic bags are much cheaper than paper, which is why stores favor them. They take less resources and energy to produce, they're far cheaper to ship and store, they're recyclable and some are even biodegradable. Those savings aren't just for the stores, they translate into lower food costs and less damage to the environment, says this interesting post.
Surprising, I'd all along thought that plastic bags were an environmental disaster!

Iceland Turns to Geothermal and Hydroelectric Power to Cut Oil Dependence
In fact, Iceland, in its effort to reduce dependence on imported oil and clean up its environment at the same time, is trying to become the world’s first petroleum-free economy. President Olafur Ragnar Grimsson described his nation’s situation this way: “We have this eternal machine in this country created by the Almighty consisting of the fire below under the ground and the glaciers and the water that comes from the sky, and it goes on and on, year after year, century after century, creating this fascinating source of energy.”
So Iceland set out on an ambitious and risky program to develop its existing resources. Rather than import every joule of their energy, Icelanders drilled wells to tap hot underground water and built a grid of pipes throughout the entire city of Reykjavík to circulate the water to heat the city’s homes and offices. Soon, Icelanders were also using their volcanoes and many rivers to generate copious amounts of geothermal and hydroelectric energy

Pot-in-Pot - A Wireless Fridge, Refrigeration Without Electricity
Mohammed Bah Abba took this idea one step further. By placing one pot inside another and filling the gap in between the two pots with moist sand he was able to create a refrigeration system that requires nothing more than a little bit of moisture. The moist sand filling the gap between the two pots draws heat away from the inner pot and dissipates the heat through the evaporation of the moisture. The inner pot is filled with perishable foods that would normally last for mere days, but with this system can last for weeks. Mohammed Bah Abba's invention awarded him the Rolex Award for Enterprise, and has been recognised as a very important contribution to societies with limited energy resources, or where energy costs are prohibitive. Many families no longer rely on their children to "rush sell" their food goods and can now sell when the demand arises due to the reduction of spoilage
Mohammed is a a lecturer at polytechnic college in Northern Nigeria, and comes from a family of pot makers. He drew on his childhood experience and invented his Pot-in-Pot cooling system in 1995 and received the Rolex Award in 2000.

The solar cells convert light to electricity with an efficiency of 7.2 percent, which is a record for this type of cell. Solar panels typically convert 16 percent to 20 percent of light into energy. But the advantage of the organic dye cells is that they also convert low light and that they can be ‘tuned’ for specific wavelengths.

Jayant Baliga's IGBT's Could Have the World's Smallest Carbon Footprint
One of Baliga's inventions is responsible for eliminating the need for more than 100 gigawatts of power, which translates to a reduction in carbon dioxide emissions of about 1 trillion pounds per year. Now, he is working to make his footprint even smaller by pursuing new inventions that further improve energy efficiency.
The energy saved by the use of IGBTs in electric motors and energy-efficient light bulbs alone equals 100 gigawatts, meaning that new one-gigawatt, coal-fired power plants won't need to be built to match the former demand. There are economic benefits as well - to the tune of $2 billion for each plant that does not have to be built.

Boeing Makes First Ever Hydrogen Battery Flight
"For the first time in the history of aviation, Boeing has flown a manned airplane that was powered by a hydrogen battery," Boeing chief technology officer John Tracy told a news conference at the firm's research centre in the central Spanish town of Ocana.
The plane, which used propellers, flew at a speed of 100 kilometres (62 miles) an hour for about 20 minutes at an altitude of about 1,000 metres (3,300 feet) using only the hydrogen battery for power, Boeing said in a statement.
The director of the Ocana research centre, Francisco Escarti, said the hydrogen battery "could be the main source of energy for a small plane" but would likely not become the "primary soruce of energy for big passenger planes".

Wind-powered Airplanes by Dr. Josef Popf. Airplane Hybrids?
But the deeper I delved into the problem, the more plausible it started to appear. Then, after about two solid months, I found the answers I needed and filed for a patent.”
Essentially, it’s not so different from the hybrid systems employed by hybrid cars. As an airplane cruises or comes in to land, the turbine super-charges high-capacity batteries. That energy can then be used during future take-offs and landings. The trick, according to Popf, is to use the wind turbine at high altitudes, where the thinner atmosphere puts less stress on the airplane, preventing excessive drag.

Fuelstar Combustion Catalyst Increases Fuel Efficiency, Cuts Fuel Costs
The car-engine unit is about the size of a soft-drink can and is plumbed into the fuel supply line.
When fuel flows through the unit on its way to the carburettor or injection system, minuscule particles of metallic tin are released into the fuel and are carried through to the combustion chambers.
These particles are far too small to damage engine components. The tin changes the combustion characteristics of the fuel, giving a more complete and more prolonged fuel burn, resulting in improved efficiency and performance.
California Environmental Engineering tested a Fuelstar installed in a 6.9-litre Nissan diesel truck and found it reduced fuel consumption by 27 per cent. It also brought down emissions of CO2 by 30 per cent and particulates by 24 per cent.

BASS Founder Ray Scott Invention Helps Prevent Lake Fish Kills
But when the man who founded the BASS sport fishing empire looked out one morning from his Pintlala home and saw his lake filled with dead fish, he put on his thinking cap and designed a product that now is being produced by a Wisconsin-based company.
Scott turned to specialists at Auburn University to get answers to many questions. He learned that the days of hot weather had depleted the oxygen from the bottom of the pond.
The Auburn officials told Scott that if he wanted to ward off future fish kills, he needed to invent a device that would ensure oxygen levels remained balanced in the pond. Scott went to work on a water-circulating device.
Over the next 10 years, he continued to tinker with his invention, building a series of prototypes and testing them.

Saving the Coral Reefs with BioRock Mineral Accretion Technology
Corals lay the foundation for underwater colonies of marine life. If the coral die out, the effects run straight up the food chain to the fish that humans depend on for food. Unless we find a way to assist the coral to recover, we will reduce the available food stock for humans from the sea.
Perhaps there is a way for humans to undo the damage we have caused and allow our foodstocks to return to sustainable levels. Bio-Rock Mineral Accretion Technology may be one way that we can put things back to normal. Biorock Technology, or mineral accretion technology is a method that applies safe, low voltage electrical currents through seawater, causing dissolved minerals to crystallize on structures, growing into a white limestone similar to that which naturally makes up coral reefs and tropical white sand beaches. This material has a strength similar to concrete. It can be used to make robust artificial reefs on which corals grow at very rapid rates.
