Putting the Spark in Electric Cars

The road ahead for automobiles
The Vice-Chairman of General Motors Bob Lutz said recently, “the electrification of the automobile is inevitable”. Soaring oil prices and growing concerns over pollution and carbon emissions are likely to propel a surge in interest in electric vehicles. The task at hand for carmakers is coming up with a product that is similar in price and performance to what is currently available. It will be a challenge to convince buyers who are spellbound by the throaty rumble of a big-block V8 to trade in their old cars, and upgrade to a zippy electric model with amazing mileage and a humble whirr. GM, BMW, and other major manufacturers are preparing for this challenge and they are testing the waters with a range of models including the Holden Volt. The rising price of oil will inevitably force buyers toward change but in the meantime it’s up to the marketing teams to make the product sexy. The Volt runs on a 150 horsepower electric motor backed up by a 1.4 litre petrol powered generator. It has a range of 65km on batteries alone and a top speed of 190km/h. The stylish four door compact, designed by Maximiliano Larroquette is expected to be on Sydney showroom floors by 2012. An unofficial price guide is $30,000+. An electric powered Formula One Championship is only a matter of time away. Would you buy an electric car? What factors might influence your decision?

The House of the Rising Sun

Solar energy solutions for your home
Simon Barnett is a man with a vision. He foresees a day when every modern home has a solar panel array on the roof. “It used to be a niche market, and the setup costs were prohibitive, but now all that is changing”, says Barnett as he proudly displays his quarterly home power bill for $1.19. Energy costs are going up and the need for a clean power alternative has never been more apparent. Worldwide the sales of photovoltaic solar panels increased fourfold in the three years to 2007. The increasing popularity of solar technology is due to the lower prices and higher power outputs of solar panels. Many governments also offer tax concessions to home and business owners as an incentive to adopt renewable energy sources. The panel array may include a Solar Thermal Collector (STC) for directly heating hot water and a Photovoltaic Module for generating electricity. So what does it cost? Barnett expects that the cost of installing a solar panel array into the average Australian home would now be under $10,000. With a 50% government rebate and immediate savings on power consumption it is undoubtedly a worthwhile investment. Have you considered solar power for your home? How do you feel about the cost? Do you think solar panels should be compulsory for new developments?

A Dead Ringer

What to do with old mobile phones?
If you’re anything like me, you’ve probably got half a dozen outdated mobile phone handsets sitting in a drawer somewhere gathering dust. Globally these old phones and other e-waste account for 70% of heavy metals in landfills. Lead, Mercury, Cadmium, and PCB’s & PVC’s are some of the potentially harmful substances that can leech into the earth after their disposal. Almost all electronic devices, and most certainly phones are made with a planned obsolescence. The phone may not work, or it may be perfectly functional for many years to come yet regardless it will lose its appeal as it ages. There will always be a newer model, with more features and functions just over the horizon. So what are your options? You can donate the handset to charity where it may find a grateful and needy recipient. You can send it back to the manufacturer to be recycled or you can try and offset the cost of your next phone bill by selling your old handset for what is likely to be a token sum. The amount you recover will depend heavily on the age, model, and compatibility of your handset. With the $0 upfront plans on offer for brand new phones it’s likely that 18 months after purchase your old phone will serve you well…as a paperweight.
What will you do with your old handsets? Do old phones have sentimental value? How long will you keep your current phone? What would tempt you to upgrade?

The Answer is Blowin' in the Wind

The future of wind farms
Some folk see them as graceful symbols of engineering technology and icons of man’s mastery over nature. To others they’re just plain ugly. Whichever way you look at them, wind farms are here to stay. Wind farms harness the power of air currents to generate electricity. The giant turbines operate in clusters from less than a dozen to several hundred depending on their location and size. The 55-turbine installation at Wattle point in South Australia generates 91 Megawatts of power. Estimates reveal the carbon footprint of installing a new turbine is ‘repaid’ in as little as nine months. There are currently 42 wind farms operating in Australia and the government is taking a leaf out of the European book with a further 521 projects under construction. This will help to ensure the energy security Australia will depend on in the future. Mitchell Clifford from Portland, Victoria is more than happy to accommodate a wind turbine on his property. The income from the lease supplements his farming income and the power supplied by the turbine runs everything on his farm besides the vehicles. “It’s common sense,” said Mr. Clifford “It’s clean, abundant and free”. Are wind farms the right approach to clean energy? Are they an eyesore? Would you allow a wind farm on your property?

There's a Bear in There...

Making room for native species
Loss of habitat is the single biggest cause of extinction of Australian native species. The clearing of land for agriculture has wiped out many species of birds and other tree dwelling creatures. Those that remain must contend with domestic and feral animals, and people. One of the most profoundly affected residents of the Australian bush is the Koala. The cute bear like marsupial, which was hunted almost to extinction for its pelt is now found in small colonies throughout Eastern Australia. The estimated population of Koalas Australia-wide is around 80000. A large number of Koalas live within range of human contact and in parts of Southeast Queensland and rural NSW the Koala can quite happily coexist with humans although it is facing pressure from urban development in these areas. About 4000 Koalas are killed annually by cats, dogs, and cars. Many more are injured or left helpless in infancy by the death or incapacitation of their mother.
In NSW injured animals are cared for by the Wildlife Information Rescue and Education Service, also known as WIRES. If you find an injured animal the following steps are recommended.
Step 1 - Remove any threat to the animal. This may mean locking up cats and dogs until the animal is rescued by a licensed rescuer.
Step 2 - Minimise stress by placing a towel or blanket over the animal, then gently place in a box. Put the box in a warm, quiet, dark room and DO NOT DISTURB. The stress associated with human contact can result in death.
Step 3 - Seek advice. If you live in New South Wales, call WIRES on 1300 094 737.
WIRES will give you advice on what to do until a trained WIRES rescuer comes to take the animal to a vet or WIRES foster carer. The foster carer will look after the animal until it is ready to be returned to the wild. Have you found an injured animal? What did you do with it? Would you consider becoming a WIRES volunteer? Should you confine your pets at night?

Riders on the Storm

Cyclists take on the RTA over bike paths
A recent survey revealed that nearly half of all cyclists cited the lack of suitable cycling paths as a deterrent to commuting by bike. While legally a cyclist has the same road rights as a motorist it is often impractical for them to share a roadway due to safety concerns. In 1991 the wearing of helmets while riding became mandatory and this law significantly improved the outcomes for many accident victims. Head injuries are the most common reason for hospitalization and 40% of patients are children under 14 years of age. Cycling advocates are calling for more action. Brian Day of the NSW Cyclists Action Group has slammed the RTA for scrapping plans to develop several major urban cycle paths in suburban Sydney. Brian said, “Every year the traffic gets worse, and people get fatter. Decent bike paths could alleviate both of these problems”. A spokesperson for the RTA said that in most cases cycle paths were the responsibility of local councils; and added that the RTA has developed over ninety kilometers of dedicated bicycle-only pathways in the Greater Sydney area in the past year alone. The RTA has revealed plans to develop a further 330km of bike paths in conjunction with the upgrading of major arterial roads into the CBD. Day said, “This is the same old story, they’ll have a few meetings but nothing will happen”. What are your thoughts? Do you ride to work or school? Do you feel safe riding in traffic and pollution? Do we need better bike paths?

It's in the Bag

The solution to plastic bag pollution
They’re cheap and convenient and everywhere you look, but what is the real cost of plastic bags?
Around 500 000 000 000 (yes five-hundred-billion!) bags are used annually worldwide. Most discarded bags end up in landfill where they take 300 years to photodegrade into tiny toxic particles. Although they can be recycled, fewer than 0.5% actually find their way into a recycling plant. The World’s oceans are filled with thousands of tons of plastic particles and every year about 100 000 marine animals die from plastic pollution. Sea turtles, fish, and marine birds are especially vulnerable to plastic pollution and they normally die of slow starvation after ingesting plastic, or drown after becoming tangled in bags and other debris. There are a number of ways to minimize the effects of plastic pollution. Using biodegradable bags is a start. Petroleum based biodegradable bags are an improvement but they release methane (a greenhouse gas) as they break down. Some stores use corn-based biodegradable bags that are ideal but not widely used due to their additional cost. Some countries such as Ireland imposed heavy taxes on plastic bags to successfully discourage their use. For the smart shopper the best solution is to avoid plastic bags and excessive packaging where possible and reuse a fabric bag to carry groceries. Do you use plastic bags? Would you consider an alternative? Should shoppers pay more for plastic bags?
