SAY NO TO A NUCLEAR AUSTRALIA | |
Transportation Has Come a Long Way.I recently found a story on hybrid sports cars and immediately thought 'Eh?? But aren't hybrids supposed to be somewhat lacking in power? How can this claim of a hybrid sports car be taken seriously?' So I went and had a bit of a look around to see what I could find. And it didn't take long for me to find some very interesting stories on the state of the hybrid industry at the moment. I concentrated on the models that showcase the sports performance side of the vehicle, and surprisingly, I found quite a bit on these flashy cars.Now, I like cars. I like watching motor sports, I like the fact that we've got something that will take us to distant places safely and quickly... and I just like driving a good, responsive vehicle. This is one area of conservation about which I sometimes feel torn. Do you have to compromise on the fun of driving in order to save a few greenhouse gas emissions? Well not any more, it seems. From what I've seen, there have been some great breakthroughs when it comes to power, fuel economy is at an unbelievable level, and new NiZn batteries promise 30% more power while being cheaper to produce and safer to store. It seems that we don't have a whole heap of excuses left for not considering this option when buying your next car. So let's have a look at a few. Ok, to start with, the one that took my eye originally, The Fisker Karma. ![]() Ok, so this one is flashy! I could actually see myself driving in this... except it's probably a little expensive for my budget. $80 000 USD will get you one of these luxurious monsters. This one combines a small gasoline engine with lithium battery packs. Apparently, if it's charged properly, it would use only 1 tank of fuel per year. As for the performance, 0-60 mph within 6 seconds and a top speed of 125 mph... I might have expected a little better from a sports car, but hey, that's not too bad. Most of us wouldn't use all of that allowance anyway. But still... this is a car-lover talking...
Then I stumbled across this little beauty, the Tesla Electric Roadster. ![]() ![]() Now, this one might be the one for me, I think. Jay Leno even has one! The lines of this vehicle are part Corvette, part Ferrari, part Porsche, and it looks great in black. An electric car that gives you 0 - 60mph in 4 seconds... that's more like it. It can travel up to 250 miles per charge and will set you back a mere $92 000 USD. No worries, I'll have two please, one for daytime use and one for night.
If you're looking for a larger vehicle, something like the Citroen C-Metisse might be the car for you. This looks like something that should be in the next batman movie, it's 4.74 m long, 2 m wide, and only 1.24 m high. It's front wheels are powered by a diesel engine for highway driving, while the particulate trap reduces the resulting emissions. The rear wheels are powered by electric motors to give the car a zero emission mode for around town. It can do 0-62 mph in 6.2 seconds, has a top speed of 155 mph and its makers claim it will average 42 mpg. The point to remember though is that this is at present only a concept vehicle. How about something a little more affordable? The ZAP Alias is set to be released at a cost of roughly $30 000. ![]() An all-electric three-wheeler vehicle, this one will be able to travel about 150 miles on one charge and go from 0-60 mph in about 7 seconds. For a small vehicle around town, that's not a bad deal... and it wins in the style department too. As yet, it's just another concept car, but with a 2009 release date you can place your order for one now.
![]() Can We Rely on Renewable Energy?"But can we really rely on renewable energy? What happens when the sun stops shining or the wind stops blowing?"This is a question that was asked of me some time ago. I had all intentions of answering at the time, but couldn't because of our absence from the net. So, expanding on the groundwork I initially put in, here is my response. Well, there are many different renewable energy sources. Some, like wind power and rooftop solar panels, are intermittent at a local level. But when they are spread over a sufficiently large area, with different climatic conditions, they are barely more intermittent than coal. It is unlikely that there will be no sun or wind anywhere across the electricity network of Australia. By deploying wind and solar across the landscape we can reduce any intermittency of wind and solar generators. And using these technologies in the home has the added advantage of producing electricity where it is used, so less energy is lost in transmission. On the subject of lost energy, did you know that about 11 per cent of the electricity produced at a big coal-fired power station is lost while being transported to the end user? So it seems that the problem of transporting power is something that all deliverers of power have to combat. So yes, both wind and solar power are subject to the weather. However, weather forecasting is very reliable and, in most cases, any lack of sun or wind can be predicted and compensated for (for instance, by cranking up hydro and biomass generation). But in contrast, coal-fired generation suffers unpredictable outages and breakdowns that can and do plunge the electricity grid into crisis. Solar power is particularly useful for delivering power at times of peak demand. Hot, sunny days when people are using their air conditioner, will generally be days when there is plenty of solar energy generated. And consider this... Solar water heating is hugely underused in sunburnt Australia. Less than five per cent of houses have a solar water heater. Some other countries, Israel, Spain and Ireland, are making solar water heating mandatory, while China has over 60 per cent of the world's installed solar water heating capacity. Now, some technologies, like hydro power are highly predictable and controllable. They can be deployed when it is most useful, providing either baseload or peak power. Eraring Energy has a number of hydro-electric plants and the Stanwell corporation is also using power derived by means of hydro generation. As for Tasmania... well, we've all heard about the successful use of hydro power in the Derwent River catchment. Bioenergy is another source of power that is being currently utilised in Australia. Woodlawn, near Sydney is Australia's largest bioreactor landfill. Veolia Environmental Services produces power generated by the methane that our waste produces. They also have plans in the works to incorporate a large scale windfarm on the Woodlawn site. Emerging technologies, like geothermal could theoretically provide large quantities of baseload power in Australia long before a single nuclear reactor can be built (they take 10-15 years) or a commercially feasible carbon capture and storage coal-fired power station could be developed. Geodynamics is a Brisbane-based company currently researching hot-rock technologies in the Cooper Basin. Solar thermal is another promising technology being researched by the Stanwell Corporation, one which I want to expand on soon. You can download a PDF file by the Environmental Protection Agency outlining the Stanwell Solar Concentrator here. So why is it that people still think that renewable energy sources are not viable when all these technologies are available? It seems to be hard for many to accept, but solar and wind are not the only alternative sources available to us. With a combination of several or all of these methods we are completely able to supply power in a safe and renewable way. We just have to get over the idea that it has to be either one technology or another. Links to Current ResearchThis will be a very quick entry to provide some useful links. don't really have the time to check into all of this research, but I'd love to hear your opinions on the things that you find here. Anything of interest that might give me some ideas for future posts would be appreciated. What do you want to see on these pages?CSIRO Department of Primary Industries Alternative Technology Association Australian National University Trinity College University of Sydney Murdoch University University of Newcastle Sustainable Houses.Well, hello there folks. Long time no see, eh? I haven't been here for quite some time now, due to an enforced vacation from the net. I'm back now though, at least for a few months, and I've decided to take up the good fight once again.I read a good report of sustainable houses from Radio National and wanted to provide some links for your perusal. These houses show that good things have been done in respect to the research and implementation of alternative energies. These are excellent examples of some of the things that can be done today to aid power production in your own home, and even in highrise offices. Please read these informative articles. Chippendale Terrace House... "A walk through a 100 year old terrace in the polluted inner city suburb of Chippendale. The house has been renovated and fitted to become self sufficient. Two adults and two children live there. It uses solar power which is connected to the grid so the house has no electricity bills, and actually feeds some power back into the grid. All their waste water and sewage is treated on site. The re-cycled water is used to flush the toilet and water the garden. They have a gutter filter which cleans and collects rainwater for drinking." Sustainable House in Central Australia... "Self-sufficiency in an arid climate. The first of several houses to for the Arrillhjere Corporation on aboriginal land, 30 killometres west of Alice Springs. It's a mud brick house, designed to be energy efficient and suitable an Aboriginal lifestyle in central Australia. The owner, Olive Veverbrants is keen to promote an environmental consciousness amongst her people. She is not yet on the phone, but is offering working holidays in return for expertise." Melbourne Water Autonomous House... "An ordinary house in suburban Melbourne that's far from ordinary . It's self sufficient in water. The residents are not connected to the water main and they don't pay water rates. Toby Murcott walks around the house with owner Marie Q. The water source is local rainfall, collected on the roof and stored in a large tank under the house. The house has water efficient appliances, and the grey water from the kitchen and laundry is recycled onto the garden. All the stringent health standards required by local council, such as e. coli levels, have been met. Some council representatives were supportive, some were not. Marie Q & James Stronelle believe there's an urgent need to reduce water consumption in Australia. They're keen to spread the word on how to achieve a system like theirs in an urban situation." Nimbin Permaculture House... "Lynne Malcolm visits a mud brick house situated on the Jarlanbah Estate, a rural residential subdivision, a few kilometres from Nimbin in sub-tropical Northern NSW. The house has a passive solar design, the walls are mud render applied over old corrugated iron and the centre of the house, which is mud brick gives the thermal mass. All the wood in the house is oiled with natural oils rather varnish or lacquer. There are Japanese style influences in the house's interior as Nigel lived in Japan for 12 years and his wife Yoko is Japanese. People are welcome to stay for bed and breakfast at Nigel and Yoko's house." And just to prove that an entire community can survive on alternative energy sources, check out what the people of Southwell, in Nottinghamshire England have done. All of this in an almost sunless climate. Imagine what we could do in Australia. English Eco-Village... "An energy efficient village that would make Robin Hood proud. Brenda and Robert Vale designed and built their first autonomous house in the village of Southwell, in Nottinghamshire. The house was in an historic area and its appearance had to meet strict heritage guidelines. Despite this the house collects its own water and is energy and water autonomous. Techniques inclued very thick walls and the house is very well insulated - the roof insulation is half a metre thick shredded newspaper. The windows are triple glazed with special low emmission coating. Following the success of these houses the Vales were asked to write building specifications for autonomous houses, houses with low CO2 emmissions and houses without any space heating. The local council wants to build a 'zero CO2 village' village based near Sherwood Forest in Nottinghamshire. The village was formerly a pit village. Now with the coal mines closed and local unemployment high, it's hoped demonstration Sherwood Energy Village will take the town forward." And just a quick one from the Aussie front, Council House 2 in Melbourne. Have a look at the government page dedicated to this highrise wonder and please, check out some of the links and have a really good look around the site. Council House II... "The City of Melbourne's six star green building CH2 opened in August 2006. An independent report evaluating the indoor environment quality and occupant productivity for the first year of full operations has now been released. The CSIRO report includes analysis from independent consultant Adrian Leaman of Building Use Studies in the UK, and indicates that productivity has improved by an impressive 10.9 per cent." |
