The electric car experience
After all the marketing hype (in the month when pricing for the Chevrolet Volt was finally announced), it's nice to get some real human stories from behind the wheel of an electric vehicle. Bernie Hobbs from the ABC Catalyst program provides just such an insight following her purchase of a Blade electric vehicle:
Apart from the non-standard petrol cap contents, there are a couple of stand out differences between driving this and a petrol car. First up, the much remarked upon quietness when you turn it on. If it wasn’t for the fans that keep the batteries cool you wouldn’t know it was going. A toggle on the dash lets you choose forwards or backwards, and once the motor kicks in there’s a nice futuristic electric whir. But reverse still gives me a start – this thing beeps at a pitch and volume that wouldn’t be out of place on a road train. Safety first, I guess.
For all the differences, after a while you forget you’re not driving a regular car. It’s got four gears – T, H (town and highway – too cute!) and two overdrives. Disengaging regen to shift gears isn’t much different from using a clutch. And a white hatchback isn’t a standout – although the cheesy clip-art style logo has turned the odd head. (Gotta say I’m starting to love the dagginess of that logo).
I sound like a total revhead, but I’m just really rapt to be investing in a form of transport that is headed in the direction I want to see us go. And when I say investing, I mean it. It's the most expensive thing I’ve ever bought that doesn’t have a kitchen and built-in robes.
The great thing is with an electric motor there’s very little in the way of maintenance, so over five years a hybrid winds up costing more. But the real beauty of the electric beast is that I charge it with 100 per cent green power. It costs me about $3.70 for 100 km worth of charge, and my contribution to climate change from that is the lowest on the road. (If I went with regular coal-fired electricity the CO2 emissions would be about the same as for a petrol hatch, so green power is essential for making this idea work).
Nissan's fuel saving technologies
Car Advice, July 8th: Nissan announced today in a report it is developing a range of technologies which will see much lower fuel consumption ratings in their future cars. In the report, Corporate Vice President of Nissan’s Powertrain Engineering Division, Shuichi Nishimura said,
"Nissan is continuously studying ways to reach the ultimate efficiency of its powertrains for further CO2 emission reduction. As a result of that, Nissan will introduce a series of innovative technologies on its 3 and 4-cylinder gasoline engines as well as a new high efficient hybrid system."
The first PURE DRIVE car is the new Micra, to be launched in Japan this month, which incorporates Nissan’s idle stop technology and showcases fuel consumption figures of 3.8L/100km.
There’s also the luxury Fuga Hybrid sedan on its way, which uses a clutch system that separates the petrol engine from the electric motor completely under certain circumstances. This helps to cut friction and loads between the two, and thus reduce fuel consumption.
A glass of water a day
Without any changes to their vehicles or anyone else's, Toyota have come up with the best ecodriving concept we have seen:
Lower your consumption: Drive with a glass of water - we at Toyota believe that's all it takes to lower your consumption by 10%. Aggressive acceleration and braking wastes fuel. By planning your driving and driving calmer, you use less fuel and emit less CO2. That’s the simple key to ecodriving.
Am I really supposed to put a glass of water on my dashboard? No, spilling water on your dashboard can of course be unsafe. The important thing is that you apply the principles of driving with a glass of water. You can do this by simply imagining a glass of water on your dashboard while driving.
And there's even an iPhone app for a 'virtual glass of water' on your dashboard:
iPhone app – ” A Glass of Water” records your driving distance, time, fuel consumption and water spilled. After each drive you can analyse your results and see on a map where you can improve your driving for the future. The results are automatically uploaded to this website and compared to other participants. You can of course participate in the challenge without the iPhone app as well.
Brumby goes solar while Gillard targets clunkers
The Age: Up to 10 large-scale solar power plants would be built in regional Victoria under a state government scheme to run a quarter of the state on renewable energy by 2020.
Promising to make Victoria the ''solar capital'' of Australia, Premier John Brumby set a target of 5 per cent of the state's electricity coming from large solar plants within 10 years. The plan won the immediate approval of the Australian Greens, with spokeswoman Christine Milne declaring that Mr Brumby was ''leaving Julia Gillard in his wake''.
The target would be met through the nation's first large solar feed-in-tariff - a subsidy that will pay solar companies a premium rate to make their technology competitive with coal, gas and wind power. The target is additional to the national 20 per cent renewable energy target, which is expected to mainly build wind farms.
Unfortunately, the federal government is compromising its own solar scheme to pay for an Australian version of 'cash for clunkers':
The Age: AUSTRALIA’S renewable energy industry was reeling yesterday after discovering a $520 million budget cut to low-emissions technology in the fine print of Julia Gillard’s ‘‘cash-for-clunkers’’ announcement.
Ms Gillard said that owners of pre-1995 vehicles will be able to claim $2,000 from January 1 next year to upgrade to cleaner cars. She estimated that handouts would benefit 200,000 of the 2 million owners of pre-1995 cars in Australia at a cost of $394 million over four years.
But the move will be financed by cutting into existing carbon reduction programs, including $200 million from the flagship solar power incentives and $150 million off the renewable energy scheme that provides rebates to householders for solar hot water and heat pump systems.
..
‘‘We were absolutely shocked and it’s fair to say the solar industry was stunned to learn that $220 million will be pulled from the flagship program,’’ said the Australian Solar Energy Society’s chief executive officer, John Grimes. ‘‘Taking inefficient cars off the road is a great initiative, but why would you rip the heart out of the solar program to do it?’’
..
Environment Victoria’s campaigns director, Mark Wakeham, welcomed the new standards for car emissions but said the government would pay $394 per tonne of carbon dioxide saved from the atmosphere. A basic emissions trading scheme would save a tonne of carbon for $20, he said.
Greenfleet welcomes any incentives to reduce transport emissions, but the experience from overseas is that 'cash for clunkers' is really an expensive form of economic stimulus to the automotive industry and is inefficient at reducing emissions. Cutting funding to the solar industry which needs a stable and supportive policy environment is the wrong approach.
The BP oil spill: will we miss another opportunity?
You might think that the worst environmental disaster in U.S. history would be a time for genuine reflection on habits of over consumption and progressive moves to more sustainable modes of transport.
But as we saw in the video last month, U.S. Presidents never 'miss an opportunity to miss an opportunity'. In this case it's the corn ethanol lobby that stands to benefit:
Slate: The blowout of BP's Macondo well has given the corn-ethanol industry yet another opportunity to push its fuel adulterant on the American consumer. And unfortunately, the Obama administration appears ready and willing to foist yet more of the corrosive, environmentally destructive, low-heat-energy fuel on motorists.
..
Yes, it's madness. And none of this even considers the effect that the ethanol rip-off is having on food supplies. Earlier this year, the Earth Policy Institute estimated that in 2009, the U.S. ethanol industry consumed 107 million tons of grain, or about 25 percent of total domestic grain production. That amount of grain, said the Institute, "was enough to feed 330 million people for one year at average world consumption levels."
BP's disaster in the Gulf of Mexico will force the offshore oil and gas industry to dramatically improve its safety procedures. That's a good thing. But if it only serves to strengthen the corn-ethanol industry, it will be a squandered opportunity, and another tragedy for the nation.
Ripping up roads
We often take roads for granted, but the enormous costs of building and maintaining them is starting to bite in many areas of the U.S.:
Wall Street Journal: Paved roads, historical emblems of American achievement, are being torn up across rural America and replaced with gravel or other rough surfaces as counties struggle with tight budgets and dwindling state and federal revenue. State money for local roads was cut in many places amid budget shortfalls.
..
In Michigan, at least 38 of the 83 counties have converted some asphalt roads to gravel in recent years. Last year, South Dakota turned at least 100 miles of asphalt road surfaces to gravel. Counties in Alabama and Pennsylvania have begun downgrading asphalt roads to cheaper chip-and-seal road, also known as "poor man's pavement." Some counties in Ohio are simply letting roads erode to gravel.
..
Rebuilding an asphalt road today is particularly expensive because the price of asphalt cement, a petroleum-based material mixed with rocks to make asphalt, has more than doubled over the past 10 years. Gravel becomes a cheaper option once an asphalt road has been neglected for so long that major rehabilitation is necessary.
Solar Impulse flies at night
The Australian, July 9th: A Swiss pilot has made aviation history by flying for more than 24 hours on nothing but solar power. The ultra-light Solar Impulse, flown by Andre Borschberg, 57, landed after 26 hours in the air about 4pm yesterday AEST.
Mr Borschberg took off from the airfield at Payerne, near Lausanne, into a clear blue sky shortly before 7am on Wednesday, local time, allowing the plane to soak up plenty of sunshine and fly in gentle loops over the Jura mountains west of the Swiss Alps.
The plane reached its maximum altitude of 8500m, with full power in its batteries, charged by sunlight through 12,000 cells on its wings and tail. As it grew dark, the plane descended to about 1500m, always staying within gliding range of the airfield so the pilot could land if the plane ran out of energy.
Bertrand Piccard, ballooning pioneer and psychiatrist who thought up the idea of building an aircraft to fly around the world on solar power, said he was thrilled by the flight. Mr Piccard, 52, and Mr Borschberg, a businessman and former military pilot, intend to build a second prototype that will fly the Atlantic and then, in 2013, around the world.
This is a considerable technological achievement but also provides an important lesson. A Boeing 747 carries up to 500 people at 900km/h. The Solar Impulse with a similar wingspan carries one person and cruises at 56km/h. The oil that fuels our cars, trucks and planes and which makes travel so accessible is a fabulously concentrated source of (still cheap) energy with no equivalent alternative. We should value it accordingly and use it wisely.
