Subaru though innovative at inception are very sluggish and not refined in terms of fuel efficiency as they could have been. This has not diminished owner approval and resale values apparently. I guess better late than never.

Looks like one scary parade mask for a small car.

I posted last year that a shared axis motor pair as described would eliminate the differential and offer another traction control point. On a single alxe vehicle, 0 turn radius is possible. Thee may be benefits in lower power control unit even though duplication be necessary, the cost and reliability could be a positive. The comments went on to the pros and cons of wheel motors as I recall. Although this is a concept so in cyberspace still, I applaud this approach .

(one of )My other hat is a Horticulturalist (Arborist). All the Qualifying learning we reach is through our teachers trainers and academic study. This is informed and enhanced by experience and inquirey. This is why I find the 'know it all statements' from the uninformed so amusing and ridiculous. back to the topic. Another study (CSIRO) conducted recently to examine growth response and so cabon uptake in a high CO2 low water regime as the models and evidence suggest we are moving toward, showed that the study Eucalyptus trees E? were able to tolerate a lower water availability and still show accelerated growth. The only problem for me is that we know the high volatile oil content of Eucalyptus and the particular lignotuber defense mechanism from wild or bushfire which has favoured the E. genus expansion into a drying continent also ensures and promotes a fire standard . This and other weed like behaviour make the E an increasingly dominat species and translates to the reduction of the fire intolerant and low fire risk 'lush and rain or high rainfall forests'. THis leads to an acelleration of specie change to the fire culture E , more fire more CO2 release etc. But I can see how without reference to the specific situation or a wider understanding of forest and vegetation, one may wrongly believe that the warming and hey why not the drying (as this study alluded to) will lead to faster tree growth and so a higher atmospheric CO2 reduction.

Sulleny, - would make a very 'average' vacuum or used car salesman.

will the "all electric machine" - -honda FC" have regenerative braking as an efficiency measure? If so will that not be stored in a battery? The same could store directly from any electrtic supply - renewable wind etc fom a primary source. -That makes sense.

Aside from exotic materials including plastics, and the benefit of electronics and computing, the ICE engine seems unlikely to change in capability or usefulness so we should prepare for an ongoing relationship with fuel suppliers at likely not reduced extent for some decades. The question then is what are the least obnoxious downsides available?. It seems so simple at a time before the cloud condenses. fuel builders and processors already have a suit of products, more of some - depending on the plants technology and feedstock. It seems reasonable to prefer lower emission fuels in anticipation that technology advances and the realisation of appropriate feedstock resources will follow demand. I would think that an energy constricted world will be favorable also to niche producers providing bulk resources to chemical and plastics as well as fuel blenders, feeds for fuel cells? and domestic CHP? etc. The existing delivery constrictions may then not be an issue in smaller scale (than 10%+) of consumer fuel mandate. To understand that (in the manner of electron flow or musical chairs) that implimenting new green options as smartgrid + renewables + vehicle charging require that the supporting infrastructure is implemented in tandem. This is the priorcondition for realisation and the answer to the endless uninformed criticism to progreess. Further more without such refinement, the existing paradigm is likely to increasingly entangle and choke.

Very significant, expect more from this. The AIST have many freely downloadable PDF's on matters of interest. Cheatomorpha aereas collected in Vietnam was the most glucose-rich sample of these samples, about 300 mg of glucose per gram of organic matter.

25-40 year lifetimes? http://www.energy.soton.ac.uk/solar/connectors.html Photovoltaic modules have no moving parts and last upwards of 25 years with no maintenance aside from the occasional cleaning. Realising such a long lifetime for entire PV systems relies on the continued integrity of all system components. The installation of modules in building facades and other structures has necessitated the use of push fit connectors to enable quick and easy inter-module dc electrical connection. New applications for photovoltaics such as roof shingles place further performance demands on electrical connectors such as shown in Figure 1. The dc interconnection between PV elements represents a potential weak link in a PV system. http://www1.eere.energy.gov/solar/pv_basics.html 2. Assumes 30-year period of performance and 80% maximum rated power at end of lifetime http://anglodutchservices.co.uk/blog/?p=142 Incentive programmes in Italy, Germany and Spain have created manufacturing volume that’s bringing down costs. Solar panel prices dropped 30% last year alone due to an increase in output and a drop in orders because of the recession. PV-Panels had been expected to last for 20 years and price calculations were based on this (with a free energy source, purchase and installation represent almost the entire price of solar power) Long lifetime It has shown that more than 90% of the panels on the market 10 years ago are capable of still performing well after 30 years of life, albeit with a slight drop in performance. We all know that 40-year photovoltaic panels will be on the market in the near future. Hot water collector panels are already expected to last 35 years with little loss of efficiency producing 70% of hot water needs. And quality heat pumps are known to have a life span of 30 years plus too outliving boilers 3 to 4 times, using only 30% of the energy, the rest is solar.

I frequently feel inclined to criticize the tendancy of posters on the site when they disagree over technology proposals when there could well be a range of applicable uses, as well as range of areas where the technology is innappropriate. No sense in poo-pooing the technology from a viewpoint that will not be a likely application. What will be a productive application will likely follow tradition of consumers finding application and especially true in these new transport or energy options. Thats not to say critical comment isn't a benefit or thoughtful, just that we need to remember as we can't know the intention or future innovation of most any product that there is a perception of limited imagination of such comments .

Henrick, You would be aware that there is a mulyiplier for aircraft emissions related to altitude. The formulas vary based on altitude and engine type so this is only for example. "The IPCC, for example, has estimated that the climate impact of aircraft is two to four times greater than the effect of their carbon dioxide emissions alone."

so-called Sequential multi-port fuel injection, controls the fuel even better for each particular cylinder, A Cummins 6.7 I-6 liter diesel, weighs 1100+ pounds, but without all the cleanup paraphernalia, to merely reach still dirty T2B5 levels of cleanliness. A comparable Chrysler 6.4 liter Hemi V8 gasoline ICE, Except that Sequential DI is the correct term and the cummings motor is a heavy duty heavy flywheel ruggedised unit while the Chrysler is a light duty and high rpm unit so the two cannot be compared. you should compare like with like.

This returns to the possibility of end of life (30yrs) the glass roof is still purposefull. Sydneys plethora of parking meters could use these chargers to provide both a charge boost (interconnected) or street lighting as a way of better service for meter parkers. Solar voltaic glassware should be cpable of waterproof and other amenity to dual purpose the high single use cost. Panel designs that meet this requirement will have no end of life. Also spray on or thin film replacements should be available by then. Standard panel sizes and fixings for Metricated countries, extra incentive for change to those that aren't. (so they don't feel completely left out!)

Simply a disaffected know it all that ha no humility or reason. Not even funny. But a good example of the morons you can meet at most public drinking houses.

And no probs if there aren't bowsers available as these craft are often used as fashion accesories so could mostly get by with a mild extension cord.

This 'Copenhagen wheel' Can do that and more.Well worth alook. http://www.bikeradar.com/news/article/prototype-wheel-uses-braking-energy-to-power-bike-24400

The city scene on the Island of Sodor, home of Thomas the Tank Engine could benefit from such a useful bus as this. We know that bertie hs been feeling like a holiday for some time and has recently been feeling unwell. Bertie's strongest characteristic is his friendly grin and his readiness to help any engine prepared to admit that - - just sometimes - - roads have their uses as well as rails so any replacement (on a trial basis) would need to have all these attributes. Gentlemen, I believe this may be what we are looking for.

There wouldn't be a taxi in Sydney that doesn't run LPG, but LPI is a new development and not yet available AFAIK.

Are diesel ignited engines, with compression reduction via head shimming a better fit or do these gasoline versions have variable compresssion system and a better option CPU. Sydney bus fleet are (originally) converted diesels, nowadays they buy OE NG ready by the hundreds.

not a hint of irony in goracles comment. Goracle after Al Gore.

SJC, If where you wanted to go was on well connected transit routes = better planning. If we didn't have the luxury of private 'carry me cause it's too far , forgot how to walk, can't ride a bike cause it's too dangerous or not facilitated, the sorts of problems everyone under licence age without well off indulgent parents that can't show the kids mobility, types or tie their own shoelaces cause you need a degree in magic knots that only a few can do, type. Well there would of course be an alternative. I suppose there are too any self interest individuals or square peg planners to see that we are the biggest problem here. The extra taxes are easily affordable by those with a higher percentage of disposable income. They are the ones that dont need to spend a high percentage of income on personal mobility. Australia has large distance low population density issues that dont easily fit mass transit options, America has legacy poor planning. Too much incentive or laziness assures the continuation of poor outcomes.

From practical horticultural experience and observation on this matter, I can say for sure that climax communities of the desired size can be cultivated in such situations. The land could be leased to interested farmer/ hort people and the best use as either firebreak, grazing, annual or biomass crop regimes implemented. They should be productive especially if supported by long favourable leases. It seems ridiculous to scorch more land when the productive potential is there in the win win low fruit category.

Enviro, "The best way to prevent war is through mutual dependence on trade. Corn ethanol has the effect of reducing corn exports, which has a similar pound for pound impact on trade deficits as oil imports." No problem there, happy to repeat it as it segways a point made recently that "green energy reduces wars." Renewable energy being made locally strengthens much including the economy and enables trade. Next: "A car with 10% ethanol reduces average oil use about 7%. A midsized four door hatchback Toyota hybrid reduces average oil use 100% (getting double the American average mileage)." I feel it is more correct to use 'pound for pound ' as studies have shown both fuel parity and other running cost benefits and savings from most ethanol mixes when engines are optimised to any degree as well as many clunkers that achieve benefits through better combustion. Hence better emissions. It is convenient and responsible to consider lb for lb. Public transport in theory benefits the entire community in many indirect and direct ways and is capable of raising living standards by more than one point. What would be most help is a bit of boosterintg or talking up and making fashionable the whole practice and understanding (promotion) of public transport use as a viable and agreeable option. The costs to private transport to any community include road infrastructure pollution and health medical and trauma, lost production from the disenfranchised that spreads through low support and underdevelopment of economical and better functioning of the public infrastructure.

Jeffa, Don't apologise for thinking you may offend, This is a no holds barred 'league of gentlemen' and ladies, Please feel ,free to aim low if you can see a way, they certainly call for it. I can only think it's their 'pleasure.'
