  3. Re:Renewable or infinite? on The Myth of Renewable Energy · · Score: 1

    A friend had Toyota Camry that got hit with what would have been minor damage. The insurance company would have written it off but had no information about how much it costs to get repairs done one these. It turns out they spent about half the cars new price on getting it fixed and they didn't even replace the rear bumper cover. If those costs don't come way down, the insurance prices is going to go way up meaning there is even less incentive to buy a hybrid or insure one. Once cars stop being insurable their value drops quickly and they tend to get scrapped. I'm sure there will be a few home mechanics who want to rebuild hybrids but right now the costs of that seem like they will exceed the costs of buying a new car.

  5. You don't want 100% compliance on Multi-Target Photo-Radar System To Make Speeding Riskier · · Score: 2

    Victoria Australia has 99+%* speed limit compliance on some highways and its accident count has been steady for a while and the deaths per distance driver has increased in step with the speed limit compliance. This year was on track for being worse than last year except the police decided to stop writing tickets as a protest for more money which resulted in an increase in speed and a drop in the accident rate.

    They run a "Wipe off five" ads here which came from badly done report on crash rates out of South Australia university* that forget to take into account increased traffic density increasing accident rates. They claim by going just 5 km/h over the limit doubles the chance of an accident*. What they don't say is that is true for about 25 km/hr over the limit (as per Solomon quoted elsewhere here). They didn't point out that slowing down everyone increase tail gating which is something like 4000 times more likely to cause a death*.

    Of course using traffic from Adelaide for any other city is like using traffic data from Billings Montana for Los Angles, Rome or Cairo.

    Victoria currently has about 350 people a year die in traffic accidents*. World wide trends in stats show that number is somewhere between 20 and 100 high than it should be*. I figure the "wipe off five" campaign is killing an extra 30 people a year.

    They use the distance over time cameras between Sydney and Melbourne in Victoria and have for years. The police stopped counting a number of single victim accidents in the road stats as well. Apparently stressing out drivers so bad they have a stroke and kill other people doesn't count as a "road accident" anymore since it was a "medical problem"

    * data can be found on VicRoad's annual reports and crashstats web sites and backed up references found in a wonderful bit of fiction published by the Victorian Auditor-General.

  7. Re:6 cents on US Funds Aggressive Tech To Cut Solar Power Costs · · Score: 2

    Around here you get about 4 kwh per day on a 1 kW set of panels. That may last about 25 years before it drops below 80% of it's current efficiency. That means over the useful life of the system you are looking at 36500 kwh for a cost of about $2k or about $.054 per kWh until you figure in the time value of money and as well as the costs of the inverter and other extras. If you figure in power currently costing about $.20/kWh then solar does make sense as long as energy increases at inflation levers or higher.

    Call their office and ask if they have ever sung "Happy Birthday" in public and did they pay the royalties. If they were in the Senate in 2001, ask if they asked for permission to sing a copyrighted song before they sang it on the steps of the Capital. This works much better if you can ask a Senator in public.

    The accident stats are in VicRoads annual report where the accident rate per km driven is very interesting as it climbs every year. There is that lovely report on the Auditor General's report which cites a report from the Cochrane Library that has all the details about speed limit compliance and links to other sources of that info.

  11. Re:A comment from a recent repatriated Canberran on Canberra Police Want Drones To Track Cars · · Score: 1

    You won't get zero deaths on a road because it is a common yet underreported method for suicide.

    A traffic group in South Australia published a paper that said you double the accident rate for every 5 km increase in speed and that became the basis for traffic safety programs in Victoria and NSW. That report didn't take into account traffic density but since they are in a sleepy town of Adelaide, maybe it was beyond their comprehension that as you slow down traffic, you increase its density in odd ways that will lead to more accidents. The report has a few other problem like using data from other places were speed limits aren't hard limits but recommended maximum speed and not labelling their axis. A report cited in an Auditor General's report described the science in that study as poor. If you go back to their source data it appears that they were talking about risk of an accident at 25 km over the limit is half of that at 30 km over the limit but driving 25 km over the limit is about 4000 times safer than following less than 3 seconds. I suspect the dependence on that report to set policy has killed somewhere between 30 and 100 Victorians every year for the last decade.

  15. Re:Altitude is your friend on James Gosling Report of Reno Air Crash · · Score: 1

    I expect that plane was modified to run that race which means its neutral trim position would be for the high speed part of the course which would imply that not having it wouldn't have much effect. However the effect when it came off could feel like an aileron problem by inducing a bank and some odd yawing. If that banking was countered and then the trim tab went away, it would help explain the barrel roll. The P-51 also has wide elevator deflection range and it looks neutral in some of the pictures and I would have expected it to be full up if the pilot had any choice. The tail wheel being out is evidence for some unusual forces on the tail of the plane. On a stock P-51, the tail wheel can be extended and doing a high G climb once the lock is released.

    The climate of part of the dustbowl was changed by planting trees to control wind and creating many new lakes which changed the local water cycle enough to change the types of plants that now grow in the area. Changing the local water cycle was known even before the mis-guided concept that "rain follows the plow" which was based on the incorrect assumption that as you managed land by farming, it would increase the local rain. They missed out on the bit where they need local sources of water like man made lakes.

    I expect some of the inland salt lakes in Australia will end up flooded as a way to get more rain into the south eastern part of the country. Some of the lakes are below sea level were they could be easily flooded.

    It is amazing how much it costs to deal with cash and how much more it cost to deal with coins. Australia has one and two dollar coins which are heavy, bulky coins. There are rumours that many banks keep a large part of "cash reserve" as coins in containers since they can't afford to ship them around and its cheaper to order new coins at the government's expense. A common sight in banks around closing time is the people who run restaurants going to collect brick sized packets of coins for change. The major stores like K-mart have two armoured car deliveries, one for the coins and one for the notes. Now you have to fee parking meters with $2 coins and its not uncommon to see $16/hr meters (run by the same group who is trying it in Chicago but with quarters). I can't see how the $1 and $2 coins are beneficial to anyone once you figure in the transport cost of the longer lasting coin. The average age of the notes I currently have is older than the average age of the coins and many of the $2 coins are so beat up they won't work in vending machine.
