… and they didn’t have the awesome @RealPeerReview back then.
Australia is waiting for contestants in the 2017 World Solar Challenge, the premier world contest in sustainable vehicle technology. The average maximum October temperature in the town of Katherine, on the Stuart Highway, is 37.7°C. Road trains are a frequent hazard on the highway, and past races have had to deal with fire as well. Sometimes things go wrong with the car. But it’s still an absolutely fantastic experience!
The chart above shows car weights (in kg) for the World Solar Challenge Challenger class, since 2001. In spite of the increasing safety standards and the shift from 3 wheels to 4, weights have trended steadily downwards, which says something about the strength-to-weight ratio of modern composite materials.
For the WSC Challenger class, this is not a difficult question. Nuon Solar Team owns the race, and has won six times out of eight this century (although “uneasy lies the head that wears a crown”). The more interesting question is: who is second? There are four main contenders for that honour.
A few years ago, I would have placed Tokai University second. They won the race in 2009 and 2011. However, unless they can reverse the trend, their star seems to be falling.
Michigan are very definitely the best US team. However, they have pointed out themselves that they suffer “the curse of third,” and thus far lack the je ne sais quoi that it takes to win (of course, when they find it, Nuon had better watch out).
The star of Solar Team Twente is rising. They worked their way up to second place in 2015. They could win this year.
Finally, the Belgian team from KU Leuven is also moving up, and I expect them to do very well this year also.
Lately I’ve been exploring demographic and social data, including looking at the Australian data in the World Values Survey. Of particular interest are data on self-reported happiness. Among women, financial stress and poor health contribute to unhappiness, as might be expected. Socially conservative women report being happier, and single women report being less happy. Finally, women who attend religious services once per week or once per month are happier than those who do not attend religious services, or those who attend religious services more than once per week. This is broadly consistent with literature on the effects of religion on mental health.
Among men, financial stress and poor health act in the same way as for women. In terms of marital status, however, it is separated men who are the least happy. Male happiness is also closely tied to employment status, with unemployed (and, to a lesser extent, self-employed) men reporting more unhappiness.
Lately I’ve been exploring demographic data related to women’s health. Among other things, this involved looking at the Australian data in the World Values Survey, which includes a self-reported measure of health. For women, this depends on a number of other variables, including age:
For men, the age effect is weaker:
Presumably, this is because male health problems are more likely to be fatal, which is why there is an excess of women amongst the elderly, as indicated by Australian census data:
