(even WSC banned sprinkle water on solar cells which affected only Silicone teams) Harvesting from wide range of spectrum works far better than Si under cloudy weather.<br /><br />I totally don't understand why WSC increased the ratio for GaAs cells because they reduced it to make the chance for lower budget teams before. I doubt the just compared the catalogue spec (at 25 degrees) of both cells.<br /><br />If it applied to 2019, there is no change to win without paying more than $300,000 only for cells. It is the philosophy of WSC?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-58654821719114615562017-10-24T13:11:38.143-07:002017-10-24T13:11:38.143-07:00Wow, amazing work by the (extended) Kogakuin team....Wow, amazing work by the (extended) Kogakuin team. I know we expressed both our admiration for the beautiful and unique design and our concerns for the behavior in windy conditions. Sad still when it actually happens. Good the driver wasn't (physically) hurt. Next time with a smaller MJ-based Wing they may be doing much better on speed and safety.<br /><br />ErikAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-23244717548070957472017-10-24T08:10:28.991-07:002017-10-24T08:10:28.991-07:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-72157046135543627412017-10-24T06:52:27.759-07:002017-10-24T06:52:27.759-07:00I guess the video from Kogakuin puts their perform...I guess the video from Kogakuin puts their performance into perspective.<br /><br />Nice ending though.<br /><br />NigelAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-38291901395208255672017-10-22T19:07:11.445-07:002017-10-22T19:07:11.445-07:00Dietrich: Perhaps if the race had been hotter and ...Dietrich: Perhaps if the race had been hotter and faster, the GaAs cells would have had a larger advantage. I'm not sure if WSC should reduce the area of the GaAs cells at all - if there's clearly a disadvantage, no one will use them (see 2011-2015), so why even bother allowing them in the first place?<br /><br />Agreed that the low proportion of solar energy on the Cruisers is lamentable - it would be nice if they were allowed big 8sqm solar arrays (like the single-seat cars were back in 2005 and earlier). Eindhoven could have done the entire course on solar with an 8-10sqm array.<br /><br />Everyone's been complaining about how practicality judging is a mystery since the first Cruiser regs were issued in 2012, but WSC seems to delight in keeping it a secret. I hear teams complaining every year, but they keep coming back...mostdecehttps://www.blogger.com/profile/17817140290262571411noreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-54466347728587983282017-10-22T07:09:37.046-07:002017-10-22T07:09:37.046-07:00Thank you for your wrap up.
I agree that challenge...Thank you for your wrap up.<br />I agree that challenger class was exciting this year. However, I'm not sure whether the use of GaAs-Cells is really no advantage. With more heat there could have been even more dominance of the multijunction cells. I think there should always be a slight disadvantage to use them, because only the best teams can afford these cells.<br /><br />For the cruiser class there is indeed a great chance to improve regulations. Nevertheless this years competition also had some good ideas: The objective to organize a race for efficiency has been a clue to be able to compare different solar cruisers. Although it is sad, that the cruiser class didn't use a lot solar energy. In my opinion the regs for the cruiser should not allow loading from the grid at all (or at least it should be treated like trailering). Instead the solar cruiser could be allowed to carry up to 2(?)m² extra array in the car for loading during stops. Practicality should be fun or be predictable (storage space/passenger or predefined set of boxes where the basis is always 2 Passenger). Of course 18 Minutes should not drop the efficience score to zero in 2019 but there could just an efficiency factor that makes it less attractive to drive slower than Friday 2 p.m. <br />I'm looking forward to cruiser class in 2019!<br />Dietrich<br />Dietrichhttp://www.perpetu-blog.denoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-84096012040166920842017-10-22T03:21:04.921-07:002017-10-22T03:21:04.921-07:00That makes sense, IF you usually take a baby to wo...That makes sense, IF you usually take a baby to work with you.<br /><br />On that point, I was surprised that Tafe did not use a bench seat in their Yute.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-62862842170497785862017-10-21T17:16:22.420-07:002017-10-21T17:16:22.420-07:00I believe TAFE used seats that were unable to fit ...I believe TAFE used seats that were unable to fit the child car seat, which is how they got a point off for storage.mostdecehttps://www.blogger.com/profile/17817140290262571411noreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-14160807339462063922017-10-21T17:04:30.967-07:002017-10-21T17:04:30.967-07:00I've been a huge fan of the Cruiser class sinc...I've been a huge fan of the Cruiser class since it began in 2013 but the further we get the more obvious it becomes that WSC do not know quite what to do with it.<br /><br />It is plain that the panel that fixes the rules see 4+ seat cars as the most practical. I have always found this strange since, if you look at any survey of traffic journeys, it is clear that the average occupancy of a car is nearer to 1 person than 2.<br /><br />Then again there is the juxtaposition that teams are asked to design cars to suit real life, and then tested in a way that is about as far removed from everyday life as is possible.<br /><br />Even when we come to energy efficiency there is the awkward problem that the winning team(brilliant as they were), in real life, would have dumped all of its passengers halfway through the journey in order to reach the destination on time. Hardly practical!<br />If a competition element(a BIG if, I believe) is to be maintained in the future I think that performance against capacity should be measured.<br /><br />I fully agree with your comments regarding the practicality marking and indeed it seems that one aspect of a car, its size, is rewarded time and again throughout the competition.<br /><br />That said, I was astounded to see that the Tafe car managed to score less than maximum points for its storage capacity, how the hell did that happen?<br /><br />I am thankful that teams seem mostly to disregard the rulebook, in terms of winning I mean, and just make the car they want to make. After all, as we've hinted before, a good Challenger type car with a dummy second seat and a 5kwh battery could have recharged in Alice and still won the competition by a distance.<br /><br />I really hope that the class continues in the future but I'm starting to feel that it's time to stop trying to compare such disparate entries.<br /><br />NigelAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9033006010530873827.post-55163319017517975352017-10-21T17:03:42.630-07:002017-10-21T17:03:42.630-07:00Totally agree with your Cruiser criticisms.
