World Solar Challenge September 3 update

In the leadup to the 2019 Bridgestone World Solar Challenge in Australia this October, most cars have been revealed (see my recently updated illustrated list of teams), with JU’s reveal a few days ago (see below), and Tokai’s reveal due in a few hours.

There are now 9 international teams in Australia (more than the number of local teams). Eindhoven (#40), Agoria (#8), and part of Vattenfall (#3) are driving north to Darwin, while Top Dutch (#6) have a workshop in Port Augusta (and living quarters in Quorn).

The chart below shows progress in submitting compulsory design documents for the race. White numbers highlight eight teams with no visible car or no visible travel plans:

  • #86 Sphuran Industries Private Limited (Dyuti) – this team is probably not a serious entry. I will eat my hat if they turn up in Darwin.
  • #63 Alfaisal Solar Car Team – recently, they have gone rather quiet, but they have a working car.
  • #89 Estidamah – they have not responded to questions. They also might not turn up, although they have obtained several greens for compulsory documents.
  • #80 Beijing Institute of Technology – they never say much, but they always turn up in the end. I don’t expect this year to be any different.
  • #4 Antakari Solar Team – they are clearly behind schedule, but they are an experienced team. They will probably turn up.
  • #55 Mines Rabat Solar Team – they seem to have run out of time. Can they finish the car and raise money for air freight? I’m not sure. (edit: it seems that they will attend the Moroccan Solar Challenge instead of WSC)
  • #98 ATN Solar Car Team and #41 Australian National University  – these teams are obviously in trouble but, being Australian, they should still turn up in Darwin with a car.

World Solar Challenge late August update

In the leadup to the 2019 Bridgestone World Solar Challenge in Australia this October, most cars have been revealed (see my recently updated illustrated list of teams), and the first few international teams (#2 Michigan, #3 Vattenfall, #6 Top Dutch, #8 Agoria, and #40 Eindhoven) have arrived in Australia (see map above). Bochum (#11), Twente (#21), and Sonnenwagen Aachen (#70) are not far behind. Eindhoven (#40) are currently engaged in a slow drive north, while Top Dutch (#6) have a workshop in Port Augusta (and living quarters in Quorn).

Meanwhile, pre-race paperwork is being filled in, with Bochum (#11) and Twente (#21) almost complete. Sphuran Industries from India (#86) is not looking like a serious entrant. On a more positive note, though, Jönköping University Solar Team (#46) is revealing their car later today!


Solar car map of the Netherlands plus borderlands

Below (click to zoom) is a solar car map of the Netherlands (north, south, east, west), plus the German cities of Aachen & Bochum and the Belgian city of Leuven, which are close enough to the Dutch border to be in the map region. That’s 7 solar car teams in a very small corner of the world! (base map modified from one by Alphathon).

Yet another quick solar racing update

In recent solar car news, we have now seen new car reveals from several teams. The latest ones are shown above (click to zoom). Promised new car reveals include Vattenfall16 July, Michigan19 July, Stanford21 July, Aachen22 July, WSU7 August, Durham12 August, Cambridge15 August, EcoPhoton: some time in August, and JU30 August. I will continue updating my list of teams as news and pictures come in.


FSGP 2019 team photo – L to R from front: Kentucky, Illini, Esteban (Poly Montréal), W Mich / Florida, Principia, Calgary, SIUE / Northwestern, UPRM, Illinois St, Ga Tech / NCSU, Berkeley (CalSol), Mich St, Waterloo / NJIT, with Rutgers absent (credit)

Meanwhile, 18 teams – Kentucky, Florida, CalSol (1st in 2017), Northwestern, Mich St, Illinois St, Illini, Waterloo, Principia, Ga Tech, Esteban (3rd in 2017), SIUE, Calgary, Rutgers, NJIT, NCSU, W Mich, and UPRM – raced at FSGP 2019 on 1–6 July. Final results were as below (click to zoom):

The FSGP regulations give the score for multi-occupant vehicles (MOV) as S = (D / E) × C × T, where S is the total score, D is the Total Person-Mile Distance, E is the Total External Energy usage of the solar car, C is the Completion Factor, and T is the Target Speed Derate.

The chart below (click to zoom) visualises these scores on a logarithmic axis, with six coloured bars being components of the score, and the seventh coloured bar S being the product (and therefore the sum of the logarithms) of those components. The six components are:

  • d, the total miles driven
  • d, the total miles driven with penalties
  • p, the average number of persons in the car (and so D = d × p)
  • E, the total external energy usage (as in the regulations)
  • T, the target speed derate, which penalises cars slower than 27 mph (as in the regulations)
  • h, a grey bar (the same for every team) showing the highest driving distance of any MOV entry (and so C = d′ / h)

This version of the formula, S = d × d′ × p × (1/E) × T × (1/h), makes it clear that the distance driven is essentially being squared, and hence dominates the other factors:

It’s also worth mentioning the lap speed record that was set on the COTA track:


Another quick solar racing update


Four recently revealed vehicles: Top Dutch, Twente, Blue Sky (Toronto), and Kogakuin

In recent solar car news, we have now seen new car reveals from HUST (pic), Top Dutch (video), Twente (video), Blue Sky (video), the commercial solar car Lightyear One (video), Kogakuin (video), and – just now – Agoria (video and below).

Promised new car reveals include Eindhoven4 July, HK IVE6 July, NIT6 July, Vattenfall16 July, Michigan19 July, Aachen22 July, and JU30 August. I will continue updating my list of teams as news and pictures come in.


Esteban were first to get all greens in scrutineering for FSGP 2019

Meanwhile, 18 teams – Kentucky, Florida, CalSol (1st in 2017), Northwestern, Mich St, Illinois St, Illini, Waterloo, Principia, Ga Tech, Esteban (3rd in 2017), SIUE, Calgary, Rutgers, NJIT, NCSU, W Mich, and UPRM – are at FSGP 2019 right now. Esteban were first to get all greens!


2019 World Solar Challenge update #3

Warning: this list is obsolete. Please check more recent posts.

Here is yet another update on the 52 teams (27 Challengers, 24 Cruisers, and 1 Adventure car) aiming for the 2019 Bridgestone World Solar Challenge in Australia this coming October. Many teams are busy with construction, and below is my best understanding of the current team status. Meanwhile, 26 teams (Bridger, Calgary, CalSol, Esteban, Florida, Ga Tech, Illini, Illinois St, Kentucky, Mich St, Missouri S&T, NCSU, NJIT, Northwestern, Principia, PrISUm, Purdue, Rutgers, SIUE, UBC, UPRM, USC, UT, UVA, W Mich, and Waterloo), including 1 WSC team, are preparing to attend FSGP 2019 in America this July.

Several clickable social media links below have been corrected and some clickable YouTube and blog links have been added. I have also included some subjective traffic lights. The big news is that the Belgians are now called Agoria Solar Team (but fortunately their social media links aren’t changing), that Lodz Solar Team has produced a solar baby, and that Twente has revealed their design (a GaAs catamaran reminiscent of Nuna 9).

By special request, all links in this post (including the clickable social media icons) now open in a new tab or page, depending on your browser (I would welcome feedback on whether this is an improvement):
