New Year

Jason Benz — Sat, 31 Dec 2022 13:01:58 +0000

Happy New Year 2023. Given recent history, Good Luck is probably a more appropriate greeting. Instead of my standard firework/gig new year post, I have created a homage to Banksy.

No internet available, so original photography was used. The German Leopard tank was outside a military base in Australia. The wall is from Egypt where bricks are so worn, they almost look like sandbags. Finally I photographed a cereal box to get the recycling logo.

Final Parade

Jason Benz — Sun, 20 Oct 2019 05:13:54 +0000

This is the Cambridge University Eco Racing teams car, Helia, leaving the centre of Adelaide a few moments ago for the final parade of the Bridgestone World Solar Challenge. It has been an epic race of 3000km from Darwin in the Northern Territory to Adelaide in South Australia. It has been an honour to share the road with these amazing solar-powered cars and to meet the teams along the way. Their engineering and imagination have been awe-inspiring.

I will be continuing my journey east to the Blue Mountains but not before I have caught up on a week of sleep.

Solar Ute

Jason Benz — Sat, 19 Oct 2019 10:02:31 +0000

This Solar Ute is the most unique vehicle at the Bridgestone World Solar Challenge. I arrived in Adelaide just after the last team crossed the finish line. Fortunately, the lovely people from Tafe SA were good enough to give their car a push so I could get this photo. When leaving Darwin this prime mover was attached to a 7-metre trailer with 14 square metres of solar cells which provides an extra 2.8kw of power to the Ute. Weighing in at 1.4 tonnes it is the heaviest and longest solar automobile. The team overcame many hurdles to get here. During track testing, they blew up one of the motor controllers so the 11.5-metre articulated vehicle was being pulled by just one wheel. This created so much heat that during the race they built an ingenious cooling system with a CO2 fire extinguisher.

I have a few repairs of my own to do on the van before heading back to the Blue Mountains.

Hover Car

Jason Benz — Thu, 17 Oct 2019 11:01:49 +0000

This beautiful machine which appears to hover is called Violet, A solar powered cruiser from the Sunswift team, based at the University of New South Wales. The Cruiser class of vehicles have much more variety in design than the speedy Challenger class which are generally either asymmetric catamarans of mono hulled bullets.

I photographed this solar car earlier today leaving the Glendambo control stop, which is the 8th of 9 compulsory half-hour stops between Darwin an Adelaide on the Bridgestone World Solar Challenge.

Tomorrow they will be the first Cruiser to cross finish line. However, the first Challenger already crossed the line today in a time of 34 hours, 52 minutes, 42 seconds. Less than 3 minutes separated the two lead cars during the final leg when the reigning champions caught fire leaving Belgiums BluePoint to claim their first title.

Cruiser Charging

Jason Benz — Wed, 16 Oct 2019 11:52:03 +0000

This amazing looking car is named Priscilla and was put together by the Australian Technology Network, which is a collaboration between five universities in Victoria, New South Wales, South Australia, Queensland and Western Australia. This makes it Australia’s only national team. It arrived in Coober Pedy today at the 2nd charging station for the Bridgestone World Solar Challenge. The Cruiser class of solar cars are allowed two charging stops between Darwin and Adelaide. Whereas the Challenger class cars do the whole 3000km with only the power of the sun they collect en route. I met the designer of the body today who is also a mechanic. He offered to tune up the engine in my van as he could hear it was struggling to keep up with the solar cars.

Solar Swedes

Jason Benz — Tue, 15 Oct 2019 12:42:18 +0000

In what is becoming a common sight on the Stuart Highway in Australia, teams in the Bridgestone World Solar Challenge tilt their solar panels towards the sun to get the last few drops of energy into the batteries ahead of tomorrow’s day of racing. This is Jonkoping University Solar Team with their solar car Axelent. They are the only Swedish team left in the race from the four that started. They are hoping to improve on the 8th place they achieved in the last race. Behind them is the Japanese team Nitech Solar Racing with their car Horizon Ace who also just passed the halfway point south of Alice Springs at the end of the 3rd day of racing.

Tomorrow I will pass the turnoff to Uluru (ayers rock). Along with the Sydney Opera House it cannot be used for commercial stock photography. However, it is currently a newsworthy event which qualifies it as editorial photography. The reason is, in 11 days the rock will be closed to climbers permanently. As the deadline approaches the number of climbers has increased dramatically. This has resulted in even more visitors relieving themselves on what is a sacred site to the traditional owners (the Anangu people). It would be difficult to fit in a 525km detour in the middle of a race, so visiting Ularu will have to wait until it is not crawling with bogans.

Champion Cruisers

Jason Benz — Mon, 14 Oct 2019 06:51:13 +0000

This is Stella Era from Solar Team Eindhoven who are the reigning champions in the Cruiser Class of solar cars in the Bridgestone World Solar Challenge. Unlike the Challenger Class, which is all about speed. The Cruiser Class provides a platform where ideas can be tested for their practicality and commercialisation. This car, for example, not only seats 4 people, the battery has a 1800km range, and it can sense if it is parked in the shade and automatically move itself into the sun to charge. Despite its size, this is no slow coach, It currently leads the Cruisers and many of the Challengers too.

Race Begins

Jason Benz — Sun, 13 Oct 2019 11:09:14 +0000

Today saw the start of the 2019 Bridgestone World Solar Challenge. After a discussion with the Benz World Blog readership, and given my van is older than most of the contestants, I decided to get a head start. I left Darwin 30min before the start and 15mins down the road. It was just enough to spread out the field and support cars. 1 hour and 80km from the start I was overtaken by my first solar car, BluePoint from Belgium closely followed by RED E from the Netherlands. This is exactly as they appeared in the prophetic Track Testing post. Next was Top Dutch Solar who started in pole position. Then this car from Kogakuin University Solar Team with their car KUTE Eagle. Their car, whose shape is based on the beak of a bird also has a unique air-oil suspension. Unlike most teams who have prioritised aerodynamics over power, this Japanese team have built a tilting panel which can maximise the power from the sun. Unfortunately, their motor blow out just after the first control stop in Katherine giving them 1hr of roadside repairs. In what must be one of the races outstanding performances they rejoined the top quarter of the field at the second control stop in Daly Waters with 2 minutes to spare.

Line Up

Jason Benz — Sat, 12 Oct 2019 07:56:45 +0000

These are the competitors for the 2019 Bridgestone World Solar Challenge. I spent the day watching teams complete their hot lap to secure their place on the start line tomorrow. Debutante team Top Dutch Solar Racing (on far left) got pole position with their car Green Lighting in a time of 1:51:99 (92.3km/h)

I had been trying to get a photo of the Cambridge University solar car all week. The hot lap would be my best chance so far. Unfortunately, they ran out of time and could not record a lap. Hopefully, the race will go better for them as they are yet to finish a Solar Challenge.

I was surprised not to see more UK university teams as the challenge is perfectly suited to any engineering department. Especially as the development of this technology is essential if humans wish to continue living on this planet. My own experience studying engineering in UK did find some of the lectures had a Brunellian approach to all design. This is fine if you are making bridges from cast iron but of no use when it comes to lightweight efficient designs. Fortunately, the rest of the world has stepped up to the challenge with teams from Thailand, Chile, Poland and Morocco. Japan even has a high school team.

Track Testing

Jason Benz — Thu, 10 Oct 2019 08:46:05 +0000

This is BluePoint from Belgium at the Hidden Valley test track for the Bridgestone World Solar Challenge. The Agoria Solar Team, designed and produced their own solar panel for the event and hired professional Nascar driver, Bert Longin to take the wheel.

Behind their car is RED E from the Netherlands who have the smallest car at the event. The Solar Team Twente have decided to use a shingled GaAs solar panel.

The event attracts designs with all the variety of the Wacky Races. However, at the top end of the hyper-efficient Challenger Class the shape of the solar cars show a degree at convergence as an asymmetric catamaran style with a single powered wheel under the driver proves to be consistently hard design to beat.

The Dynamic Scrutineering starts on the 12th October before the race starts on the 13th.

UPDATE: BluePoint went on to win the race in 2019
