Fans in the stands

Racing electric vehicles has been a constant evolution since their invention 100 years ago and solving challenges related to range, speed and quick battery swaps are all within reach towards creating a vehicle that can compete against a current Indy Car. However, if the race does not provide the visceral experience of hearing  and feeling the noise of 20 highly tuned Indy Car engines hurtling down the front straight, there is little chance of atracting fans to the stands, to witness (read: fund) the event.

Beth, Data Acquisition has been around for decades on race cars. Telemetry is cheap enough today, that even lower classes of racing are using it. If you want to know more about these electronics, you can go to http://www.cosworth.com/Default.aspx?id=1094933 The data is used to make the car and driver faster. Think about shift points, braking points, slower drivers not using full throttle either due to poor car setup or lack of confidence in the car.

Electric Indy, I doubt that the fans will show up for a race where the cars are so quiet that you can't hear them. The sound of an electric motor whining around the track does not get the adrenaline going. Interesting - Yes, Exhilarating - No.

Ivan: Yes...Parnelli Jones' turbine car ran at Indy in 1968. The technology was quickly legislated out of future races. And you're right, Indy is all about rules, rules, rules, so an electric car would face a mountain of obstacles. I think you're onto something, though. What about an ALL-electric Indy race, where cars pull into the pits every 40 miles or so and use fast-battery-swap technology to install new sets of batteries? Sure, the cars would be slower than today's Indy cars, but maybe not as much slower as we might initially believe. Look this up: The White Lightning all-electric car actually ran at speeds of 240 mph. Maybe the race would have to be shortened, but it can be done. You may have launched a movement here, Ivan.

An all electric Indy racer?

Anyone care to opine on just when and under what conditions we might find an all electric Indy race car?  It might take some creative interpretations of the rules or some edits but I am willing to bet it will not be too long before an all electric car is entered.  

I recall the turbine driven entry froma  while back that almost won.  That prompted some rule changes and I don't think we have seen one since.  

It would definitely mark a turning point in the storied history of Indy racing!

It was surprising to see the BMW crew at the helm of so many real-time data feeds and screens. What exactly is the data being fed to the pit crew and any sense of how it's transmitted?

My guess is the next step in the techie transformation of the pit crew will be to replace those semi-dated looking screens with some fancy, touch screen tablets.

The shots of the screens tracking the BMW were surprising. I didn't realize techy communications had moved so deeply into the racing world.

I'm now kicking myself for not bringing my Nikon SLR along for that leg of the trip! But the iPhone 4 does a creditable job capturing still and video. 

Thanks for posting this. We got a chance to talk with Jay O'Connell, Bobby Rahal's chief engineer and he gave us a sense for the amazing communication that goes on in real time between the cars and the pit crew during the race (and which shows up graphically on their computing screens as what they call "marching ants" as the cars zoom around the track!). 

Here's a link to our post about how O'Connell and team are so good at what they do, that race series organizers have put a governor on their cars!

Latest Analysis
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
