The Future of Cars

I created a spreadsheet for you to claim your research topic on The Future of Cars

https://docs.google.com/spreadsheets/d/1ekJhMnF6rQyR5PsIRH-RAIt6KQbNjkeXKk_WW_e9op0/edit#gid=0

Feel free to add your own topic if you don’t see one you like. I would like you to research the topic and be able to explain it to us. Think about the who, what, when, where, why, and how of your topic. The list I came up with includes:

  • Flying cars
  • Hydrogen fuel cells to power cars
  • Autonomous driving cars
  • LiDAR in cars
  • Stirling Engine
  • Connected cars (networked with other cars to avoic accidents, efficient traffic)
  • Cars made of carbon fibre, plastic, composite materials for light weight
  • Customized/individualized cars with new manufacturing techniques (3D printing, etc)
  • Smart cities and smart roads

Feel free to add your own topic to the spreadsheet if you don’t like one of these. Oh, and please do your research before class instead of while class is going on.

How do cars work?

How does an internal combustion engine work?

Explain what these things do:  Cylinders, valves (inlet and outlet), pistons, carburetors (fuel injectors), sparkplug, crankshaft, gearbox.

Explain what this means: 5.21 liter V8 Engine producing 526 HP and 429 lb/ft of torque

How does an electric motor work?

Explain: Rotor, stator, brushes. Induction motor vs permanent magnet motor

How does a hybrid car work?

 

Cars: Your Dream Car


For the first class, I would like you to come prepared to present your dream car (or maybe just a car that is interesting, intriguing, exciting, etc.) Be ready to share some pictures/videos and some facts about the car. Also be prepared to talk about why you selected this particular car.

Make
Crème Brûlée Adapted from Epicurious Food (food.epicurious.com)
Ingredients:
For Custard:
• 2 cups whipping cream
• 1/2 cup sugar
• 1 vanilla bean, split lengthwise
• 5 large egg yolks

For Crème Brûlée
• 12 teaspoons sugar

Method:

Making custard
• Preheat oven to 325 F.
• Mix cream and sugar in heavy medium saucepan.
• Using small sharp knife, scrape seeds from vanilla bean. Add seeds and bean to saucepan.
• Stir over medium heat until sugar dissolves and mixture comes to simmer.
• Cover pan, reduce heat to very low and simmer gently 10 minutes to infuse flavors
• Strain into large measuring cup
• Whisk yolks in medium bowl until well blended. Gradually whisk in hot cream mixture just to blend.
• Return custard to measuring cup
• Divide among ramekins
• Pour enough hot water into pan to come halfway up sides of ramekins
• Carefully transfer pan to oven
• Bake custards until almost set in center when gently shaken, about 35 minutes.
• Let cool 30 minutes
• Chill at least 3 hours and up to 2 days

Making Crème Brûlée
• Sprinkle 2 teaspoons sugar evenly over each custard.
• Working with 1 custard at a time, hold blowtorch so that flame is 2 inches above surface.
• Direct flame so that sugar melts and browns, about 2 minutes
• Refrigerate until custards are firm again but topping is still brittle, at least 2 hours, but no longer than 4 hours so that topping does not soften
• You can garnish crème brûlée with fruit
