Solar Panels

Solar Panels

Here Comes The Sun: These solar panels capture light and heat from the sun to power exhibits when I’m out visiting around town.

Tailpipe Area

Tailpipe Area

No tailpipe, no fumes. That’s how I roll.

Plug

Plug

Not An Ordinary Plug: Big trucks need more energy. To get all the energy I need, I have to have a bigger plug and a special outlet!

Wind Turbines

Wind Turbines

Wonder of Wind: Wind turns these turbines and generates electricity. The output from two average wind farm turbines is enough electricity to power 924 average American homes for a year!

Brakes

Brakes

Brakes 2.0: My brakes recapture energy that would otherwise be lost as heat, helping keep my batteries charged and ready.

Turbine

Turbine

Spin Me Round: In a power plant, these make my energy. Moving water or steam spins these to produce electrical energy I need for my batteries.

Motor

Motor

Here’s my motor! It uses electricity to turn my wheels.

Atom

Atom

Making and Breaking Atoms: Putting atoms together (fusion) or taking them apart (fission) releases energy. This is called nuclear energy.

BioFuels

Biofuels

Bountiful Biofuels: Algae, corn, sunflowers… biofuels can be made from a plethora of plant sources.

Sun

Sun

The sun is the source of all the Earth’s energy.

EVie is an electric truck from Smith Electric Vehicles that has been modified.  EVie is a 24,000 box truck full of exhibits and other things to help you learn about energy, electric vehicles and the environment.  Instead of an engine, EVie has a 160 hp or 120 kW induction motor with a top speed of 50 mph!  EVie has 2 pods of batteries that supply her with 80 kWh of electricity to run the motor.  When EVie’s batteries are fully charged, she can go about 100 miles.  EVie’s batteries are lithium-ion phosphate that can take up to 8 hours to charge.

EVie’s had some modifications done to her as well.  Besides really spiffy graphics that shows how energy flows from natural sources to industrial uses, EVie has solar panels on her roof and on her back.  These solar panels power all of EVie’s exhibits.  She has 9 solar panels on the roof and two solar panels on the back.  The two panels in the back are transparent!  The neat thing about them is that they can make electricity when the Sun hits the top or the bottom!

EVie has canopies to shade all of her exhibits.  Monitors are built into her sides allowing you to watch movies starring EVie!

EVie is a very special truck!  Come on down to the St. Louis Science Center and meet her!
