I guess Barbie mastered those tough math classes

Remember Teen Talk Barbie that caused a women’s rights uproar when it uttered the phrase, “Math is tough?”

Well, times have changed, and now even Barbie has loftier career goals, as demonstrated by Mattel’s new “I Can Be…” Architect Barbie.

In honor of the new doll, the American Institute of Architects hosted a competition, asking architects and designers to come up with Architect Barbie’s new Dream House — and the winning design was refreshingly eco-friendly.

The Dream House, which is certified by the U.S. Green Building Council, boasts solar panels, a living roof, bamboo flooring, low-flow toilets and sinks, and energy-efficient lighting and appliances.

The Malibu home doesn’t have a garage for a gas-guzzling car; it only offers a small parking spot for Barbie’s scooter.

However, the size of the green Dream House — 4,900 square foot — isn’t very environmentally responsible.

I wonder what Architect Barbie would think of this Malibu home built out of a junked 474 aircraft…

Looking for something to do in downtown San Jose on a Saturday?

This Saturday, I was melting in the heat of downtown San Jose, killing time before a friend’s wedding when I happened upon the City of San Jose’s Clean Energy Showcase.  Open to the public for free every Saturday from 9 a.m. to 1 p.m., the showcase features the latest in green technology — solar, solar hot waters, wind turbines, electric vehicles and more.

Here’s a preview of what you’ll find:

Plug-in hybrid with a solar charger

Solar hot water heater

Solar oven

DIY: Recycling an old pizza box into an oven to reheat your pizza with solar energy

Fancy schmancy solar panels

Attic insulation made from old blue jeans

Inside the zero-energy cottage

The zero-energy cottage, complete with native, low-water landscaping

Solar energy collector

Solar film panels that can be printed!

Coolest street light ever — its LED light is powered by the sun or wind, depending on weather conditions

Solar hot water - saw these on nearly every roof during my trip to Israel and Greece last year

Adorable EV

This ri-donk-uclous pink SUV limo for a quinceanera was parked across the street from the Clean Energy Showcase - a bit of a juxtaposition, no?
