Our Built Environment: It Takes Energy

submitted by: nsf

Can we rethink the way buildings use energy? John Ochsendorf, an Associate Professor of Civil and Environmental Engineering and Architecture at MIT, is working with his students to change the way buildings are made and how they consume energy.

If you had the right tool kit, what would you make? If you take even a glance around the Center for Bits and Atoms at the Massachusetts Institute of Technology (MIT) in Cambridge, Mass., you can't help but notice--there seems to be a "bit" of everything, everywhere. But once you get past the bicycle tire hanging from the ceiling, the stacked book shelves and desks, a large tank of water, and a variety of electronic circuit boards, you'll find a small tool shop. And this is where our story...

GREEN REVOLUTION: HYDROGEN

submitted by: nsf
Host Lisa Van Pay meets with NSF-funded scientists Yang-Shao Horn and Yogi Surendranath at the Massachusetts Institute of Technology as they take on the hydrogen energy challenge. Hydrogen bonds are an extremely efficient way to store energy, and scientists would like to capture this energy to power all sorts of things—from cars to laptops. Unlike other fuel sources, hydrogen can’t be harvested easily, so we have to make it. From the importance of developing an effective catalyst to...

GREEN REVOLUTION: ELECTRIC VEHICLES

submitted by: nsf
Host Lisa Van Pay visits the scientists and engineers working to make the electric car of the future a reality today. One of the toughest parts is storing enough potential energy to get you where you’re going, and in this case, it’s all about the battery. Graduate student Katharine Stroukoff from the University of Texas-Austin explains how her research may help build a better battery, while Mike Nawrot and Dan Lauber, members of the MIT electric vehicle team, describe the advantages of...

GREEN REVOLUTION: CITYCAR

submitted by: nsf
Lisa Van Pay of the National Science Foundation meets with Will Lark, an MIT graduate student working on the CityCar project. The two discuss the technologies that make this vehicle unique and explore the relationship between art, science, and design. The CityCar team hopes that their ideas will some day be part of the solution to problems common to many cities: pollution, traffic and lack of green space. This story allows the viewer to see how researchers identify problems, build models to...

EINSTEIN'S MESSENGERS, LIGO AND THE SEARCH FOR GRAVITY WAVES

submitted by: nsf
Einstein's Messengers is an Award-winning 20-minute documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory. The video examines how LIGO is spearheading the completely new field of gravitational wave astronomy and opening a whole new window on the universe. It explains how LIGO's exquisitely sensitive instruments may ultimately take us farther back in time than we've ever been, catching, perhaps, the first murmurs of the universe in formation. Above all, Einstein's...

Tunable Photonic Gels

submitted by: GloucesterHigh-APchem
This demonstration illustrates physics, chemistry and engineering to all grade levels, from kindergarten through high school. Elementary students gain observation skills. Middle school students learn about elements, compounds, and mixtures plus physical and chemical changes. High school students gain knowledge of a variety of chemistry and physics features such as redox, chemical bonding, motion and forces and wavelengths.The hydrophobic block-hydrophilic polyelectrolyte block polymer gel...

The Leveraged Freedom Chair: a developing country wheelchair

submitted by: awinter@mit.edu
The purpose of the Leveraged Freedom Chair (LFC) project is to create a mobility aid specifically for developing countries. Conventional western-styled wheelchairs are nearly impossible to propel on the sandy roads and muddy walking paths frequently encountered in the developing world. The LFC has a variable mechanical advantage lever drivetrain that enables its user to travel 10-20% faster on tarmac than a conventional wheelchair, and off road like no other mobility aid available. The user...
