What Is the Future of Wind Energy?

04-21-22

Humans have used windmills to capture the force of the wind as mechanical energy for more than 1,300 years. Unlike early windmills, however, modern wind turbines use generators and other components to convert energy from the spinning blades into a smooth flow of AC electricity. In this video, John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering discusses the future of wind energy technology. [Caltech story]

Student-Led Lunar Architecture Team Named Finalist in NASA Competition for Second Consecutive Year

04-12-22

Caused by collisions from asteroids, comets, and other astronomical objects, lunar craters give our moon its characteristic pockmarked façade. These craters hold the materials necessary for building sustained human settlements on the moon. Accessing the materials inside lunar craters is no easy task. NASA seeks new ways of getting around the moon that do not rely on wheels. The agency's Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge asks university teams to go beyond wheeled rovers and create new solutions to the problem of traversing lunar craters. A team of more than 30 Caltech undergraduates in the Division of Engineering and Applied Science is among seven 2022 BIG Idea finalists. [Caltech story]

Gunnarson and Dabiri Teach AI to Navigate Ocean with Minimal Energy

12-09-21

Engineers at Caltech, ETH Zurich, and Harvard are developing an artificial intelligence (AI) that will allow autonomous drones to use ocean currents to aid their navigation, rather than fighting their way through them. "When we want robots to explore the deep ocean, especially in swarms, it's almost impossible to control them with a joystick from 20,000 feet away at the surface. We also can't feed them data about the local ocean currents they need to navigate because we can't detect them from the surface. Instead, at a certain point we need ocean-borne drones to be able to make decisions about how to move for themselves," says John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering.

Dabiri Appointed to Secretary of Energy Advisory Board

10-15-21

The Department of Energy (DOE) has announced that John O. Dabiri, the Centennial Professor of Aeronautics and Mechanical Engineering, has been appointed to the Secretary of Energy Advisory Board (SEAB). The SEAB meets quarterly to advise Secretary of Energy Jennifer Granholm on how best to achieve the department's priorities and offer recommendations on scientific, technical, and programmatic issues relating to the DOE's mission. "I'm excited to work with the secretary to ensure strong support for fundamental science research, especially in areas where the technological application might be hard to predict today," Dabiri said. "Secretary Granholm's vision to accelerate deployment of climate solutions matches my own sense of urgency to advance sustainability. I'm honored by the opportunity provide advice where it can be helpful for achieving that goal." [Caltech story]

Dabiri Appointed to President's Council of Advisors on Science and Technology

09-22-21

President Joe Biden has announced the appointment of John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, to the President's Council of Advisors on Science and Technology (PCAST). Presidents have established advisory committees of scientists, engineers, and health professionals ever since Franklin D. Roosevelt created his Science Advisory Board in 1933. "We're here to provide whatever input the president needs," Dabiri says. "My understanding is that we'll be meeting pretty frequently, as the president wants science to be a big part of his decision-making process." [Caltech story]

New Algorithm Helps Autonomous Vehicles Find Themselves, Summer or Winter

06-24-21

Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them—and for the first time, the technology works regardless of seasonal changes to that terrain. The general process, known as visual terrain-relative navigation (VTRN), was first developed in the 1960s. By comparing nearby terrain to high-resolution satellite images, autonomous systems can locate themselves. The problem is that, in order for it to work, the current generation of VTRN requires that the terrain it is looking at closely matches the images in its database. To overcome this challenge, Anthony Fragoso, Lecturer in Aerospace; Staff Scientist, Connor Lee, Graduate student in Aerospace, Austin McCoy, Undergraduate, and Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems and research scientist at JPL, turned to deep learning and artificial intelligence (AI) to remove seasonal content that hinders current VTRN systems.
