Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]

How do we cut U.S. global warming gas emissions by 50 percent within the next 10 years? For starters, be a part of the solution: jump on Zoom for the Caltech Energy 10 (CE10) public program on June 14–15 to join researchers as well as industry and government leaders as they outline the steps needed to meet this ambitious goal. "We are seeing the effects of climate change ramp up faster than expected, and there is widening consensus that the time for action is now," says Harry A. Atwater, Otis Booth Leadership Chair of the Division of Engineering and Applied Science, Howard Hughes Professor of Applied Physics and Materials Science, and director of the Liquid Sunlight Alliance. "Rewiring U.S. energy production and consumption is one way to tackle this worsening issue head-on and in a practical way." [Caltech story]

The student winners of the 2022 Demetriades - Tsafka - Kokkalis Prizes were announced at the end of this academic year. Ida Qin, advised by Professor Joel Burdick has received the prize in Biotechnology. Her research is in comprehensive temporal understanding and state estimation during robot-assisted surgery. Alan Gu, advised by Professor Michael R. Hoffmann has received the prize in Entrepreneurship. His research is in capturing CO2 at point emission sources to accelerate reaching a goal of carbon neutrality. Joeson Wong, advised by Professor Harry A. Atwater has received the prize in Nanotechnology. His research is focused on the optoelectronic physics and engineering of atomically thin photovoltaics. Fengyu Zhou, advised by Professor Steven Low has received the prize in Environmentally Benign Renewable Energy Sources. His research involves the global optimality and relaxation exactness of the Optimal Power Flow problem in single-phase and multi-phase networks. Stacy Larochelle, advised by Professor Jean-Philippe Avouac and Professor Nadia Lapusta has received the prize in Seismo-Engineering, Prediction, and Protection. Her research uses geodesy, data analysis and modeling to further the understanding of mechanical interactions between water and the solid Earth, from fluid-induced earthquakes to groundwater extraction.

Caltech-based startup company Captura, which captures carbon dioxide (CO2) from ocean water to combat climate change, has been awarded $1 million from the XPRIZE Carbon Removal competition. Captura was co-founded by Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance, and Chengxiang "CX" Xiang, Research Professor of Applied Physics and Materials Science. It has the potential to scale up to harvesting gigatons of carbon dioxide—that is, billions of tons—from the ocean every year. "As far as we can tell, Captura is one the very few companies that is doing carbon capture from ocean water," Xiang says. [Caltech story]

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]

The American Institute of Mathematics (AIM), an independent nonprofit organization funded in part by the National Science Foundation (NSF), is moving to Caltech's campus from its current home in the Bay Area. AIM organizes and funds focused collaborations among pure and applied mathematicians, theoretical biologists, computer scientists, physicists, and other scientists working on long-standing math problems. "The arrival of AIM at Caltech will build new bridges between math, applied math, and computational science, and will shine a spotlight on the role that mathematical thinking plays across all our departments and options," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance.

A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which the light strikes the material. "Negative refraction is crucial to the future of nanophotonics, which seeks to understand and manipulate the behavior of light when it interacts with materials or solid structures at the smallest possible scales," says Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute. [Caltech story]
