Researchers have demonstrated a quantum sensor that can power itself using sunlight and an ambient magnetic field, an achievement that could help reduce the energy costs of this energy-hungry technology.
No longer the realm of science fiction, quantum sensors are today used in applications ranging from timekeeping and gravitational-wave detection to nanoscale magnetometry [1]. When making new quantum sensors, most researchers focus on creating devices that are as precise as possible, which typically requires using advanced—energy-hungry—technologies. This high energy consumption can be problematic for sensors designed for use in remote locations on Earth, in space, or in Internet-of-Things sensors that are not connected to mains electricity. To reduce the reliance of quantum sensors on external energy sources, Yunbin Zhu of the University of Science and Technology of China and colleagues now demonstrate a quantum sensor that directly exploits renewable energy sources to get the energy it needs to operate [2].
Thanks to NASA, the world may soon have access to chargers that can top off an EV in as little as five minutes. One of the biggest obstacles to fast charging is dealing with temperature. According to NASA, for an EV to be charged in five minutes, the charger must deliver an electric current of 1,400 amperes. For reference, the fastest chargers currently available max out at around 520 amperes. More amperes equals more heat. A lot more heat. Companies and research organizations are pursuing solutions to the problem; Ford and Purdue University, for example, are exploring liquid-cooled charging cables.
A team sponsored by NASA’s Biological and Physical Sciences Division is working on technology that could provide another solution needed for ultra fast EV charging. The technology has been developed for use in space, in which massive temperature differentials require massive heat transfer capabilities. An experiment to prove the new tech, the Flow Boiling and Condensation Experiment (FBCE), was installed on the International Space Station and is providing data that NASA will use to determine if the system will provide the claimed orders-of-magnitude benefits in heat transfer efficiency.
We’re definitely not NASA-level engineers but we will try to explain the FBCE the best we can. The FBCE is made up of several modules; one of which is called a “Flow Boiling Module” (FBM). When cooling liquid inside the FBM begins to boil, the bubbles formed draw liquid from the inner part of the flow channel to its walls. The process “efficiently transfers heat by taking advantage of both the liquid’s lower temperature and the ensuing change of phase from liquid to vapor.” The technique has been dubbed “subcooled flow boiling.”
The ocean covers most of our planet’s surface, accounts for the majority of our oxygen production, and provides a significant amount of resources by way of food, minerals, and energy.
Yet our oceans are shockingly underrepresented when it comes to environmental conventions on an international scale.
The deep blue yonder is often reduced to footnotes and passing mentions in international accords that aim to unite our world in sustainable practices.
Musk was inspired by Alexander and Napolean, says his father.
Elon Musk is a combination of Albert Einstein, Nikola Tesla, and John D. Rockefeller, according to Dolly Singh, a former SpaceX executive who worked with Musk between 2008 and 2013.

The Elon Musk Show is a three-part documentary, available only in the U.K., that looks to unravel the making of Elon Musk through interviews with family, friends, former employees as well as Musk’s adversaries. The first episode aired last week, while Singh made the comments in the second episode, which Business Insider has previewed.
Taking advantage of the huge output of solar energy in places neighboring the Sahara Desert, a massive undersea power cable is coming to Europe from Egypt. Bringing 3,000 megawatts of renewable energy, the GREGY interconnection will run from northern Egypt to Attica, Greece.
Hi, if you came to this video, you’re probably wondering what would happen if a man lived 1,000 years or more? What possibilities would be open to mankind and how many useful things could be done, if such a thing were possible? Well, then make some tea, make yourself comfortable, and let’s go!
00:00 — Intro. 00:36 — Problems we will face. 2:07 — Is it possible to realize this? 3:19 — How to make it happen? 5:27 — Repair System. 7:26 — Is humanity ready for such a long life? 8:55 — Final.

Of their yearly balance of about €3 million, nearly the entirely is spent on the main congress and other events and conferences. Over the last few years, addressing geography, generation, and gender equities (3G), the International Astronautical Federation established itself as the youngest and most diverse space organization in the world. Over the same period, the IAF President Pascale Ehrenfreund, has pushed her excellent Global Innovation Agenda which “has brought emerging countries to our space family through conferences, expanded work with partner organizations, and created innovative systems for sharing information among members” [1].In his first newsletter [2] the incumbent President, Clay Mowry, communicated the IAF agenda for next 3 years: “Sustainability, Investment and Security”. According to Mowry, “the IAF should seek to influence conversations around the sustainability of the space environment. Securing orbits, spacecraft, frequencies, and physical resources is critical to the future viability of space exploration.” And: “The coming three years will see a shift towards the commercial development of low Earth orbit and major push to field systems in lunar orbits and on the surface of the Moon. We must be prepared to tackle the challenges of growing investment in the space sector head-on. Security refers to the freedom to operate safely in the space domain. Without it, investors and nation states can hardly be expected to pour the continued resources and attention required to secure humanity’s future beyond Earth.”
An agenda oriented to civilian space development? We may say yes, moderately. We want to encourage and further develop this orientation, and we’ll do our best to move IAF more on the side of human expansion into the Geo-Lunar space and the Solar System.
As we said in all of our presentations at IAC 73, “Space for All” is an excellent motto, yet today it is still not yet a reality. We have to work for the realization of that goal, that all Earthers wishing to emigrate into outer space can do it safely, as soon as possible. Such a goal is in perfect continuity with the fully inclusive spirit of IAF! Prominent among the concepts we presented in various symposia and discussions in Paris is that of a modern Eutopia [3] for our time: a fully sustainable inclusive society, one which allows for the healthy and continued growth of 8 billion people. Such an idea cannot be realized within the boundaries of our closed world; but it could be realized through expansion into our celestial frontier.
The San Diego County Water Authority is planning to use its San Vicente Reservoir to store solar power making clean energy in the region viable, according to an article by NPR published on Friday.
Powering 130,000 homes
The project will take ten years to be built and will see large underground pipes connect San Vicente’s lake to a new reservoir about 1,100 feet higher. California’s solar power will pump water into that upper reservoir, storing electricity.
