Hurricane Resistant Homes

Posted by in categories: climatology, engineering, habitats, sustainability

Deltec Homes is changing the way the world builds. For over five decades, we have designed and engineered homes to fight climate change and withstand the harshest of weather conditions. The connections, both inside and out, that our homes provide make it truly the strongest home for people and our planet.

The engineering and innovation behind each Deltec is why they have stood against some of the most detrimental storms in history including direct hits from Hurricanes Dorian, Michael, Maria, Irma, Harvey, Sandy, Katrina, Hugo, Ivan and Charley.

Rooftop wind system delivers 150% the energy of solar per dollar

Posted by in categories: energy, space, sustainability

Aeromine says its unique “motionless” rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.

Distributed energy generation stands to play a growing part in the world’s energy markets. Most of this currently comes in the form of rooftop solar, but in certain areas, wind could definitely play a bigger part. Not every spot is appropriate for a bladed wind turbine, though, and in this regard, University of Houston spinoff Aeromine Technologies has designed a very different, very tidy form of rooftop wind energy capture that looks like it could be a real game-changer.

A “Green” Quantum Sensor

Posted by in categories: energy, internet, nanotechnology, quantum physics, space, sustainability

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].

NASA Space Tech Could Give Us 5-Minute Electric Car Charging Times

Posted by in categories: biological, space, sustainability

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.”

Scientists Call For The Ocean to Be Recognized as a Living Being With Inherent Rights

Posted by in categories: energy, food, sustainability


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.
