Fred Closter doesn’t like Florida Power & Light.
When the Boynton Beach retiree spent $24,000 to install solar panels on the roof of his Boynton Beach home a year ago, he decided not to rely on the utility to power his home when the panels weren’t generating electricity at night and when it rains.
So he dropped another $16,000 on two large lithium ion batteries made by Tesla that can power the home for up to a day and a half if his panels aren’t producing. If a hurricane or other severe storm with the potential to create power outages approaches, the Closters’ solar provider, SunPower, will remotely direct the system to charge their batteries so their power won’t be interrupted.
California-based Azure Printed Homes has announced intentions to construct 14 prefabricated 3D printed homes using recycled plastic. The homes will form part of a new housing development in Ridgecrest, California, led by Oasis Development.
The project will build on Azure’s existing production of backyard studios and ADUs, which it produces from its factory in Culver City, CA. The company claims that 3D printing their ADUs and studios from recycled plastic allows them to build the units 70% faster and with 30% fewer costs than traditional home construction methods.
“At healthy levels, worry can help us anticipate threats and prepare for the future,” says Rebecca C. Cox, the lead author of the research from the Department of Integrative Psychology, University of Colorado, Boulder. “Worry can become a cause for concern if the frequency or intensity of the worry is disproportionate to the source of the worry. If I’m so worried about an upcoming test that I can’t focus on studying, or I’m so frequently worried about storms that I don’t leave my house, then worry has crossed into a problematic range.”
According to previous research, in those with generalized anxiety disorder, worry may function to keep anxiety at a high but predictable level to avoid experiencing an unexpected shift in emotion.
To** **investigate this on a day-to-day level, Cox and her team asked participants to respond to daily survey prompts in the morning, afternoon, and evening to indicate how anxious they felt in that moment. This method, called ecological momentary assessment, is often employed by psychologists to measure emotions in real-time.

Rutgers professor Jason Barr has proposed adding 1,760-acres of reclaimed land, named New Mannahatta, to the tip of Manhattan to provide housing and combat climate change.
Called New Mannahatta in reference to the indigenous name for the island in New York, the plan would extend Manhattan Island into New York Harbor beyond the Statue of Liberty.
Barr, a professor of economics at Rutgers University, outlined his plan in an opinion piece directed at the city’s mayor Eric Adams, which was recently published in the New York Times.
This group appears to be doing its ‘bit’ for NEO identification and is always open to new members, check it out?
IAWN was established (2013) as a result of the UN-endorsed recommendations for an international response to a potential NEO impact threat, to create an international group of organizations involved in detecting, tracking, and characterizing NEOs. The IAWN is tasked with developing a strategy using well-defined communication plans and protocols to assist Governments in the analysis of asteroid impact consequences and in the planning of mitigation responses.
Space colonization requires us to better understand how Earth sustains us.
In the coming decades, space agencies from around the world will be venturing farther out into space than ever before. This includes returning to the Moon (perhaps to stay this time), exploring Mars, and maybe even establishing human settlements on both. Beyond that, there are even proposals for establishing habitats in space that could accommodate millions. These plans build on decades of planning that go back to the dawn of the Space Age. In some cases, the plans are inspired by proposals made over half a century prior to that. While these grand visions for space exploration and colonization present many challenges, they also inspire innovative solutions. In particular, missions to deep-space require fresh thinking about environmental control and life-support systems (ECLSS) that can provide self-sufficiency in terms of air, water, food, and protection from radiation and the dangers of space. These are essential since missions that take astronauts far from Earth cannot depend upon resupply missions from the surface to Low Earth Orbit (LEO).
Full Story:
[Billy] has a special interest in passive hydroponics (also known as the Kratky method), which is a way of growing plants in nutrient-rich water that does not circulate. As the plant grows and liquid level drops, only the tips of the roots remain submerged while more and more of the root surface is exposed to oxygen in a harmonious balance. However, “thirsty” plant types (tomatoes, for example) throw off this balance, and the system needs to be modified. To address this, [Billy] designed and printed a passive float valve system that takes care of topping up the reservoir only when needed, without using pumps or any other electrical equipment.
Commercial or industrial float valves are too big to use in his small tanks, which led [Billy] to test dozens of DIY designs. He used everything from plastic water bottles to pipe ends, but nothing quite measured up. With 3D printing, [Billy] was able to create a sealed, lightweight float that exactly matched the housing and tube locations.
The way [Billy]’s float valve works is by using a hollow object as a kind of buoyant plug inside a housing. When the water level is high, the buoyant object rises up and presses a strip of silicone against an outlet, preventing water from flowing. If the water level is low, the buoyant plug drops and water is free to flow. With a reservoir of fresh nutrient-rich water placed above the grow tank, gravity takes care of pushing a fresh supply down a tube, so no active pump is needed. Combined with a passive float valve, the system pretty much runs itself.
We can summarize this as:
Price = Demand / Supply.
When there is more demand or less supply, the price goes up. When there is less demand or more supply, the price goes down. This is basic economics.
