Anti-solar panel can generate electricity at night, researchers say

Posted by in categories: solar power, sustainability

In order to develop solar panels that generate electricity at night, you just need them to operate in the exact opposite way solar panels work during the day.

Tesla releases first Model Y production picture, hints at body manufacturing breakthrough

Posted by in categories: finance, sustainability, transportation

Tesla has released the first official picture of a Model Y production vehicle, as well as pictures of the production line pictures — hinting at their previously discussed body manufacturing breakthrough.

With the release of Tesla’s Q4 2019 financial results, the automaker also announced the start of Model Y production, which happened earlier this month, and the start of deliveries in March.

For almost a year now, we have seen Model Y pre-production prototypes on public roads as part of Tesla’s extensive test program.

Elon Musk: Tesla faces battery woes, but future will ‘blow people’s minds’

Posted by in categories: Elon Musk, robotics/AI, sustainability, transportation

So what’s Tesla to do? The answers may come in the Battery Day, a forthcoming explainer that could take place in April. The day is expected to be similar in setup to the Autonomy Day in April 2019, where Musk explained to investors the company’s progress on full self-driving capabilities.

What will they show? One of the standout features may be the company’s Maxwell Technologies acquisition. The $218 million deal, announced February 2019, brings in a firm working on exotic technologies like dry electrodes and ultracapacitors. The firm has also identified a pathway to raising battery density to 500 watt-hours per kilogram. Current batteries tend to weigh around 300 watt-hours, but a jump to 500 could enable advanced uses like an electric plane.

Musk confirmed during Wednesday’s call that Tesla is working with Maxwell, while also stating that its ultracapacitor technology is an “important piece of the puzzle.” This exotic technology could transform how energy is managed within the car, and Musk was actually planning to do his PhD at Stanford University on them before he dropped out.

These solar-powered barges can scoop up 50 tons of plastic from rivers each day

Posted by in categories: robotics/AI, sustainability

While removing the plastic waste that currently contaminates the ocean today will be crucial for protecting marine ecosystems, it is arguably more important that we stop any more plastic trash from entering the ocean. Fortunately for humanity, The Ocean Cleanup, a nonprofit taking on plastic waste in the ocean today, also has a novel solution for stopping plastic from entering it via rivers.

The solution comes in the form of a solar-powered barge named the “Interceptor”. The 24-meter-long (78 feet) vessel resembles a large houseboat and uses a curved barrier to catch waste floating downstream. The trash, much of it plastic, is directed to the “mouth” of the barge — which operates autonomously and silently — from where it rolls up a conveyor belt and is dropped into dumpsters. Apparently, the Interceptor is capable of collecting up to 50 tons of waste a day.

Currently the Klang River in Malaysia is home to one of these Interceptors where it can be seen quietly scooping up trash. The Klang river alone sends more than 15,000 tons annually into the sea, making it one of the 50 most-polluting rivers across the globe. As well as the barge in Malaysia, one has been stationed in Jakarta, the overcrowded capital of neighboring Indonesia, while two others will be sent to Vietnam and the Dominican Republic.

New Tech Will Disinfect Everything and Help Stop Infectious Diseases

Posted by in categories: biotech/medical, food, health, nanotechnology, sustainability

Nanosafety researchers at the Harvard T.H. Chan School of Public Health have developed a new intervention to fight infectious disease by more effectively disinfecting the air around us, our food, our hands, and whatever else harbors the microbes that make us sick.

They used a nano-enabled platform developed at the center to create and deliver tiny, aerosolized water nonodroplets containing non-toxic, nature-inspired disinfectants wherever desired.

This skyscraper-sized air purifier is the world’s tallest

Posted by in categories: biotech/medical, engineering, sustainability

Circa 2018

It may look like just another giant smokestack, but a 200-foot tower in the central Chinese city of Xi’an was built to pull deadly pollutants from the air rather than add more. And preliminary research shows the tower — which some are calling the world’s largest air purifier — has cut air pollution significantly across a broad swath of the surrounding area.

Given those findings, the researchers behind the project say they hope to build an even taller air-purifying tower in Xi’an, and possibly in other cities around China.

Moss-growing concrete absorbs CO2, insulates and is also a vertical garden

Posted by in categories: biological, climatology, sustainability

Buildings with this concrete can—in regions with a calm mediterranean climate—absorb CO2 and release oxygen with micro-algae and the other “pigmented microorganisms” that coat it. These vertical gardens boast aesthetic appeal, but the biological concrete’s beauty also lies in its clever design.

3_Moss growing concrete CO2

The concrete works in layers. The top layer absorbs and stores rainwater and grows the microorganisms underneath. A final layer of the concrete repels water to keep the internal structure safe. The top can also absorb solar radiation, which insulates the building and regulates temperatures for the people inside.
