Strawberries in Water Bottles, Palak in PVC Pipes: 70-YO Grows all Veggies on Terrace

Posted by in categories: business, food, solar power, space, sustainability

For 70-year-old Lizy John from Bengaluru, Karnataka, nurturing a lush vegetable and fruit garden on her terrace has been highly rewarding and satisfying. Without a second thought, she credits her passion for farming to be the sole reason for staying healthy and energetic even at this age.

After running a snacks business for over 25 years, she decided to retire and focus on expanding her farming venture. Though there wasn’t enough space, she says that it wasn’t a challenge at all.

“Though we have a 1,200 sqft terrace, I grow my veggies in less than 1,000 sqft, as the solar panels and water tanks consume the rest of the space. But it was more than enough for me. I admit that I am happier and at peace ever since I started growing my own food at home,” Lizy tells The Better India.

A German institute just broke the solar cell efficiency record with 32.5 percent

Posted by in categories: solar power, sustainability

Solar energy is reaching new heights faster than ever.

A tandem solar cell developed by researchers at the Helmholtz Zentrum Berlin (HZB) has converted 32.5 percent of incident solar radiation into electrical energy, a world record. The achievement was certified by the European Solar Test Installation (ESTI) in Italy, a university press release said.

As the demand for renewable energy grows, researchers are looking at ways of increasing the efficiency of solar cells. This enables more energy to be harvested from the same area of land deployed to generate power. There has been significant success when halide perovskites have been used to make solar cells.

Hot salt, clean energy: How artificial intelligence can enhance advanced nuclear reactors

Posted by in categories: climatology, nuclear energy, robotics/AI, solar power, sustainability

Technology developed at Argonne can help narrow the field of candidates for molten salts, a new study demonstrates.

Scientists are searching for new materials to advance the next generation of nuclear power plants. In a recent study, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory showed how artificial intelligence could help pinpoint the right types of , a key component for advanced nuclear reactors.

The ability to absorb and store heat makes important to and national climate goals. Molten salts can serve as both coolant and fuel in nuclear power reactors that generate electricity without emitting greenhouse gases. They can also store large amounts of energy, which is increasingly needed on an electric grid with fluctuating sources such as wind and solar power.

Producing ‘green’ energy from living plant ‘bio-solar cells’

Posted by in categories: biological, chemistry, food, solar power, sustainability

Though plants can serve as a source of food, oxygen and décor, they’re not often considered to be a good source of electricity. But by collecting electrons naturally transported within plant cells, scientists can generate electricity as part of a “green,” biological solar cell.

Now, researchers reporting in ACS Applied Materials & Interfaces have, for the first time, used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.

In all , from bacteria and fungi to and animals, electrons are shuttled around as part of natural, biochemical processes. But if electrodes are present, the cells can actually generate electricity that can be used externally. Previous researchers have created fuel cells in this way with bacteria, but the microbes had to be constantly fed. Instead, scientists, including Noam Adir’s team, have turned to photosynthesis to generate current.

MIT’s slimmed-down solar cells would add only 20 kg to a rooftop

Posted by in categories: solar power, sustainability, wearables

Solar cell technology is a seen as a key pillar in our transition to cleaner forms of energy, but within this field there is all kinds of room for experimentation. Solar cells that are thin and flexible hold unique promise in the area, as they could be applied to all kinds of irregular, curvy or otherwise unsuitable surfaces. Thinner than a human hair, a new lightweight solar cell from MIT scientists continues to push the envelope in this space.

The MIT team behind the technology sought to build on its previous advances in material science, which in 2016 culminated in ultra-thin solar cells light enough to sit atop a soap bubble without breaking it. As is the case with other thin, light and flexible solar cells we’ve looked at over the years, this pointed to all kinds of possibilities, from paper-based electronics to lightweight wearables that harvest energy throughout your day.

Despite the potential, the team still had some problems to solve, with the fabrication technique for the solar cells requiring vacuum chambers and expensive vapor deposition methods. In order to scale the technology up, the scientists have now turned to ink-based printable materials to streamline the process.

Paper-thin solar cell can turn any surface into a power source (w/video)

Posted by in categories: solar power, sustainability, wearables

MIT engineers have developed ultralight fabric solar cells that can quickly and easily turn any surface into a power source.

These durable, flexible solar cells, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a fixed surface. They can provide energy on the go as a wearable power fabric or be transported and rapidly deployed in remote locations for assistance in emergencies. They are one-hundredth the weight of conventional solar panels, generate 18 times more power-per-kilogram, and are made from semiconducting inks using printing processes that can be scaled in the future to large-area manufacturing.

Outshining conventional solar cells

When they tested the device, the MIT researchers found it could generate 730 watts of power per kilogram when freestanding and about 370 watts-per-kilogram if deployed on the high-strength Dyneema fabric, which is about 18 times more power-per-kilogram than conventional solar cells.

Scientists have provided a solution for humans to achieve immortality and come back from the dead

Posted by in categories: biological, life extension, solar power, sustainability

A Dyson Sphere is a megastructure that has not yet been built. Scientists conceive of it as a giant shell that encloses the sun.

Hypothetically, the Dyson Sphere will be lined with mirrors and solar panels that will collect the energy from the sun. This would be an unimaginable amount of energy.

In theory, the Dyson Sphere would be large enough that it could be a habitable place for humans and it would act as an artificial biosphere in the case that Earth’s supplies have dwindled. It would be a way to ensure survival for the human race.
