Singapore has only 1% of its land available for agriculture, so it imports 90% of its food requirements. The government is looking to curb this dependence on outside food sources under a programme titled ‘30 by 30,’ which aims to allow Singapore to grow 30% of its produce by the year 2030. Local vertical farms like Sustenir are at the forefront of bringing about this change. VICE visits the sustainable start-up to understand the future of food.

Imperial College London has partnered with British startup Arborea to install the world’s first “Biosolar Leaf” technology on its roof. It is first of the kind system to use the microscopic plant to purify the air while producing plant-based food.

Julian Melchiorri CEO of Arborea who pioneered “Biosolar Leaf” technology said – “There has to be a way to feed all the world with healthy and sustainable food by making it the primary choice, not the alternative!”

The system works by growing microscopic plants like blue-green algae, phytoplankton on a solar grid-like layout. In fact, just one acre of “Biosolar Leaf” can remove carbon dioxide and produce breathable oxygen, then, one hundred acres of trees.

While it probably won’t make it to your dining table, a new scientific achievement might be able to help in everything from radar equipment to electric cars: scientists have been able to form salt, aka sodium chloride (NaCl), in a hexagonal shape.

This is work done at the smallest of scales, with researchers able to get a thin film of hexagonal salt to form on top of a layer of diamond, due to the chemical interaction of both film and diamond substrate – something the team actually predicted would happen in advance through simulations.

It’s the latest in a series of discoveries where scientists have been able to synthesise 2D materials with unusual crystal structures, and it’s partly this self-imposed restriction to two dimensions that is enabling new and exotic structures to be formed.

Highly energetic, “hot” electrons have the potential to help solar panels more efficiently harvest light energy.

But scientists haven’t been able to measure the energies of those electrons, limiting their use. Researchers at Purdue University and the University of Michigan built a way to analyze those energies.

“There have been many theoretical models of hot electrons but no direct experiments or measurements of what they look like,” said Vladimir “Vlad” Shalaev (shal-AYV), Purdue University’s Bob and Anne Burnett Distinguished Professor of Electrical and Computer Engineering, who led the Purdue team in this collaborative work.

Although tidal energy is still in its infancy, it could help to reduce Australia’s dependence on fossil fuels.

“The majority of the energy in the national grid is from coal,” explained Jenny Hayward, a research scientist at Australia’s national science agency, CSIRO. “We also have wind and solar PV [photovoltaic].”

Solar power systems with double-sided (bifacial) solar panels—which collect sunlight from two sides instead of one—and single-axis tracking technology that tilts the panels so they can follow the sun are the most cost effective to date, researchers report June 3rd in the journal Joule. They determined that this combination of technologies produces almost 35% more energy, on average, than immobile single-panel photovoltaic systems, while reducing the cost of electricity by an average of 16%.

“The results are stable, even when accounting for changes in the weather conditions and in the costs from the solar panels and the other components of the photovoltaic system, over a fairly wide range,” says first author Carlos Rodríguez-Gallegos, a research fellow at the Solar Energy Research Institute of Singapore, sponsored by the National University of Singapore. “This means that investing in bifacial and tracking systems should be a safe bet for the foreseeable future.”

Research efforts tend to focus on further boosting energy output from solar power systems by improving solar cell efficiency, but the energy yield per panel can also be increased in other ways. Double-sided solar panels, for example, produce more energy per unit area than their standard counterparts and can function in similar locations, including rooftops. This style of solar panel, as well as tracking technology that allows each panel to capture more light by tilting in line with the sun throughout the day, could significantly improve the energy yield of solar cells even without further advancements in the capabilities of the cells themselves. However, the combined contributions of these recent technologies have not been fully explored.

Although perovskites are a promising alternative to the silicon used to make most of today’s solar cells, new manufacturing processes are needed to make them practical for commercial production. To help fill this gap, researchers have developed a new precision spray-coating method that enables more complex perovskite solar cell designs and could be scaled up for mass production.

Perovskites are promising for next-generation solar cells because they absorb light and convert it to energy with better efficiency and potentially lower production costs than silicon. Perovskites can even be sprayed onto glass to create energy-producing windows.

“Our work demonstrates a process to deposit perovskite layer by layer with controllable thicknesses and rates of deposition for each layer,” said research team leader Pongsakorn Kanjanaboos from the School of Materials Science and Innovation, Faculty of Science, Mahidol University in Thailand. “This new method enables stacked designs for solar cells with better performance and stability.”

A Tesla owner has demonstrated a rather novel way to charge his Model 3. In a recent video, Sean Callaghan of the ItsYeBoi YouTube channel opted to use a series of off-the-shelf solar panel sheets onto a towable trailer to create a mobile charging unit for his all-electric sedan.

Callaghan planned to use only the sun and the solar sheets purchased from e-commerce platform Wish to charge his Model 3. The solar panel sheets would collect energy from the sun and transfer it to a control panel. The control panels were connected to batteries that would hold the energy—the batteries connected to an inverter, which would then charge the Tesla Model 3.

The entire assembly would provide the Model 3 with about 800 watts of energy on a completely sunny day. However, Callaghan shot the video when weather was overcast, so the entire solar panel trailer build only managed to provide around 300 watts throughout the YouTube host’s test.
