Passive cooling works to beat summer heat, explain scientists

A new research carried out by the University of Oregon measures the impact of passive cooling strategies, especially in regions such as the Pacific Northwest. Passive cooling encompasses pulling down shades during the hottest part of the day and opening windows at night that can keep homes from becoming excessively hot during extreme heat waves.

Simulations of weather data of a severe heat wave in 2021 involving combination of natural and shading ventilation kept temperatures of apartment out of the danger zone during the entire three-day event even without air-conditioning. The load on air conditioning reduced up to 80 percent resultantly.

The findings could be included in building rules to protect renters from the effects of severe heat. This would underpin mandates that apartments have working shades and operable windows that can be safely left open through the night.

In fact, in the Pacific Northwest with cool night air, the climate is amazing for passive cooling. And, this should be taken as an advantage, stated the leader of the study.

Earlier in June 2021, a severe heat wave roasted Washington and Oregon. Temperatures recorded at Portland and Eugene were 116 and 111 degrees Fahrenheit to break previous records.  

The prolonged impact of the heat wave was deadly, and was especially severe on people living in apartments in densely populated urban areas.

The occurrence of such extreme temperatures is only predicted to become more frequent thanks to climate change. Therefore, to figure out a way to make homes liveable during severe summer heat is becoming a problem that needs immediate attention.

Interestingly, design of buildings in the Pacific Northwest is usually for heat to enter. Many homes don’t have air conditioning given the mild summer of the region.

With Easy Human-system Interaction, Wireless Sensors Market for Industrial Street Lighting Applications to Grow

Scientists demonstrate production of food using artificial photosynthesis

Photosynthesis has evolved in plants to convert carbon dioxide, water, and sunlight into biomass and the food we consume. The process, however is highly inefficient with only about 1% energy found in sunlight used in the plant.

In a new development, scientists at the University of Delaware and UC Riverside have discovered a way to bypass the need for natural photosynthesis and create food without use of sunlight by artificial photosynthesis.

The technique published in Nature Food employs a two-step electrocatalytic process to convert CO2, water, and electricity into acetate, which is the form of main component of vinegar. Acetate is ingested by food producing creatures in the dark to grow. The hybrid organic-inorganic system when combined with solar panels to produce the electricity to power the electro catalysis could increase efficiency of conversion of sunlight into food, which could be up to 18 times more for some foods.

The new approach seeks to identify a new way to produce food that could surpass the limits usually imposed by biological photosynthesis, stated corresponding author of the study.

Meanwhile, to join all components of the system, the output of the electrolyzer was optimized to support the growth of food-producing organisms.

Function-wise, electrolyzer is an equipment that uses electricity to change raw materials such as CO2 into useful molecules and products. This resulted in increased amount of acetate produced and decreased amount of salt used with the highest quantity of acetate ever produced in an electrolyzer till date.

With the help of a state-of-the-art two step CO2 electrolysis setup created in the laboratory, the scientists were able to achieve a high selectivity toward acetate that cannot be reached out via traditional CO2 electrolysis routes.
