India is facing scorching summer heat this year. People often find unique ways to beat the heat. This time, a driver decided to grow a mini garden on his auto-rickshaw’s roof to beat summer. Because of this, he has gotten quite famous as his auto-rickshaw turns a lot of heads on the road. People even stop him to click selfies According to him, the passengers always get happy when they see the plants on the roof. The passengers say that the plants work as a natural air conditioner. He can be seen watering the plants…

Scientists are hopeful that solid-state thermophotovoltaic (TPV) cells with no moving parts can achieve higher efficiencies at higher temperatures when it comes to converting heat into electricity – and lead the way to power grids based entirely on renewables.  One such TPV cell has now hit a new world record of 40 percent efficiency, researchers report. That's better than the steam turbines traditionally used to turn heat into electricity, which typically max out at 35 percent and have upper-temperature limits too.TPVs…

The majority of humanity's electricity comes from heat – burning coal or natural gas, nuclear fission, concentrating solar – that's used to boil water and spin steam turbines. This method of power generation has been around since Charles Parsons first hooked a steam turbine up to a dynamo in 1884, and licensed the patent to George Westinghouse. Over the last century and a half, it's become ubiquitous all over the world as a mature and well-optimized technology with known strengths and limitations. One of those limitations…

Tackling climate change doesn’t just require efforts like renewable energy – we need to clean up existing processes too. Now, engineers have developed a way to use soot from emissions to improve solar thermal devices, making them not only cheaper to produce but more efficient than using materials like graphene.Gathering energy from the Sun doesn’t have to just involve photovoltaic solar cells – collecting its heat can also be used to generate electricity, purify water, cook food, or warm buildings. The best materials for…

With the temperatures rising to a scorching high every day and the heatwave knocking on our door already, one can only imagine how hard things are going to get in the months to come. And while we keep ourselves ready to beat the heat, our cars need a bit of love and attention too. This way, they won’t break down when needed and can spare you from having to get your car fixed in this heat. So, here are some things to keep in mind that will make sure your car is ready not only for the grocery run but also for a road trip if…

The problem is also widespread across the country, affecting not only the typical hot spots in the northwest and southeast but also regions that aren’t used to seeing so much extreme heat, Mondal says. And the effects are even more stark because of a lack of rainfall so far this season. “It’s part of a broader climate-change signal,” says Amir AghaKouchak, a climate researcher at the University of California, Irvine. India’s average annual temperature increased at a rate of 0.62 °C per 100 years between 1901 and 2020,…
