Scientists found an easier way to produce a chemical reaction important in making biofuels, possibly lowering the cost of biofuel production.

The lack of access to safely managed drinking water now affects some 2.2 billion people worldwide. Addressing this serious problem using existing technologies is a key part of the United Nation’s sustainable development goals – with the organization declaring that everyone should have access to five litres of safe drinking water every day.
This could be achieved in some regions using atmospheric water harvesters (AWHs), which draw clean liquid water out of humid air. There are several different types of AWH, and Lord and colleagues focussed on the solar-driven, continuous-mode AWH (SC-AWH). In such a device, heat from sunlight drives warm, humid air through a heat exchanger where it cools and releases water via condensation. Because a SC-AWH operates during the day when relative humidity tends to be low, it has a low efficiency and it had not been clear which locations worldwide are suited for its use.
With the world’s population estimated to reach 9.8 billion by 2050, scientists are looking at new ways to overcome inevitable food shortages linked to climate change.
Musk recently sold approximately $7 billion in Tesla stock, which skyrocketed in value during the pandemic and made him the world’s richest man.
Reports from various parts of the U.S. indicate that Tesla has started deployment of SpaceX Starlink dishes at Supercharging stations to offer Wi-Fi access (not all sites have W-Fi).
The move was actually announced by Tesla’s COE Elon Musk in October and now at least thea first few sites were equipped with SpaceX Starlink dishes.
Tesla has started to deploy Starlink antennas at Supercharger stations in an apparent effort to offer satellite-based internet to owners while charging.
The Supercharger network currently undeniably offers the best charging experience for electric cars. Other charging networks are closing the gap, but Tesla’s early investment in offering a great complimentary charging experience has paid off.
With charging, the goal is always to make the charging sessions shorter, but it is still not unusual for Tesla owners to spend over 30 minutes at the stations.

The Boring Company’s tunnels are the future of transportation and while some people don’t think so, those who have had the opportunity to try them are sure of it. Skeptical, West Coast Editor of Autoweek, Mark Vaughn, went downstairs to figure out for himself what The Boring Co tunnels are all about—and whether they are as important as Elon Musk says.
Vaughn admits that he was a little skeptical before using the tunnel. He suggested that there would be long lines and too few cars, so it would be faster and easier to simply walk from the West Hall of the Las Vegas Convention Center (LVCC) to the far South Hall. However, after the “critic” descended the escalator into the underground tunnels he was a little surprised to find that the wait was only about a minute. Vaughn said he just walked up to the Tesla Model X, greeted the human driver, and immediately after the door closed, they drove away.
The vehicle is a smart, efficient, and economical way to deliver goods and packages in an urban environment.
NVIDIA plans to build the world’s most powerful AI supercomputer dedicated to predicting climate change, named Earth-2.
The earth is warming. The past seven years are on track to be the seven warmest on record. The emissions of greenhouse gases from human activities are responsible for approximately 1.1°C of average warming since the period 1850–1900.
What we’re experiencing is very different from the global average. We experience extreme weather — historic droughts, unprecedented heatwaves, intense hurricanes, violent storms and catastrophic floods. Climate disasters are the new norm.
We need to confront climate change now. Yet, we won’t feel the impact of our efforts for decades. It’s hard to mobilize action for something so far in the future. But we must know our future today — see it and feel it — so we can act with urgency.
Climate change can cause dramatic shifts in global temperatures and weather patterns. And while scientists won’t be able to reverse all of the negative impacts of these changes, they are looking for ways to lessen the effects by controlling the weather.
