A breakthrough method uses solar energy to produce green hydrogen from water

Posted by in categories: solar power, sustainability

Scientists have proposed a solar energy-driven photocatalytic method to split water. This method uses iridium as a metal catalyst and is believed to be capable of producing green and clean hydrogen fuel on a large scale.

Physicists Say There May Be Another Reality Right Beyond This One

Posted by in categories: materials, physics

For those of us worried the world somehow got trapped in the wrong timeline, relax — scientists are now saying there might actually be two realities.

Two researchers from the University of Maryland released their findings in a study earlier this month in the journal Physical Review Research. According to a university press release, though, a second reality isn’t exactly what they set out to find. While studying layers of graphene, made with hexagons of carbon, the found repeating patterns that changed the way electricity moves.

Based on their research, the pair think they accidentally found a clue that could explain some of our current reality’s mysteries. According to the university’s media arm, they realized that experiments on the electrical properties of stacked sheets of graphene produced results that looked like little universes and that the underlying causes could apply to other areas of physics. In stacks of graphene, electricity changes behavior when two sheets interact, so the two hypothesize that unique physics could similarly emerge from interacting layers elsewhere—perhaps across the entire universe.

Is Solar Energy from Outer Space in Our Future? — Part One: Building a Geosynchronous Solar Power Plant

Posted by in categories: satellites, solar power, sustainability

Today a state-of-the-art solar panel on Earth can convert between 20 to 30% of the energy it collects from sunlight into electricity. At night solar panels here contribute nothing. But in space with nothing to block the Sun, that same Earth-based solar panel becomes thirteen times more efficient. And that is enough of an incentive to consider solar power from space.

The Chinese and UK models are massive arrays located in geosynchronous orbit while continuously beaming energy to receiving stations here on Earth.

The US model is different using a constellation of solar power generating satellites. These would be in relatively low orbits and interconnected to form a mesh network. The total network would generate continuous energy beaming it to the surface even when a portion of it gets blocked when the satellites enter the night side of the planet.

Hackers Are Starting To Target EV Charging Stations

Posted by in category: cybercrime/malcode

As the world rapidly shifts to EV transport, the automotive industry is experiencing some major teething issues. The global charging network is having to keep pace with more and more EVs on the road, and as manufacturers expand their networks, cracks are starting to appear in their grand schemes. We recently reported that a long string of EV chargers outside of Moscow were hacked by Ukrainian programmers to display anti-war and anti-Putin messaging, and there have even been cases in the UK where charging station displays showed graphic images. Hacking EV infrastructure is becoming more commonplace, and it could be a bigger issue than many might think.

We believe Mars may once have had oceans and sky, but lost them from a lack of a magnetosphere. How does this happen, and how can we create a magnetosphere for Mars so we can terraform and live on it?

MIT researchers have developed a system that enables a robot to learn a new pick-and-place task based on only a handful of human examples. This could allow a human to reprogram a robot to grasp never-before-seen objects, presented in random poses, in about 15 minutes.
