But it comes with an extra-long keel. Sailing through the seas is full of adventures, but you miss 29 percent of the world when you’re on a yacht.

The Air Yacht uses solar energy as an extra power source thanks to two solar-powered blimps instead of traditional parallel hulls.

Can we deploy a constellation of solar power generating satellites to energize the entire planet? It is feasible.

In this second part of a two-part series, we look at a constellation of solar satellites as an alternative to geosynchronous power arrays.

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.

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.

Less than a millionth of a billionth of a second long, attosecond X-ray pulses allow researchers to peer deep inside molecules and follow electrons as they zip around and ultimately initiate chemical reactions.

Scientists at the Department of Energy’s SLAC National Accelerator Laboratory devised a method to generate X-ray laser bursts lasting hundreds of attoseconds (or billionths of a billionth of a second) in 2018. This technique, known as X-ray laser-enhanced attosecond pulse generation (XLEAP), enables researchers to investigate how electrons racing about molecules initiate key processes in biology, chemistry, materials science, and other fields.

“Electron motion is an important process by which nature can move energy around,” says SLAC scientist James Cryan. “A charge is created in one part of a molecule and it transfers to another part of the molecule, potentially kicking off a chemical reaction. It’s an important piece of the puzzle when you start to think about photovoltaic devices for artificial photosynthesis, or charge transfer inside a molecule.”

“In light of significant efforts being taken toward manned deep space exploration, it is of high technological importance and scientific interest to develop the lunar life support system for long-term exploration. Lunar in situ resource utilization offers a great opportunity to provide the material basis of life support for lunar habitation and traveling. Based on the analysis of the structure and composition, Chang’E-5 lunar soil sample has the potential for lunar solar energy conversion, i.e., extraterrestrial photosynthetic catalysts. By evaluating the performance of the Chang’E-5 lunar sample as photovoltaic-driven electrocatalyst, photocatalyst, and photothermal catalyst, full water splitting and CO₂ conversion are able to be achieved by solar energy, water, and lunar soil, with a range of target product for lunar life, including O₂, H2, CH4, and CH3OH. Thus, we propose a potentially available extraterrestrial photosynthesis pathway on the moon, which will help us to achieve a “zero-energy consumption” extraterrestrial life support system.”

Chang’E-5 lunar soil was used as the lunar extraterrestrial photosynthetic catalyst for water splitting and CO₂ conversion. Solar energy and water were converted into a wide range of valuable products for lunar life support, including O₂, H2, CH4, and CH3OH. A “zero-energy consumption” extraterrestrial life support system was thus proposed.
