Terrasmart's panels already feature PeakYield, a cloud-based tracker control and monitoring software, which allows the panels to move with the sun and avoid clouds to maximize their energy output.

Now, with the TerraTrak feature, the panels will be alerted when a storm is coming and move themselves to a 50- or 60-degree angle to protect themselves from hail or wind damage. The system is fully autonomous, meaning the panels will move without any human prompting, as Electrek detailed.

A new study suggests that this organism likely lived on Earth only 400 million years after its formation.

The paper reads:

“The common ancestry of all extant cellular life is evidenced by the universal genetic code, machinery for protein synthesis, shared chirality of the almost-universal set of 20 amino acids and use of ATP as a common energy currency. As such, our understanding of LUCA impacts our understanding of the early evolution of life on Earth. Was LUCA a simple or complex organism? What kind of environment did it inhabit and when?”

“The evolutionary history of genes is complicated by their exchange between lineages,” University of Bristol’s Edmund Moody, the lead author of the study, said in a press statement. “We have to use complex evolutionary models to reconcile the evolutionary history of genes with the genealogy of species.”

Not satisfied with just learning its age, the team took things a step further and retraced the physiological characteristics of living species to understand what LUCA must’ve been like 4.2 billion years ago—and the results gave some surprising answers. The scientists estimate that while LUCA was a simple prokaryote, it likely had an immune system, meaning it was already fighting off primordial viruses.

SpaceX says it’s been ready to launch the mighty Starship rocket on its fifth test flight since early August, and had been expecting the Federal Aviation Administration (FAA) to give it the green light for the flight to take place in mid-September. But it’s now emerged that the FAA is unlikely to grant a launch license until late November at the earliest.

This delay was not based on a new safety concern, but instead driven by superfluous environmental analysis.”

Starting on September 29, 2024, Earth will briefly have a second "moon" as a small asteroid, 2024 PT5, gets captured by our planet's gravity. This mini-moon will stick around for nearly two months before continuing its journey through space.

commandeered spacewalks. Elon Musk’s SpaceX has new suits and big goals, and it wants to test them as fast as possible. It is now the only private company that delivers humans to live and work in space, and NASA, the space agency of the United States, relies on it.

Polaris Dawn is not a NASA mission, and it is not regulated by the US government. So when its astronauts exit their capsule and ‘walk’ in space, it will mark a massive first for the private industry that is starting to dominate realms beyond Earth.

And this raises a question: Is the US breaking a promise it made 50 years ago about how to operate in space?

Pumping Water - Required Horsepower
Horsepower required to pump water.

Energy imparted to water by the pump is called water horsepower - and can be calculated as

Pwhp = q h SG / (3960 μ)                           

where

Pwhp = water horsepower (hp)

q = flow (gal/min)

h = head (ft)

SG = 1 for water Specific Gravity

μ = pump efficiency (decimal value)

Horsepower can also be calculated as:

Pwhp = q dp / (1715 μ)                   

where

Pwhp = water horsepower (hp)

dp = delivered pressure (psi)
