Gainesville Solar Walk Gainesville, Florida - A trek through the solar system here on earth.

THE GAINESVILLE SOLAR WALK IS a four-billion-to-one scale model of the solar system. The entire display spans one mile. Each pillar has info and artifacts about the celestial body it features.

The installation was created in 2002 as a joint project of the City of Gainesville, the Alachua Astronomy Club, artist Elizabeth Indianos, as well as graphic artist Saydi Kaufman. The project cost around $30,000.

Each pillar represents a different planet, Pluto is also included. The planet pillars also feature quotes, stones, and other repurposed objects. Two comets are also present along the walk.

Enhancements are still being discussed, including additional seating, nighttime lighting, an asteroid rock ...

Swiss on track to be the first airline to use solar fuel

Swiss are to become the first airline in the world to power planes by “liquid sunlight.”

The airline, which is owned by Lufthansa Group, has struck a deal with Synhelion, a company that uses solar energy to convert CO2 into a synthetic fuel called syngas.

Swiss-based Synhelion, which is a spinoff from the Swiss Institute of Technology, has mastered a way of manufacturing sustainable aviation fuel (SAF) from renewable energy sources.

And the move, the airline says, is the first step towards making the aviation industry more sustainable through carbon-neutral, fossil-free flying.

But what is syngas?

Syngas is a liquid fuel with the same properties as fossil fuels, but it is produced art...

Stunning aerial photographs show the impressive solar infrastructures that will soon power the whole world

Aerial view of Ivanpah Solar Power Facility in California.The Ivanpah Solar Power Facility, near Ivanpah Dry Lake, California, generates enough electricity to serve more than 140,000 homes in the state during the peak hours of the day while reducing 400,000 tons of carbon dioxide emissions per year.

What will the world of the future look like?

It's a question that's increasingly inescapable in the era of global warming, or, as scientists increasingly call it, the Anthropocene: a world shaped by humans, the machines we use, and the pollution those emit—a world of anthropogenic change.

The war in Ukraine is exposing in harsh terms the world's continued heavy reliance on old-school fossil fuels, as gas prices skyrocket with the U.S. banning the ...

Energy Solutions: What to Know about Solar Panel ROI


In recent years, solar panels have become more accessible. Many homes today use them simply because they cut down on energy bills. Aside from that, they're also eco-friendly. Because of this, many solar panel owners use theirs as leverage to gain a return on investment (ROI).

The ROI for solar panels is calculated by taking the value of electricity generated by your solar panels and subtracting your energy expenses. The result is the value you'll receive when you sell your home. According to the Department of Energy, solar panels can add up to $20,000 to the value of a home, which is a hefty amount of money. However, it doesn't stop there because other things factor in solar panel ROI.
