Group of Engineers Proposed a Wall on the U.S./Mexico Border That’ll Pay for Itself

The US/Mexico border has been the subject of some pretty hotly contested debates recently. However, that debate could potentially be settled by a group of 28 engineers from a dozen universities, who came together to propose a wall that they believe would make those who desire a wall happy while also emphasizing alternative energy.

The plan calls for a 2,000-mile industrial park along the border that would contain natural gas pipelines, solar energy panels, wind turbines, and desalination facilities.

The group believes this could be a win-win situation: “Given that most of the southern border lies in arid or semi-arid regions having high solar irradiation and wind, an energy park along the border is both feasible and desirable.”

The engineers estimate that a solar energy park along the whole border would produce the same amount of energy as a nuclear power plant. The wall would also create scores of jobs and help to assist a positive relationship between the U.S. and Mexico based on mutual interests.

Luciano Castillo of Purdue University, the group leader, said, “Democrats want a Green New Deal. Republicans want border security. Both parties could win. It could be a win–win for the U.S. and Mexico, too. This idea could spark a completely new conversation about the border. And we need that.”

What do you think? Let us know in the comments.

People are Building Bridges for Animals to Safely Cross Freeways

It’s always a terrible sight to see a dead animal on the highway, whether it’s a deer, coyote, dog, cat, armadillo, or whatever. Unfortunately, we’ve built endless ribbons of roads through wilderness (aka, the homes of animals) and that is just part of everyday life. It’s estimated that roads affect one-fifth of the ecology of the entire United States and that vehicle collisions with animals cost $8 BILLION per year.

Of course, you’ve seen the “Deer Xing” signs and other notices for animals that might be in a particular area, but those warnings can only do so much. That is why animal overpasses and underpasses are so important to maintaining animal habitats and saving the lives of all kinds of creatures – not to mention the hoods of our cars.

The trend started in France in the 1950s, and Europe remains a trendsetter for animal bridges. The Netherlands alone has 66 bridges scattered throughout the country to protect their wildlife, like the one you can see above. Below is an example of an animal bridge in Belgium:

The trend has taken hold in the United States and Canada over the past 30 years. The bridges and underpasses come in all shapes and sizes and are specifically designed for each ecosystem. Here is an example from New Jersey.

Here are some other great examples from across the globe. One from Germany.

Here’s a video about the animal crossings in Banff National Park in Canada that will give you some more insight into how important this trend really is.

Now this is a trend we can all get behind in a big way.

Portland, Oregon is About to Generate Electricity from the City’s Water Pipes

The need for modern societies to move beyond fossil fuels and develop renewable energy alternatives is undeniable. Towards those efforts, city planners of the world should keep an eye on what’s happening in Portland, Oregon.

The city has partnered with a company called Lucid Energy to generate clean electricity for the city by utilizing the water already flowing beneath the city.

A section of Portland’s water system was replaced by pipes designed by Lucid Energy that contain four 42″ turbines. As the water flows through the pipes under the city’s streets, the turbines spin and provide energy that is put into the city’s electrical grid.

Lucid Energy says this will be “first project in the U.S. to secure a 20-year Power Purchase Agreement (PPA) for renewable energy produced by in-pipe hydropower in a municipal water pipeline.” One big advantage that this type of energy-generating system has is that it isn’t affected by the weather, like solar and wind power are.

The water must be moved by gravity because the energy required to pump water through pipes would make the energy generated by this technology pointless. In other words, cities with an abundance of hills will be the winners with this technology.

When the project is complete it is supposed to generate power to up to 150 homes. While that might not sound like a lot, it is a great start for what is basically a brand new technology.

Take a look at this video to learn more about the project.

Hopefully, city planners and civic leaders around the country are paying attention to what’s going on in Portland.

In 1969 Forrest Parry, an IBM engineer, had the idea to affix magnetic tape to a plastic card. Every adhesive failed. He went home frustrated. His wife was ironing when he walked in. She suggested he fuse the tape onto the card with the iron. It was a success, and the magstripe card was born. […]
