10 Infrastructure Projects We’d Like to See Get Off the Ground

Posted on by robbie

In his victory speech, Donald J. Trump vowed to “rebuild our highways, bridges, tunnels, airports, schools, hospitals.” The investment is long overdue: The American Society of Civil Engineers, in its most recent national assessment, rated the country’s infrastructure as a D-plus, just above failing. The group estimates that, by 2025, the nation will need a $1.44 trillion boost over current funding levels to meet growing needs.

Since 2009, when Barack Obama doled out roughly $800 billion in a stimulus package, that money’s been hard to come by, largely blocked by partisanship. But advocates hope the election of Trump, who made his fortune in real estate, could launch a building boom. The Republican president, so used to seeing his name on gilded skyscrapers, hotels, casinos and golf courses, could cut a deal with congressional Democrats, who view public-works projects as an engine for job growth.

Assuming Trump can indeed pass a bill, we at NationSwell have a few ideas for him to consider. A big, beautiful wall’s not one of them; instead, here’s the top 10 shovel-worthy alternatives we’d like the new administration to undertake.

The Cars of the Future Might Be Powered By… Algae

Oil is going green — literally. Scientists at the Pacific Northwest National Laboratory (PNNL) have discovered a way to simplify the process of turning algae and water into crude oil. The process, called hydrothermal liquefaction, has long been touted as a viable way to produce more energy. In fact, most of the oil that’s drilled from the ground was formed by algae, compacted and heated over the course of millions of years until it transformed into petroleum. But now scientists have figured out how to quickly reproduce the process in the lab, converting algae into oil in less than an hour.
“It’s a way of mimicking what happens naturally over an unfathomable length of time,” says lead investigator Douglas C. Elliott. “We’re just doing it much, much faster.”
So how does it work? PNNL researchers mix 20% algae with 80% water, and send the mixture down a tube at 660 degrees Fahrenheit and 3,000 psi for 30 minutes. The pressure cooker breaks down the algae and converts it into oil. An added bonus is that the process yields byproducts, such as carbon dioxide, hydrogen and oxygen, which can be reused to generate more heat or fertilize the algae.
The same hydrothermal liquefaction process can also be used on other organic wastes, such as manure, sewage or compost, which could have big implications for recycling waste into energy all across the country. Researchers’ next challenge is figuring out how to make the process cheap. Algae-powered cars aren’t here yet, but they’re a bit closer thanks to this new innovation.
