Startup enables 100-year bridges with corrosion-resistant steel

  • Allium Engineering, founded by two MIT alumni, has developed a process for improving steel rebar to triple the lifetime of bridges and other infrastructure.

Now Allium Engineering, founded by two MIT PhDs, is tripling the lifetime of bridges and other structures with a new technology that uses a stainless steel cladding to make rebar resilient to corrosion. By eliminating corrosion, infrastructure lasts much longer, fewer repairs are required, and carbon emissions are reduced. The company’s technology is easily integrated into existing steelmaking processes to make America’s infrastructure more resilient, affordable, and sustainable over the next century.

Allium is also experimenting with other cladding materials and composites. Down the line, Jepeal sees Allium’s tech being used for things beyond rebar like train tracks, steel beams, and pipes. But he stresses the company’s focus on rebar will keep it busy for the foreseeable future.

“Almost all of our infrastructure has this corrosion problem, so it’s the biggest problem we could imagine solving with our set of skills,” Jepeal says. “Tunnels, bridges, roads, industrial buildings, power plants, chemical factories — all of them have this problem.”

Considering that the Gooferment is up to “its elbows” in bridge construction, it’s no wonder that the bridges are falling down.  If an entrepreneur was “selling bridges”, then we would have bridges that would last virtually forever.  But politicians and bureaucrats have no incentive to solve the problems of the world. 

Argh!

INNOVATION: Another significat contribution to the public domain

Low-cost device can measure air pollution anywhere

  • Open-source tool from MIT’s Senseable City Lab lets people check air quality, cheaply.

Air pollution is a major public health problem: The World Health Organization has estimated that it leads to over 4 million premature deaths worldwide annually. Still, it is not always extensively measured. But now an MIT research team is rolling out an open-source version of a low-cost, mobile pollution detector that could enable people to track air quality more widely.

The detector, called Flatburn, can be made by 3D printing or by ordering inexpensive parts. The researchers have now tested and calibrated it in relation to existing state-of-the-art machines, and are publicly releasing all the information about it — how to build it, use it, and interpret the data.

“We” should have an award for people who make a discovery and make it free to use because of its great benefit.

It should be named for Frederick Banting (note below) for insulin or Volvo for the three point seat belt.

Maybe Volvo would sponsor it.

I’d nominate these folks from MIT for this invention and releasing it to the public domain.

Note: When inventor Frederick Banting discovered insulin in 1923, he refused to put his name on the patent. He felt it was unethical for a doctor to profit from a discovery that would save lives. Banting’s co-inventors, James Collip and Charles Best, sold the insulin patent to the University of Toronto for a mere $1.
