By Matt O’BrienThe US is in the middle of an experiment to build lightning rods that can detect lightning and predict its direction and direction with a 99.9 percent accuracy, but the rods themselves could be the subject of a lawsuit.

On Thursday, the US National Science Foundation announced a $500,000 grant to build the prototype in San Francisco.

That’s the largest grant for a new research project to date.

The funding will be used to test and optimize the technology, which is expected to cost about $1 million. 

The rods are to be used by the US Army, NASA, the National Oceanic and Atmospheric Administration, the Federal Emergency Management Agency and other federal agencies, the NSF said.

The rods will also be used in the US Department of Energy’s National Institute of Standards and Technology, which runs the National Lightning Reception and Detection System (NLRS).

The project will be led by a group led by David B. Hartman, a professor of electrical and computer engineering at Carnegie Mellon University.

Hartmann said that the team is developing the prototype by working on the research paper that was published in Science. 

“The research project is a unique effort to advance our understanding of lightning and its lightning rod,” Hartman said in a statement.

“We hope to build on our knowledge to provide the best lightning rod ever made.”

The researchers plan to use the rods to study the lightning that occurs in the United States every week, Hartman added.

He said the rods are also used by scientists in countries around the world to study how lightning behaves.

Hartmer said that scientists are developing a number of models to understand lightning and how it propagates in the atmosphere.
