Segway, which boldly claimed its two-wheeled personal transporter would revolutionize the way people get around, is ending production of its namesake vehicle. The Segway PT, popular with tourists and police officers but perhaps better known for its high-profile crashes, will be retired on July 15, the company said in a statement. But the Segway, which carries a standing passenger on a wide platform, accounted for less than 1.5% of the companys revenue last year. The transportation revolution that inventor Dean Kamen envisioned when he founded the company in 1999 never took off. In 2017, Segway got into the scooter business, just as the light, inexpensive and easy-to-ride two-wheelers took over urban streets.

(CNN) - The United States Mint is to memorialize Christa McAuliffe, the teacher and astronaut who died in the Challenger disaster in 1986, with a commemorative silver dollar coin. The Christa McAuliffe Commemorative Coin Act of 2019 was passed by Congress, and the bill will go to the President to be signed into law. The act calls for the Department of Treasury to "issue not more than 350,000 $1 silver coins in commemoration of Christa McAuliffe." If the President signs the act, the coins will be minted in 2021 to commemorate the 35th anniversary of the tragedy.
