SAN FRANCISCO (KRON) – On today’s edition of Rob Black’s Winners and Losers, our financial expert Rob Black and KRON 4’s Mark Danon about gas prices, why Apple is hiring nurses and hyperloop wars.

Gasoline prices dropped below $2 across most of the nation early in the year when crude dropped to $30 a barrel. In some isolated cities, the price fell to very close to $1. The pendulum has swung the other way, as oil has moved above $45. Gas prices have risen very close to $3 for a gallon of regular in several of California’s largest cities. The average price for a gallon of regular across the country is $2.21. That is up from $2.04 a month ago.

Apple has a lab dedicated to sports and health in which Apple employees work out under close supervision using medical monitoring equipment. The lab even has chambers that can simulate temperature or weather conditions, to better fine-tune the Watch’s sensors. The lab is staffed by professional nurses, which explains why Apple has been hiring them lately.

A crowdsourced enterprise led by NASA and Boeing veterans called Hyperloop Transportation Technologies announced it had licensed passive magnetic levitation technology to power its prototype system, which like other hyperloop templates, promises to shuttle humans and goods in a vacuum tube system at speeds up to 750 mph. How fast is that? Zipping from Los Angeles to San Francisco would take 30 minutes as compared to a six-hour drive or an all-day train ride.
