Electrified Highways Will Recharge Tomorrow's Cars
Scientists at Stanford have pioneered a new way to charge electric vehicles without requiring drivers to stop. The new system would place recharging coils beneath the surface of roads.
What's the Latest Development?
Wireless electricity transfers may power tomorrow's electric cars by making use of recharging coils placed beneath the surface of roads, particularly along interstate highway systems. The coils would be set to the same electromagnetic frequency as the car's battery, allowing an efficient transfer of electricity. Building on work done at MIT in 2006, a Stanford team has "have come up with designs of coil that allow 97% efficient transmission of power over a distance of about 2m (6ft)." The team thinks about 10KW of power can be transferred.
What's the Big Idea?
Wireless highway systems could mean widespread adoption of electric vehicles, according to Dr. Richard Sassoon, a member of the Stanford research team. He says there are three main reasons why people prefer internal combustion engines to electric cars: "One is the short range that an electric vehicle can travel between charges, and that's based on the size of the battery. The second is the lack of a sufficient charging infrastructure, and the third is that even if you can charge, it takes a long time to charge—several hours. That means you’re going to have to take a break in your trip in order to charge your vehicle."

The issues that determine your health go way beyond seeing your doctor.
- The average American spends about 24 hours a year at the doctor's office.
- What you do the other 364 days a year mostly determines your health.
- Michael Dowling discusses Northwell's focus on environmental, social, economic and other social determinants of health.
The blood of horseshoe crabs is harvested on a massive scale in order to retrieve a cell critical to medical research. However, recent innovations might make this practice obsolete.
- Horseshoe crabs' blue blood is so valuable that a quart of it can be sold for $15,000.
- This is because it contains a molecule that is crucial to the medical research community.
- Today, however, new innovations have resulted in a synthetic substitute that may end the practice of farming horseshoe crabs for their blood.
