Severinsky's bright idea was to run the electric motor on a high voltage--say, 40 times the 14 volts that is standard for the electrical system in a gasoline car with a 12-volt battery.
There are projects updating the seismic strength of structures (although most of those projects have already been completed), updating the electrical system to give more flexibility, adding special track to give the trains greater maneuverability between tracks, etc.
Aviation officials in the U.S. and Japan are trying to determine if the two major incidents this month were caused by malfunctions in the lithium-ion batteries or if some other part of the electrical system was at fault.
Officials had said they were examining the electrical system broadly, but while earlier incidents involved components in the aft electrical equipment bay, located behind the wings, Wednesday's involved a forward bay that until now had been largely free from scrutiny.
Rainien said that another blackout is possible because of the weakened electrical system following the quake.
Although this was a widespread outage, neither the cause nor the recovery time should be used to compare it with a deliberate, well coordinated terrorist attack on the electrical transmission system.

Applying an electric current and getting a muscle to jump is easy. (Alessandro Volta jolted a frog's legs 218 years ago.) Peckham is harvesting the body's own electrical signals to control muscles that have been cut off from the nervous system, a process called functional electrical stimulation, or FES. Peckham runs a group called the Cleveland FES Center, a collaboration among Case Western Reserve and two Cleveland hospitals.
The creaking electrical-supply system is starved of investment to carry out urgently needed repairs, as is the water-supply system.
Bigger pixels also emit more current, allowing their signal to swamp the electrical noise in the system.
The pizoelectrics transfer the sound into an electrical system.
"For what it was invented for, the mouse does a good job, " said John Elias, co-inventor of the MultiTouch system and a professor in the Electrical and Computer Engineering department at the University of Delaware.
Entergy told New Orleans City Council members that the company still doesn't know why the device triggered, but the relay has been removed, the dome's electrical system is ready to go and steps will be taken to ensure a malfunction doesn't happen again.
Boeing did some of the safety testing on the 787 battery system, but much of the testing was done by a subcontractor, Thales of France, which made the 787's electrical system, and by battery maker GS Yuasa of Japan, according to a previously released NTSB report.
The crank-handle drives a dynamo through a clever transmission system, and the resulting electrical energy goes straight into a rechargeable battery.
Tom Broadbent has adapted the early river waterwheel electrical generation system for use in high-rise buildings.
But other companies, such as units of United Technologies and other vendors, contribute to the plane's extensive electrical system.
