There is no question the overwhelming majority of ‘mechanical’ energy utilized in this country has as its source the output of Heat Engines, i.e. devices that convert stored solar energy in fossil fuels to ‘mechanical work’.
The New York State Energy Research and Development Authority recently announced a total of $8 million in research grants to help develop or commercialize energy-storage projects.
What is the next breakthrough in battery technology?

MicroPower Direct’s LF500RW Series of SMT 5 W DC/DC converters provides a wide 2:1 input range, tight line/load regulation, output power/overload protection and low noise operation. Twenty-one models operate from wide 2:1 inputs of
A major challenge facing power engineers today is how to overcome a reduction in board space for the power circuitry in commercial electronic products. A quick walk through any electronics retail store will reveal that personal computers have become smaller and even miniaturized which is a trend for many other types of electronic devices.
Portable products increasingly rely on a single 3.7V Li-Ion battery for the energy source. For these and other low-voltage applications, lower gate voltage power MOSFETs improve the efficiency for extended battery life and reduce the heat dissipation involved in switching the loads. In addition, they simplify the design of numerous control functions by allowing direct control / drive.
This year at APEC I moderated a rap session on dealing with the Smart Grid. It had a standing-room-only crowd, and demonstrated how much interest exists on both the technical and political issues involved.

I recently had the great honor of moderating the Smart Grid Rap Session at this year’s Applied Power Electronics Conference (APEC). It brought home to me that in addition to the technical challenges facing the power industry, there are also political issues that must be addressed as we move forward. The old political arguments around power revolved around NIMBY issues about the location of power plants...
