Does “Moore’s Law” hold for Solar Power? In New Jersey, between 2001 and 2010, we went from a total of six systems with a combined capacity of 9.0 KW to about 7000 systems with a combined capacity of 211,000 KW or 211 MW. This is illustrated below. This is the “hockey stick” curve of exponential [...]

Tweet In Part 1, I criticized “How to Really Save the Economy“, an op-ed in the New York Times, published Sept. 10, 2011. So how do we really save the economy? “One of the best kept secrets in New York City,” I wrote, “is the existence of a 40 kilowatt (KW) photovoltaic solar array on [...]

Tweet Bucolic? Pastoral? Looks that way, but looks can be deceiving. First of all, there’s Indian Point 1. Then there’s the water issue. Other issues are waste and national security. Indian Point 1 Brought online in August, 1962. Shutdown in October, 1974. Spent fuel is stored on site. Scheduled to be closed in 2026. Operated [...]

Solar power’s incremental steps forward keep coming faster and faster, and not on a single vector: large arrays to power the grid, specific installations where wiring is inefficient or impractical, and for small devices. Cassie Rodenberg, writing at PopularMechanics.com, writes about another step forward with solar power for relatively small devices. From Solar-Powered Circuits Breakthrough [...]

Solar Balloons can power remote areas and quickly provide emergency power in disasters. Joseph Cory, of Geotectura.com, and Pini Gurfil, his research partner in the Haifa Technion, Haifa, Israel, are developing the balloons. Helium balloons floating above the trees or tethered to the roofs of buildings, can provide more power in less space and at [...]

The same messages can be communicated by signalling the letter "K" in Morse code via signal lamp. (While a proper signal lamp may be ideal, a flashlight, probably best employing red LEDs, will certainly fit the bill).
In Morse, the letter "K" is represent as Dash - Dot -- Dash.
The ICS also has a subset, the Medical Signal Code, which uses three-character phrases to communicate brief medical messages.
