Two weeks ago, I described the chasm before mass-market electric vehicle adoption. The chasm, as shown in Figure 1 and depicted in the EV Rant as a moat, is the gap between enthusiastic nerds and mainstream curmudgeons. I'm often among the mainstream curmudgeons, but not always. I could be considered an early adopter of smart thermostats and cold-climate heat pumps purchased 11 and 7 years ago, respectively. Figure 1 Market Adoption Curve For automobiles, I have gone out of my way for years, decades even, to find ones with manual transmissions – why? Energy efficiency, for one. There is less…

In September, I wrote a series of five Rants on data centers, a concise and comprehensive collection that might just be the Data Center Digest you never knew you needed!   Chip and server power density, cooling, and projected GW load growth. Data center facilities from modular to 200 GW-plus hyperscale. Efficiency ratings and power usage effectiveness scales. Data center HVAC (minus the H because that's not required) options. Future power shortages and power supply complications. The anticipated load growth is due to artificial intelligence, which most professionals believe will explode—and so does Wall Street. Table 1 lists the current…
