My Experiment to Compare the Power Consumption of Heat Pump Mode Versus Energy Saver Mode
Over the last eleven days I ran a series of experiments which limited the number of variables to two: heat pump modes and water usage levels. Rheem insists that their Energy Saver mode is more...

How to Save a New Schedule
After opening the app (EcoNet version 6.x, not the slight variant called Rheem EcoNet nor the other slight variant called Ruud EcoNet), click the central area of the first screen...

This series of three articles is about my quest to optimize the energy efficiency, operating cost and indirect pollution effects of a new heat pump water heater using the controls in Rheem's EcoNet...
Suppose that you're checking some of the key settings of your Fujifilm GFX 100S by looking at your custom "My Menu" tab in the main menu area of your camera and you see this (this is how mine is set up):
What kind of RAW file will the camera be saving when you trip the shutter?

As "Trump" is German for Bullshit.
Little Vladimir, the world's #1 terrorist, strikes again, proving that the power-hungry, skilled liar is humanity's worst enemy.

This face reveals plainly the quintessence of the thing that National Defense is for. The life-long, KGB spy master has finally come fully into his own, but his character has never changed and has been as obvious as the contrived non-expression on his face ever since we’ve known him.

Election fraud is alive and well in America, and has been thriving for decades if not longer. It's millions of times bigger than voter fraud. And this appalling fact means that American elections absolutely are rigged. Trump was right about that, but of course he was lying about who was rigging...
On January 17th, 2022, photographer Matt Payne published on his site the podcast titled "Printmaking In Landscape Photography - A Panel Conversation". This is a conversation organized by Matt with three photographers known for their special work in photographic printmaking: Michael Strickland,...
I’m decidedly not a virologist, but I do pay attention, and it strikes me that a glaring omission continues to be made in explaining to us all about how viral infections and vaccines work.
A viral infection is a race — a race that starts when a virus gets into you and successfully enters a cell,...
There has been and continues to be a long-standing problem with the way that methane is described as a greenhouse gas (GHG). The proper way to describe the strength of the various GHG’s using a pound of CO2 emitted (or a pound in the sky) as the benchmark would be to say A) How much heat is...
The fate of the American republic, and therefore of democracy worldwide, hangs by a thread. That thread will either prove to be a lifeline or will be cut, most likely by next Monday, January 17th, 2022.

This L-plate from Rogeti (pictures below), a new player in the camera L-plate market appealed to me with a couple of aspects of its design — the diagonal brace for stiffening of the vertical arm of the one-piece plate (my preference to a full-wide, two-part plate design) and the inclusion of a...
The new book of this title, by perhaps the most dynamic and accomplished trio of climate saving heroes on the planet, provides the best blueprint for what all of us together and each of us individually can do to turn the tide and win the climate battle. But there is no time to waste.

There are only two things that one needs to know to thoroughly understand our 45th President.
The first is simply that he harbors good will toward no one.
The second is that his one great purpose in life is to prove himself to be the ultimate "winner" or “killer,” in the lingo of his family,...
Lawrence Lessig has another great new project to help save the republic. Ending the winner-take-all practice of the Electoral College process will return presidential elections to the principle of one person one vote and reclaim this most fundamental aspect of democracy from the catastrophically...

My Test Results
Testing primarily with two Epson wide format printers, the Stylus Pro 9900 and the SP 11880, I have run more than 150 experiments, carefully conceived to reveal which methods of printing from Photoshop CS5 on the Mac work correctly and reliably so.

For some time it has been clear to me that the changes we're seeing in the arctic, especially, prove beyond a reasonable doubt that we have long since passed critical major tipping points in the Earth's climate system. Perhaps the most important surprise from the...

On Friday the 17th of August, 2007, a news report on NPR revealed that the extent of the Arctic sea ice had, surprisingly, just reached a new all-time low extent (area), a full six weeks ahead of the expected seasonal minimum, meaning that the low ice extent for 2007 would be a record low by a...

A new study conducted by NASA, authored by 48 scientists, warns that the so-called tipping points for the Earth's climate are much closer than previously thought. The critical thresholds for atmospheric CO2 levels may be "much lower than 450 ppm", meaning that we may already be beyond the...
