I published a post on the "Alice," a fully electrically powered airplane being designed and built by the Israeli Company "Eviation." The Alice is being promoted as a "9+2" airplane, that is, two pilots flying nine…
Am I safe to break in?
I saw a commercial for the Google Home Speaker in which the spokesperson was touting the speaker's ability to scare off burglars by playing the sound of a barking dog. I realize there are multiple systems out there to achieve…
Solar energy is GREAT but…

As is pretty clear from previous posts (and despite my current vehicle, airplane, and travel itinerary), I'm a very big fan of renewable energy. And thus, also a fan of solar power. But sometimes solar isn't…
Energy Vault Revisited
Image credit: Energy Vault
Two posts back I discussed Energy Vault, a "Swiss-U.S." company whose concept for energy storage is based on the use of tower cranes to stack concrete blocks. The blocks would be raised with electric motors to…
Eviation Alice

As I've mentioned in quite a few previous posts, I'm a pilot by avocation and a dedicated follower of all things aviation. My YouTube feed recently decided that I'd be interested in the Eviation Alice, an all-electric…
Energy Vault: A mashup of two of my interests

My occupation is as an executive in a firm that provides materials testing, inspection, consulting, and engineering in the construction space. We deal with all aspects of the built environment with the exception of single family…
Requiem for LightSail Energy

I've published multiple posts concerning LightSail Energy and its Chief Science Officer, Danielle Fong. I was enthusiastic about the the Lightsail Energy compressed air energy storage technology concept, wherein a water mist was to have been…
My airline fuel use
Undoubtedly to the disdain of those who seek to minimize energy use and, in particular, energy use that involves travel via the burning of fossil fuels, I do a significant amount of airline travel. And, beginning in August of 2017,…
Charging the Tesla class 8 semi
This is my third post regarding the Tesla class 8 truck. The first covered the range claim and the consequent weight ramifications. The second covered the cost. And, of course, the numbers were my estimates only. In this post I'll consider…
Tesla class 8 truck, part 2

In my previous post I estimated the weight penalty imposed by the need for a battery pack that will enable the Tesla Truck to have a range of 500 miles. Next, I'll take a look at the…
The Tesla class 8 truck

Well, it's been a long time since my last post and I promise to be more.... Oh, hell, never mind. Anyway, to those who know me, it will come as no surprise that I am an admirer…
Pavegen, up close and personal

I was again in Washington, DC (actually, National Harbor, Maryland, just down the Potomac) last week for the annual (and perhaps last?) arpa-e Energy Innovation Summit (about which, more later). But I had learned that one of my…
From the "duh" department…
In my day job, I am an executive in a firm that provides consulting services, materials testing, and construction inspection. We don't work in the area of single family housing but, other than that, if it's being built, we want…
Once again with Pavegen

(Note: the zombie image applies both to my blog and to the subject of this post.)
Pavegen, a Company that I've looked at before (see here and here) is still around and, apparently, thriving. Pavegen designs, manufactures,…
A Post Election Day Note to Conservatives | Coyote Blog
A Post Election Day Note to Conservatives | Coyote Blog:
'via Blog this'
What Warren Meyer (a staunch "small l" libertarian) said. But, to make it easier, I'll paste it here:
"Dear Conservatives: As you wallow around in your election-day…
arpa-e 2016 notes part 1
Having spent six days traveling to, attending, and returning from arpa-e 2016, it's time to start chronicling some of my thoughts. At the broadest level, the summit was very well attended, much better than last year. As is typical, the…
Off to arpe-a 2016

I'm rather shocked to find that this is the sixth (!) arpa-e energy innovation summit that I've attended. I intend to blog about my adventures here and, in particular, about some of the energy storage sessions as…
The end of an era
In September of 2005, gas prices rose abruptly enough that I stopped driving as I had as a teenager in my Plymouth Roadrunner Detroit muscle car and started to do my best to squeeze every possible foot out of each…
Marco Rubio and what money can buy
It should come as no surprise that Presidential candidate Marco Rubio is at the forefront of an effort to stymie local municipalities' efforts to prevent complete monopolization of broadband by Charter Cable, AT&T, and their ilk. I'm all for private…
More green hype (though, apparently, well-intended)
Image credit: Wikipedia
It's been a while (and this isn't my first such apology) since I've posted an article. The long-awaited article (actually, articles) on the cost effectiveness of renewable energy with storage as base load and/or dispatchable electrical energy…
LightSail yet again

This will be a short one. LightSail Energy, a startup with innovations in compressed air energy storage, has already appeared in my writing twice, the most recent being after co-founder Danielle Fong was generous enough…
How much storage is needed, part 4
Image credit: Unknown
My previous post in this series related some of the drawbacks of my simplistic analysis, the objectives I want to achieve, and a sketch of the methodology I've employed. Briefly, I've used a Monte Carlo simulation (yes, I linked…
Rocks on rails

In an earlier post I covered a concept of utilizing a massive rock piston over pressurized water to store energy. Another firm uses a concept analogous to pumped hydro storage but, rather…
How much storage is needed, part 3

Previously, I imported the daily mean wind speed recorded at Dalhart, TX (at the airport, I assume) for the period beginning January 1, 2000 through the most recent day recorded in Wolfram's curated weather data. I adjusted…
How much storage is needed, part 2
In my previous post, I started the process of attempting to estimate how much storage would be needed in order for wind in a favorable part of the US to be able to provide a stable source of base load…
How much storage is needed?
I've published several posts on energy storage but yet have not dived into any of the practicalities of what might be needed for various scenarios. While that's a very broad topic that could involve everything from what a homeowner might need to…
A box of rocks?
I've blogged on a few occasions regarding energy storage, most recently a "LightSail Energy redux" (though I'll be updating that in the near future to revise an inaccuracy with respect to LightSail's ability to produce commercially in their existing Berkeley…
While I procrastinate in writing about more important things…
Physicists (one of which I am not) are quite concerned about units and dimensions and use dimensional analysis for a variety of purposes. And if the units in an equation don't match in all terms and across the equals sign,…
Kunstler gets serious
Typically, I ignore James Kunstler and, in fact, I posted the reasons for this. And this is despite that fact that I agree with many of his positions, particularly with respect to the exigency of our energy situation. But his…

It's difficult finding post topics if I insist that they meet certain criteria: can't take so long to research and write that my family/work/school life is disrupted; must be something about which I have some…
