Fixing the ignition system on the F-250

I have a diesel 3/4 ton truck, a Ford F-250.  The previous owner had an anti-theft and alarm system installed on it after he purchased it.  The anti-theft system began giving me trouble, and at one point, I had to disconnect the alarm in the middle of the Wal-Mart parking lot, because it wouldn't stop making racket.

The Cub Cadet Mower

I own a couple of riding mowers.  I use one for the lawn, and another one for the rest of the property.  The mower that goes out in the field is the Cub Cadet.  It gets beat up pretty badly, because I often hit rocks, stumps, and branches that are not visible in the grass.  Sometimes I high-center it and the blades whirl around in the dirt and gravel until I can get them stopped.

For those waiting with bated breath for the next post...

It shouldn't be too long, I'm just taking a summer breather.  Been a lot going on in the real world!
Back soon!

Nearby Radiological Emergency

This past week there was a radiological emergency at the Hanford Reservation.  The event caused a site-wide alert to shelter-in-place.  Very exciting.

Evaporative vs Refrigeration cooling

Once upon a time I lived in the Mojave desert.  It's the most arid place that I've ever been to, although from what I've seen, it's nowhere near as dry as the Sahara desert.  In the summer months, the sun is intense and the heat is brutal.  Any time you live in a desert, it's a great idea to try to keep the inside of your house from getting as hot as the rest of the desert!

Garage door alarm

I'm taking a brief break from Hydro failures and the depressing loss of life that goes along with it.  I have a post on the Johnstown flood in draft, and will get to that shortly.

Meanwhile, I thought I'd put up a post about a practical home improvement.  I thought of the idea after reading this article.

Hydroelectric near-miss: Oroville Dam ***Update #2***

Ha!  This has been serendipitous...  I've been doing a series of posts about dam failures and near misses.  The posts are here, here, and here (with another post on the St. Francis dam in draft) - when lo and behold, we have an ominous near failure in real-time on the evening news right now.

Hydroelectric Near-Miss - The Glen Canyon Dam

The Glen Canyon dam is a very large dam on the upper Colorado River, on the northern border of Arizona.  The Glen Canyon dam impounds the Colorado River in a man made reservoir named Lake Powell.

Below, Lake Powell.  The Glen Canyon dam is at the bottom left, under the words "Lake Powell".

Nuclear War

During the recent presidential election, there was a great deal of Cold War-era rhetoric, and it un-nerved me a bit.  I wasn't worried about myself - I've had a reasonably long and healthy life.  I was un-nerved for our daughter.

I was hopeful that the belligerent words would calm down, and for the moment, they have.  But I suppose those that set them in motion might do so again.  Even so, there are often world events that are of concern.

Here's the thing:  The nuclear genie is out of the bottle.  I never dreamed a civilian nuclear reactor would melt down after the wake-up call of Three Mile Island.  Nevertheless we've now had Chernobyl and three of the Fukushima reactors contaminate large areas.  In fact, there is ongoing groundwater contamination at the Fukushima nuclear site...  That's plenty of contamination, even without intentionally detonating nuclear weapons.
