You need your head examined!
- Category: Ramblings
My wife often tells me that I need my head examined, and that’s exactly what I was doing a few weeks ago at the dermatologist’s office. My semi-annual all-over skin check-up (all-over except the nether regions, that is) had revealed a suspect area, and a biopsy revealed it was indeed skin cancer and must be removed. It’s no big deal, but how did it get there and could I have prevented it?
The surgery is a time-consuming affair that involves removing a layer of skin and then sending you off back to the waiting room while they ‘scope it to see if they got all the bad bits. If not, back you go in to have another layer removed, and so on until you’re given the all-clear and they stitch you up. Most of the occupants of the waiting room were sporting large, blobby, ultra-white dressings somewhere above the shoulders, and many of them on their left side. That’s because we drive on the left in the USA. Yes, seriously.

Other than the strange and fruity wardrobe, Robin Hood and his Merry Men had a noble agenda in England back the middle ages, i.e. rob the rich and give to the poor. They probably kept a little back for themselves for expenses, i.e. something to make the men merry plus some bling for Maid Marion, but overall they fought a worthy fight for social justice and equality. Fast forward a few centuries to 2018.
Our modern-day Robin Hood wannabe comes in the form of Robert Lighthizer, the US Trade Representative (USTR), who recently announced that tariffs will be imposed on virtually all silicon-based foreign-made solar cells and panels entering the US effective February 7, 2018. This is a four-year program that starts this year with a 30% tariff, and which then decreases by 5% each year ending up at 15% in year four.
Now, unlike the anti-dumping and unfair subsidy tariffs that have been in place since 2012, these new tariffs are not aimed exclusively at one or more countries of manufacture. Those tariffs originally singled out China, but the Chinese manufacturers then started country-hopping and ended up producing solar panels in other countries to avoid the stinging tariffs when imported into the US.
Not to be caught out, Mr. Lighthizer has taken a different tack this time around and has herded all major nations world-wide (there are exclusions for certain “developing countries”) into the dock for judgment and punishment. This time there is no country-specific element and it’s the US versus the rest of the world.
The issue at hand here is whether foreign solar companies who are able to import solar products into the US at less cost than the available domestic equivalents have an unfair advantage in the solar marketplace. The plaintiffs: Two large US-based solar companies.
The crying started in May last year when Suniva, which was 63% Chinese owned and now bankrupt, petitioned the International Trade Commission (ITC) that “increased imports were a substantial cause of serious injury to the domestic industry”. Suniva was later joined by SolarWorld Industries Americas, then a subsidiary of German owned and now reorganized SolarWorld Industries AG.
After much deliberation, our Robin Hood of Washington Forest has decreed that US solar manufacturers must have some sort of “safeguard” in order to compete fairly against foreign solar manufacturers, and these latest tariffs are the result. Whether this is a correct and/or fair judgment is up for debate, but I for one don’t quite understand how this is going to help the US solar industry much, if at all.
Paradoxically, those foreign solar manufacturers will not be paying any penalties, and our Robin Hood will not be robbing them and giving the proceeds to the now defunct plaintiffs. No, the tariffs will actually be paid by those US companies that import foreign solar products, and the burden will then be passed on down to the end user.

We were the first house on our street to get a telephone when I was a lad in England. We didn’t pay for the installation though, that was arranged by the hospital where my mother was something important in the operating theaters, and she was often called out for emergencies. I guess they got tired of sending taxis and having the poor drivers going bonkers trying to wake our sleeping household.
Ours was a line that we shared with another unknown party, and I soon learned that if the phone tinkled when you walked past, you could carefully put your hand over the microphone and lift the receiver and hear the other parties’ conversation. We never knew who the others were, and their conversations were quite unexciting and boring, so it was more like eavesdripping than eavesdropping. I heard tales that in the US there were sometimes up to ten households on one party line, which I imagined to be far more interesting.
Our first phone had no dial. You had to pick up the receiver and wait for an operator to come on the line and say “number please”. Our number was 1968, which was quite a novelty when the year 1968 rolled around.
A Heated Conversation

We occasionally get asked whether it is possible to run a reverse-cycle marine air conditioner (heat-pump) when the water surrounding the boat is at freezing temperatures. The answer to that is “yes, it is indeed possible”, but is it a sensible, safe, and reliable way to heat a boat in those conditions?
Most of these inquiries come from live-aboards up north, although we may well be hearing from some in Florida and other southern states in the days to come once this arctic blast hits down there also. We hear that many marinas are now stipulating that plug-in heaters are prohibited, citing insurance issues, including even the ceramic and oil-filled radiator types, which seems a little overly precautious to my mind.
For a really cozy cabin you could install a diesel-fired forced air or circulating water system, but these are expensive and complex installations that require strict adherence to the manufacturer’s instructions in order to prevent potential ventilation, exhaust, and noise issues. Then, they sit idle for half the year.
So, your vessel is sitting in freezing/frozen water and you want to use your reverse-cycle air conditioner to heat the boat. You won’t get that much heat out of it, but once it’s up and running and you have a warmish cabin, you should get around 30F higher air temperature at the air outlet than at the inlet. Just don’t stop it once it has started, as it will take forever for the system to start producing any useable heat again. A cold compressor will suck up all the heat being produced by the system for the first 15 to 30 minutes until that heavy hunk of metal has had a chance to heat up.
