Troy from the Hudson River

After fighting some pretty strong winds, a severe thunderstorm threat, and some heavy rain, I finally made it to Troy. I was running a little late, so I decided not to paddle into Downtown Troy.

June 1, 2020 Morning

Good morning! Happy June 🍹and Happy Monday ! Dairy month and Pride Month. I’ll have to hang up my rainbow 🌈 flag when I camp. Three weeks to Average High is 80 πŸ–. Mostly sunny and 46 degrees in Delmar. Calm wind. A pretty nice morning.

Today will be mostly sunny 🌞, with a high of 67 degrees at 4pm. Seven degrees below normal, which is similar to a typical day around May 9th. Light and variable wind becoming northwest 6 to 11 mph in the morning. Winds could gust as high as 21 mph. A year ago, we had mostly sunny skies. The high last year was 81 degrees. The record high of 94 was set in 1918.

Definitely going to be a nice day for working outside. 😎 After my morning walk 🚢 I’ll clock in πŸ•’ and take the laptop out back and enjoy the nice sun. β˜€ Midday I’ll go down to the library to work and then maybe after lunch, πŸ” out to Five Rivers to work and then walk and bird 🐦 watch after five.

Solar noon 🌞 is at 12:54 pm with sun having an altitude of 69.5Β° from the due south horizon (-1.3Β° vs. 6/21). A six foot person will cast a 2.2 foot shadow today compared to 2.2 feet on the first day of summer. The golden hour πŸ… starts at 7:45 pm with the sun in the west-northwest (295Β°). πŸ“Έ The sunset is in the west-northwest (302Β°) with the sun dropping below the horizon at 8:27 pm after setting for 3 minutes and 24 seconds with dusk around 9:00 pm, which is 47 seconds later than yesterday. πŸŒ‡ At dusk you’ll see the Waxing Gibbous πŸŒ” Moon in the south-southeast (166Β°) at an altitude of 42Β° from the horizon, 226,405 miles away. πŸš€ The best time to look at the stars is after 9:45 pm. At sunset, look for partly cloudy skies πŸŒƒ and temperatures around 62 degrees. There will be a northwest breeze at 7 mph. Today will have 15 hours and 6 minutes of daytime, an increase of one minute and 15 seconds over yesterday.

Tonight will be mostly cloudy πŸŒ₯, with a low of 49 degrees at 4am. Four degrees below normal, which is similar to a typical night around May 23rd. Northwest wind 5 to 7 mph becoming light and variable after midnight. In 2019, we had mostly clear skies in the evening, which became partly cloudy by the early hours of the morning. It got down to 49 degrees. The record low of 39 occurred back in 1971.

Right now, a split verdict on the weekend. πŸ˜• Saturday, a chance of showers. Mostly sunny, with a high near 82. Chance of precipitation is 30%. Maximum dew point of 57 at 9am. Sunday, mostly sunny, with a high near 74. Maximum dew point of 47 at 6am. Typical average high for the weekend is 75 degrees.

I am probably going to go up to Speculator at 5 AM on Thursday morning, β˜• work from there Thursday and Friday, get some beach time and fishing 🎣 in over the weekend. That gives me three nights camping β›Ί in that site with the good cellphone reception for work on Thursday and Friday. Not sure if I’ll bring my kayak, it might be good for fishing but it’s a pain to load and unload. I still want to get to Schoharie but depending on how Coronavirus goes maybe in a few weeks the Mine Kill pool will open 🏊 or maybe thats too optimistic based on the beliefs of the politicians.

As previously noted, there are 3 weeks until Average High is 80 πŸ– when the sun will be setting at 8:36 pm with dusk at 9:11 pm. On that day in 2019, we had mostly sunny and temperatures between 80 and 55 degrees. Typically, the high temperature is 80 degrees. We hit a record high of 95 back in 1954.

60 Hz Alternating Current Power Kind of Sucks.

The truth is …. 60 Hz Alternating Current Kind of Sucks

In North America, 60 Hz is the standard of alternating current. It was a rather nasty compromise between frequencies, chosen as a “sweet spot” between:

  1. Line losses due to high-frequency currents – The higher the frequency of AC the greater loses due to impedance caused by the voltage and current becoming out of sync due to the induction created by the line (time it takes for the magnetic field to appear and collapse on the wire). It’s not practical to send 400 Hz over any length of wire due to losses.
  2. Size of the transformer needed to step and step down voltage – The higher the frequency of AC, the smaller the transformer needs to be. The magnetic energy in alternating current “exists” in the alternating voltage, so if the voltage is alternating faster, a small transformer can move more power.  Smaller transformers use less copper, they’re cheaper to build, and they’re generally more efficient.
  3. The ability to power light bulbs with minimal smoothing. Incandescent bulbs can be powered directly from 60 Hz alternating current, as it takes more then 1/60th of a second for an incandescent bulb to cool down enough to notice the crossing of zero point. Additionally, with 60 Hz power, a relatively small capacitor can be used to smooth out rectified power to drive an LED light, for fixtures that use a large number of LEDs in series.
  4. The ability to power low-power AC motors. 60 Hz alternating current can and does drive many AC motors, but it does require relatively large motors compared to motors operating at 400 Hz. Not only do 60 Hz alternating current motors require much larger coils then 400 Hz motors, they are less efficient.

Airplanes traditionally use to 400 Hz power, as it saves quite a bit on weight for their electrical motors and transformers. Likewise, traditional automotive alternators generate power in the 400 Hz range, before going through a bridge rectifier to convert 3-phase AC output to direct current. But transferring 400 Hz power, or for that matter boosting and bucking high-current DC can be difficult and prone to electronic failure compared to traditional mains frequency transformers.

But increasingly, we are seeing more uses of high frequency alternating current and direct current, especially in consumer devices. Most modern electronics are powered by switch-mode power supplies, which use high-frequency transformers (as high as 1,000,000 Hz) to safely step down voltage in an isolated fashion. More motors today are driven using inverters, which similarly create a higher-frequency current to provide more power with loss copper and less losses. Controlling the frequency of the current, allows motors to be precisely controlled in their speed, it’s more efficient and accurate then simply chopping off part of the sine wave using thyristor as was done in the olden days to control motor speed.
