RE: A lot more than we think?

WOW! Tons of members are Latino overlanders. Phenomenal group. "¡Todos nuestros respetos a este gran conductor que es capaz de maniobrar con gran agilidad y destreza! ¡Nos encanta y envidia!" ....you've got to see this tow trailer jockey in action in the video at that Facebook site. He can drive better in reverse towing an 18 foot tow trailer than most drivers can drive forward towing nothing !

RE: BradW's photo links on the Truck Camper Forum

I remember when photo bucket did that. They caused a lot of damage. People say photo bucket is back, but I would never trust them after the stunt they pulled. Yup. Photobucket victim here. I pulled all my photos off that ~!***, but separating photos from a detailed article or trip report is about as useful as operating a vehicle without wheels under it....

RE: Deleting and Closing A Thread

Chris: Correct. I can't argue with that. The EU will likely fall apart, too. Its every country for themselves vis restrictions of every pandemic-related strategy. I would hope that some land crossing coherence could be worked out, at least between / vis-a-vis the US and Canada.

RE: Deleting and Closing A Thread

Then you look at the "over the top" Canadian restrictions (I am not Canadian, they can do what they choose). The covid travel restrictions are just plain BS. Until freedom of movement is restored, your government will become part of your decision in where you travel to. ....Canadian here. And, a proponent of rapid vaccinations deployment. Agree that Canadian Fed travel measures are, um, unsophisticated, and far too generalized. With all the vaccines deployed in the US and Canada (in Canada: 6.3 million doses), no "travel vaccination passport" plan yet exists for Canadians traveling southbound by road, so this precludes any Canadians RVing to Mexico. Even returning Snowbirds driving into or flying back to Canada who have had their entire 2 shot course of Covid innocs, are not recognized by Canadian authorities as "safe" (report this week here). Both Florida and Texas have banned "vaccination passports" for proving vaccination inter-State. But this is different from requiring international (Mexico? Canada?) vaccination passports.

RE: Canadians: 65+ are getting vaccines now

BobsYourUncle: MANY thanks for your follow up! Excellent. Ground crossing looks like no $2000 / $3000 penalty for Canadians. Perhaps more Canadians crossing by land will add to this data. Moisheh: Great news for you. Glad to read you've had the vaccine. Everyone else, and US neighbors, we here are super appreciative of any vaccine your President can and may release to Canada. Beautiful gesture. Good friends? You bet! We should be getting our jabs in 2 weeks for our age group in Quebec, with official "stamp" that gets affixed into our vaccine card. More later... Cheers, Silver

Canadians: 65+ are getting vaccines now

Good morning All: With us 65+ now being vaccinated in Quebec, I find the Federal rules for land border return extremely, um, confusing in Canada. Have any Canadian returned from Florida and other southern snowbirding States, and if so, what were your experiences driving back, and what quarantine procedures were you instructed to follow upon arrival at land border crossings?? I realize that some Canadians snowbirding in Florida had gotten at least 1 vaccine shot. If any vaccinated Canadians returning by road to Canada, what were your quarantine instructions at the CBSA ? I'm hearing that returning AIR travelers are of course required to register with a Federally-approved quarantine hotel, and obtain PCR 72 hours before arrival; however, the rules for returning-by-road Canadians are as clear as mud. Moisheh (an over-the-land hauler): I assume that you had gotten your 1st jab long ago? Just about everyone in Quebec 70+ has had their vaccine by now.

RE: Exxon lost $20.1Billion - the beginning of the end for oil?

....consumption. Where has it been? Where is it going? One of the most respected sources analyzing the global energy landscape, is the think-tank RFF. They put out something called the GEO (global energy outlook). In the 25 year period from 1990 to 2015, the Planet's energy consumption increased by just under 200 quadrillion Btu ( qBtu ) of the gross consumption of 550 qBtu. Their forecast from now-ish to 2040 suggests only a modest increase in consumption ( 80 qBtu growth). I've seen unrelated estimates of oil prices climbing very slowly to well over $200 USD per barrel WTI by 2050-ish. Presently, there are appx ~ 30,000 aircraft (military and civilian) capable of flying in the World today. By appx 2040, the prediction is 65,000 -ish aircraft in the air. Every one of these (and, future) aircraft will run on aviation fuel (a petroleum byproduct). Presently, there are appx 101,000 locomotives operating on Earth at end of 2017. Not all are diesel, but most are. How many steamships and power boats exist and operate on Earth today? Appx 36 million of them, running on diesel or gasoline; steamships alone serving more than 25,000 ports. Until we figure out how to run jets, turboprops, diesel locomotives, steamships all off nuclear (a few run on electrics already), oil will easily maintain its status as "the World's most prolific single fuel source", probably till at least appx ~~2090. This, of course may be mitigated by what are called ACS (ambitious climate scenarios) calculus.

RE: Border crossings about to get even worse

The agent wanted me to speed up but I didn't. .....there is good reason to minimize biological exposure to high energy X-ray. On edit: partly deleted "DHS' X-ray scanners could be cancer risk to border crossers" here--> The Electronic Privacy Information Center (EPIC, of "EPIC v. the NSA" fame) obtained the specifications on the San Ysidro genre of X-ray scanners through an Freedom of Information Act. Look it up. The document is partially redacted, of course. EPIC v. HLS. In 2016, EPIC v. TSA in DC Appeals Court link-->commenced in I believe 2017, on forcing TSA to allow passengers at airports to undergo full body pat-down as an alternative to backscatter AIT walk-through. In Europe, "passengers are given the right to opt out from a control with scanners and be subject to an alternative method of screening". And, further, "In order not to risk jeopardizing citizens' health and safety, only security scanners which do not use X-ray technology are added to the list of authorized methods for passenger screening at EU airports. All other technologies, such as that used for mobiles phones and others, can be used provided that they comply with EU security standards." link-->

RE: It’s been a good run

Start loosing capacity at 10 years mark, but I used couple of them till 12 years of age. ....my old Maxtanks (AGM) are still in operation at 13 years last year (2020). I suppose replacement will be needed soon.

RE: 2019–20 CORONAVIRUS PANDEMIC POSTINGS

I wonder how the FDA would deal with: Using vaccines outside of the EAU (mixing vaccines, not following dose timings, etc) Providing an EAU for mixing vaccines Adverse reactions when 2 pharmaceutical companies are involved ....didn't the Hep B "boost" prove to be a successful heterologous endeavor? Also, more recently the Sputnik vaccine uses heterologous boosting. AstraZeneca's prime boost interval was recently bumped to 3 months. That one is interesting, as it turns out that the efficacy of AstraZeneca's single dose is remarkably high, completely unpredicted.

RE: 2019–20 CORONAVIRUS PANDEMIC POSTINGS

I'm not saying the use of 222nm for sterilization should be avoided; I am suggesting that implementation of this in public spaces should be carefully thought out so as to avoid unintended consequences. A good example of its use might be interior of the HVAC air return ducts. Agreed. Thank you for the links; I will read through every one of them. Thanks. Also, halogen, incandescent and fluorescent lighting all give off varying intensities of UV. These are ubiquitous, found in every building and space installed over the past ~90+ years. Drastic decrease of carbonyl group after the loss of ether in PADC exposed to 222nm UV photons Radiation Physics and Chemistry Volume 157, April 2019, Pages 60-64 On edit: ....this RPC article was interesting. However, PADC (thermoset plastic used for eye glasses lenses) is an extremely effective UV-C blocker, especially at 254nm to 280nm and lower. It seems to be almost unaffected by UVC (even at 102uJ/cm2 for long duration PADC is quite impressively stable). ....on to next article.... Degradation of Bisphenol A in an Aqueous Solution by a Photo-Fenton-Like Process Using a UV KrCl Excilamp Int. J. Environ. Res. Public Health 2021, 18(3), 1152 ....interesting. Especially in the realms of BPA profusion and toxicity to marine environment! "Direct UV irradiation without persulfate (direct photolysis) showed a relatively low BPA degradation rate so that it was converted by 84% after 60 min treatment whereas the DOC removal reached only 13% after 4 h of exposure. No degradation was observed in the presence of persulfate without any UV exposure (data not shown)." ....however, without a photoreactor (KrCl excilamp) and persulfate, there was little degradation of BPA bombarded by UVC (at the rate published). This is really bad news for any natural degradation of BPA floating out in the oceans (forget about toxic byproducts cutting loose from degrading BPA out in the marine environment!).... But I'm still with you vis ongoing research into 222nm as a sterilization agent and negative issues oxidizing the myriad plastics in the sterilization "space"....

RE: 2019–20 CORONAVIRUS PANDEMIC POSTINGS

It was my understanding that Canada does not have the ability to manufacture a vaccine at the present time and must rely on other countries for the vaccine. Correct. Montreal has a facility called the Royalmount. It is a Canadian Federal Government facility for experimentation and not a vaccine manufacturing facility, and run by the Canadian National Research Council (NRC). Retrofits are being done to upgrade the facility to vaccine production capability. The Royalmount presently does cell culturing, microbial fermentation, molecular modeling, and antibody production (bioprocesses engineering). And, primarily human health therapeutics (pure) research. So, it made sense to rapidly convert this facility to vaccine manufacturing. the Royalmount-->

RE: 2019–20 CORONAVIRUS PANDEMIC POSTINGS

How should 222nm UV light disinfection be employed inside buildings to disinfect while minimizing the damage it will do to the interior building materials never designed to withstand the damage caused by UVC? (UVC degrades polymers/plastics) ....I am unaware of any damage that could occur to polymers and plastics with 222nm continuous-use TLV. The excimer filtered output would be set to FDA threshold limit value (see the link to above Nature research) far below any values that could damage human tissue let alone plastics. In addition, ASDUs (air and surface disinfection units) have been used for years in all manner of environments, continuously, to disinfect all manner of man-made materials, including medical devices. Can you point to any materials research that demonstrates that excimer-produced far ultraviolet filtered ultra narrow-band 222nm output at 1.2 to 1.7 mJ/cm2 of 222nm light degrades "plastics" or polymerized materials faster than said plastic's natural environmental oxidation?

RE: 2019–20 CORONAVIRUS PANDEMIC POSTINGS

The science journal, Nature Research in its Scientific Report, shows in its Inactivation of human coronaviruses after exposure to 222 nm light in aerosols infectivity assay results section, that, "The severity of the 2020 COVID-19 pandemic warrants the rapid development and deployment of effective countermeasures to reduce indoor person-to-person transmission. We have developed a promising approach using single-wavelength far-UVC light at 222nm generated by filtered excimer lamps, which inactivates airborne viruses without inducing biological damage in exposed human cells and tissue11–18. The approach is based on the biophysically-based principle that far-UVC light, because of its very limited penetration in biological materials... " Read the entire research paper here--> Why this technology has not been fast-tracked last year into every public facility, government building, and every hospital on Earth is a mystery to me. I know it has been installed into a handful of airports in the USA (and, one in Canada: Vancouver international), and in a handful of hospitals (John Hopkins, being one). The cost to install this is miniscule in comparison to the billions (probably trillions) that will be lost to the economy AND, the millions (tens of millions?) of human lives lost to Covid (and, the flu!) over the next 2 to 5 years.

RE: New Border Regulations

As far as I can tell (searching all Canadian carrier flights with US continental destinations), I can see very few flight cancellations next week. I did see numerous Canadian airlines with rather unusual departures-only FROM Mexican international airports. I suspect that Canadian airlines are flying to Mexico (nearly) empty, and loading up with repatriating Canadians IN Mexico. ....I'm following all passenger flights World-wide, real-time, and focusing on incoming/outbound flights from Canada/USA/Latin America. Anyone in Canada can actually jump onto ANY US air carrier departing from any Canadian international airport, and with one hop, get to any Canadian sun destination, no problem. Also, the "reported" $2000+ CAD cost to returning Canadians (and virtually anyone coming into the country by air) can vary, depending on how rapidly the Canadian airport-given PCR test turn around would be-- following reports now (ie. if the traveler gets their results showing negative in 3~5 hours, the 3 days in a Federal -appointed "quarantine hotel" would be zero days, and proceed to home under a 14-day quarantine). PCR tests given at US airports vary from ~$120 to ~$150 USD approximately. So, deducing, the cost for a Canadian airport PCR test could be in the ~~ $300 CAD range (to be confirmed). To be clear: I'm not promoting Canadian non-discretionary travel by air. I believe that all non-discretionary air travel World-wide should be halted immediately till a re-evaluation period in early summer. Partial geographical air flight bans don't work, and are a miserable failure; too many ways to "burn Rome" and get around measures

RE: New Border Regulations

....if anyone here from Canada is RVing and needs to get back by airline, you better do it quickly. The Canadian Feds just announced this morning that all flights in/out of "sun destinations" (this includes Mexico, the US the Caribbean, all of Latin America) are halted (read: cancelled) from now (today) till the last day of April. The only flights leaving (and returning) now are "repatriation" flights. Also, EVERYONE entering Canada: mandatory quarantine in a Federal Government-designated hotel for 3 days till their mandatory PCR (yes, PCR) results done at the 4 or 5 airport entry customs facilities are confirmed. The cost of these 3 days is $2000+ CAD and is to be borne solely by the returning traveler. After a neg. test, the traveler will undergo mandatory quarantine at home, under heavy surveillance. IF the PCR results come back "positive", the "person(s)" are to be delivered by the Feds to a special Federal Quarantine Facility, till they test negative. More later....

RE: 2019–20 CORONAVIRUS PANDEMIC POSTINGS

This article is dated January 15, 2021. Plans are underway to manufacture the vaccine in the northern Mexican state of Nuevo Leon. OK. There are two facets here: Russia selling their Sputnik vaccine doses....the other is manufacturing it. In my mind, unless that State has the manufacturing facilities already up and running (??), it will take a year of more to set up a vaccine manufacturing plant there. Standing by to see how many Sputnik vaccines are scheduled to be delivered.....and when.
