Horses, Powerful

What is a HP (Horse Power, not to be confused with Hewlett Packard). A non-standard unit for measuring power. What is power. Something that creates mechanical work or heat, in general occurs when one form of energy is transformed into another, in a certain amount of time. Transformed in watts, which is a standard unit for measuring power (metric this time, not to be confused with SAE, or Standard American and English which is non-metric, confused already? Wait a minute, HP is SAE?).

"Well i never knew" there was a Horse Power and then there was a metric Horse Power, i don't have time for this right now, what i know is a HP is approximately 7 hundred something watts and this is what i want to talk about.

There is little concern in the US for like how many HP a car has. Some people look for things like, room, confort, safety. All these result in big cars, vans or SUVs and big cars need many HP to move and many HP mean usually big engines, V6 being midd range. Other people look for prices and smaller cars with smaller engines that are cheaper. Just googled and i saw the average power for a car in the US is 120 HP. That can't be right, from what i see on the streets.

Anyways. An internal combustion engine runs at a maximum efficiency of... Nevermind, i ran into something else. Google gives the answer for that question 80% which can't be true. Don't know how google picks the answer, next answer in line is closer to what i knew, 35-40% for "advanced engines".

But in reality, for real cars and real engines, with an average age of cars running on streets of 12 years, the real thermal efficiency of the engines is 20%. Which means 80% of the energy of the fuel is wasted in the radiator and exhaust. Heating the Universe as some would say. So it's the exact opposite of the answer picked by google to that question.

And here's where i wanted to get. Due to air drag, friction of tires with the road, an average size car needs about 15 HP on average to cruise at constant speed during long trips. The rest of the HPs, all the way to 120 or 200 or something is for acceleration. Usually you use for a few seconds all the power of the engine until you get "up to speed" and then you release the gas pedal and start cruising. From what i see on the instant dashboard indicator of the Elandra, engine goes to a consumption of 14-17 mpg for acceleration and above 35 for cruising. Hyundai Elantra indeed  has one of those advanced engines.

However, it's got a wasteful automatic transmission with hydraulic torque converter which is way more efficient at higher RPMs used during acceleration and wastes a lot during cruise. Waste in automatic transmission is so great it needs a whole section of the radiator just to cool it, in the range of 5 to 15%.

The newer continuous variable transmissions used in newer models (CVT) are much more efficient.

To compare that 15 HPs needed to cruise to the beach to let's say the energy used by a house, we need to transform the HPs into watts. 15 HPs by 750 would be about what, 10 KW, or the average power needed for 10 homes, including heating, dryer, AC, hot water, stove, other appliances. But when thinking that we use those 15HP coming from an internal combustion engine that has a 30 or even 20% efficiency, we realize that during those hours we use the energy needed to power up to 50 homes.

So that's why i'm tweaking the Hyundai almost every day, giving "them" opportunities to come outside and to their shows around me. Today it was raining and got wet and cold about 3 times (and they still started to move around me).

Because i saw one day i made from here to Spirit Mountain, a 49 miles trip, on other occasions, a mileage on the dashboard indicator of 39 mpg. But that was one day only. About half the times i get 37. It's not that much about the money, though a 15% difference in fuel consumption with that car would be about 1000 a year. It's curiosity and also pride. Hope i can prove something.

Then, every time something breaks allowing a vacuum leak. Last night coming back home it was 34. I replaced until now the hoses around the catch can i don't know how many times. Last time today, i found under one of the clamps a... hairline crack in the rubber hose? that was so straight it seemed a cut. I used high pressure, oil resistant breaded fuel lines. So i replaced them with PVC hoses. I modified the clamps, cause they were "gathering" the tire in one point or line and where not perfectly round.

I don't know why it's so important, but by freshly tightening those hoses, i get 15% better mileage. For that trip only. When i check the next day, i see they're loose again. The rubber gives in and then cracks. On the PCV ones, it looks like they get untightened. So i added extra nuts on the bolts.

The vacuum inside the intake while crusins is what, 15psi, but the problem is that is an average and it probably pulsates peaking at around 20 or something and probably the opening of the valves and sucking of the pistons gives shock waves through the hoses that combined with the movement (vibration) of the engine creates temporary pulsating leaks.

Original PCV hose (used without catch can) is preformed rubber, with spring clamps that barely tighten. I know Hyundai redesigned an engine with the shaft a bit off from under the pistons to make the angle at active stroke smaller just to get an increase of 1% efficiency when they are probably loosing for older or even newers cars up to 10% or more because of a hose and clamps.

I remember 15 years ago with the Nissan used mostly by Angela to go to work and for trips in weekends, i found a puncture in the heater hose, and i kept pouring coolant and coolant kept disappearing until i found that leak and went and fixed it. To me it looked a puncture made with a tool.

I don't know what to believe anymore.

Cyber Threats. Real or Myth

My opinion. They are as real as everything else. Governments, politicians.

In an ideal world (not the one we live in obviously), we should expect no critical infrastructure communication network is physically connected to the internet. I personally don't believe they are. They shouldn't. Classical example, power grid. What else. The controlling part of the phone providers. The military. Etc..

They should and probably have their own separate physical networks. It would be insane if they didn't.

Many people can't make the distinction between the front sites of the institutions giving access to a tiny fraction of the information from those sectors and their internal networks. There may be connections but one way only. Read only, if  you want. By hardware design.

By example. One should be able to go and check online his account with the power company. But that is the accounting part of it. And only the read only of the accounting part of it that details power usage and whatever, price, cost. The rest of it as the IT infrastructure controlling the grid should be physically isolated from the internet and probably is. Same with banks, government agencies, etc..

From time to time they come and bring us this unverifiable "news". Things that happened in the past and "they didn't know". Those that if you search the source of, you would find to be the source of all confusions and misunderstandings we leave with nowadays. When they squeeze everything they can out of those that never verify in the end they switch to some other imaginary threat.

About the recent "Russian" cyberattacks. The main problem here is the Russians don't deny it or don't make the slightest effort to educate the public in "the other countries" they are supposedly menacing. I bet vast majority of Russians don't even know about. They have a totally different view of the world, with their own journalists and their own news, tailored to their needs. And the language and especially the alphabet barriers. Most Russians can't read latin alphabet so they can at least read the titles from the sites.

They a front news agency called Sput Nick that sometimes is as confusing as American main media. Who wants to read Sput Nick or Spit Nick? It is made mostly for their own English readers so they can believe they are not totally isolated. Because they are in the same situations. Fake politicians, fake governments controlling everything.

Why they need this constant tension? Simply to take peoples' mind out of the real problems.

"On the other side are experts who say such warnings are vast exaggerations peddling FUD (fear, uncertainty and doubt) – that natural disasters and rodents are more of a threat than cyber attacks to industrial control systems (ICS) that power the grid, water distribution, transportation and other critical services.

The evidence – so far – seems to favor the latter view. No cyber attack in the US has crippled the grid, water, communication or other CI systems even for weeks. Indeed, major storms have left tens of thousands of people without power for longer than any cyber attack has."

Rodents. They (CSO) compare cyber threats to rodents. Rats that is.

One more thing. Who ever needed internet as an open, international network? What are 99% of Americans 99% of the time searching in other countries web sites? Nothing.

Uku Lelea și semaforul.

Ok m-am hotărât să nu mai scriu ce mi s-a întâmplat în parc înainte și după, devine plictisitor și pentru mine și pentru cei care citesc dar am venit acasă și am pus iar un video și m-a lovit iar nevoia de a scrie.

Deci. M-am dus să-mi iau frumusețea de camionetă din 98 din parcarea de lângă stradă, la 5-10 minute de mers de aici. Resetasem ieri computerul (poți să-l resetezi prin deconectarea bateriei, ștergerea codurilor de eroare cu ajutorul unui conector blue tooth de vreo 3 dolari și o aplicație gratuită, Torque Lite (pe care am plătit-o odată, dar am resetat tableta și nu mai merge), cu care poți citi și senzorii, etc.). Am vrut să-l resetez azi din nou dar am uitat și l-am pornit.

Ce se întâmplă. De câte ori resetezi computerul la mașinile mai noi de 96, motorul iese din funcționarea pe buclă închisă (closed loop, optimizat) și intră într-un mod generic (open loop) și începe să facă niște teste de senzori perioadă în care nu scoate coduri de eroare. Dacă trec toate testele, intră pe closed loop și începe învățarea stilului de conducere pentru a optimiza consumul și emisiile.

Rezistența de încălzire de la al doilea senzor de oxigen (ăla de după catalizator, cu 5 fire). Se rezolvă cu o pornire la rece (temperatura lichidului de răcire să fie cam aceeași cu cea a aerului și mai mare de 4 grade Celsius, deci după o noapte, dar se prea poate iarna. Adică se poate dacă prinzi o dimineață peste 4 grade sau 40 Farenheit). Al meu l-am schimbat aiurea acum doi ani fiindcă nu știam chestia. Dacă trece, face și testul senzorului însuși în vreo câteva minute de mers sub 40 la oră combinat cu ralanti. Apoi supapa de recirculare eșapament EGR (pentru răcirea amestecului, se recirculeaza o mică parte din gaze de eșapament în galeria de emisie, care micșorează temperatura și practic crește cifra octanică printr-o supapă comandată de computer, a nu se confunda cu supapa de recirculare pentru aerisire, PCV). Și aceea era schimbată, dar a fost într-adevăr defectă. Pentru aia trebuie să mergi vreo 5 minute peste 90 la oră cu viteză constantă. Deci trecusem toate testele și m-am dus la stația de testare care era închisă. Luni, uitasem.

Am emoții fiindcă dacă nu trece, trebuie să schimb iar catalizatorul pe care l-am schimbat deja de 3 ori, fiindcă tot așa nu am știut chestia și am pus catalizatoare ieftine, care nu au cantitatea de ceramică necesară și se duc după vreun an (un catalizator bun nu are cum să fie sub vreo 500 de dolari și de obicei trebuie să iei unul original). Dar cum s-a stricat și ăla. Într-un an pe 3 iulie (2010) am mers undeva și când am venit acasă pe drum mașina a început să facă un zgomot foarte nașpa, ca de pietre care se rostogolesc, de fapt se spărsese blocul de ceramică din catalizator, care e o chestie rară. Chevrolet S10 este un tip de Chevrolet făcut de GM în colaborare cu Isuzu care au și ei unul identic care se numește Isuzu Hombre.

M-am întors și am intrat puțin în parc. Adică pe strada de pe lângă, cum merg eu mai recent, din cauza prafului de piatră de pe alei unde au turnat pietriș care se macină și se face praf foarte nașpa. Am mers eu vreo 10 minute și am dat de un nor de fum. Foarte subtil, fin, cum zice Angela. Cel mai probabil cocaină, care seamănă mult cu fumul de vegetație. De fapt, e tot o plantă și aia. Mă gândeam iar, cum m-am mai gândit, dacă nu cumva Gingis Han nu a folosit asta ca pe o tactică de luptă. Adică iei niște provizii de ceva plante de care lumea în Europa nu a auzit și niște meseriași care știu cum bate vântul, trimiți doi din ăia care fac unul două focuri din direcția vântului lângă tabăra sau satul pe care vrei să-l iei. Oamenii din tabără sau sat simt puțin miros de fum, dar nu știu ce e și într-o oră două devin happy, încep să facă tot felul de chestii, după care vii și-i iei cu pierderi minime. Astfel a luat el Asia și o parte din Europă, pe care însă nu a putut s-o țină, fiindcă habar nu avea de cultura și mai ales religia locală.

Nu mult fum, dar m-am întors. Eram puțin happy dar nu prea. La ieșirea din parcare prima fază. Se bagă o tipă în față (aici sunt foarte puțin pietoni) să treacă pe trecere.

Dar în intersecția următoare și singura până acasă, la 7-11. Se face verde, pornesc încet și semnalizez stânga, vine un tip din parcarea din față de la 7-11 spre mine, îl las să treacă înaintea lui pe lângă mine (aveam semn să cedez dacă fac la stânga), mai iese unul și face la dreapta, îl las să treacă și pe acela, fac stânga și în ultimele secunde de verde apare și un pieton întârziat care trece strada de la stânga, pe care nu-l văzusem din cauza celorlalte două faze, la care frânez. Un tip roșcat cu barbă destul de lungă. Vin acasă, încerc să mă relaxez, pun un video, îl văd pe tip, singura diferență e că avea barba mai lungă decât în video. Și apropo e prima dată când mi-am dat seama că tipul are barbă roșie fază la care îmi vin în minte versurile "woke up to a red parade and refused to make amends".

5G

In a feat of reverse psychology, 5G scare started with rumors about China taking control over areas involving personal privacy and security of the US. It ended with the arrest of a woman in Canada and banning of Huawei technology from many countries including the US (BTW, what Uighurs have to do with Huawei's 5G?).

Mostly concerned with my own physical safety over privacy and other issues, i started to search and write on the subject. But before that i have to put down with some stipulations. In my opinion, formed after many years of being in the middle of a story that clearly involves agents of the Empire of Japan controlling many aspects of my life, i came to the conclusion that China has been fully taken over secretly by Japan, many years ago, under the camouflage of a communist dictatorship and nowadays is used as forced labor base for massive exports of electronics products in the US with the purpose of de-technologizing, de-educating, downgrading, and generally annihilating the work force and ultimately entire population of the US. If tomorrow China would stop exporting electronic goods to the US, US will be paralyzed because they don't have the capacity and readiness to take over this production that has already passed several levels ahead of anything produced in the US in the past, with the exception of Intel maybe.

After stumbling yesterday upon the existing standards for protection from levels of emissions of the "older" technology (1.6 watts/kg), that were probably adopted just to fit the technology and products, not to protect anything, without any scientific backing or studies, they are "just" starting to study the long term effects of "low level" microwave exposure, low meaning it does not instantly boil you, most of the studies searchable on the internet are dated after the "adoption" of the standards, which also proves many other people have second thoughts, and contemplating the enormity of the "allowance", of which many probably don't understand, what else can be said?

One typical, way too circulated American phrase: If you think that is bad, wait until 5G comes. (If you don't, do the same. It doesn't matter).

The main novelty brought by 5G is the way signal is transmitted to the tower (and back but that is not that interesting because of dispersion and distance). Ironically, with the purpose to save power, the emission is made directional and confined to a narrow beam which then can be much stronger (denser).

How narrow, about the size of the antenna itself. This way, the power density can be increased to levels allowing much higher speeds (for higher speeds you need more power to beat the noise which becomes important at higher frequencies modulation). Yes, you read right. With the same 3 watts or whatever, (power is limited due to probably using the same batteries), you emit a narrow beam instead of a spherical wave.

This way you eliminate waste of energy (most of the signal up to 4G goes to nowhere usable) the intensity of the signal can be hundreds of times higher using the same power.

At first it seems ok, if it's directional and does not go all around, it would go to the tower and not to your head. Maybe.

That's what i thought myself for a few seconds or so. But then, you hold your phone in your hand, right, the beam would go right through it? From what i read so far, the beam would follow the tower even if you moved around, actually it wouldn't make sense if it wouldn't, and phased array is the technology used in radars that can scan the area in front of the antenna many times a second, and the phone's inertial and gravimetric sensors together with GPS know its own position so it's perfectly doable, actually already done (though looking weird to me). So what happens when you turn around while pacing and speaking into your office and the tower moves on the other side of your head? Let's say they were conscious enough to embed in the design a function that would allow switching to another tower that is again facing the back side of your phone. But that other tower would be on the other side of the building, right, and the beam won't go through.

I wouldn't dare to say what others did, what would happen when you have a conference meeting with each member having his own beam following each its own tower (carrier)?

Here the technical details i've been trying to delay. How a phased array antenna inside your phone looks like and especially where it's located. (3 in this image).

How are they going to comply with the already immense limits, if the power would be the same 3 watts max but the beam would concentrate all that power in a few square inches?

And ultimately, why do we need all that, just to watch 4k movies on our phones when going in the park?

Here's a really smart one. (It's tough indeed to get radio signals going through metal, duh!)

"no one had demonstrated that it’s possible to build these antennas into phones with full metallic casings, as can be found in the high-end mobile devices from numerous manufacturers [didn't know numerous manufacturers have already manufactured numerous high and/or low end 5G mobile de-vices]. Now researchers from the Shanghai Institute for Advanced Communication and Data Science at Shanghai University in China have developed a 28 Gigahertz (GHz) beam-steering antenna array that can be integrated into the metallic casing of 5G mobile phones."

The trick is, the signal doesn't really go "through" the metal casing, it takes a detour through the glass first. Then it reflects and/or difracts on your head and provided the system is smart enough, will focus onto the tower and adjust strength, by trial and error, taking into account (or maybe not) your head's conductivity.  If  you don't believe me, take one of these, find where the tower is and keep it away from  your head and tower and tell me if you have any signal (nevermind, would probably still have diffraction on the edge of the case and some signal, maybe 25% would go through). Which brings me, this time to a rhetoric question, how the signal goes through "the metal casing" of the "high end" phones for the classic, 4G ones? (unless if the casing itself is the antenna). Nevermind, curiosity got the best of me. And after reading that, here's a good idea for the "high end" users. Better hold your phone with the metal case to your ear!

Android and Masseter Muscle

Android phones are totally unreliable. With dozens or hundreds of apps running in the background, most of the times having some you don't even don't know about, most likely of unknown origin, they can do weird things. One of the symptoms sometimes may be fast discharge of the battery. But where do some of that lost power go?

Today i started to re-consider the idea that the problem behind my inflammation of the parotid glands but also... masseter muscle or even prostate, sciatic nerves, may be the phone.

I got a phone from Boost Mobile, for 80 bucks, but i only used it with Boost a couple of months and now i'm using it on wi-fi only (when available). I always assumed wi-fi, which uses the same frequencies as cell phones, cordless and microwave ovens, would use less power, because of limited distance.

After months or maybe years of inflammation in that area (including tip of the ears painful, like after being outside in cold, other symptoms, like loss of balance) it occured to me several times it could be the phone but i forgot every time.

I once had a microwave leak detector identical with the one in the picture below. I took it apart and i saw inside there was only a GHz range diode and a magnetoelectric type of meter. If i kept it inches away in front of the microwave, the needle would move and if very close, the needle would go on red. But the leaks are way bigger if there is nothing to heat up in the microwave, like if you start it empty though that never happens in practice. In this case needle would go over the range even inches away and still move at one meter distance.

I broke that leak detector and threw it away and years after i wanted one and could not find it anymore and i bought instead a diode like the one inside the old one for 2 bucks somewhere, maybe at Fry's and used an old analog meter, which i stripped of electronics and i put the diode and a piece of wire figuring a dipole in series with the meter and it shows similar readings near the microwave (shown in the videos at the end).

When i tried that one close to the phone i saw the needle would move in similar ways with the first one when close to the microwave oven. It makes sense since microwave ovens work at 2.4 GHz, close to cell phone frequency (i think 5G doubles that).

I tried the same with Angela's and it doesn't move the needle though she pays for voice and data and mine works only on wi-fi. I tried it near the wi-fi router and the needle moves as well over there.

A new 700 watts 2.4 Ghz microwave oven may leak 1% of the whole power and that is also the maximum amount the phone can put out when talking to a distant tower. 99% of the time when used in town the phone uses only a fraction of that power, it goes to maximum only occasionally.

Question is if 0.6 watts maximum power is a hardware limitation or some manufacturers put bigger emitters inside the phone just in case, that are only software limited. What if a foreign app gets inside your phone and start turning that emitter at maximum power every time you put the phone to your ears?

Cordless phones use similar or lower frequencies and slightly less power. But who can guarantee the manufacturers, trying to "improve" the quality of the signal, won't use more?

Microwave leaks at ovens happens only close to them where you don't usually stand with your head and will decrease to 0 at one meter distance if you have something to heat in the oven.

Is it acceptable to have about the same level from a phone that stays close to your skin and other organs? Is 1-2% of the full power of a microwave oven for one hour a day too much for your head? I believe anything above 0 is too much already.

Before the Moto e6 i own now and other previous Android phones we had a couple of small blackberry imitation phones with cameras that weren't smart phones. I was also talking a lot on cordless maybe hours a day during those days. I gave up cordless phones in 2015 when i stopped using a landline.

It was around that time when i started to have symptoms like loss of balance, which were most likely caused by increased intracranial pressure due to infections in the area close to where you hold your phone, that were propagating to the meninges and spine. One prolonged course of antibiotics of several months and discovery of diabetes in 2015. I think diabetes occurs when infection from salivary glands inflamed from your phones (cell and cordless) propagates to the pancreas that has some similarities with parotid glands (at least a few similar cell types for production of amylase).

Nowadays, besides the bulges on both sides in the area with masseter muscle and parotid glands, i lost much of the facial hair in that area (sideburns), have pain at the ears, dizziness, weird punctual headaches, after eating or in the morning, etc..

All i have to do now is not put that phone to the ears or near my body when it's on and wait and see.

One more thing. I think i exposed myself to a good dose (since i'm sensitive already) when i filmed this video because if you start the mwave with nothing in it it will leak much more.

I had no idea until one minute ago that they have "regulated" levels of leaks for microwave ovens which proves that my concern is real. Google even mentions the levels considered safe. At first glance they look insignificant. 5 mW per square centimeter. FDA, an American agency, this time gives it per square centimeter. Because per square inch that value would be... about 6.4 times greater, at 32 mW per square inch and wouldn't look so small anymore. This confirms all that i was saying. 10 square inches or about 3x3 would be about the size of a human organ maybe like a fist or heart and that would catch about 320 mW of power if close enough to the door.

But if i multiply that amount, 5 mW with the whole surface surrounding the oven, which is about 1/2 of a square meter or 5000 square centimeters i get... 0.005*5000 = 25 watts! (If modulated, it would reach a tower or cell phone at what distance, more than 100 miles maybe?).

Going back to cell phones, that move my needle in the same way, that amount would be 1 watt per whole head. But there are still too many unknowns. Microwave leaks from that oven that i use as reference to measure the emissions of a phone could be under the recommended limit. But i know for sure that when i bought that monitor many years ago i had an old microwave that was interfering with my satellite dish that was ft away and the levels shown with the monitor where not much greater than the ones i see now.

From what i've seen lately at politics and politicians, i don't expect anymore any kind of protection from the part of environmental agencies from hungry or dishonest or even maybe misintended sellers (or maybe the opposite) and it does not surprise me at all that we are exposed to harmful amounts of microwaves from cell and cordless phones and ultimately from ovens. There was this idea circulating in the media some time ago about getting cancer from cell phone radiation. I dismissed it because i misinterpreted what i was seeing when i bought that detector (monitor, whatever, the first picture), because emissions from cell phones seemed in the same range with leaks from microwave ovens and my monitor was in the green a few inches away from both; however, again, you don't hold an oven next to your head.

It's not cancer that you get right away but a whole list of other serious illnesses of which some me and my acquaintances are experiencing right now (of which i didn't mention thyroid problems) in people coming from generations of healthy ancestors but living in much better conditions (life quality has improved dramatically in the last 50 years or so). The fruit of my ignorance combined with trustfulness, and plain criminal, genocidal, malevolence of some.
