There is no point in coming up with a theory like GWD if you can't do the math and make some testable predictions as to it's accuracy. There is a big difference in the way that general relativity was taught 30 years ago and the corrupted version that has been taught these last 20 years. You can see it in the original version of the book "The New Physics" compared to later volumes. Fraud of the century. Key quote from NASA article Quote But string theory is highly controversial, in part because most of its predictions are virtually impossible to verify with experiments. If it's not testable, it's not science. For decades I've been complaining about the un-falsifiable religion called AGW. No one has devised a legitimate test, although hundreds of billions have been spent. Simulations are cute and all, but completely meaningless. When they are running thousands upon thousands of simulations every year and one of those gives a pseudo accurate prediction, they trumpet it from the rooftops. They are extremely silent about the tens of thousands that were flat out wrong however. If real physicists were involved with climate science instead of these charlatans, I believe a real experiment could be devised and executed. Of course the political powers that be won't fund such an effort because they already know what it will prove. CO2 simply does not "force" water vapor the way they've been claiming.

They don't need to be 60 KW chargers. Assuming a 120v supply I would have thought a 20-30 amp outlet would suffice for this type of charging. No need for a link to the apartments consumer unit. Plenty of firms already developing such services. https://pod-point.com/solutions/driver/apartment-charging 120V is capped at 20Amps and 12 gauge wiring, by NEC, but most apartments do not have 20Amp wiring, but rather cheaper 15Amp 14 gauge wiring which limits them to a maximum of 120V(its actually lower)*15A*80% = ~1.2KW continuous. Kitchen outlets are always 20Amp. In fact, most new housing in the USA have 15amp breakered outlets. Not only cheaper but safer for shocks/fires. All +30Amp wiring is 240V or 208V if source is 3phase in the USA. So, if limited to 1.2KW, then average car is going to have to charge for ~10hours. Yes, crude approximation. Garage outlets are typically 20Amp 120V and often you will find a "welder" general purpose 240V 30Amp outlet in a garage. Why all the chargers sold in USA use the 120V@20A or 30A@240V outlets in the USA and generally speaking if one wants an outside charger, this requires an electrician and putting new hardware in from service panel. EDIT: Woopsies, 15Amp is rated at 70% continuous and 80% peak. Why appliances all go under 1.2kW sold in the USA. Unless specifically for kitchen use and then will be 1.5kW Edited October 7, 2020 by footeab@yahoo.com 1 Quote Share this post Link to post Share on other sites

The interview runs about 90 minutes Very interesting, always great to hear the personal views of a giant like Penrose. This may help you understand what he is saying in a little more detail: https://www.britannica.com/science/cosmology-astronomy/The-Einstein-de-Sitter-universe And this is the kind of thing that puts a spanner in the works for even the greatest of the great minds: https://www.reuters.com/article/us-space-exploration-darkmatter-idUSKBN26231N?taid=5f5c3f8d9ce301000129bc01&utm_campaign=trueAnthem:+Trending+Content&utm_medium=trueAnthem&utm_source=twitter My personal favourite is this: https://www.bing.com/search?q=graviton&cvid=53115729589e40d793d24b2b2c56ccfe&pglt=43&FORM=ANNTA1&PC=U531 supported by this: https://www.newscientist.com/article/dn1801-gravitys-quantum-leaps-detected/ However, I do not believe in string theory and agree with Penrose that there is something fundamentally wrong with Quantum Mechanics because it does not make common sense. Given that it requires vast amounts of energy to find the smallest particles, I believe the early universe, which involved temperatures and pressures that not even CERN can get anywhere close to, probably contained particles much smaller than the standard model predicts. ie: gravitons and anti-gravitons, an imbalance of which represent dark matter and dark energy. I am not that good at maths to be able to put together an article like the one above on cosmology, but the fact that they still can't marry Quantum Gravity with Relativity and have no idea what Dark Matter or Dark Energy actually is, suggests to me that Einstein's equivalence principle will continue to stand the test of time. The word Atom means "indivisible", and was long thought to be just that. Then along came Rutherford, who showed it had a tiny nucleus, and then the nucleus was found to consist of even smaller particles (neutrons and protons), then we got down to leptons and baryons.... Making the assumption that the Standard Model is complete and that we have any idea what the conditions of the universe were like in that tiny, hot ball at 10 to the -43 seconds is foolish if you ask me. Indeed, I don't even believe in the singularity. Or infinity for that matter. What the hell are nothing or forever? Penrose does a great job of explaining what they mean mathematically, but I don't think us humans will ever be able to understand the true mysteries of existence and time, no matter how much information we have. As you can see, discovering the "God Particle" has not helped one iota in our understanding of cosmology yet 1 1 Quote Share this post Link to post Share on other sites

Ah, you will now regulate(DEMAND) that all chargers magically measure current of entire system before turning on/off... Those hall effect sensors do not measure power factor... Oh this is genius... which means they have no idea if they can run or not. Only gives a ballpark. Which means now we have to monitor incoming and outgoing voltage for your demand to work... Why? Chargers destroy the power factor which makes the power company VERY unhappy(big businesses get charged extra based on power factor and now you want whole cities/neighborhoods charging at night). This now means that the charger in question must be a VERY expensive high frequency chopper inverter instead of the dirt cheap variety which is used on everything. Why? 1) Voltage differential and 2) wave forms are overlapping which has massive frequency implications on equipment. Very expensive equipment. Great, your causal "demand" just blew up the cost on the charger to insane amounts so instead of upgrading panel, you now have to massively upgrade the charger cost and have a VERY expensive installation which also requires modifying your panel anyways... And has no future benefit as the panel is still too small and will need replaced next time some idiot new electrical code regulation is shoved down everyones throats irregardless of cost. EDIT: Yes, I will be VERY sarcastic to those with ZERO knowledge of engineering who casually "wave their hands" at problems and DEMAND results all the while sitting there all smug as if they said something brilliant... then get pissy when someone trounces their stupid shortsighted ignorant idea.

I see you are now switching the debate from the capacity of the building to import power and the ability of the grid to supply power. These are two separate areas. In terms of the building. Lets take this down to a single domestic property (you can scale up to suit large apartment blocks). In coming supply 240v / 80 amp. The charger simply monitors the incoming power and limits the total demand to say 75 amps and adjusts the charger accordingly to not exceed this. In the UK we already have this type technology routinely available for people who want to use their own solar panels to charge their cars. The charger controller automatically adjusts the charge rate amperage to reflect the surplus amount of solar available. As regards demand on the grid - well thats already resolved as anyone who can will routinely charge off peak utilising underused CCGT plant. In the UK for example, overnight we have about 15-20GW of CCGT idling. However if concerned about overloading the grid then chargers can easily be fitted with dynamic demand response switches which basically switch off the charger if the grid frequency falls below say 49.75 Hz. However I dare say none of this could ever be done in America if you are to be believed. https://gridwatch.co.uk/frequency Quote Share this post Link to post Share on other sites

The whole reason I did Physics was to try and get a deeper understanding of the Universe but didn't think we would get there. 30 years later, I am blown away at the progress that has been made. Still so many questions, but at least now we are narrowing down the possibilities. After Physics, I did Environmental Science (more like an agriculture degree), and Business, but due to ill health, was never able to pursue a career so have stuck to providing free advice to govt of all levels on a variety of matters. Now, I will be eagerly awaiting the results of CERN that should be available by 2030. What a time to be alive!

Works well if you have the available micronutrients (as do greenhouse operators) . However in the open environment once the ground is exhausted the Co2 will not increase growth rates because the micronutrients have now becoming the limiting factor. 1 Quote Share this post Link to post Share on other sites
