It totally does not matter what the total insolation is. It matters. It is what's available. It matters what hardware we can build to capture it. Yes, that also matters. And store it to make it useful, Which will never be anywhere near 1/3 of what we are using today. Any time anyone looks at a nasc...
The only thing you have proven is that you are prepared to ignor manufacturers service requirements. We could all just ignore the manufacturers recommendations, void the warranty, risk the failures, etc etc.. but the FACT is EV have service requirements much the same as any other car Again, no. I'v...
Since you are so sure there is an impending societal collapse (or at least upheaval), I'm curious what action you are taking now to protect yourself? I suspect the answer is "none" because even you don't really think it's going to happen in 10 years. Personally I think it will - but it will happen ...
So many wrong figures !!.. Indeed! Let's list them. your coal plant runs low CF ..why ?. Maintenance, uneven power demand, cheaper power available during the day, things like that. and i would expect a new plant to be better..hence the 2.0 GW capacity needed for 15TWh annual. OK. And new solar and ...
Only a fool would ignor the warranty conditions on a new car..especially one that could require a $10k + battery replacement. Let alone the numerous safety checks. Based on the acumen you've shown here, I will take that as a compliment! The point is ...the MYTH that EVs do not require expensive ser...
...and from the Leaf service manual (which you apparently didnt bother reading during those 7 years . . . I read it; I just didn't want to waste money on that stuff. (And I never needed it.) I bet car dealerships love you! You bring your car in every 7500 miles to the dealer for an oil change, a ca...
How many sqr kms of solar farm, or how many wind turbines, do you need to produce the same power as one coal plant ? Easy. Plant Scherer is a large coal plant in the US. 3.5 gigawatts, capacity factor 61% - so 2.1 gigawatts average output. 3500 acres for the plant. It uses 11 million tons of coal a...
It varies depends where you live, Gov rebates , tax concessions etc etc. Absolutely. (True for all kinds of cars.) i hope you mean zero cost, not zero maintenance ? Most maintenance on modern cars is just inspection ( labour cost).. you might avoid the cost ( free service deals, etc) , but you cann...
Not exactly a myth but a misconception: All bateries need to be kept full all the time and will develop a memory if you dont keep them topped off. That's an odd one. I think it surfaced during the time that nicads were used often, and they had a problem with lower than normal discharge voltages - i...
Accellerated installations beyond previous achievements ..how ? By hiring more people (= more employment) building more factories to produce turbines, PV and batteries, and installing more grid infrastructure. Solar investment has practically dried up since the rebate schemes were cut, and wind is ...
Here are a few.. * EVs are economical to own and run Lots of people here got on board with the recent Volt deal - $214 a month, $611 cashback. Ended up being $191 a month over the term of the lease. * EVs are cheap to service. Yes, they are. Zero maintenance on the Leaf I had for seven years. Zero....
City buses are another sector that will be very quickly electrified once the battery cost tipping point is breached. With fairly minimal incentives this is already happening in China with whole cities now entirely electrified. Margins on bus routes are slim, any decrease in vehicle running costs ca...
The point is, don't trust racers when they tell you what works. They are contractually obligated to be shills whether they like it or not. Yep. But the racers that win, in general, have the combination of equipment/training/attitude/perseverance that works. And those people, more and more often, ar...
You understand how sponsorship works, right? People pay you money to use their stuff if you win a lot of races. Of course, first you have to win a lot of races. Which is why so many TdF racers are switching to discs. Some reasons, from Bicycling Magazine: Winning. Stage winners for the TdF are star...
Greg Herbold, John Tomac, and the other competitors in the then-new sport of MTB downhill racing at the turn of the '90s seemed to do fine with rim brakes. Disc brakes were available to them if they wanted. Shimano's came out in 1975. And now every single competitor uses discs. Every. Single. One. ...
This sounds like it might be the direction to go. Unfortunately electronics are well beyond my pay grade...but I can follow directions pretty well. I'm running QS Motors hub wheels with KTY83-122 sensors (1000-1020 ohm, Positive Temperature Coefficient). What size semiconductor resistors would I us...
Now I am not a lawyer, either, but . . . What works as a waiver of liability varies by a lot, from state to state. Make any mistake there, and all you will have is a sheet of paper. That's a bit of a misconception. You don't need a secret formula to write up and sign an agreement. The standard is "...
Disc brakes existed for several decades on motorcycles before making their way to bicycles, if rim brakes were so deficient I think this would have happened much sooner. They're not so deficient, and are plenty to stop most bikes. But keep in mind that ebikes are now approaching motorcycle speeds, ...
