Funny how after years and years of Climate Change and Global Warming the deniers have now adopted the platform of non-denial to one of Climate Change will be a good thing.
 
The latest report from the World Meteorological Organization show how record greenhouse gas levels are driving temperatures to increasingly dangerous levels.


“Key findings of this Statement include the striking consecutive record warming recorded from 2015 through 2018, the continuous upward trend in the atmospheric
concentration of the major greenhouse gases, the increasing rate of sea-level rise and the loss of sea ice in both northern and southern polar regions.

The understanding of the linkage between the observed climate variability and change and associated impact on societies has also progressed, thanks to the excellent collaboration of sister agencies within the United Nations system. This current publication includes some of these linkages that have been recorded in recent years, in particular from 2015 to 2018, a period that experienced a strong influence of the El Niño and La Niña phenomena in addition to the long-term climate changes.

Global temperature has risen to close to 1 °C above the pre-industrial period. The time remaining to achieve commitments under the Paris agreement is quickly running out”

The world really needs to find alternatives for transportation. I'm hoping that Graphene batteries are the answer. Ironically, they are made of carbon!

It would be nice if the prices go down. Right now, they are probably 20 times the cost of lithium ion.

Research phase. You can't buy them. You can buy LiIon batteries with a graphene coating on the anode and cathode to speed up charging.

No, they are available. They were around 10 times what I paid for some lithium ion batteries a couple years back, so I guessed with Li-ion prices lower, about 20x today.

You have many positive examples from around. For example that a third of car sold in Norway during 2018 was zero emissions adding plugin hybrids the percent was 49 percent.

Electric car sales grew by 40% in Norway this year - Electrek

In Sweden you have intersting road trials with electrified roads.

World's first electrified public road opens in Sweden - The Local

While in China you have trains that runs on virtual tracks without rails and cables for city transport.

That you even have plans for electric powered aircrafts.

While long distance air flights may need to be solved through a combanition of reduction in flighing, biofuels and hydro and also new innovative technologies.

I will bet that they have some kind of incentive and smart systems that charge the cars when they have excess wind, that would be wasted otherwise.

Electric cars can be programmed to start and stop charging based on time. If one is charging with a 220-Volt system, he can start the charging late at night, when Utilities are experiencing their lightest loads. I believe electric auto manufacturers will start recommending late night charging. They could mandate it with the software....

There are also potential to charge the car then the demand is low and sell back to the grid then the demand is high. Thereby saving monet for the car owner as well help to balance the grid.

You can now power your electric car from the sun. Solar-Edge has this system, and you can use it with or without Netmetering --->

Most people don't consider a 300-mile range, with a 20-minute recharge less mobility. Electric car drivers love accelerating from ZERO to SPEED LIMIT in seconds. Now that's "Freedom of Movement"!!!

Number 35 was a post about other aspects of electric vehicle. For example, it takes me about 5 seconds to plug in my car when I get home. Meanwhile, you have to fight traffic to get to a pump and wait in line at the pump. You have to wait for credit card approval. You have to smell the fumes of all the vehicles pulling in and out of the gas station. And all that, so you can then be gouged by the oil companies, and use their polluting product.

Are you making that up, or do you have data to back you up?

Isn't a 300 mile range something like 50 kWh or power or more? In 20 minutes, you would have to charge at a rate of 150 K watts...

The Tesla S has a 237 mile range with the 75 kWh battery, and takes over 72 hours to charge on 110 volts. One hour at 440 volts. With the larger battery pack, it has a range of 285 miles and takes over 96 hours at 110 volts and 1:20 on 440v.

Just how small of a car can have a 300 mile range and only take 20 minutes to charge for that range?

You sure like making things up...

I'm not doing your homework for you again. I've been reading up. Look it up, and provide a link, and I will respond.

Yes, but that is with current power types and typical usage. If solar becomes a primary means of power, the daytime will be where the excess power is and the ideal time to charge cars. If wind is a primary power source, cars plugged in to recharge can be on a smart system as to control when they are allowed to charge. This would help balance out power needs and reduce storage requirements.

Sorry, what you said sounds like 100% BS.

I simply don't buy the 300 miles in 20 minutes, and you claim to be an electrical engineer...

Again, that sound like 100% BS too.

Seriously? A charge rate of 30 thousand watts for every 10 kWh capacity needed... Think about that for a moment... The voltages needed at what current? Can't approach 600 volts, because then OSHA has serious rule changes at 600 volts. The size of wire gauge needed for your charge time...

At 440 volts, 68.2 amps for every 10 kWh battery capacity needed...

We aren't ignorant like most your lefty buddies. Most of us who disagree with you understand simple science.
 
There are also considerable safety rule changes when using a transformer over a certain power capacity. I believe it's 150 kW, but I'm not sure if that's the number.

You can't blink with the advances in charging technology.

Really fast electric-car charging stations coming to a Walmart near you

Electrify America says that the Walmart installations will include DC fast chargers with up to 350-kw of power that can replenish 20 miles of range per minute—plenty to fill up your 200-mile electric car while you shop.
