The climate change consensus extends beyond climate scientists

Yeah, seriously.
Sweden has already electrified 2 km of public road: https://reneweconomy.com.au/worlds-f...-sweden-97633/

... at a cost of €1 million per kilometre, the cost of rolling out the technology to more of Sweden’s roads and highways, and to the EV-driving public, is estimated to be 50 times lower than that required to construct an urban tram line.

The grid comes with its own set of risks...

A dozen wildfires that burned thousands of homes in California's wine country and killed at least 15 people last October were started by Pacific Gas & Electric power lines and utility poles, state fire officials said.

Climate change is not an existential threat. Show me someone with compelling data to suggest it is and I'll be open to the idea. I've not heard anyone but environmental extremists suggest humanity is seriously threatened by GW.

I agree that freedom is conditional, which is why I'm not a Libertarian. Their attitude often is something along the lines of "what do you care if I pee on my end of the pool".

The thing is, when everyone is peeing, it takes a united effort (global) to have a meaningful impact in a just way to every person.



From your link:

Disadvantages
Slower charging – Due to the lower efficiency, devices take longer to charge when supplied power is the same amount.
More expensive – Inductive charging also requires drive electronics and coils in both device and charger, increasing the complexity and cost of manufacturing.
Inefficiency – Inductive charging is not as efficient as direct charging. In one application, the phone being charged gets hot. Continued exposure to heat can result in battery damage...the Magne Charge vehicle recharger system employs high-frequency induction to deliver high power at an efficiency of 86% (6.6 kW power delivery from a 7.68 kW power draw).

There is no way inductive charging was nearly 100% efficient, unless we consider something like 75% to be "nearly". The systems built into the road are even less efficient than this.

I got sidetracked and didn't look for the article I was thinking of.
And it struck me,that GM never said the charging system was close to 100% efficient,only the paddle-to-port transfer by itself.

I hope the drivers don't go to fast in the turns.

The November,2015,National Geographic's cover story was,
Cool it,The Climate Issue.
*They present Mark Jacobson's Road Map for the United States,starting on page 66.
Here's a breakdown of his vision:
1.3% Geothermal
0.1% Tidal
0.4% Wave
3.0% Hydro
7.2% Rooftop PV
30.7% Utility PV
7.3% Concentrated solar
19.1% Offshore wind
30.9% Onshore wind
-------------------------------------------------------------------------------------
On page 67,Stephen Brick,Energy Fellow,Chicago Council on Global Affairs says,
'It has zero chance.'
He prefaces his comment,indicating that the Road Map would run up against politics,regulations,social barriers,political influence of oil,gas,and coal industry.
Brick never argues the substance of the plan.
-------------------------------------------------------------------------------------
*The Road Map would be $15-trillion,spread over 35-years
*$428,571,428,000/year
*absorbed by 319,148,894 citizens
*@ $1,342.86each
*@ $3.44/day
*about the cost of a bacon,egg,and cheese croissant at a local Donut store.
-----------------------------------------------------------------------------------
Craig Welch,of Nat.Geo. comments that '...Jacobson's work at least offers a starting point.' Page 67.

I will just put up my own solar power I don't need the government to screw it up.

Roadmap to Nowhere puts the reality of the necessary hardware into perspective
.
1 million 2.5 MW wind turbines and 5,000 Solarstar sized 500MW solar farms together covering 130,000 square miles. $15 trillion. We already have $20 trillion in national debt that will never get paid back. And there would still be days long selctive black outs due to a very minimal amount of storage as part of the plan. And the electrolytic Hydrogen conversion of all heavy machinery and transport is just wishful thinking. As is the underground thermal storage system that is part of the roadmap. ect.

The Tesla BigF'nBattery in South Australia is running at 82% roundtrip efficiency.

I'm not sure that this is needed, though, to keep things safe. What was the rate of charging for this?

I think for higher charging rates, that direct contact of DC connectors is needed.

Aerohead said that it was 99%. I shared the picture because whenever I hear of inductive charging for cars it is from the ground.
