I for my part will use the batteries of my EV in 8-10 years in my house to store solar energy - when the time has come to replace the battery. And your belgian professor should do the math again - if he exists at all. General consensus is that depending on the battery size, an EV will catch up the additional CO2 footprint after 20k -70k kilometers - also depending where the electric energy is generated from. |

EV cars are not "so much more efficient". They tend to be heavier, which requires more energy to move the extra mass down the road. The shift cannot happen in that time span without massive investment in generation and transmission capacity. That investment in a 10-15 year span will drive the cost of electricity to stratospheric levels. It would cost more to charge your EV than to buy fuel for your ICE. |

Electric Car question....

law of conservation of energy: The extra mass to move the car is only relevent in a minor increase of rolling resistance - EVs recharge around 60% of the kinetic energy. ICE vehicles don‘t, they convert the kinetic enegry into heat via brakes! ICE engines generate 70-80% heat and only 20-30% of the energy in fuel is transferred into kinetic energy - at best. |

Waiting an hour to charge my car is a deal breaker for me on a trip. I hate to stop, let alone sit there or waste time doing something else while I could be on my way. I'm sure this will get better..... Sent from my iPhone using Tapatalk Pro |

Lithium ain’t easy to get…
Algorithms with thousands of parameters from the type metals in an electric vehicle (EV) battery to the amount of aluminium or plastic in a car, plus ICE emissions as well, suggest the EV is more carbon heavy in the beginning. But once an owner has put 13,500 miles on their Tesla, the carbon footprint breaks even. After that, the EV is more effective vs ICE burning fossil fuels. So if you tend to trade-in every 2 years, EV appears to be only marginally better. Sent from my iPhone using Tapatalk Pro

Correct. Looks like a stock "mine" image. Here's one of a lithium operation.

Stumbled upon this on the Facebook. Thought of this thread.

the anti EV argument reads like someone getting out of a model T ford test drive today and saying ice vehicles are rubbish...
EV are still relatively young in development. ice has over 100 years. Stop comparing old v new. we need to go through a few years of poorish performance till they get it right but already EV are close to ice in performance and past in a few but in 5 years time they will be miles ahead on every level. sure the infrastructure needs updating but it's a chicken and egg situation and as battery power increases dependency on charging stations decreases. what was once 50 miles on a charge is now 300 miles and will become 1000 miles.. The rate of change is phenomenal |

No one can argue there are significant issues to be overcome until EVs are as reliable and convenient and cost effective as an ICE vehicle, but as Pointed out, we have had over 100 years with ICE and about 10 with EVs. These problems will be solved. Those that deny the inevitably of this change are just burying their head in the sand. |

It took something like 11 years from the Wright Bros first flight until the first commercial passenger flight around 1914 and until 1926 until the first 'schedules' passenger flights.
And I remember standing there at Kitty Hawk yelling....."it'll never get off the ground"..... "buy a bicycle"!!!! ya bunch of bloody morons!!!

Yeah, I'm in San Diego and see tons of Teslas, and some from middle America, like Kansas, and I have always wondered if there are many Tesla owners in the Mid West.

P.S. The future is Hydrogen not EV. Tailpipes emitting water is a beautiful thing. EV is a distraction and short-term revenue driver for battery producers and miners. The electricity infrastructure investment needed for full EV use, is impossible to ever achieve, even in developed nations. Will have the same impact as hybrids, it's not the game changer so many wish it to be. That desire also, doesn't change the underlying fundamentals of the heartstring story of dirty lithium-ion batteries saving the environment. Only metro areas will be using EV fully or at least to a greater degree. By the time EV infrastructure is ready for global use I doubt we will even be using human driven vehicles and instead mandated to use "safer" AI driven vehicles. Distant future. Will be shown in time |

And I find it remarkable that petrolheads are discovering their environmental conscience only when it‘s their turn to criticize EVs Continuing to burn oil is certainly the worst option. |

And we haven‘t even started about potential hazards - Hydrogen must be constantly cooled and tends to explode from a spark. To produce Hydrogen, you need an enormous amount of energy in the first place so it‘s a total waste of energy. Better use that energy to charge up EVs |

That is another interesting point, about Hydrogen powered versus battery powered vehicles in my (admit idly uniformed) opinion, I agree Hydrogen will be the final energy solution for vehicles. However, I think we have even farther to go with Hydrogen then we do EVs.

I'm developing a battery that will require more energy than it produces. It will be for rich people's EV's because they have the luxury of wasting energy to travel. These EVs wil be a status symbol. Any investors?

If they have sparkles and a thing that goes Ping!, I'm in.
