Naysayer changes mind on electric car

Lithium costs $20,000 a ton, I assumed you needed one ton per electric car, there is only enough Lithium for 65000 cars on earth at that rate. Old electric cars were thrown away as the battery was worth more to replace than the car. It was a no flyer right.

Wrong, only 10kg of Lithium is used per electric car, Tesla recycles Lithium from batteries properly. Currently only disadvantages to petrol are range and charge time. 

Also hydrogen vehicles waste a lot of energy pumping hydrogen upto very high pressures near 1000 atmospheres I don't want to be near the tank when it explodes after hitting a rock on the road. Hydrogen leaks under pressure being the smallest molecule being much harder to contain than water. Metal hydride storage avoids the pressure at the extra expense of carring around metal hydride to store the hydrogen molecules.

Also electric tesla charging stations should be built around solar panels, electricity wind turbines, and small hydro electric generators, people should then have a https://pumps.ie like websiite giving in real time the storage of the stations supercapicitors or battery saying whether the station is ready to charge a vehicle and this added to google maps and automatic car driving so that fuel can be filled practically for free on relevant days. It costs 3 million euro to run copper wires 2km to an electric transformer. So the charging station will need a tow car in case a vehicle gets stopped on the way up also decent roads need to be built to the wind turbines or wires run to a suitable location.

Farmers can negociate with wind turbine installers to put in a free charging station for electric tractors.

Win win win

The future of worldwide power


I thought I had an original idea, I did not but we could have free power worldwide using Solar Energy after the infrastructure is paid for and maintained as the Sun is always shining somewhere on the Earth, have a look.

We could transfer power from where it's Warm and bright to where it's cold and dark.

As of August 2023 there is room temperature semiconductors allegedly very important for this idea, this has to be verified by other scientists see video below. 


 



I personally feel this endeavour is being stopped by Big Oil.
Obviously other forms of free energy Hydro,Wave,Wind would help.
All thats needed is cables from the Sahara across the Meditreanean near Gibraltar, the Baring Strait & down to Australia via Indonesia by far the longest cable.

Lithium as used in Lithium ion batteries costs $20,000 a tonne and it has a lot of disadvantages. With a global power grid you dont need expensive exploding Lithium Ion batteries which fail every two or so years to power your House overnight from Teslas solar panels which work well in good weather. Power for  Electric Cars can be picked up from electric cables under roads like the iWatch's charging mechanism and the usual pessimistic 100 miles per charge Lithium Ion batteries can be used on minor roads.

Copper is expensive for the big underwater cables and heats up and causes power losses but this looks promising in the future.

This is the future God knows how much fossil fuels we have left maybe 30 years is a reasonable guess & it's a horrible to be wasting fossil fuels when we need it more for other stuff. The Sun will stay going for another 8 years & I think forward thinking Investors should stop looking at Oil & get going with these Fantastic Technologies.

Alternative uses of Solar Reflectors in Deserts without distributing it for electricity would be to use it to melt steel or convert plastics or used tyres back to Oil at high temperatures here is one example.

Please feel free to leave a comment if you wish to discuss these ideas further, if you are interested in collabarating with me on a venture.

Elon Musks Solar City will be viable, however, if John B Goodenoughs new Sodium Battery or similar takes off as this be a lot cheaper than the Batteries for houses Solar City is currently making for powering houses when the Sun isn't shining. Also, there is only 64 million tons of Lithium mineable in the world, enough for 64 million electric cars, and not much else, and, not much energy seems to have gone into recycling Lithium ion batteries.



Solar panels typically use silver for wiring and we are running out these copper based solar panels with record efficency are a in my opinion a risky but very hot investment depending on how good these guys are in a Shark Tank.
