You really think it will be costlier to extract those metals from the used batteries than from Earth? Lithium, for example, is 7% of battery's weight. Guess the Lithium concentration in the brine they extract it from? They are lucky to get 1%.

I've lived all my life in India. Do you know what an idling diesel engine spews out? Huge amounts of particulate matter, NOx, CO, not to mention the CO2 that's boiling our planet.

Emissions are not a concern? Are you living in Mars already?

That's called a train/tram and I am a big proponent. Wherever feasible, we should have more trains.

Nope, more and more Lithium mines are set to begin production in the next few years. That 4x price had a huge impact on the investment environment of Lithium mining. There will be a glut, especially with China's economy taking a major hit.

This is something all developing countries will discover: electric vehicles are much less complex machines and can be built with a far smaller capital expenditure and technology transfer.

This won't happen in the immediate future because almost every Li-ion cell produced right now is spoken for. However, once there's a glut of cells in the mid-20s, there will be free for all for all adventurous businessmen to start EV assembly. Quite similar to what we saw in the 2014-2017 era when all the cells weren't scooped up by the Teslas and BYDs.

My life and that of all other Indians has improved immeasurably under Modi government. We live here, so we know the insane infrastructure growth, the lessening corruption, the growth in our stature at the world stage.

We are happy with him, thus we will vote for him. BBC apni ma chudaye :)

Salt is the result of violent, hate-sex between Acid and Base.

It would be a paradise for cows, I tell you. Chilling around in the shade, eating grass, sipping the dew dripping from the steel frame.

Thermal batteries will lose out to flow batteries or even old lead-acid batteries. Too many steps to charge/discharge such batteries, to many losses at each step. Thermodynamically, not the best strategy.

The panels can be raised further to accomodate the cows, who will definitely not knock them down.

I was hearing the Fully Charged podcast recently, and a guest said something so simple and yet so optimistic. We don't have to be 100% renewable, we just have to 90% renewable and there is huuuuge difference between the two. The latter can be done even with today's technology. Keep the peaking plants online for emergencies and all. Just don't burn fossil fuels in them until its absolutely necessary.

Remember, almost half the emissions ohr civilization has made, have been absorbed by natural systems. We cannot push the Earth much further, but we can also expect to see significant changes in CO2 levels as the emissions go down At 90% reduction, across the board, we can expect to be on a permanent path to pre industrial CO2 levels.

Excess wind/solar can be stored as hydrogen, at much lower cost compared to batteries (although in a much larger volume if we're talking about low pressure safe storage). It can then be fed into the local heating grid. Unsure about long distance supply since Hydrogen makes steel pipes brittle.

I heard a conspiracy theory, which sounded kinda logical to me. The Canadian sikhs want to portray Indian government as anti-Sikh so they can be considered as a persecuted group in the eyes of Canadian government. This would help them in bringing over their family members on work visas and all.
