I like that one :)

It's too early to compare costs yet. Sodium is indeed more readily available than lithium, and 3000 cycles is a lot - but this needs to be verified. There was a lot of noise around super-long life of Li batteries when they first came up. Now that thousands had been sold with electric bikes, an average reported life came down to mere 600 cycles. Electric cars fare better because they are not discharged below 60-70% SOC.
