BYD. Seagull or the seal. Can’t remember which one.

Embedded. I’m currently writing software with 96 bytes of RAM. My next project I get to splurge and have 8kB of RAM and 32k of Flash.

I’m more scared with how badly I’ll handle/manage the 8k of RAM.

If you are on a tight budget and care about the environment buy used.

Might need to wait for approval to do that.

Sodium batteries look great. They also can use the same manufacturing equipment as lithium batteries. Reducing the capital costs for the product.

They’re more of a hybrid technology. They have some great applications.

Like temporary storage when using regen from a car. They can buffer the energy and help with a rapid acceleration.

Dash cam in a car. They can charge the cap and in the event in a malfunction / event. The camera can continue to record.

Solar lamps. Charge during the day. Release energy during the night.

They’re poor at long term storage. Great at fast and temp storage.

The really short version: potential power savings.
