Question: What's the production if the technology is sodium-sulfur batteries and yes to toxic materials?
SQL: SELECT "in_production" FROM energy_storage_specs WHERE "toxic_materials" = 'yes' AND "technology" = 'sodium-sulfur batteries'

Question: What are the moving parts of lead-acid?
SQL: SELECT "moving_parts" FROM energy_storage_specs WHERE "technology" = 'lead-acid'

Question: What's the room temperature with no toxic materials and no ln production?
SQL: SELECT "room_temperature" FROM energy_storage_specs WHERE "in_production" = 'no' AND "toxic_materials" = 'no'

Question: What's the technology when there are no moving parts but yes to toxic materials?
SQL: SELECT "technology" FROM energy_storage_specs WHERE "toxic_materials" = 'yes' AND "moving_parts" = 'no'
