Direct electrosynthesis of sodium hydroxide and hydrochloric acid from brine streams | Nature Catalysis
recycling output brine from desalination plants to make sodium hydroxide in bulk. Apparently desal plants normally have to buy it to adjust input salinities, so producing it's own makes some sense...

Efficient CO2 Utilization via a Hybrid Na-CO2 System Based on CO2 Dissolution - ScienceDirect
Converts CO2 to hydrogen and baking soda via electrolytic cell and aqueous solution. Dependent on the aqueous solution though, where does that come from, how hard is it to regenerate, etc. Makes power too

Carbonized-leaf Membrane with Anisotropic Surfaces for Sodium-ion Battery - ACS Applied Materials & Interfaces (ACS Publications)
So a baked oak leaf turns out to be a decent sodium battery electrode. A bioengineered oak leaf that is easier to harvest/use would be an interesting base from which to build battery parts.

New Sumitomo Electric Battery 90% Cheaper Than Lithium Ion -Nikkei
The interesting bit is a sodium based molten salt that melts at 57C, which is very low and potentially in the range of a hot water heater. As an example, a home natural gas fuelcell feeding a high temperature hot water heater that envelops a home molten salt battery.

MSU News Service - MSU: Baking soda dramatically boosts oil production in algae
Interesting result, but they failed to do the simple check of seeing if simply bubbling CO2 gas through the algae grow medium fluid at the same critical timing would result in the same increase in performance. Specifically, is direct stimulation/fertilization of algae with carbon dioxide sufficient, or is the chemical pathway being used here specific to free swimming carbonate in solution.

Technology Review: TR10: Liquid Battery
Interesting idea, but what about the fundamental principal of batteries, being that you get better energy density by increasing the surface area of the electrodes? Wouldn't the liquid electrode layer represent the least amount of surface area possible?
