Well ... battery improvements will revolutionize everything. From big battery packs for renewables buffers to return to propeller based aircafts, and maybe even a tablet that could last a whole day linpack-ing. The problem is that we have evolution now while what we need is revolution. We need order of magnitude more density achieved without the use of rare or exotic materials.
