True, an overall 10% improvement is a big number, one order of magnitude is SF now.
But for single technologies, more than 10% is possible, internal combustion engines vs electric, incandescent light vs led..
So reasoning on the global efficiency (resource and energy use, recycling of materials, capture of wasted energy, ) is the mainline to go.
IN nature photosynthesis is around 100% efficient.
- genocidicbunny 3y ago> IN nature photosynthesis is around 100% efficient. If your measure of efficiency of photosynthesis is how much sunlight is turned into chemical energy, its in the low single digit percentages. C4 photosynthesis is something like ~4% efficient, C3 is lower still.

- effed3 3y agoOps, true, overall photosynthesis is low, i remembered some higher capture eff. at some wavelenghts.. (just retina photon conversion is about 50% IIRC)
