The suns first converts nuclear to thermal energy (a thermonuclear conversion) and then the termal energy to photonic energy (a photothermal conversion - via Stefan Boltzmanns radiation law). On earth this photonic energy gets either captured by photosynthesis (a photochemical energy conversion - with a little hidden electrical intermediate step) or it gets converted back to heat again (again photothermal). This lower level heat may drive winds via pressure gradients (a thermomechanical conversion) and vaporize water (partially a thermoenrropic conversion). Wind convections may then lift up water vapor and water droplets in clouds (a mechanogravitative conversion). When the water finally rains down and flows down rivers it is converted back to thermal energy that is so much devalutaed that it becomes practically unusable. At the end it is becomes irradiated as infraread light at night into the three kelvin cold space.

This article is a stub. It needs to be expanded.

Advanced mechanosynthesis can provide today's missing link of efficient chemomechanical conversion. This makes long term storage of huge amounts of energy possible. Additionally chemical energy is easier to transport than electrical energy - even today (oil tankers).

Limits

Unlike other performance specs like transmittable power density. The energy density of chemical energy storage is (with gasoline and explosives as good examples) pretty much at it's limits with our current (2016) crude technology.

Advanced atomically precise technology allows now forms of chemical energy storage that at the cost of slightly lower energy density are far safer and allow energy conversion efficiencies very near 100%.

For energy densities higher than chemical only nuclear is possible. How and in how far advanced atomically precise technology may enable us using some nuclear physics as a bidirectional battery is very unclear at this moment (2016). See APM and nuclear technology for related highly speculative thoughts.
