A battery for a changing climate. OK. So I was getting all excited about outback 'Adventure' transport and Mars space research (see 'Blogs') when it occurred to me that the ol' golf buggy could be due for a retrofit with biochar. Maybe it's time to upgrade the ol' golf clubs and retrofit a golf buggy with a prototype solar generator/powerbank and solar roof that I've been thinking about for a while.
Here are some potential tech specs:
Solar panel roof made from 'flash graphene'/twisting chromophore PV cells/'hot carrier' Perovskites embedded in a biochar-based biocomposite
A biochar bybrid solar generator/powerbank with the following considerations:
high Coulombic/Faradaic efficiency
durabiity eg. vibration, operating temperature range: subzero to 60 degrees (climate change is a bitch but no reason to stop playing golf, maybe in a space suit)
high 'depth of discharge 'DoD'
many lifecycles at high performance eg. 10,000+
high energy density
modularity eg. easily drop in battery replacement
maintenance - minimal or none
biosubstitution and biomimicry
energy management system (EMS) with colour LED touch panel:
Short circuit protection,
Over temperature protection.
Over discharge protection,
Over current protection
Australian 'green' electronics eg.Carbon-based, for future iterations
Universal battery housing and electronics that can integrate with different feedstocks for electrodes and different Carbon/Hydrogel solid-state electrolytes
Other tech specs:
-bamboo biochar with steam activation then doped with bamboo leaf Si nanowires (loads of Si rich Phytoliths/PhytOCs/Plant stones in the bamboo and Si from the bamboo leaf hypothesised to increase Coulombic efficiency) eg. Electrical Conductivity of Carbon is 1*10^5 S/m and Silicon is 1*10^7 S/m
LI: What if you could combine raw biochar with raw Silicon and make artificial Silcon Carbide (SiC) nanowires then create a matrix with turbostratic 'Flash Graphene' made from raw biochar?
1-graphene-like substance solid state electrolyte (with steam activation)
2- 'flash graphene' from biochar (or trash/rubbish) combined with a) ceramics, b) mesoporous Si
3-reclaimed biochar used as a sorbent for heavy metals eg.Ni, Cu (wastewater from mining)
-3D printed biochar-based biocomposite polymer shell
NOTE: At the end of the lifecycle, the electrodes, electrolyte (with the exception of 3 which could be added to concrete) and shell can be added to compost/Permafert/soil for growing plants, locking up the Carbon and Silicon in PhytOCs, or Carbon and Silicon in a biochar or Graphene matrix, for millennia to millions of years reducing the impact of climate change acceleration
NOTE2: Nanowires could be potentially harvested from exoelectrogenic bacteria and replace the Si nanowires bonded to the bamboo biochar. This could be a cheaper source of nanowires though probably less conductive than the Si nanowires
NOTE3: Silicon Carbide (SiC) nanowires could either be coated on biochar or graphene for the electrodes. They have some very interesting properties! Or, SiC could be formed on the biochar matrix using molten Si
NOTE4: Phytoliths are crystalline structures. Crystalline structures increase conductivity. Conductivity is a desirable property for electrodes=BINGO!! So, one race could be to find a bamboo variety that has the highest density of phytoliths...
LI: what if increasing the surface area of phytolith-rich biomass eg.bamboo/grasses increases access of electrons via ?electron hopping, to the phytolith crystal (which increases conductivity)?
LI: what is the 'sweet spot' for temperature of pyrolysis and steam activation where the C is reasonably ordered and the phytoliths don't lose their structural integrity?
What about an overview of the hybrid solar generator/powerbank possibilities?
Why not an all-kelp solid-state supercapacitor?
Sustainable kelp farming, anyone?
