Electric vehicle: battery life?
Electric vehicle battery life will realistically need to reach 1,500 cycles for the average passenger vehicle, 2,000-3,000 cycles after reflecting a margin of safety for real-world statistical distributions, and 3,000-6,000 cycles for higher-use commercial vehicles. This means lithium ion batteries may be harder to displace with novel chemistries?

Model of losses in a solar cell: surface, emitter and shading?
This data-file calculates the losses in a solar cell from first principles. Losses on the surface of the cell are typically c4%, due to contact resistance, emitter resistance and shading. Sensitivity analysis suggests there may be future potential to halve silver content in a solar cell from 20g/kW to 10g/kW without materially increasing the losses…

Energy economics: an overview?
This data-file provides an overview of energy economics, across 175 different economic models constructed by Thunder Said Energy, in order to put numbers in context. This helps to compare marginal costs, capex costs, energy intensity, interest rate sensitivity, and other key parameters that matter in the energy transition.

Global energy market model for the energy transition?
This data-file is a global energy market model for the energy transition. It contains long-term energy supply-demand forecasts by energy source; based on a dozen core input assumptions. Total useful energy consumed by human civilization rises from 80,000 TWH pa to 140,000 TWH pa by 2050. The mix is 30% gas, 30% solar, 15% oil,…

Groq: AI inference breakthrough?
Groq has developed LPUs for AI inference, which are up to 10x faster and 80-90% more energy efficient than today’s GPUs. This 8-page Groq technology review assesses its patent moat, LPU costs, implications for our AI energy models, and whether Groq could ever dethrone NVIDIA’s GPUs?

Data-centers: the economics?
The capex costs of data-centers are typically $10M/MW, with opex costs dominated by maintenance (c40%), electricity (c15-25%), labor, water, G&A and other. A 30MW data-center must generate $100M of revenues for a 10% IRR, while an AI data-center in 2024 may need to charge $5/EFLOP of compute.

Computer memory: aide memoire?
Three types of computer memory dominate modern information processing: Flash, DRAM and SRAM. This 5-page note simply covers each one, how it works, what it costs, advantages, disadvantages, market sizes and leading companies. AI likely boosts all three, but can more SRAM unlock big efficiency gains?
