Improved version of my paper "How to fix global warming with cold fusion"

Several people offered valuable suggestions and corrections to my paper:

How to fix global warming with cold fusion

I thank them all. I would welcome MORE suggestions!

I went through my notes and added an Appendix estimating the cost of the megaproject. It was cheaper than I thought. It would cost about as much as we pay for carbonated beverages per year. For a little more than we spend on fizzy drinks, we can reverse global warming and improve the quality of forests.

I added another Appendix describing the likely cost and performance of drone wood chipping machines. It turns out my knowledge of drones was way out of date. I looked at the specifications for a 1 kg Autel EVO II drone. This is a commercial or “enterprise” drone. The motor produces 140 W. I assume a flying cutting tool would resemble this. It would clamp onto a tree, and then use the entire 140 W to cut wood.

How much can you cut with 140 W? I looked up how much energy a Diesel wood chipping machine uses. It is ~49 J primary energy per gram of wood. Then I cut 1 cm chunks from a two-by-four into simulated wood chips. I used a Black & Decker jigsaw with a KUMAN power meter. When it reached 0.010 kWh (36,000 J) I stopped cutting and measured how much wood was cut. It was 237 g. That's 152 J/g electrical energy. As expected, it is far less efficient than a big wood chipping machine. I assume a 140 W cutting machine would be roughly as efficient as the jigsaw.

Slightly creepy.

INCREASING CARBON DRAWDOWN AND RETENTION IN TERRESTRIAL BIOMASS USING BIOENGINEERED TREES - $500,000

The rate of photosynthetic assimilation and decay of lignocellulosic biomass currently limits carbon drawdown and retention in terrestrial biomass. Living Carbon is developing innovative methods to reduce the susceptibility of vegetative biomass to decay by lignin-eating fungi, thereby reducing the rate of release of carbon dioxide back to the atmosphere through fungal respiration. Living Carbon’s trees resist fungal decay through absorbing small amounts of nickel and copper from the soil and depositing these metals in their xylem (wood) tissue as they grow, which offers a biological strategy to mimic the pressure treatment process that forces copper-based preservatives into lumber to increase its longevity. If these results translate at scale, these trees will improve carbon drawdown on the gigaton scale when planted in managed forests, and lumber from these trees may not require costly and emissions-intensive pressure treatment.
