- Each terrorist killed becomes a martyr and great tool to recruit more terrorists. In sum, killing terrorists is counter-productive.
- Attacking other nations to rob them of natural resources like oil provokes them to fight back. Cost of both renewable energy and electric vehicles has come down in past six years. It will soon be cheaper to buy wind turbines, solar power systems, and parts for national smart grid to replace 80% to 90% of our oil powered transportation with electric vehicles than to fight over oil.
- They have looked at climate change and decided they would rather divert money from military pork to buy renewable energy equipment to sell to electric utilities on 30 year mortgages than cope with hordes of climate refugees.
If we are drilling through bedrock - and according to MIT in Future of Enhanced Geothermal Systems most (maybe 3/4) of all bedrock with geothermal resources worth drilling for, is granite, which takes a nice polish with an oxyacetylene or arc welding torch and leaves a nice glassy finish, that might be seal enough to hold CO2 down at 4 km or more below surface. If, instead of rock flakes, wells with even parts spaced to extract geothermal heat and replace fracking are likely to need to be lined with stainless steel well liners and 2 inches of thick cement, reducing diameter to 8 inches from over 12 inches. Another possibility is that leaving a solid slab of bedrock with injection and production wells through it, well cemented in place, might put enough of a lid on hot rock reservoirs to make it unnecessary to worry about leaks within bedrock. Then we actually might be able to frack safely.
With 60 m spacing, 3 spirals add up to 20,736 linear meters. With conventional drilling for a 10 km deep geothermal well at $20 million 2004$, that comes to a cost of $2 million/km about $41 million to substitute drilling for fracking for one 5MW geothermal reservoir. Let us hope it is possible to frack geothermal wells without leaks. MIT also says 0.5 km3 (about 100 MW) of pore space holds 260 million metric tons of CO2, the equivalent of 70 years of 500 MW coal-fired plant; but that's a 'drop in a bucket' compared to 5-6 billion metric tons of CO2, which =s annual emissions in the USA, about 40 billion/year for world. With federal governments offering to pay $50/metric ton for putting CO2 underground securely so it won’t leak for a thousand years, the cost to capture and compress CO2 to persuade frackers to use CO2 and leave water for farmers is completely covered. The world as a whole needs to go beyond net zero emissions to clean up some 40 trillion metric tons of accumulated CO2 before catastrophic climate change damages farming too much to feed the world's population. Since the USA has the most nearly viable economy, the USA should pay much of the cost. Since its military wants renewable energy more than weapons, why not divert some money from military pork to both renewable energy and CO2 capture and storage? Retooling the economy in this way will be the most logical, healthiest tactic for everyone.
