The technology gap shall keep growing wider once this book comes out. I have 32 categories of new gadgets, but I want to focus on the planet's big picture in my limited time. We'll curb fossil fuel use and we'll curb the planet's exponential feedback loops. The best place in an existing house or building to store heat is usually the center of the lowest floor. I already do that in my zero fuel, off-grid West Greenwich greenhouse. The greenhouse is sustainable and quite affordable, also inherently low humidity plus 150% of weak winter sunshine. It turns out that a strong enough solar lighting/heating system can triumph even over weak insulation and a few single pane glass windows - now that's an effective system! Pictures are at klinkmansolar.com Architects never think of insulating the center of a concrete basement floor because the local subsoil insulates well. Putting even an extra 10 degrees C. of heat into the existing concrete slab and the subsoil below it will store much of the heat for days. Optimally a heat pump draws on this slab at night to heat a building's second floor heating zone. I don't see why an economical 90% fuel displacement can't be reached. I have designed a modular mat that lays on the concrete slab for good heat transmission into and out of the slab while insulating the room above from this heat. A big box store or a factory can have one section of their floor slab reserved for heat storage and another section, preferably near a big freezer unit, for coldness storage. Why overpay for electricity? Dessication to prevent all mold growth is vital, just as dessication is a vital engineering problem inside any refrigerator/freezer. I solve a critical solar cosine angle problem by deploying multiple solar receivers for every heliostat. My heliostat mirror surfaces are sectioned to generate small sections of slightly concentrated near-parallel light. They aim at my insect eye receivers. Each receiver section bends the light (think of light getting bent in optical fibers) using many thin, parallel sets of reflecting surfaces. This light-bending lattice also happens to exclude all birds and bats. At the far end of each receiver, a mirrored tunnel filled with near-parallel concentrated sunlight carries the sunlight to its destination. These mirrored tunnels can be merged into megatunnels perhaps 4 meters high by 3 meters wide, for industrial heating purposes. We can gently shrink the widths of these tunnels at the back end to create extreme solar concentration that achieves industrial strength temperatures. We absolutely must enhance the refreezing of our planet's remaining permafrost in winter, or else. I recommend simple air pipes that move the Arctic midwinter wind underneath winter's insulating snow pack. We need to enhance winter pack ice formation on the Arctic Ocean. My wind-powered seawater pump boosts itself up on its ice pack after it creates each few inches of new ice on top of the old ice. Normal is perhaps 14 feet of sea ice depth. Real white snow is effective. White paint wouldn't deliver the same environmental side effects. Arctic restoration will be expensive for the world, but not one thousandth as expensive as doing nothing. An airdrop of water in the middle of a megafire is still an energy hog. We need many new energy-efficient ways of inhibiting megafires. We need to stop the megafires before the West dries up further. We also need ecological restoration. Some of this restoration work we can do quickly, and we should understand our goals here. I have Rhode Island Solar Energy Association memorabilia in boxes in my basement. I inherited them from Domenic Bucci, long-time RISEA President, after he died. Domenic was my mentor during my early greenhouse prototyping.
