(Note: this is an example of my Science Fiction adventure writings involving peoples' struggles to cope with various energy crisis. The novel from which it is extracted, "Building Up" by J E D Cline, includes many energy coping references, as do my other Science Fiction writings which are available in my various blogs.)
Day 29 of 30 (November, 2006)
The construction and use of the space access structure was energy starved. As there were no electric power lines existing servicing Cayanbe, the Ecuadoreans pitched in and got a powdered-coal fueled electric power plant brought in to the construction site, and while that fuel supply lasted, they could speed up the scaling up construction of the structure. At some point they would need to shift to using energy resources for lifting materials up to GEO to build a Satellite Solar electric Power plant, with which to power the transportation structure thereafter.
The supplies available to fuel the coal-powered electric power plant were rationed and getting less each week. So when the diameter of the KESTS structure to GEO reached 36 cm, they called a temporary halt to the scaling up process. At this point the mass of the structure was 4E10kg, and the structure was capable of receiving 600 megawatts per hour while lifting 20 million kg of mass to GEO each hour, so it was extremely underused, being only powered by the small powerplant on site. And that powerplant was running out of allowed fuel ration, too. They had to get to building the solar electric powerplant built in GEO as soon as possible.
They had instructed the old dual wheel space station to be towed to where it could continually beam microwave energy to rectennas to either the White Sands location, or to the Cayanbe location. They arranged to time share the energy beamed down from its solar power source, a kind of SSPS, but welcome addition to the petrochemical powerplant. They used the energy primarily to lift the construction materials for a SSPS capable of delivering 600 MW of solar-sourced energy continuously to the earth surface, If they could achieve that before their earth sourced energy supplies ran out, they could at least run this KESTS at full capacity, building more solar electric powerplants, and start negotiating with countries for delivered electric power, and start having an income. From then on, things would be easier.
As it was, the combined energy input from the coal-fired electric power and their average share of the space station's beamed energy was only half a megawatt, with which they could only deliver 15,000 kg to GEO each hour. They chose to build the main structure of the powerplant out of glass cast in a hard vacuum, which had enormous strength to mass ratio, far greater than the finest steel or aluminum, so long as it could be kept free of the atmosphere's molecules wiggling into glass surface microcracks, wedging into the glass until it was as fragile as it is normally on the earth's surface. They chose to melt the glass down at the KESTS ground terminal, and haul it up to the GEO construction site while still in the melted state, for feeding the extrusion facilities making the SSPS.
The structure had severe limits to the amount of concentrated load it could carry, however. It was very efficient at lifting a fairly continuous series of payloads of about equal mass, but the limits to concentrated mass load meant that they could not just haul up a solar powerplant ready-made. So Improy and Catalie went up in their little two-person spacecraft again, this time being lifted up by the KESTS, about its limit of a concentrated mass load. They only had a brief time they could work in GEO, being without passive radiation protection, and the injected DNA repair substance formula had long since been lost. So they used their space worksuits to assemble the solar-electric power panels into the glass main structure, and connected it to the microwave beam generator.
Looking down from the construction site, in GEO above the opposite side of the planet from the Ecuadorean mountain tunnel site, the world looked mostly watery. They were out of touch with ground facilities, and they dare not try to link into any internet signals that might reach up here. They then set up the silicon solar cell automated fabrication plant, which liked to be in zero g and hard vacuum, solar powered. Then they hurried back down the KESTS back to Cayambe peak tunnel, for a well earned vacation.
