Solar Power Satellites Research In China, Ji Gao, Xinbin Hou, Li Wang

Online Journal of Space Communication

In its long-term vision, the responsibility for ensuring China's food safety for its huge population, meeting its international obligations for environmental protection and providing the structure for its energy needs have determined that the direction of future development of low-carbon energy sources cannot be to sacrifice the "inner" earth. Thus, the state has decided that power coming from outside of the earth, such as solar power and development of other space energy resources, is to be China's future direction.

Space based solar power (SBSP), and the development of solar power satellites (SPS) to facilitate renewable energy production, is one of …

Sustaining India's Economic Growth, Raghavan Gopalaswami

Online Journal of Space Communication

Depleting fossil fuel reserves and the tangible impact of climate change have mandated nations to review national energy-mix policies. The Government of India's target of 7% GDP growth rate will require 1,476 GW installed power capacity by 2052. But historical constraints since 1951 on growth of power capacity (like land acquisition, water, fuel supply chains and silting of dams) have limited power capacity growth in India to a maximum 4GW/year. Should these historical constraints continue into the future as "business-as-usual" scenarios, just 472 GW would have been realized by 2052, effectively slowing India's GDP growth rate to 3.5% per annum. …

Global Warming In Perspective Understanding Climate Change In A World Of Contradictory Information, John K. Strickland Jr.

Online Journal of Space Communication

This article attempts to answer some fundamental global warming (GW) questions in as clear and balanced a way as possible. It touches on the current media and political discussion of the topic, an understanding of which has become integral to understanding the topic itself. This discussion is presented in light of the frequent use of the global warming crisis as an argument against all uses and sources of energy, clean or dirty, by rich and poor. The extremely large untapped energy source represented by Space Solar Power is offered as a potential long-term solution.

Energy Costs Eliminated By Satellite System, Joleroy Gauger

Online Journal of Space Communication

Successfully implementing a Solar Power Satellite Program will take a multi-discipline, multi-national, geopolitical effort. Planning for that level of complexity must begin now. This article gives the principal reasons for going to space for "free power," and seeks to illustrate some of that complexity. Solar energy is "free", just like the water in a hydroelectric system. There is no cost for fuel.

The sun delivers energy to earth at the rate of 1.37 kilowatts per square meter during daylight hours. This amounts to 174 petawatts (one petawatt is 10 to the fifteenth power). About 89 petawatts reach the earth's surface. …

Harnessing The Sun: Embarking On Humanity's Next Giant Leap, Feng Hsu

Online Journal of Space Communication

It has become increasingly evident that facing and solving the multiple issues concerning energy is the single most pressing problem that we face as a species. In recent years, there has been extensive debate and media coverage about alternative energy, sustainable development and global climate change, but what has been missing (at least in the mainstream media) is the knowledge and point of view of scientists and engineers. From the scientists or engineers perspective, this paper discusses the prospects for mankind's technological capability and societal will in harnessing solar energy, and focuses on the issues of: 1) space based solar …
