Space Solar Vs Base Load Ground Solar And Wind Power, John K. Strickland Jr.

Online Journal of Space Communication

This paper attempts direct comparisons between ground-based solar and wind electrical power generation systems and those of Space Solar. Ground solar and wind are the two major popularly proposed replacements for carbon-based energy. Potentially, these could become very large base load electrical power sources due to: 1) their current political recognition as the desired replacement sources and 2) to their widespread availability. However, they have severe physical limitations. For Space Solar, only those aspects that are critical for valid comparisons to the ground based systems are give attention. The focus is primarily on physical comparisons, such as actual areas of …

Costs, Organization, And Roadmap For Ssp, Peter J. Schubert

Online Journal of Space Communication

Space Solar Power will be too expensive until it is too late to afford it. Politicians shy away from projects that last longer than they will remain in office. Governments are reluctant to fund projects where there are no short-term paybacks. Militaries will not sponsor work that cannot be used to fight wars. Corporate investment in long-term projects without a proven return are unlikely. Environmentalists, status quo defenders, and established energy interests alike will resist large-scale projects, driving up costs and costing time. There is presently no consensus on an optimal SSP architecture; nor is there an agreed-upon cost; nor …

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. …

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 …

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 …
