Space Based Solar Power Generation.

Click For Summary

Discussion Overview

The discussion centers around the concept of space-based solar power generation, exploring its feasibility, potential benefits, and challenges. Participants examine the implications of a Californian company's initiative to harness solar energy from space for electricity supply on Earth.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant notes the significant obstacles, such as high launch costs, but highlights that a utility company is interested in purchasing the generated power.
  • Another participant expresses enthusiasm about the potential for increased solar energy capture in space, mentioning concerns about maintaining sunlight exposure due to Earth's rotation and the need for geosynchronous positioning.
  • A different viewpoint suggests that the power company's agreement to buy power does not necessarily indicate the project's viability, as companies are often legally required to purchase power from generators.
  • One participant references a past successful experiment with a solar-powered microwave power receiver, indicating that similar technologies have been tested, although concerns about safety and alignment are raised.

Areas of Agreement / Disagreement

Participants express a mix of excitement and skepticism regarding the feasibility of space-based solar power. While some see potential benefits, others question the viability and implications of the power company's involvement.

Contextual Notes

Participants have not fully explored the technical and economic challenges associated with launching and maintaining solar power systems in space, nor have they resolved the implications of legal requirements for power purchase agreements.

A Californian company is aiming to capture sunlight in space to generate a regular supply of electricity on Earth.

There are significant obstacles to overcome, like the high cost of launching things into space, but California's largest utility has already agreed to buy the power.

I know that this has been proposed as a possibility for large scale power generation for many years, but according to this new article it seems that at least one power company is very serious about getting this up and running in the very near future.

Any thoughts on this? Do you think it will be successful?

This would be amazing! you can get soooo much more solar energy from space than here on earth, and there would be no clouds to block the sun, although with the rotating of Earth I don't know how it would stay in the sun light unless it wasnt in geosynconism or however you spell it ha ha

Power companies are, for the most part, requried by law to buy power from anyone who generates it, so the fact that the power company has agreed to buy the power is completely meaningless. It doesn't tell us anything at all about how viable the project is.
 
Yes we can, and have. For many years a "solar" powered microwave power receiver ran successfully in the parking lot of the pentagon. It was removed some years ago I didn't hear that it fried anyone. Seems if a space rock tapped it it might light something up needs a good kill switch on-board auto off if misaligned.
