My Analysis, Transcript:

The key economic factor in any space venture is weight. At $30,000-$15,000 / Pound. There is just no way that SSP can ever compete with low-tech terrestrial based solar power, which is constantly advancing in efficiency and decreasing in price. As long as spacecraft continue to use engines based on conventional physics the cost of sending a payload into space will remain relatively the same. Ironically, the propulsion problem is also an energy problem, so if we were capable to making an engine that can produce so much energy cheaply, it would be far more economical to use that technology to generate power here on earth, rather than send cargo into space.

The biggest weakness in SSP architecture is the necessity of shielding. i.e. protection against micro meteors and other space debris; Solar power = surface area = shielding = density = weight = cost. Similarly high tech = high cost. While the true value of solar is that it is inherently low-tech and therefore low-cost.

The whitepaper fails to produce any truly speculative advantages, the kind that you would expect, given the extremely speculative nature of the concept:

One thing I’ve mentioned before in other articles, extremely low temperatures allow for use of superconductors, but only from the point of the solar array to the earth’s upper atmosphere; so the value there is mostly negated. Not that they even bothered to mention this as a possibility.

As for incentives, they use the preposterous circular argument that the best justification for SSP is to achieve cheap and reliable access to space! The rest of the proposed advantages are far more absurd. However none of that matters because the annual global terrestrial solar fall is 800 TW (terawatts). With our current total consumption being only 15 TW, a factor of 53, it’s quite clear that space based solar power is nothing more than another lame ploy by the aerospace industry to appear relevant in a post-space-age world.

What exactly makes space so special? Aside from earth orbiting satellites I challenge anyone to name a single ubiquitous resource or product that is the direct result of our, or anyone else’s space program. Furthermore I’d even be satisfied with a short list of future benefits, uming that we continued sending people and equipment into space for the next 100 years.

Although it’s quite popular to refer to any time period post 1957 as the “space age”, aside from lots of pretty pictures, we have yet to see any concrete benefits from our astronomically expensive exploration attempts. Don’t get me wrong, I’m not against real space exploration. What I am against is our preemptive, stone-age version. It doesn’t take a genius to see that rocket propelled spacecraft are far too primitive and impractical for reliable intergalactic travel, even within our own solar system.

This is money that would be far better spent on physics research. Realistically, there should be a moratorium on space exploration until two key technologies have been realized. 1) Faster-than-light locomotion. And 2) Maintenance-free shielding that can withstand the extreme conditions of space.

Make solar panels:
The fact is that most people don’t know about the benefits of generating renewable energy themselves. They also don’t know how easy it is to do this.

They just pay $1,000s a year in electricity without having a clue that there is a much better way…
The Easiest, Cheapest Way
To Generate Renewable Energy

There are many solutions to produce renewable energy.

However, most of the products are not designed to produce the electricity needed for home supply. They cost fortunes and are only usable in the corporate world.

Some companies have developed products for generating home wind power or solar power, but they cost $1,000s for only one product. And this doesn’t even include installation.

Luckily this is where we come in. HomeMadeEnergy.org will teach you everything you need to have your own solar or wind power system for $200 or even less.

I’ve made countless tests to make sure that these are the most effective methods for producing heaps of energy.

And once I had these plans, I wrote them out professionaly for the “average Joe”, with plain English words. Anyone can understand and use them. (Even a 15-year old kid!).

And before releasing them in a guide, I’ve given them to many test subjects to see if all of them can succeed in generating enough electricity to power their home. How Would You Like To UNPLUG Your
