Light Beamer | Cost

The estimated cost of the laser array is based on extrapolation from the past two decades, and the prospects of mass production to reduce the associated cost.

Laser amplifier costs declined exponentially between 1990 and 2015, halving approximately every 1.5 years (18 months). If this this trend were to continue, it would bring the construction cost a large beamer orders of magnitude lower within the next decades.

    By firing these kinetic sails into comets or asteroids we could refine the sails control systems to a greater accuracy while working on our Starshot concept, sort of ironing out the details but at the same time providing benefits on the go.

    We will need at some point to invest in an asteroid/comet defence system, this laser at full power would pack a huge punch. We could fire these sail discs at high velocity to open the objects crust and allow either the Sunlight or laser power to disperse and move it. We could also use these discs to probe other objects around the solar system for study, it is all the other tasks this laser system could offer that makes it much more attractive. Starshot maybe just be the final goal but the amount of tasks completed in the mean time during that journey would be enormous."

    Answer:
    Thank you for your consideration. I agree with your comments thanks for all your enthusiasm.

    Answer:
    Thanks for your input and help. This is precisely what we were considering in the second phase of our project which we call the prototype phase. We anticipate this to begin sometime in the 2020’s.
