    Looking at doing StarShot purely with solar will not be cheap. Here's Tesla for example:
    https://www.youtube.com/watch?v=L_OF1Loax_4

    The spec is (roughly) 50 GW for 2 minutes, or 1.6 GWh total.
    That's about the projected total annual output of Tesla Megapack storage.

    Adding solar arrays into the mix (of course), by 2022 Tesla may have a projected total annual output of 1 GW.
    That would mean about 2 hours minimum to recharge that 1.6 GWh Megapack.

    It would be easier to colonize the ocean floors here on Earth.

    Did you follow the link? It's about locusts in Africa.

    Well, you might need to build a special habitat for them, under a mile of ocean water.

    one third of too long is still too long?

    you will not be able to get enough food water,air or sanity on board to survive the trip.

    No humans aboard.

    Maybe a few roo-bots?

    what would be the purpose except knowledge?
    we can pretty safely assume that we will continue to improve all facets of space travel.
    imagine taking the risk to push the travel limt out just 3 or 4 times thew present limit and safely arriving to a thriving civilization that the original colonists left 3 years after you did in a much faster safer ship.

    Today the reachable universe for man stops at the moon
    the universe we can see extends a short time into the past.
    The light from the closest star is about 9 minuets old when it arrives
    99.9999999999% of the stars we can view we are looking at what and where they were before man even existed

    Astronomy is the study of galactic history.

    Trouble with a super fast speed is you have to slow down, or do you?

    Start off with a large unmanned slow vessel using nukes in outer space, follow that up with faster smaller spacecraft that crash into the pusher plate this would add momentum and hopefully useful material.

    More delicate material could be delivered by laying a trail of electrified dust, the following spacecraft would scoop up this dust and slow down enough to dock.

    Near the destination the vessel would lay another bigger trail of dust and other mostly dust carrying ships would dock until even nearer to the destination a bigger trail could be laid, enough so that the more delicate life carry ship can safely dock, probably consisting of cloned embryos and seeds.

    Once the embryos have grown in an artificial womb, they would be cared for and trained by human like robots until they were old enough to travel in 3d printed spacecraft to explore and colonise the destination star.

    The big craft would travel on to another destination.

    Not too much, it will be at least fifty years away.

    Probably have fusion by then or antimatter.

    Fungi that EATS radiation found thriving inside the Chernobyl nuclear reactor could be used like a 'sunblock' for humans to protect against deadly rays.
