Solar power

Read a mention of solar powered battery chargers in Profit Magazine the other day. That got me thinking about the vast potential that such devices hold. Then I saw my local Shopko carrying 8 solar lamps for $30 and I realized that solar energy is making silent but pervasive inroads in our day to day lives. We already have widespread use of solar water heaters back in Bangalore (India) where they are subsidized and cut a big chunk off electicity bills.

Upon further digging, I found this informative write-up of how solar lamps work. The authors write how solar energy was still out of reach for most consumers at the time of writing that article. We seem to have made tremendous progress in a short time – check out this travel solar battery charger that retails for $15 and is convenient enough to tuck into your backpack.

This may ultimaltely lead to the realization of one of my topics of interest – “wireless power”. We have freed the laptop of almost all cords and cables and now the only leash that tethers us to a fixed spot is the need for power. If we were to figure our more efficient ways of tapping solar power and make laptops more economical in their power needs we might find the solution some day soon. Another wild idea for transferring power wirelessly is magnetic fields although I haven’t the slightest idea how that can be made viable.

  17. It has a split on one end where you can push the cables
    and wires. Perhaps the most obvious here is that you are doing the environmentally responsible
    thing. Thankfully, we have the option of solar energy with us.

    them for specific information on the courses they offer.
    In some cases, you also have access to online forums to communicate with fellow students,
    where everyone can ask questions and share information about
    solar technology. A senior Greek finance ministry official said Athens would welcome Chinese buyers of its bonds.

  18. After I originally left a comment I appear to have clicked on the -Notify me when new comments are added- checkbox and now whenever a comment is added I recieve four emails with the same comment.
    Perhaps there is a means you are able to remove me from that service?
    Many thanks!
