: Mulskinner [Hi-]Tech Review V [ I/2010 ]
During past weeks I dropped by at Ikea. I usually avoid the place; Reason that my feet start aching from just walking past/through shops corridors and several departments. I rarely buy anything for I can't figure any place in the world for all that furnitures, cups and pots, plastics and napkins, textiles, toys, decorations, etc., etc. Cheap but boring. Consumeristic purgatory and marathon track in the same (for anyone who doesn't particularly like the offerings of their kitchen and enlightening informative signs)...But I also noticed them taken steps all in the spirit of this eco-conciousness our times require and demand - sorting of bio- and energy-wastes also was clearly informed and advertised.
But anyway, despite my slight antipations I've bought stuff there too. Without particular seeking for, picked this Solar-lamp. Probably as much an eco-fashionable choice, to not much underestimating my own shopping behaviour. Probably few energy-saver bulbs would take care of similar savings. Also, even optimistically thinking I'm not too sure if eco-saves from my buy ever closely compensate, say driving the benzin-engine few hundred kilometer or the every-day uses of this laptop, fx... But I though the product a forerunner of its kind (not much seen these around) and so gave it a try.
...And noticed it actually quite functional of design and use. The bulb can be turned for any directions and weights much nothing. The charger is easily detachable (see pic beside) , so it can be brought for good place to charge separately. I at first considered lamp as a reading light, but then noticed the promised 3+ hours and bulb light perhaps little too dim for regular use in that. So, I now have it merely as a movable light for various tasks, for working desk, handicrafts, etc. Perhaps less plugging for the electricity-grid. (Although, not having too much daylight now either, Ive actually charged separate batteries of the electricity-grid to lenghten use time. – Not probably most recommendable way to use, since opening lid reveals the wires for lamp beside the battery case).
Also can be brought along in places without electricity otherways available – rarely so, but it's sometimes pleasant to ease up without all that bright 'cold' light.
The cover looks like it keeps the most water out/some drops of rain wouldn't cause harm, but I'm not sure if its watertight enough to leave out in the open. Therefore, user probably still needs keeping little eye on the weather. Promised around 10+ hours charging time (in less of sunshine, cloudy) isn't perhaps reasons enough to recommend it for any continuous use. Apparently there's some way to go. Half the charge time needed and it would appear pretty efficient, flexible device, actually.
Noticing the above, said (though, I wouldn't try this on amount of sunshine here at MSW), theoretically a few lamps with some additional charger could be enough for (modest) lighting needs of small household. Wouldn't of course handle any other regular (energy) uses, but would appear quite inspiring experiment to try. Would perhaps also pay back relatively soon, if one's prepared in some watching and replacing chargers. Though, a single larger panel probably makes far more practical solution for anyone building his own housings.
Since it's been darker days and heavier weather, I've really not had much chance to use it in practice – So guess'll add few lines from how it behaves on the spring when we receive more hours of sunshine. (W-G.)
However, naturally it gets rather boring changing them often, so in the coming summery times I guess I'll be using only the solar cell regularly - like the orginal purpose of the device. Otherways it can be further underlined that it's actually very useful having this kind of movable lighting source. Only, of course, like in the case of these renewable energies more commonly, user (the consumer) needs little change one's own adapted patterns of use acc. the usability available from origin of this energy (sun). Yet, it's further noticed that with little improvements, fx with charging time been able to cut for half with more efficient cell (panel actually, more probably, precisely) would make this very recommendable device - even better, probably doesn't appear too difficult to manufacture by larger numbers, without much trouble...
