I saw a program and some guy had a small solar panel and crap black box that trickled the charge to the phone
Got me thinking sitting on my laptop in the sun on the decking coding watching my battery go down and thought why and when will a manufacture whack these in, it must be a good idea no?
With the shrinking form factor and in terms of cpu less power and less heat (still amazes me that before things got faster but bigger and hotter and now its more performance and faster but smaller and cooler as a result of less juice needed) so their must be room say apple did it for example.
You got your mackbook and either a slip of solar panels in a cool looking knight rider way on the lid or inside depending which would get the most light and be used to charge up the notebook. Now it will not place your in the wall charger but it would certainly expand you cable free usage would it not? and then as I am sure they would be advertised as saving the planet
Not a bad idea, you could probably build one yourself your
adapter gives like 20 volt and 4-5 amps right get panels that
give that much and you are in business. The dump find I have want 20 volt 6 amps but I run it on 19 volt 2.5 amps but it is not enough to charge but the it runs (those litium batteries will not charge if not enough current).
Simplest way is to get a 12 volt panel and connect it up to a pair of car batteries, then convert to 240 volt and supply your lappy through its normal PSU.
With this sort of system you can also power a few 20watt low energy light bulbs too. No more darkness if the mains fail.
TBH Ive been thinking of doing this myself, connecting the batteries between the mains and lighting with an uninterruptable power supply type setup.
The efficient ones are still super-duper expensive.
4kW cost us about £30,000
that was heavily subsidised in the end though...
I bought a 12 volt 2 amp one 1979 made by Arco for $300, a whopping 25 watts :)
not that efficient but it charged batteries enough to drive a lappy though.
I think it is the future, I was just thinking about my mac and other notebooks that also have the giro thing in them to protect the hardrive but also give you a cool light saber sounds, lol...
Anyway you could use that as well to create a charge, very small but when your solar panels get viable as well then it all adds up to extra life.
I do see it happening one day
Can you imagine what it would be like if the govt. decided to convert all existing buildings roofing to solar energy, and the tech was there for energy storage? All these green houses on TV always seem to brag about how they end up putting energy back into the grid. I wonder if combined, all urban areas using solar energy, would be able to power the nation...?
Itd cost the govt. a load to subsidise it all, but at the same time how much would it cost in developing another nuclear station and replacing the aging ones, not to forget the cost of nuclear waste...
didnt some dels have coils in the keys so as you typed it generated power for you ?
I remember reading about it.... but havent seen anything about it cince then...

TBH it isnt cost effective yet for here in the UK, much better putting them in sunnier climates and shipping Hydrogen gas, if this works properly.
