Being slightly alarmed at the world financial situation (see this :
One aspect is evening lighting, and perhaps laptop and router power. I've been thinking that perhaps a deep-cycle (wikipedia terminology) lead-acid 15v battery charged from solar cells along with a suitable converter to get my 240v (like the e:can/e-can 150w device).
But I have no knowledge of electricals except that solar power recharging may not be practical in a relatively cloudy country like the UK, especially in winter. But then again perhaps I could still get myself enough power for several hours of a CFL bulb. Better than nothing.
What would you advise?
