Getting bored with the power outages lasting for several hours in Bangkok lately I thought of way to extend power beyond the UPS time limit.

This is the test setup shown above. I used an old UPS where the battery was bust and it happens to be 12V, same as the car. This is pretty far from a “green solution” since the engine is running (maybe I’ll try solar panels next). When the load increase so does the rpm of the car engine when the generator kicks in. I’m not sure how much I dare to hook up on this thing but should be enough to keep the essentials like the PC’s running, at least until the gas tank is empty.
