Underneath the Chicago Fire Department's Engine 60 in the Hyde Park neighborhood, there's an old Cold War remnant: a large bunker that could have housed people for up to two weeks in the event that nuclear fallout sent everyone underground.
Here, Kyle Bolyard checks out an old Onan brand generator in the underground vault. He asked Curious City about fallout shelters in Chicago.
Random Generators created by AnjaliDeshmukh. According to festival site"As a participatory installation, it produces for and with “players” a work of visual art that is aesthetically meaningful and creative. It is also intended to spur for players a confrontation with fate or existence and serve as a conduit through which meaningful dialogue can occur between complete strangers.

First test of the turbine on 14 white LEDs, showed that above 100 mA (total), LEDs doesn't increased brightness linear with increasing current as expected.
At one point, current still increase but resistance/impedance of the generator is pretty high to supply that current without loses at generator itself (overheating coils).
It is not so obvious from brightness of the LEDs, but it is obvious by looking at frequency vs. current intensity.
Some data still missing - not much wind past few days to check all possible wind speeds, and all possible measurements.
I am expecting similar situation with accumulator battery charging. Those LEDs has threshold about 2.5V (not sure exactly), and below that voltage, no current flow at all.
Exactly that will happen with battery charging, but it will depend of how empty or full battery is.
So, proper electronic have to be made in order to maintain proper current and protect against overload/overcharge for both: generator and accumulator.
The emergency generator being delivered to the side door of the new Crossbar telephone exchange (exchanges run on 50v battery power) being built at Bexhill on sea. About 1971.
Taken with a tiny minolta 16 sub miniature camera and scanned from the old negative.
This picture is one of a possible series, taken in the 70’s and 80’s.
None of them are commercially sensitive, as all the exchanges no longer exist, and only show parts that were visited by the general public on open days.
Here the plasma generator is controlled and supported by a maintenance drone (yes, the Aeldari have them but do not use in combat).

USS Albacore (AGSS-569)
Portsmouth, NH
USS Albacore (AGSS-569) was a unique research submarine that pioneered the American version of the teardrop hull form (sometimes referred to as an "Albacore hull") of modern submarines. The revolutionary design was derived from extensive hydrodynamic and wind tunnel testing, with an emphasis on underwater speed and maneuverability.
We believe this was the power generating room (the blue room) for the Buckner building in Whittier, Alaska. It had a large muffler (painted red).hanging from the cieling. We think the people that took the generator out are responsible for the hole. The rest of the the mess is due to time and destructive people that have torn the place apart over the last 40 years.
Not all of the generators are actually put to use regularly, as contrary to popular belief the dam's first priority is not power but irrigation to the Imperial Valley in southeast CA. It was initially put into place as a means of "taming" the Colorado River's cycles of drought and floods.
09/2016 Neptune Aviation Services, Alamogordo, NM. Worked on these in Ubon Thailand 1973. How about the drive. Would run down people if they slipped. Had one roll over after C-141 made a turn.

Exhaust Snorkel In Place
On the playa, I fix the location of the snorkel by hose-clamping the elbow to a 2-ft x 1/2-in piece of rebar driven into the ground about 1 ft. Then I move the generator to snug it up to the elbow.
The exhaust should exit as far from the ground as practical and preferably well above head-height for people walking by. On the playa, I slide a 10-ft x 1/2-in PVC pipe over the rebar stake and extend the ducting as far up the PVC pipe as it will go. I hose-clamp the ducting to the PVC pipe at the far end and at a couple of places in the middle. The ducting will vibrate and rattle against the PVC pipe in the slightest wind if it isn't secured in several places along the pipe. Very annoying in the middle of the night, I assure you.
