Co-Worker Paul is adding a hydrogen generator to his car, will it work, I'll let you know when I do.
(From left to right:) Hannah Dreissigacker ’09, Zoe Acher ’08 Th’08, Lucas Schulz ’08 Th’08, and Andrew Geffken ’08 Th’08 present their ENGS 290: Engineering Design Methodology and Project Completion design project—a pico-hydro generator.

running for 12 days during Hurricane Sandy power outage - Highly recommended - it is quieter (the others on the street were like boat engines) and a life saver!
**higher wattage would be better and recommended
The Singapore Airshow 2012 is the biggest, most advanced airshow in Asia at this date. One of the world's top 3 aviation summits, and serves as a global marketplace and networking powerhouse for the world’s aviation community and has always been greeted with tremendous support from industry players, solidly maintaining its position as Asia’s largest and top three aerospace and defence events in the world.
The Airshow was performed by the RSAF (Republic of Singapore Air Force), the RAAF Roulettes (Royal Australian Air Force), and Tony Blair (Australian Flight Instructor).
I visited the airshow exhibition with my military buddy, Shah, and his 2 friends. Shown in this set are photos of the F16 Fighting Falcon, the Apache helicopter, the F15, C-130 Aircraft, and the Rebel 300.

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).
