This is such a "worn" idea. In the early nineteen eighties, I was responsible for ways to convert stored energy to generate power in Measurements While Drilling (MWD)Systems. One way was to harness the stored energy in downhole shock absorbers coupled to various generators, magnetic voicecoil motors, piezoelectric crystals, hydraulics, etc. Working models were constructed, but I did not patent them. After leaving the company (NL Industries, Houston. TX) "they" did patent the ideas and took the credit!!!

Now, if only someone would talk to Cybex or some other gym equipment maker and come up with a way to convert that wasted fat enery into energy that can be stored. Some kind of friction-based kinetic transducer, or a pressure transducer instead of dumb weights... Seems a shame to see that huffing and puffing go to waste.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
