# Key Points from IRC Log

• Xentrac discussed Dyneema yarn's remarkable properties, calculating its specific energy capacity as a spring at 60 kJ/kg, which approaches battery-range energy density, though high creep makes it impractical for battery-like applications.

• Fenn proposed alternative approaches to cryonics storage, suggesting that using different refrigerants with higher boiling points and solar-powered refrigeration could significantly reduce long-term storage costs beyond liquid nitrogen.

• Discussion of energy storage technologies included flywheels (with notes on reducing friction by aligning with Earth's axis) and compulsators (compensated pulsed alternators) as power supply forms.

• An open-source electroporator project was shared, aiming to create a $250/kit alternative to commercial units that cost $2,000-7,000, with programmable pulse capabilities for cell transformation protocols.

• Kanzure and TMA debated the economics of human emulation, with TMA arguing that "not-quite-human emulations" would be more economically valuable than human ones, while Kanzure suggested emulation could eventually be cheaper than healthcare.

• The Cybathlon, described as the "first cyborg Olympics," was mentioned as an upcoming event in Zurich (October 2016) where competitors with disabilities would use advanced prosthetics and assistive technologies.

• 3D printing discussions included using OpenSCAD for designs and techniques for duplicating objects by manipulating STL files with coordinate offsets.
