# Key Points from IRC Log (April 20, 2010)

• A parametric timing pulley design was shared on Thingiverse (http://www.thingiverse.com/thing:1362), representing ongoing interest in open-source hardware components for DIY engineering projects.

• A link to aerogel.org was shared, indicating interest in advanced materials with potential applications in transhumanist technologies.

• Discussion of the Mars Science Laboratory mission included its nuclear power source (RTG - Radioisotope Thermoelectric Generator), scheduled for launch in Fall 2011 on an Atlas V rocket.

• A significant scientific discovery was discussed regarding extremophiles - specifically a loriciferan found at ocean depths that appears to live without oxygen, representing the "first metazoa living in permanently anoxic conditions" (paper: http://www.biomedcentral.com/1741-7007/8/30).

• A deltabot made with Arduino and RC servos was shared (YouTube video), demonstrating the growing accessibility of robotics through open hardware platforms.

• Open hardware and licensing discussions were referenced, including content from Adafruit forums and presentations by Phillip Torrone and Limor Fried on "Citizen Engineer - Consumer Electronics Hacking and Open Source Hardware."

• A link was shared to an article about a "shock bullet" technology that delivers an electric charge, showing interest in emerging non-lethal technologies.
