    In 1927 Fuller resolved to think independently which included a commitment to "the search for the principles governing the universe and help advance the evolution of humanity in accordance with them... finding ways of doing more with less to the end that all people everywhere can have more and more."[

The Electron is round. Incredibly round | ZME Science - 59 views

  • The experiments, which spanned more than a decade, suggest that the electron differs from being round by less than 0.000000000000000000000000001 cm. Just so you can get an estimate, if the electron were as big as the solar system, it would still be spherical to within the width of a human hair.
  • a team from the Imperial College London concluded that the electron is actually incredibly round, thus making the most accurate estimate of its shape.

Thinking about solar? It's easier to start small | Green Tech - CNET News - 12 views

  • Thinking about solar?
  • Green Ray Solar this week is expected to announce UL certification for a solar panel that puts out alternating current, rather than direct current as most solar photovoltaic panels do today. AC panels can be simpler to install and wire together than traditional panels, which makes a piecemeal approach easier,
  • Traditionally, solar panels are tied into a device called an inverter, which converts the direct current from panels into household alternating current. Strung together, several panels produce enough voltage to run an inverter which, sized for a rooftop array, is roughly as big as a computer monitor.

  • A microinverter brings that DC-to-AC function onto each individual panel. Proponents say the technology simplifies installation and improves panel performance.
  • For example, shading on one panel will not affect the output of other panels connected to it, as happens with panels connected to a centralized inverter.
