Solar air conditioning

Here’s something that might make a difference. The ANU is developing a solar air-conditioning system. Air conditioning is one cause of peak loading on the electricity grid, when everyone puts on their air-cons at the same time on hot days. Reduce peak loading and you don’t need so many power stations.

You’d think some form of thermal solar air conditioning would be a no-brainer. After all, when do you need air conditioning? When the sun’s shining, of course.

At the same time, it’s interesting because a supposed inability to cope with peak loading is often cited as a drawback of renewable energy.

Talking of the ANU, if you’re wondering what’s happened to their sliver cell technology, which could dramatically reduce the cost of photovoltaic solar panels, here’s an update of sorts.

Multiply your PC, cut your emissions

A company called NComputing has brought out an interesting-looking gadget that allows multiple users to hook into one computer. Each computer needs their own screen, keyboard and mouse, but they all share the actual computer itself. The company says most computer users only use a fraction of the processing power and RAM of their computers, and so they can easily share the terminal.

The company says up to 11 users can hook up to one computer, with huge savings on hardware and software cost, and also on energy use.
