Do something

I've been doing a lot of work on green energy and particularly solar these last few days.

And I can't for the life of me understand why solar isn't more popular in Australia.

I was thinking perhaps it was because it was a relatively new technology but then I came across this pic.

It's the legendary Charles Eames demonstrating his Do Nothing Machine.

An experimental solar powered toy that he created in 1958.

That's over 50 years ago!

Which brings me back to my question - Why isn't solar more popular?
