Blogroll Review: Sinks, Oranges, Woz

by Frank Ling

Power Bathroom

For many years, the Japanese have recycled sink water for their toilets. Now an American company is taking it further.

WaterSaver Technologies from Kentucky has developed the AQUS system, which Philip Proefrock at EcoGeek says:

“…collects the water from a bathroom sink and filters and disinfects it before it gets re-used as flush water for an adjacent toilet. (There is nothing that would prevent this from being used in a large-scale LEED project either.)”

The toilet can save up to 7300 gallons of water each year.

According to the Word Water Council, that’s enough water to produce 2 kg of beef. 🙂


Apparently you can get more out of oranges than just orange juice. Some guys have figured out how to convert the citrus peel into ethanol.

Jim Fraser at the EnergyBlog says:

“FPL Energy said that ethanol from citrus peel could result in a new Florida industry producing over 60 million gallons of fuel per year, which could replace about one percent of Florida’s annual gasoline.”

If only they had a way to make Pine-sol smell orangy….oh wait, I guess they already have. 🙂

Green Woz

Al Gore, Leonardo DiCaprio, and Cameron Diaz are all out there pushing for a greener future. But it doesn’t hurt to have more celebrities out there to garner support.

Steve Jobs (from his own blog!) quotes his old buddy Steve Wozniak as saying he wants to reduce his emissions:

“I have a long dream to build my own house in a very energy-efficient approach. That’s going to be very soon. It uses the right kind of wood that serves as a heater and as an air conditioner.”

    Steve Jobs from his own blog! I think not. That's Fake Steve you are plugging into, not the real thing. Nevertheless, the link to Woz's dream house quote seems real. But just what wood can he be talking about? Apple?

    1) I love that the World Water Council can turn water into beef.2) That's one (1) percent from all the waste citrus peel in Florida (a statement equivalent to "all the tea in China" I'd imagine). One percent.3) I think the wood Woz is thinking of is called "stone". A stone house is fairly expensive to build, but – as I live in one built in the mid 19th century – they're comfortable from minus 40 degree (celsius) cold to 40 degree heat. Woz is a wiz with the silicon, but apparently not with wood.
