The RFID and the saguaro

As somebody who used to have a front yard with a saguaro cactus, I understand why people pay up to $1,000 for them. Last year the law caught rustlers trying to steal 17 of these Sonoran Desert natives. So the National Park Service in Tucson, Arizona is planning to imbed chips in the cactuses to track them in case the plants go AWOL.

“We would likely not just go out and implant, but would gather data, GPS the locations, and record heights and widths and measures,” [Saguaro National Park chief ranger Bob] Love said. “We probably wouldn’t implant a plant that was not healthy or a desirable plant for someone to steal.”

Nevada chipped some of its barrel cactuses in 1999 to deter theft and help take inventory.

The little house that could

The house's heating water tank

Built for just £210,000, Michael and Dorothy Rea’s house on Britain’s northernmost inhabited island is amongst the most efficient in the world. Boosted by the strong winds surrounding the island of Unst, the house has its heating and power, plus an electric car and substantial greenhouse, entirely powered by renewable sources.

The house reminds me a little of the building in Susan Palwick’s ‘Shelter’ with its smart uses of technology. The house takes heat from the air around it and stores it in a water ‘battery’ to heat the home. The greenhouse uses hydroponics and LED lighting to simulate growing seasons, allowing hothouse plants like lemons and peppers to thrive. Is this a sign of how we will live in the future?
