Watching a bunch of kids parade as Cleopatra, witches, ghouls, storm troopers and even “John’s Portaloo”, it reminded me that Halloween stuff is fun. With all that is going on in our world today, it’s great to pause and lighten up. And a great chance to talk about some of the stranger happenings when it comes to renewables, sustainability and greener living.
Energy Vampires lurk in our homes
Southern California Edison (SCE), is one of the largest electric utilities in the US serving more than 13 million people. Earlier this week, SCE released a warning for its customers about the scary “energy vampires” that lurk throughout their homes and businesses. Instead of sucking blood, these vamps are our household electronics that draw electricity even when they are off. In fact, SCE estimates that you could save up to five percent of your bill if you simply unplugged or turned off items like DVD players, computers, stereos, TVs and computers.
Military robot eats biomass – and bodies?
It seems that FoxNews originally ran a story that a long-range, long-endurance military robot designed by Robotic Technology Inc foraged and powered itself with organic “biofuels.” Biofuels like fruits, veggies, cooking oils … oh, and bodies. Animal and human remains left on the battle field. But according to Dr. Bob Finkelstein, then-president of RTI, that simply wasn’t and isn’t true. Instead, his company’s Energetically Autonomous Tactical Robot or EATR is only sustained by plant-based biofuels, solar and traditional fossil fuels (oil, gas, kerosene, propane and coal). It turns out that EATR is programmed to recognize specific fuel sources and avoid others. As Dr. Finkelstein puts it, “If it’s not on the menu, it’s not going to eat it.”
Harnessing ghost energy
There was a lot of discussion around the Smart Grid this week following a $3.4 Billion infrastructure investment announcement that would fund 100 projects in 49 US States. IBM, one of the key vendors in the quest for Smart Grid supremacy, is promoting its offerings for home and business. During a 6 month pilot of 100 homes serviced by Fayetteville Public Works Commission in North Carolina, the use of Smart Grid technologies cut residential energy expenses by up to 40 percent. IBM’s goal with the pilot project was to highlight the energy used by “ghost” devices: air conditioners, water heaters, and other devices that are using electricity even when no one is around.
Who knew we had so many ghosts and vampires living daily in our homes. Energy saving is good. But did you hear about bad energy ghosts, which have nothing to do with the grid but do seem to be something to keep in mind when building or ungreen?
Pumpkins power up cell stations
Ericsson, self-proclaimed world’s leading telecommunications supplier, began experimenting a few years back with biofuels-powered cellular networks. Its “green” macro base station was targeted at rural areas in developing countries that didn’t have access to a main electrical grid. The project, launched in Nigeria, used locally grown pumpkin seeds as well as groundnuts, jatropha and palm oil. There are few other details from Ericsson. Pumpkin seeds do have very high oil content and are purportedly very tasty and good for you. However, like other food stocks, they simply require more energy and aren’t truly viable as biofuels feedstocks to drive engines. They do however make great compost!
If interested, the EPA also has a listing of power pulls from all your tools and appliances. So if you’re considering using power tools to carve your pumpkin, you might want to see what you’ll get for the energy expended. Literally…
Trees are one of the hottest items right now when it comes to
