The Winds-day product from Amazon to the left is an educational wind power demonstrator that will let the little scientists in your life experiment with energy from thin air, if it’s moving a bit.
The Solar Ark company has systems of varying sizes to keep most of your appliances going, even after an otherwise devastating EMP (electro-magnetic pulse) attack. A high altitude nuclear detonation wouldn’t cause much damage to buildings and people, but could take out your nation’s electrical grid.
Don’t expect the Solar Ark system to handle your washer/dryer, but it supports some heating and air conditioning. (As Paul Wheaton pointed out in the 2013 video from yesterday’s post, just using an old style incandescent light bulb can heat you up while it gives off light.) A fan uses a tenth of the energy compared to a window air conditioner.
These days an EMP attack could be accomplished by any number of adversaries, such as Iran, North Korea, or even ISIS. Here’s a dramatic, well produced video series about the electrical grid vulnerability in the U.S. from NRA News, “The Fight For Light.” It’s narrated by Lt Col Oliver North, well known energy expert (just kidding), but credible military fellow: Part 1, Part 2, and Part 3. This series has the most detail about the threats to the grid and attack aftermath scenario that I’ve seen. Physical attacks have taken place, multiple times at the same location, even after security was beefed up, leading analysts to assume that a disciplined group was at work, especially since they’ve never been caught.
In case you think a pro-gun-rights source is making it up, here’s a report from MSNBC and USA TODAY working together, advocates of gun restrictions, noting a similar threat, “The Threat Against America’s Power Grid.” They suggest getting prepped with information from FEMA.
Getting back to wind power, and on a big scale, the embedded video below, from The Daily Conversation, is described at YouTube, “Offshore wind farms can stop hurricanes, according to a recent study. We could also use them to power all of America.”
