Google PowerMeter Graphs Electric Usage

Next time you run the dryer for an hour just to take care of a dozen socks, you may just get a kick in the pants from seeing the spike, in real-time, on your own electricity usage. On Tuesday, Google introduced a Web application known as PowerMeter that could help homeowners monitor their own electricity usage in the future.

By communicating with smart power meters that relay usage information back to power companies (rather than just spinning a dial to record it,) PowerMeter will display a graph of electricity usage over time, with different trends labeled to show the appliances that are causing them. Google hopes to introduce it as an iGoogle application, allowing users to keep an eye on usage easily, and therefore change their habits to cut down on waste.

In Google’s promotional video for PowerMeter, one engineer claims to have cut his own usage by 64 percent and saved an estimated $3,000 on his electricity bill using an early version of PowerMeter.

Though Google has handled the software implementation, consumers won’t be able to take advantage of it without smart power meters, which remain rare, and the right standards for publishing the information that they produce.

For the moment, PowerMeter remains a closed release in private testing among Google employees until the hardware side of the equation falls into place for the public. According to Google, that could be soon, since the proposed economic stimulus package (PDF) on the table in Washington includes provisions for the installation of 40 million such meters over the next three years.

SimpliSafe launches AI-powered detection system alongside the new Outdoor Security Camera Series 2

The SimpliSafe Outdoor Security Camera Series 2 mounted outside.

After spending some time in early access, SimpliSafe’s Active Guard Outdoor Protection feature is now available to the public. Using AI technology in conjunction with its team of security experts, Active Guard Outdoor Protection is designed to detect and stop crime before it happens. It’s available on the new Outdoor Security Camera Series 2, though you’ll need to enroll in a monthly membership to get full use of the service.

SimpliSafe isn’t new to the world of AI-powered crime prevention, as you’ll already find a similar feature on the Smart Alarm Wireless Indoor Camera. That functionality is great -- but if an indoor camera is picking up intruders, it means they’ve already made it inside your home. The Outdoor Security Camera Series 2 and Active Guard Outdoor Protection are looking to fix that, as the system can react to threats and alert SimpliSafe agents within 30 seconds of catching a motion event.

Mowing a lawn can be very therapeutic unless you have an older lawnmower, which makes life difficult and constantly causes you frustration. Luckily, you can snag a new lawnmower for a pretty good price, and even the more budget-oriented options have a lot of quality-of-life features that you wouldn't find on lawnmowers ten or even five years ago. To that end, we've gone about and collected some of our favorite lawnmower deals across the board, including some great robot lawn mowers that are worth checking out.
Litheli Cordless Lawn Mower U20 Handy+ -- $120, was $140

If you want a solid lawn mower, this offering from Litheli has a 13-inch cutting width, which is pretty good for the deal that you're getting. Even better, you get a 30L grass bag so you're not having to clean up after yourself, and you can mow for longer without having to stop. You also get 5 height adjustments so you can hone in the length of your grass to the perfect height, plus you get a 4.0Ah portable battery included.
