Cheaper Retina MacBook Coming; Ford Self-Driving Car Rescue Drone; Free Alexa Calling Moves to Tablets; 3D Printed MicroHomes in 24 Hours

There may be a new lower cost 13 inch Retina MacBook in June, around World Wide Developers Conference, according to 9to5mac.com. Word is, it will be priced lower than the present 12 inch MacBook. It will have the same pixel density as the present 13 inch MacBook Pro. If sources are correct, Apple will roll it out for just a little more than the $999 price of the present MacBook Air. This rumor doesn’t say it is an air, but since KGI Securities was already predicting a cheaper 13 inch MacBook Air, this could be the same device. The Retina display would be a first for this price level.

Long ago, Ford ran ads that crowed, ‘Ford has a better idea.’ Now, techcrunch.com reports on a patent that really is a great idea. Ford envisions a drone that could fly i and dock with a fully self-driving car in case of sensor and camera failure (which would render the vehicle helpless.) The docked drone would be equipped with its own sensors and cams, and could safely guide the vehicle home, or to a shop for service help. Getting such a drone out into the world will take time…but widely used self-driving cars are probably still 10 years away, too, so Ford has time to flesh out this idea!

Free calls and messages over an Echo speaker using Alexa is cool, and now that service has been expanded. Engadget.com says you can now use Alexa to place calls, video calls, and send messages from Android tablets, iPads, and Amazon’s Fire tablets. It’s a snap on the Fire HD 10, where you you just have to ask Alexa to get in touch. For other Fire tablets, you hit the home button first. On Android and iOS, you will need to open the Alexa app. You can also communicate with other devices in your house, basically making it a tablet to Echo or tablet to tablet intercom. This will reduce yelling by Moms when dinner is ready!

An Austin based startup is showing off 3D printable homes today at SXSW. According to theverge.com, they can print a house out of concrete (one report says cement, which is incorrect) in less than 24 hours…and have already printed a permitted micro house in Austin! The 1st one was about $10,000 for a single story, 650 square foot house with one bedroom, a bathroom, and a wrap around porch. (Note: no mention of a kitchen.) Icon believes they can get the cost down to $4000 each, and plan to start building in El Salvador. The idea is to ease the global housing crisis, but Icon says eventually they could produce micro houses in the US, too…up to 800 square feet with the present tech. (The average New York apartment is 866 sq. ft.)
