Summer is here, and for technocrats, that means more than just mojitos and barbecues. Here are some useful and fanciful gadgets to help you make the most of your time enjoying the sun, surf and lazy weekends of the season.

The Auto Mower from Husqvarna is like a Roomba for the lawn. Able to manage inclines of up to 35 degrees, the Auto Mower uses a rechargeable nickel metal hydride battery to quietly trim and mulch unwanted grass. It can be set to run at night and will automatically return to its base to recharge as needed.

A wire buried just underground sets the parameters for the $2,000 Auto Mower, though it can go around the occasional tree on its own. Safety sensors are in place to stop the blades, which only run while the mower is in motion, from harming children and small critters who might reach underneath the device. While winter storage is recommended, the Auto Mower can withstand rains and winds typical of other seasons.

Looking for a green status symbol? The electric could be for you. Yes, it costs three times more than a Vespa and only goes 60 miles between charges, but it might be just the thing for quietly tooling around the Hamptons or Santa Monica.

For something that runs off nickel metal hydride batteries, the Maxi Scooter is zippy, sort of. The $11,000 scooter does 0 to 50 miles per hour in about 6.8 seconds.

The Solaire line of infrared grills from grills faster with ceramic burners that emit infrared heat (between microwaves and visible light on the light spectrum) powered by the usual propane. A Solaire grill's burner takes only three minutes to heat up and cooks food 50 percent faster than a typical gas grill, according to the company.

Because the food cooks from a direct source of high heat (temperatures range from 340 to 950 degrees) evenly spaced, food is supposedly seared more quickly and retains more moisture than it would with gas or charcoal grills. The average hamburger takes seven minutes total to grill, according to Solaire's own directions.
