MIT's Solar Powered Recharging SOFT Rockers

Architecture students at MIT, led by Professor Sheila Kennedy, recently unveiled their latest design for the Massachusetts’ based school’s 150th anniversary Festival of Art+Science+Technology (FAST). These solar powered SOFT rockers allow you to plug in and recharge your USB device while relaxing outdoors. With a soft wood construction, the rocker makes use of the balance from human body weight to create an interactive 1.5 axis 35 watt solar tracking system.

Also incorporated into the design is a 12-ampere-hour battery that harvests and stores solar power during the day for use during nighttime hours. A strip of light can be turned on after the sun goes down that runs along the interior of the lounger. The charging stations were on display at the university’s Killian Court for students to gather while having the convenience of plugging in.

Time will tell if these solar loungers will make it to production, either as is or in a more polished form, but they could add a touch of efficiency and innovation to the average backyard.

The Best 12V Solar Battery Chargers

Justin Thomas — Thu, 01 Jan 2009 18:05:15 +0000

Note: This post on 12V Solar Battery Chargers has been updated for 2010.

Solar cells really shine at charging your batteries at remote location or on a boat. They are also useful for maintaining a charge on a 12V battery, such as a car battery. The best (and most expensive) solar battery chargers are flexible, thin-film solar cells. These cells can be folded and packed away easily.

Sunforce Solar Battery Chargers

You can find get basic solar charger for under $25, such as the Sunforce 1.8 Watt Solar Battery Maintainer. These solar charger are good for trickle charging or topping off the charge of a 12 V battery. Sunforce chargers get good reviews from owners at Amazon.

You can plug the Sunforce 1.8-watt solar charger into your vehicle’s 12-volt lighter socket and position the panel to pick up the most daylight possible. Or, if you prefer, use the alligator clips to connect it directly to the battery, so you can keep your lighter socket open for cell phone chargers or other accessories.

A higher wattage charger will charge your battery more quickly. When in doubt, opt for a higher power charger because owners are often disappointed with the charging times of lower wattage chargers. Sunforce offers a 5 watt charger, a 15 watt charger and a 60 watt charger. However, once you got over 15 watts, rigid solar cells start to get bulky, so you might want to opt for a flexible solar charger (see below)

Another good range of solar charger is the Coleman solar chargers, which are similar to the Sunforce chargers.

Brunton Solaris 26 Fleixble Solar Battery Charger

The Brunton makes a good range of flexible, portable solar cells. Brunton solar charger use CIGS (Copper Indium Gallium diSelenide) instead of the usual silicon.

The entry-level Brunton charger is the Solaris 6, which produces 6 watts of power. However, most remote users opt for the Brunton Solaris 26. This flexible solar charger that generates 26 watts but measures only 21.5” by 37.5″ and folds down to 11″ by 8.5” by 1”. The Solaris 26 is available from Amazon for around $425.

Solaris chargers can charge a laptop, video camera or 12V deep cycle battery. They are often used to charge marine batteries. It takes between 1 and 2 hours to charge a small device using the solar cells. It takes between 4 and 8 hours to fully charge a laptop computer. Brunton’s chargers operate well in low-light conditions such as overcast days.

Brunton Solaris 52 Solar Battery Charger

Brunton also offers the Solaris 52, a 52 watts solar charger. It’s available from Amazon for $891 .

Portable Power Station

A useful addition to a solar charger is a portable power station. A power station will store energy generated by the solar cells, so it can be used when needed (like at night). Brunton offers the Solo series of lightweight power stations. These units can be recharged by plugging them into a USB port, household outlet, vehicle DC outlet (cigarette lighter socket) or by using Brunton’s solar panels.

Brunton’s lightest power station is the Solo3.4, which weighs just 12 ounces. It has a 3.4 Amp/H lithium-ion battery inside, and it can be used to charge a variety of small electronics. It comes with adaptors for iPod, mini USB Motorola, Nokia, Sony Ericson cell phones, and Playstation PSP.
