To get the most out of solar panels they need to be facing the right way. Systems that track the sun are often used in large solar power stations and some larger home installations, but most flat panels for portable applications just lie there. Colorado-based Aspect Solar has come up with the SunSocket Solar Generator, a lightweight, portable, self-contained solar power system consisting of a battery and solar panels that brings the advantages of automatically tracking the Sun to small applications.

The University of Delft has a program devoted to kite-based generation systems, with 20 years of research and development under their belt since Wubbo Ockels, the first Dutch astronaut established it. Now, members of the team are exploring practical niches where the compromises of kite-based power might pay off. One has just completed a trip through Kenya, Tanzania and Senegal discussing opportunities for rural African kite generation with governmental agencies, universities and companies in the renewables space.

One of the pressing needs in the event of a large-scale disaster or emergency is power. With Power2Serve, energy provider NRG is addressing this need head on in the form of 68 feet (21 m) of truck and trailer equipped with 40 kW of electrical generation and a Wi-Fi pavilion which people can use to communicate and keep abreast of events.

Neutron generators provide materials analysis and non-destructive testing tools to many industries, including oilfield operations, heavy mechanical construction, art conservancy, detective work, and medicine. Many of these applications have been limited by the rather large size of current industrial and medical neutron sources. Now Sandia National Laboratories, the lab that develops and supports the non-nuclear parts (including neutron generators) of nuclear weapons, has developed a new approach toward building tiny neutron generators.

Researchers at the Georgia Institute of Technology have taken advantage of the triboelectric effect, which sees an electric charge generated through friction between two different materials, to develop a generator that could supplement power produced by piezoelectric nanogenerators previously developed at Georgia Tech. The triboelectric generator could be used to produce electricity from activities such as walking and even has the potential to create touchscreens that generate their own power. Read More
Sun Flare Systems is a Canadian company that has developed a solar-powered backup generator. Designed to provide power in cases of outage and disaster, the patent-pending SOS in a Box kit is basically a small, portable power plant that includes a backup generator, flexible high-efficiency solar panels, and a charge controller. Sun Flare says its solar generation package is the first FAA and Airline Approved generator of its kind. Read More

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a new piezoelectric nanogenerator that promises to overcome the restrictions found in previous attempts to build a simple, low-cost, large scale self-powered energy system. Read More

K-TOR has added a new portable charging device to its lineup. The new Power Box puts your legs to work toward converting kinetic energy to electricity. Use it enough and you might just get your weekly workout. It is quite simply a pedal-powered generator equipped with a dual-pronged outlet so that you can plug in an AC adapter and charge your device directly from your leg power. The box works for devices rated 20W and below, including low-power netbooks, tablets, smartphones, video devices and portable game systems. Read More
The car is not going to disappear anytime soon and neither is the combustion engine, despite the inevitable rise in fuel prices. We have said it before, electrical motors are an energy-efficient method for driving vehicles but battery technology is simply not going to advance quickly enough for all-electric vehicles to be a practical reality for most uses anytime soon. The near and mid-term future is undoubtedly a combination of compact combustion engine generators charging dense battery packs that drive electric motors - the "range extender" option. We reported on one possible candidate, the disc motor, a couple of months ago. Now, after nearly twenty years of development another candidate is going through final testing and it is a work of elegant genius - Dr. Herbert Hüttlin's Kugelmotor. Read More
The mid-term future for fuel efficient vehicles with useful range is likely a hybrid solution of electric motors powered by batteries, topped up by a fuel-burning generator. Prof. Norbert Müller at Michigan State, backed by $2.5 million from the US Government, aims to make that last part of the equation a much more compact and efficient proposition with a revolutionary new form of combustion engine.
