Solar Panels to Heat Your Home
Saving thousands of dollars every year can be done by the generation of free, renewable energy. The depressed economic environment means we all need ways to reduce expenses the way…
Chemistry controls magnetism
Magnets are well-known from the physics lessons at school, but they are hardly covered in chemistry lectures; and it is still a chemical process by means of which researchers have succeeded in controlling magnetic properties in bulk ferromagnets. While physical processes may influence the orientation of the magnetic fields, the chemical process in this case controls magnetism in carefully chosen strongly ferromagnetic material systems. The working principle used in this case is similar to the concept of lithium-ion batteries.
Shifting winds: An early warning for reduced energy
Chinook winds can precede large shifts in wind power output from wind farms — a challenge for companies seeking to provide a constant stream of green energy to consumers. By establishing a connection between local meteorological events and power grid output, the researchers hope that they may ultimately help grid operators more accurately predict fluctuations in flow and manage the grid accordingly.

Perpetual youth for batteries?
A key issue with lithium ion batteries is aging. It significantly reduces their potential storage capacity. To date, very little is known about the causes of the aging effects. Scientists have now come a step closer to identifying the causes in their latest experiments.
Aerodynamic effects can save tens of seconds in cycling time trials
Will the Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing.

Storage advance may boost solar thermal energy potential
Engineers have identified a new approach for the storage of concentrated solar thermal energy, to reduce its cost and make it more practical for wider use.
New flow battery offers lower-cost energy storage
Renewable energy can be stored for less with a new organic aqueous flow battery, which uses inexpensive and readily available materials. The new battery is expected to cost about 60 percent less than today’s standard flow batteries.
