In 1940, the newly built Tacoma Narrows Bridge began to vibrate violently and soon collapsed in windy conditions. Ever since, engineers have focused on ways of stopping their structures vibrating in this way. Now, a group of Spanish engineers is working to harness the energy potential of vibrating structures. Instead of using the wind to […] Read more »
A “refrigeration battery”, which stores cooling for later use, can cut peak electricity demand by as much 40%. Read more »
Engineers at the University of Alabama are testing a passive cooling system for computer processors that they believe could save U.S. consumers more than $6.3 billion a year in energy costs associated with running their computer cooling fans. Read more »
Scientists at UCLA have developed hybrid supercapacitors that can store as much charge as a lead acid battery, yet can be recharged in seconds compared with hours for conventional batteries. Read more »
Scientists have developed a heating process that converts the “peanuts” used for packaging into carbon anodes for lithium batteries.
As well as eliminating waste, the technique produces batteries that recharge much faster because the carbon anodes are only a tenth as thick as their commercially available counterparts. Read more »
