Tiny thermoacoustic engines pave the way for screaming gadgets

Looks like all that heat generated by your laptop may finally be useful for something other than frying eggs -- a group of grad students led by professor Orest Symko at the University of Utah has unveiled an array of "thermoacoustic" engines that turn heat into sound, which can be directed at a piezoelectric mechanism to produce electricity. The US Army-funded research seems promising but is obviously still in its infancy -- one of the designs the researchers demonstrated is half the size of a penny but pumps out 120dB of noise (about the same as a siren), while another bumped out over 135dB, (which is roughly equivalent to a jackhammer). The team expects that future, smaller designs will work at ultrasonic frequencies outside the range of human hearing. Although we're not expecting hybrid-siren-powered laptops to hit anytime soon, you Utes out there may want to invest in some earplugs -- Professor Symko says they'll be testing these designs at the University's water-heating facility in the next year.

Google and Salesforce Tightly Integrate Adwords Products

There’s been a lot of speculation about Salesforce and Google lately. Tomorrow the two companies will announce a marketing and distribution alliance that will tightly bind Google Adwords to existing Salesforce tools that track sales from online advertising.

Salesforce and Google will be starting an extended partnership encompassing marketing and distribution of their products across 43 countries. It will begin with the integration of Google Adwords and Salesforce’s lead generation tools into a new application called “Group Edition”, available here. Group edition replaces Salseforces earlier version Team edition.

dashboardsmall.pngGroup Edition will enable Adwords users to track Adsense referrals to their site and build up a customer profile based on a the data a user enters into a site and their navigation path. Businesses will handle their Adwords campaigns through Google, as usual, but Salesforce takes over from there. When potential customers click through to the businesses site, Google tells Salesforce what search terms brought the user to the page and where they navigate throughout the site.

It is our understanding that the technology behind the salesforce side of the deal comes from Kieden, an company that they acquired late last year.

Site owners can also drop “web lead forms” onto the site, which can collect any other customer information (names, email, phone numbers) and bundle it into customer profile. All of this data is enumerated on a dashboard view, which you data on lead generation, sales, and growth. As with any other Salesforce application, users will also be able to mash up the data with other AppExchange Apps. The application will cost $600 for 5 user accounts and come with $50 of Adwords credits.
