Monthly meetup of two cleanweb companies. Enjoy some food and beverages as cleanweb companies shares what they're up to.

At the beginning of each meetup, we ask if anyone is hiring so people can follow up about jobs in the cleanweb community after the event.

GridCure (– analytics for the smart power grid. The company’s pitch is that power companies have invested billions in smart meters at their customers’ homes and businesses, but haven’t built the software needed to make the resulting deluge of data actionable. With GridCure, those power companies will be able to spot where power should be re-routed (wasting less energy overall) as well as identify irregular activity that could indicate “stolen” electricity.

Persistent Efficiency (

produces energy sensors ("Power Patch") that easily attach to the surface of individual circuit breakers and automatically measure the current carried by the conductor inside the breaker.

The Power Patch can effectively mitigate the interference caused by signals carried by neighboring circuits, i.e. breakers and wires that they are not affixed to. In other words, the Power Patch meter outputs an electrical signal that is proportional to the current it is measuring and will not be affected by nearby signals. This procedure is typically performed by adding a reference load to the circuits and observing the corresponding changes in the sensors’ output.

What is cleanweb?

Cleanweb is a category of cleantech that intersects with and leverages the capability of big data, the internet, social media and mobile technologies to address energy, natural resources and the environment. Cleanweb goes beyond the typical images associated with clean technology and power generation – PV panels or wind turbines – to include the broad range and huge potential of all types of digital media and information technology.
