Google illuminates Berlin Festival of Lights with energy-harvesting walkway

To celebrate Berlin’s Festival of Light, Google has partnered with data harvesting firm Pavegen to build the largest ever energy-harvesting walkway. The footsteps of visitors to the world’s largest single energy harvesting array are being converted into off-grid electrical energy to trigger a synchronised lighting display and generate videos recording their experiences. 

The record-breaking 26-square metre installation can be found at KulturBrauerei, with its 100 electro-magnetic generators converting the kinetic energy so it can trigger 176 coloured light panels surrounding users (as well as providing data on the energy generated).

Blow petrol out of the garden with Ego's new lithium-ion powered leaf blower

Ego has unveiled a new leaf blower that drops a traditional petrol engine in favour of a far more energy efficient lithium-ion battery. The LB5750E EGO Power+ leaf blower will retail for £219 (including 2Ah battery and standard charger) or £149 without these accessories.

The LB5750E blower features Ego’s supreme high-efficiency brushless motor that delivers more power and a greater runtime than rival models, alongside a lightweight, compact design. It also boasts a large diameter blower tube for maximum airflow, generating a maximum air volume of 977m3/h, and an air speed of 212 km/h that shifts even the most stubborn leaves and debris.
