We propose a concept that makes CO2 capture a distributed waste management activity we all perform, rather than leaving it up to large industrial scale projects. In this concept, we submit that city buildings are able support collection modules, and the collected gas can be captured in sorbents or converted into useful materials such as solid carbon.
A dual axis solar tracker is a device that serves as the scaffold to support photovoltaic cells and maintain their orientation to the sun accurately throughout every day of the year. The largest portion of the cost for a solar tracker is primarily the cost of structural materials, and in particular steel. Our proposal centers on a design that reduces the amount of steel required for a high performance sun tracking platform, reducing cost more than 30% without sacrificing the current functionality of a dual axis solar tracker. Our design also supports the use of alternative rigid structural materials such as bamboo in regions of the world where bamboo use improves the economics over steel.
An innovative approach to reuse silica-rich mine tailings as material inputs to value-producing processes and materials. This concept essentially transforms mining waste of certain ores that are high in silica content into three sustainable sub-products: glass for solar reflectors for concentrated solar power plants, industrial environmental sorbents and clean solar electricity.
A novel method for rock comminution using a new form of explosive pulverization or shattering based on transcritical CO2 cycling. Fundamentally, this concept intends to replace (or at the very least significantly complement the functionality of) the current large mechanical devices used to shatter rock, their high energy consumption, maintenance costs and heavy environmental impact.
Metal powder bed 3D printing processes need to be able to better characterize part density before a part is created, by knowing detailed information of the powder density as it is spread in the printing process. We designed and built a proof-of-concept measurement apparatus to determine spread metal powder density in a typical powder bed spreading process.
A smart city assistant personalizable for every citizen and visitor, using any language; accessible through web, mobile devices & public kiosks. At the core of this concept is a digital twin platform of the city with useful information such as municipal services, city-specific feeds like traffic, events, real-time alerts, tourist information and other relevant opt-in data sources.
