A DIY E-bike Conversion on the Cheap

Cars That Think

Purpose-built electric bikes and e-bike conversions using hub-motors are now commonplace. this month's Gizmo column , which each cost thousands of dollars. That got me thinking, how hard would it be, and how much would it cost, to do a simple conversion now? One thing that hasn't really changed, though, is the expense.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

The chemical process employed by the scientists also could reduce costs and energy requirements for producing liquid hydrocarbons and other chemicals used by industry. The conversion normally requires significant amounts of energy in the form of high heat—a temperature of at least 700 ?C,

Researchers develop efficient single-atom Ni catalyst for conversion of CO2 to CO

Green Car Congress

If there were a sustainable, cost-efficient route to transform CO 2 to CO, it would benefit society greatly. A competing reaction, called the hydrogen evolution reaction (HER) or “water splitting,” takes precedence over the CO 2 conversion reaction. —Eli Stavitski, a scientist at Brookhaven and co-author.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely. —Mao et al.
