Transphorm introduces Gallium Nitride diode; >99% efficient DC-DC boost converter

Green Car Congress

is showcasing a GaN-based, dc-to-dc boost converter running at more than 99% efficiency. Energy loss that occurs during power conversion is equivalent to the daily output of 318 coal plants, and costs the US economy $40 billion per year. At APEC, startup Transphorm Inc. —Primit Parikh, President of Transphorm.

LanzaTech exploring lipids production as part of its CO2 to acetic acid plans; pathways to renewable fuels

Green Car Congress

Accordingly, LanzaTech has begun look at the industrial conversion of acetic acid/acetate to lipids, and has demonstrated this. LanzaTech envisions using partner technology to convert the acetic acid to lipids—i.e., that conversion wouldn’t actually happen in a LanzaTech bioreactor. Carbon Dioxide as a Feedstock.

Let My People Convert! - The A123 Challenge

Plugs and Cars

Les Goldman wants you to convert (your hybrid.) So he proposed at the California Air Resources Board ZEV workshop on Tuesday. Tuesday's workshop was not so different. ARB could spend a year in conversation with stakeholders to figure out regs and credits for new OEM plug-in hybrid cars. Let the people convert!

Fraunhofer IAF develops first monolithically integrated GaN half bridge for voltage converters for e-mobility

Green Car Congress

Half-bridge circuits are the centerpiece of many voltage converters. For example, the switching frequency can be improved by a factor of around 10 in comparison with conventional voltage converters. A folded chip layout enables the DC link capacitance to be tightly connected between the supply voltage and ground.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

The projected number of charging ports will need to grow to an estimated 6,000 to 12,000 public ports (some 300 being DC fast chargers) and 18,000 to 26,000 residential ports, with most of those being L2-type charging ports. For instance, Marshall stated, it is not unusual for a 37.5

EPA Proposes New Regulations for Renewable Fuel Standard to Implement Requirements of EISA; GHG Reduction and Indirect Land Use Change Effects Included

Green Car Congress

The agency will hold a public hearing on 9 June 2009 at the Dupont Hotel in Washington DC. It will also conduct a workshop on 10-11 June 2009 at the Dupont Hotel to present details of the lifecycle GHG analysis. Satellite data are used to predict the types of land that would be converted into cropland (e.g. EISA and RFS2.
