Heat Pumps Take on Cold Climates

Cars That Think

By controlling the compressor motor’s speed, and improving the timing of when vapor is injected into the compressor, engineers have made heat pumps efficient in colder temperatures. It’s generally well known that heat pumps can save money, but there’s a lot of confusion around whether they’re a good idea in all climates,” he says.

EPA Issues Proposed Endangerment Finding for Greenhouse Gases; Proposed Cause or Contribute Finding Identifies Motor Vehicles as Contributing Source

Green Car Congress

The proposed cause or contribute finding concludes that that the combined emissions of CO 2 , CH 4 , N 2 O, and HFCs from new motor vehicles and motor vehicle engines contribute to the atmospheric concentrations of these key greenhouse gases and hence to the threat of climate change.

EPA issues greenhouse gas proposals

Green Cars News

It has been deemed by the EPA that the emissions from new motor vehicles and their engines contribute to these concentrations and threaten climate change. The analysis also looked at the impact of climate change on human health and suggests that it may lead to higher levels of ground-level ozone, a harmful pollutant.

UTA researchers demonstrate one-step solar process to convert CO2 and H2O directly into renewable liquid hydrocarbon fuels

Green Car Congress

Researchers at the University of Texas at Arlington have demonstrated a new solar process for the one-step, gas-phase conversion of CO 2 and H 2 O to C 5+ liquid hydrocarbons and O 2 by operating the photocatalytic reaction at elevated temperatures and pressures.
