Automaker to release its MX-30 SUV equipped with the iconic motor later this year.
TOKYO — Mazda Motor is planning to revive its iconic rotary engine in a plug-in hybrid car by the end of this year as it attempts to simultaneously please fans and cope with tougher environmental rules in its main markets, such as Europe.
Two heads are better than one: new electric truck from Tevva deploys hydrogen fuel cell and battery technology for maximum efficiency.
Mahle claims the motor can run continuously at 90% of its max output, with durability assured by a new integrated oil-cooling technique.
The Future of Earth: 1,000 Years From Now.
In the last 250 years, humans have drastically and irreversibly transformed the Earth. Greenhouse gases emitted by human industries have changed the planet’s climate, presenting the single greatest threat humanity has ever faced. If humans can cause such incredible damage to the Earth in 250 years, what will our planet look like in 1,000 years time?

A little while ago, we covered the idea of using photovoltaic materials to drive enzymatic reactions in order to produce specific chemicals. The concept is being considered mostly because doing the same reaction in a cell is often horribly inefficient, because everything else in the cell is trying to regulate the enzymes, trying to use the products, trying to convert the byproducts into something toxic, or up to something even more annoying. But in many cases, these reactions rely on chemicals that are only made by cells, leaving some researchers to suspect it still might be easier to use living things in the end.
Paul Woskov of MIT shows a sample of what a gyrotron can do to vaporize solid rock. The technology may soon help to harvest geothermal energy.
Geothermal renewable energy is the forgotten cousin of wind and solar. An old Soviet-era technology, the gyrotron, may soon change that.
The first tandem perovskite-silicon solar cells to exceed 30% efficiency have been independently certified.
