While this spacey-looking disk will not allow your car to time-travel, it might replace its internal combustion engine
Here’s a new approach to decreasing the environmental impact of cars: a new auto motor could make them 20 percent lighter and reduce emissions by 90 percent.
Michigan researchers have built a prototype of a disk-shaped shock wave generator that could replace the current internal combustion engine in cars. The generator is about the size of a saucepan and does not need a transmission, cooling system, or emissions regulation fluid, which would reduce the weight of a vehicle by 1,000 pounds.

An aerial view of damage to Wakuya, Japan, after March 11 earthquake and tsunami
Last Friday, Japan was hit with a devastating earthquake of 9.0 magnitude. In combination with the following tsunami, the earthquake caused immense damage to northeastern regions of Japan and severely compromised six nuclear power-plant reactors. Recent reports estimate the death toll at over 5,000, with another 9,000 people missing and 2,500 injured. Over 4 million households were left without electricity, and 1.5 million without running water.
Since the tragedy stuck, scientists and engineers have been working around the clock to find and help survivors, as well as to avert potential nuclear meltdowns.

The structure may resemble a postmodern radio tower or perhaps the lair of a James Bond supervillain, but it’s actually designed to be a hydrogen power plant.
Hydra, named after a tubular freshwater creature, is listed as an honorable mention in this year’s eVolo Magazine Skyscraper Competition (see more winning designs here). Its creators hail from Serbia, and include Milos Vlastic, Vuk Djordjevic, Ana Lazovic, and Milica Stankovic.
The most remarkable aspect of this structure is its ability to harvest energy from lightning bolts, which is then stored in several huge batteries at the base.

Every hour, the sun beams down more energy than the whole planet consumes in a year. Although solar cell technology has advanced considerably in recent years, many challenges related to reliably capturing and storing the sun’s energy still remain.
Sossina Haile, a professor of Materials Science and Chemical Engineering at CalTech, is developing a new approach to solar power. Using cerium oxide (or ceria), a metal most commonly found in self-cleaning ovens, Haile and her research team have created a prototype reactor that has the power to transform sunbeams into clean fuel.
