Lots to talk about this week, including a gravity-defying quantum levitation skateboard, Lytro's revolutionary new camera, the future of Android skin, and a robot helper for man's best friend. Plus, Donald shows off the nerdiest way to feed your baby, Rafe protects you from phishing scams, and Eric has the latest from Blizzcon.
FRANKFURT--Here's a riddle for luxury automakers: How will big, high-powered cars fit into a world that's greener, more congested, and more tightly regulated than today?
Mercedes-Benz rolled out one possible answer here last month with the F125 concept car.
The F125 checks off many of the boxes on automakers' future-think wish list: hydrogen fuel-cell power train, high-priced materials, computer-assisted driving, advanced telematics. So it's tempting to see it as a science project.
But if you listen to Thomas Weber, r&d chief for Mercedes' parent company Daimler, you realize that the F125 addresses a serious concern--the … Read more
This week, Donald and Eric tackle some big tech ideas while fighting off a dark cloud of Nietzschean existentialism.
Microsoft demos shoulder-mounted touch-screen projectors, while Disney takes a decidedly low-tech route. We also look at a ball that can take 360-degree panoramic photos in one shot; advancements in harvesting energy from humans; the strength of your passwords; and a new spin on superhero teen shows.Subscribe in iTunes SD Video | Subscribe in RSS SD Video
To measure a country's greenhouse emissions from fossil fuels, it makes sense to consider the whole carbon supply chain, from oil well or coal mine to a consumer's shelf, scientists reported today.
Currently, putting a price on climate-warming carbon dioxide generated by oil, coal, natural gas, and other fossil fuels typically takes place where the fuel is burned.
However, this may not be the most effective way to calculate carbon emissions' cost, the researchers wrote in the journal Proceedings of the National Academy of Sciences.
Carbon dioxide generated by human activities such as coal-fired power plants and factories … Read more
Short of employing a full hybrid system, automakers are finding many ways to improve fuel economy in current, gas-engine cars. Engineers are looking at every part of the drive cycle to determine where savings can be made.
Some of the technologies being employed are old, such as turbochargers and continuously variable transmissions, but they are being refined to take advantage of new materials and computing power.
There have also been some newer innovations that cut fuel use, such as the use of idle stop and dual-clutch transmissions.
A number of factors are helping push these developments. Consumers are trying to cope with increasing gas prices, and governments are pushing for reduced carbon dioxide emissions, which relate directly to fuel economy.
Now there's an app to tell you how to make commercial buildings more energy efficient.
Startup FirstFuel announced today it has raised $2.4 million from venture capital companies Nth Power and Battery Ventures to commercialize a software system to remotely evaluate and measure commercial building efficiency.
What's unusual about the application is that it doesn't require a person to be dispatched to perform an energy audit or install meters to gather data. Instead, the company collects utility data on hourly energy consumption and combines it with weather information to create a profile of a specific building. … Read more
Recently, I took a road trip from San Francisco to Los Angeles to drive the 2012 Toyota Camry Hybrid. When I told friends that I'd driven over 5 hours one-way just spend even more time driving when I got there, the question I got most often was, "Wouldn't it have been cheaper to just fly?"
Had I known about the Cost2Drive Web service and iOS app at the time, I'd have been better equipped to answer that query.
After entering a starting address, ending address, and a make, model, and year of a vehicle, Cost2Drive … Read more
Electric vehicles may seem like the inevitable evolution of the conventional gas-powered automobile, but not every carmaker agrees. Hyundai will sit out the pure-electric car round, and instead concentrate its efforts on designing the next-generation hydrogen fuel cell vehicle.
As part of a decision by the Hyundai-Kia Automotive Group, Hyundai--which owns 51 percent of Kia--will stop all efforts to develop and produce electric vehicles, according to Korean newspaper The Chosun Iblo. The auto manufacturer previously planned to produce the all-electric BlueOn, but it has shelved those plans and instead will focus on developing the Tucson ix Fuel Cell Electric Vehicle. … Read more
A Hyundai Tucson left San Francisco this morning, heading to Los Angeles in the first leg of a cross-country trip. But this trip is no family vacation; the Tucson will be picking up handprints from children as it makes stops at pediatric cancer facilities. And the car will not burn any gasoline in its travels, as its fuel cell stack converts hydrogen into electricity for its drive motor.
Hyundai's Hope on Wheels tour is designed to raise awareness of pediatric cancer, and present 71 hospitals with $100,000 grants to fund researchers. Childhood cancer patients and survivors will add … Read more
Michigan's Mass Transportation Authority isn't waiting around for the hydrogen highway to come to its neck of the woods. The transit organization is building an alternative fuel testing ground for its planned fleet of propane and hydrogen-electric buses. When it's completed, the entire facility will be powered by an on-site solar farm, including the hydrogen generators.
Mass Transportation Authority canceled its orders for electric buses that achieved only a 40-mile range, and instead will be purchasing hydrogen-electric buses that have a 300-mile range to meet its clean-energy needs, according to an article in the Flint Journal.
Working … Read more
