Edison vs. Tesla: The Battle of the Energy Inventors. Our panel of experts answers your questions about two of the greatest energy inventors, Thomas Edison and Nikola Tesla. Editor's Note: Thanks to everyone who participated in our lively discussion about Thomas Edison and Nikola Tesla! Our panel of experts answered your questions on everything from alternating vs. direct current and how we are wirelessly transmitting energy today to Tesla's heroes and whether Edison was a great geek or a great CEO. If you missed the Hangout (or even want to relive the live discussion), you can watch a recording of it above. More than engineers, scientists, businessmen and rivals, Thomas Edison and Nikola Tesla were two of the greatest energy inventors of all time. Some of their most significant contributions -- from the battery and power plants to alternating current and the electric motor -- came to light more than a century ago, and yet, they are still influencing how we use energy in our everyday lives.

Old-Fashioned Steam Engines Could Solve Solar Energy Storage Problem

Australian engineers might have solved one of the biggest obstacles to scaling up solar energy — the lack of affordable storage technology that allows solar to be used at peak demand after the sun goes down. Their California-based startup Terrajoule is applying an older technology, namely steam engines, to build a storage system that could lower the cost to under $100 per kWh, which is less than 20 percent of what it costs for current battery storage systems. This new system will also last longer (it has a 25 year lifecycle), thereby eliminating use of the toxic and rare materials contained in batteries.
