- Dept of Energy posts videos pushing Solar Energy -- wasn't Trump Admin going to kill Solar? Most of the Trump Administration appointees are people who seem tasked with killing the departments they're overseeing. The US Department of Energy is headed by Rick Perry, who in the 2012 race had promised to kill that department. We've been worried the DoE programs on solar energy and other clean energy technologies would vaporize, and we'll all fry in a few years because climate change will be running rampant. These are very real concerns, but it's useful to check whether the reality measures up to that fear. These video releases are perhaps a sign that the Dept of Energy will continue promoting solar power.
- Energy 101: Concentrating Solar Power From towers to dishes to linear mirrors to troughs, concentrating solar power (CSP) technologies reflect and collect solar heat to generate electricity. A single CSP plant can generate enough power for about 90,000 homes. This video explains what CSP is, how it works, and how systems like parabolic troughs produce renewable power.
- Energy Department Announces Projects to Advance Cost-Effective Concentrating Solar Power Systems and 2014 CONCENTRATING SOLAR POWER REPORT Concentrating solar power (CSP) is a technology that harnesses the sun’s energy potential and has the capacity to provide renewable energy to hundreds of thousands of customers in the United States. This report discusses how 2014 marks a significant milestone in the history of American solar energy—with five U.S. Department of Energy-funded CSP plants expected to be fully operational by the end of the year.
- Solar-Electric VW Bus conversion Generally speaking solar powered electric vehicles aren't feasible because the weight and aerodynamics of the solar array offset any gain the solar panels might give. It's a dream many have, solar powered vehicles, but in reality-land it doesn't work too well. Unless your vehicle already has the aerodynamics of a brick, such as the old-school VW Bus. This nice video shows an excellently thought-out VW Bus EV conversion that has an excellently thought-out solar array attached to the roof. The installation covered the struts holding the array in place, for example, to minimize aerodynamics problems. Going by what's said in the video, the system offers 40-50 miles of EV range (using a lead-acid battery pack, the next phase is a Lithium-ION pack giving a couple hundred miles rage) but a fairly lengthy recharge time because the system produces 12 amps peak. That last bit confirms the problem with solar powered EV's -- it's difficult to carry enough panels to recharge the vehicle in a reasonable amount of time. Also notice that the VW Bus is parked at an odd angle in the parking lot, because it has to be oriented optimally to the sun.
