If solar panels cost $1/watt, you can sell them (installation included) for $2/watt. Coal (installation included) costs $2.10/watt. To date, solar is still reaching to compete with coal, but the margins are closing. To (over)simplify how this works, you need to ignore issues like subsidies, qualitative costs, or kinks in … [continued]
(Picture courtesy of PedalPub) Bikes in Cleantechnica!? Of course! Isn’t the goal to consume less non-renewable energy? Just because we’re doing so with the good old bike doesn’t mean it is not worthy of the technology title–especially with the advances in bike technology highlighted below. And although I’ve long agreed … [continued]
One of the most common arguments against large-scale use of renewable energy is that it cannot produce a steady, reliable stream of energy, day and night. Ausra Inc. does not agree. They believe that solar thermal technology can supply over 90% of grid power, while reducing carbon emissions. … [continued]
What if computers didn’t get hot and batteries never lost their battery life? What if you could help power your car with the heat of its engine? Conducting electricity from one point to another, and then putting it to good use, is one of the linchpins of our modern lives. … [continued]
Got a forklift, 25G, and a desire to live wherever you want? Then the PowerCube from Reluminati is for you! Actually, with its ability to deliver 600-watts of continuous energy, the weight (1 ton) and the cost are the only two negative things I can say about it. Now, if … [continued]
Water shortages are on the rise, from Mexico to the Andes, northern China to southern India, and Spain to Pakistan. Drought, soaring populations and population densities, changing diets, and increasing living standards are all factors. Is this an issue that technology can fix? Judging by investors’ responses, the answer seems … [continued]
There’s been a lot of focus on renewable energy on Cleantechnia recently but energy is not the only “clean” tech out there. What about recycling wastes? What about recycling… human wastes? What’s the difference between traditional wastewater treatment and sewage purification (also known as ‘indirect potable water reuse”)? Is it … [continued]
After concluding last week’s post with water conservation tips, I was motivated to look deeper into more steps homeowners can take to conserve water, as well as the new technology surrounding this issue. I found all I needed (and MUCH more) at www.h2ouse.org. The website was created by the California … [continued]
Many businesses are putting the sun to work for them and saving a bundle on utility bills. While much of the country is experiencing increasing energy costs, some are looking to the sun as a solution. Although nearly all solar applications will eventually save money, a large upfront investment is … [continued]
Editor’s note: On Monday, Ecopreneurist’s lead writer Leah Edwards published this post on approaching venture capital firms with a cleantech business concept (with guidance from a member of one of the most influential VC firms in the world, Khosla Ventures). We figured a few of you out there are bouncing … [continued]
