How Fossil Fuel Interests Attack Renewable Energy

It is so predictable that the first comment or two of any renewable-positive article comes from one of these renewable bashing group that the article exposes. I hope the gig pays well.

A New Way To Harness Waste Heat

Right on Dr. Nelleore, that sounds like a universal application if the average temperatures corrolate. I hope the author responds.

New Battery Design Could Help Solar and Wind Energy Power the Grid

Anonymous- You speak of thermal storage as if it is easy and cost-effective, right now. Can you please inform us specifically where cheap, thermal storage can be found? Water and rocks of course meet the definition of cheap until you actually have to build a system to use the material. Then it becomes totally impractical in most applications because of the shear volume material needed. So, are you talking about something new, perhaps an inexpensive phase change material?

Resolutions To Reverse the Unsustainable Solar Industry

I believe Anonymous's first comment is correct. Half of all energy used in the US does not require electricity but thermal energy instead. Sunlight converts to thermal energy at efficiencies of up to 80% while PV efficiences are still in the teens. Collecting sunlight for space heating is not very complex, thus it is not very sexy or technically difficult. A commercial solar space heating array can cost as little as $8.00 a therm installed. A comparable installation of PV on a sq. ft. basis costs $181.00 (convert kwh to btus) according to the DOE.
The State of Oregon gets it. I believe they are the first State to offer solar tax credits specifically for Solar thermal (water or air) in the country. Solar thermal is able to use both the sun's infrared waves and visible light. Infra-red waves contribute over 50% of the energy from the sun. Thermal loves infra-red but PV hates them, they produce heat.

The common sense of going with the low hanging fruit of thermal solar is beyond obvious. Visible light starved Oregon gets it. Too bad Washington and the other northern tier State legislatures don't. Solar Thermal needs a better PR team.

Ken,

I agree and I too have been trying to find the holy grail for decades. I first started trying to sell thermal solar in 1978. That is why this time around I concentrated on a technology that does not need incentives. Non-conductive transpired solar collectors and NREL patented technology, in an agricultural setting costs less than a $1.50 sf in materials and a $1.00 sf to install including a VFD. So, even here in the worst sunlight in the country, Seattle solar thermal, solar space heating is works.

George and Patrick,

I think everyone in this discussion would agree that bringing back the sawtooth design would be advantageous. But we have 4.2 million commercial buildings in the US right now that are under 50,000 sf and that have flat roofs. Those flat roofs are the "last great frontier" of open urban space in America.

Do we plaster those roofs with PV's at 15% efficiency or do we create the first real wave of "renewable energy blue collar jobs" and install Fabric solar space heating collectors as pre-heaters to every HVAC unit above the Mason-Dixon line? I vote Fabric solar space heating especially when it is the "least expensive and most efficient solar energy product yet developed"- US Department of Energy

Right on Larry,

Cost-effectiveness is the only thing that counts. We live in a capitalistic society thus the cheaper mouse-trap is always a competitor. The ROI is the only thing a business cares about. Larry is obviously going in that direction. Please tell the rest of us when your system competes with retail natural gas at .88 a therm.

Larryofgalaxy,

This response is related to your request to know what renewable energy application currently available that can compete with natural gas @.88 therm.

A non-conductive transpired solar collector, is the answer. Sunreps http://sunreps.com has been working with the 6th largest poultry processor in the country, Foster Farms, for the past two years to build and installed solar space heating collectors for poultry barns at an installed cost of less than $2.50 sf. in the Pacific Northwest.

In Western WA and OR sunlight is in short supply. So, for a product to be competitive against natural gas and propane it has to pay for itself within three years.

Primer:
Chicken barns worldwide require about 4 weeks of heat between 80-90 degrees 24/7 out of every 8 weeks. The single highest expense of growing broiler chickens is heating fuel.

Canadian chicken producers have been using Solarwall, the original transpired solar collector for over 20 years very successfully. The US DOE is on record as stating that a transpired solar collector is THE most-cost-effective solar product yet developed. Solarwall is made of metal. Sunreps' fabric transpired solar collectors are 6 times less expensive than Solarwall.

The National Renewable Energy Laboratory a division of the DOE is the patent holder of this technology. Sunreps is the exclusive worldwide patent licensee of this technology.

The technolgy is also applicable to every HVAC unit on every commercial building above the 35th parallel (Mason-Dixon line)

There are few skills or tools needed to build and install the Sunreps Sunfish collectors. This presents the ability to allow low skill, low wage blue collar workers across the country an opportunity to work in solar on a massive level.

This is probably more info than you wanted but I'm trying to be thorough enough that you realize this is factual information, and now a pipe-dream of what could be, it is happening Now.

Larry,

You asked a question. I gave you valid answer. I'm not hear to pick flyshit out of the pepper.

The US spends equal amounts of money on space heating as it does electricity. Fabric transpired solar collector work on one problem, space heating and they do it better than anything else yet developed.
