Great piece. I'm associated with another company that does this kind of work (full disclosure: Recycled Energy Development) and there really is a massive amount of potential out there, as Olson says. Indeed, the DOE and EPA data suggests we could slash U.S. greenhouse gas emissions by 20% solely through combined heat & power and waste energy recovery. Meanwhile, costs would plummet due to increased efficiency. We should be doing far more to create a policy structure that's conducive to this kind work -- particularly at a moment of economic and environmental crisis.

As I read the BIO of William C. Olson, Richard Langson, Stephen R. Olson and Robert C. Hoover II, could not resist, but to post herein below my comments.
Human brain is expandable by brainstorming. You don't have to be Socrates, Einstein, Edison and alike, nor a Nobel Price holder, or an Engineer in Physics and Thermodymics, to come up with a clear intent and purpose. Obviously, those stewards were assisted by Professor Ian K. Smith, Professor Nikola Stosic and Professor Ahmed Kovacevic, who are also an integral part of the ElectraTherm.
BECAUSE [Strong emphasis added], I respect those who brainstormed, in-the-box, rather than those proclaimed as the best and entitled to control the market and the energy' sector, first let me applaud the folks from ElectraTherm.
It is irrelevant of what others may think about my comments, since I will not respond to any one, on any platform, as well as will reject even one red penny offered from those in the Financial Community that has sponsored those others, regardless that I may end just like Ericsson did in 1889.
Furthermore, I may say the same about the Recovered (free) Energy and Source, as then in about 1992, Newton Becker, Luz Co. Chairman of the Board, stated in the end: "The failure of the world's largest solar electric company was not due to technological or business judgment failures but rather to failures of government regulatory bodies to recognize the economic and environmental benefits of solar thermal generating plants."
(Hope, identical scenario does not repeat its self now, again by LUZ-II, being their 07-AFC-5, not limited to the wrangling associated therewith 07-AFC-8, causing frustration and bitterly exits by many Renewable Energy IPPs, all the way to other countries.

Continued
"Recycled Energy" is in fact a "Recovered (free) Energy and Source", further termed as the Alternative Energy and when brainstormed, by integrating and synergizing the embodiment into one mass, can supersede the renewable energy sector, not only in utility scale electric power generation of more than 46 GWe, but in the other two of the most needed sectors, Water Management and Agricultural Food Production, thus Power-Water-Food is at-issue, debuts.
For the same reasons mentioned herein above (wrangling), I am implementing the Super Hybrid Facility' Complexes, for just about the development cost of a coal-fired plant, unfortunately in another country, and when, soon I am done, you will witness electric power generation by a recovered (free) energy of the "Plumes Turbine-Generators", integrated with the "SpiroWindGenerators for AquaBioHydroponic Greenhouses, nights operation (within the 24/7/365 operation for growing high value crops, to feed the Californias) and CSP Twin Parabolic Collectors and Receivers, utilizing its HTF for Seawater Desalination by Distillation Plant, in synergy with cold/frozen air make-up units, utilizing the cold/frozen air to condensate steam to water at the desalination plant, for irrigation/process and other industrial purposes, also utilizing recovered (free) energy for its operation, obviously utilizing as an assistant, less that 15%, fossil fuel-fired reciprocating engines-generators.
Then, we can talk cold turkey. (While others are endlessly talking, we do the real walking and on another (foreign) turf and Playas, however will not welcome those others, except ElectraTherm.)

UTC also makes a low temperature ORC generator for waste heat/geothermal generation, (see Raser), but even these guys have to actively seek colocation of tertiary use of the lower temperature waste heat from their condensers such as anaerobic digesters and district heat storage. Apparently most heat generators are too dumb to take advantage of their waste heat and even solar wastes >60% of the energy absorbed by their panels as heat, with the notable exception of a few companies that are building PV/T systems, (see DawnSolar, Zenith Solar, etc). The vast wanton waste of heat demands a new law to either prohibit the waste, incentivise waste heat recovery or both.

There is no "law" needed, except to reform tax laws. Too often tax laws prevent planning to do things the "intelligent" way. Co-generation has been around a long time, but Federal and local laws prevented it, or it's planning. The other problem is the "thinking" taught in MBA schools, which is extremely short term (days, not years). Profit _right now_, not next week, or next year. As long as tax laws and "MBA think" are focused on today, not tomorrow or the day after, we will continue to have the same problems.
Reform "MBA think" not pass new laws.

Simply increase the price of fuel. Greatly. That'll focus all sorts of minds.

I noted a slow down in car speeds, people took less unnecessary journeys and there was a great interest renewables during the recent oil price hike.
Keep it up I say.

could a staff writer do a survey of this field. Every time I pass a coal fired power station I see great plumes of steam coming out - obviously this is lower grade heat and thus of less utility but how much really can be utilised?

The main piece above is inspiring but not informative.

The production of power from low grade heat is not very efficient, with typical ratios of generated power to received heat (thermal efficiencies) of less than 10%. One company, alone, ORMAT industries has built and operates worldwide, nearly 1,000 MW of power plant, based on the same operating principles as those of ElectraTherm. In 2006 UTC installed a 250 kW electrical power generating system in Alaska, using geothermally heated water to make electricity. Again, based on the same operating principles as those of the ORMAT and ElectraTherm systems.

What then, is novel about the ElectraTherm waste heat power recovery system? Mainly, it is that such a relatively low power output system can be produced at an economic cost. The cost of installation of such a standalone system, which only needs to be piped up to the hot water source and a cooling water stream to become operational, is relatively small and if such a system is run continuously at base load, then at 10 cents/kW hr, a not untypical value today, the 50 kW ElectraTherm unit cost, together with the price of its installation, can be recovered not in decades but in less than three years.

Most large scale power plant use turbines to expand the gases or vapours, contained in them, that produce the mechanical power, required to drive an electrical generator. However, turbines are best suited to large power outputs and on a small scale, they become excessively expensive and can account for more than 40% of the total system cost. ElectraTherm has avoided this by using screw expanders instead. The advantage of the ElectraTherm system is that their screw expanders were designed as a result of a $5 million research program carried out in a UK university. This resulted in a novel lubrication system, by means of which they were able to achieve a fourfold reduction in cost, while at the same time the expander efficiency was increased by nearly 50%.

Energy is indeed wasted in the US. We have 5% of the world's population, we consume 25% of the world's energy reserves, and yet we have a trade deficit, a budget deficit, a growing debt, and a little bit of a recession too. Inexcusable, isn't it?

Whereas recovering heat from stacks and exhausts is a great idea, it seems we need much less energy to achieve the same level of success, so why not simply reduce the energy generation? (Evidently energy consumption per capita is neither the culprit for this morass nor the solution to get out of it.)
