The optimal control of the whole installation, pumps included, requires continuous assessment of the mass flow rate of the solid liquid mixture.
Households in England and Wales can apply for up to £5,600 to pay for solid wall installation, double glazing, boilers, cavity wall and floor insulation.
Householders can claim up to £4,000 for solid wall installation (down from £6,000 last time), up to £1,000 for two measures from an approved list that includes a condensing mains gas boiler, secondary glazing, floor insulation and energy-efficient replacement doors.
British-born Anthony McCall's piece You and I Horizontal is a bewildering solid light installation that uses a video projector to create what seems like a thick wall.
"Diluting the ambition of the scheme, and dramatically reducing the amount of solid wall installations, would increase winter deaths and fuel poverty in cold homes, and put 10,000 people out of work in the energy efficiency industry," he said.
The government's Committee on Climate Change predicts energy efficiency in homes could be improved by 35% by 2020 with an ambitious programme of improved insulation (covering 10 million lofts, 7m cavity walls and 2m solid walls), the installation of 12 million energy-efficient condensing boilers, and major improvements in electrical appliance efficiency.
In California, software giant Adobe Systems has announced the completion of the largest commercial Bloom Energy solid oxide fuel cell installation so far, rated at 1.2 MW.
Furthermore, because installations like solid wall are generally bigger jobs than loft lagging they employ more people so the potential for jobs growth – up to 60,000 in the insulation sector alone by 2015 is built in.
These are not mere installations but solid buildings (you can walk into and through them), placed within the museum in a way that enhances their architectural host and its kaleidoscopic collections.
Here, a flexibility premium that includes solid fuel-powered biomass installations might have been appropriate in order to encourage the relevant changes in feed-in behaviour and make flexibilisation investments worthwhile [55].
