Lowering the number of drives that are spinning reduces the data center heat load and thus reduce the HVAC settings in the data center.

Here, we expect to have a very low heat load.

Mr Green also said that prospective buildings should be well insulated to reduce the "heat load", the amount of heat the system needed to deliver in order to warm the property.

To come up with a quote, a good contractor will do a heat-load calculation to determine what size unit and how much piping to install.

In a vacuum, a conventional circuit breaker -- which measures heat across a load -- doesn't work, because there, there's less or no atmosphere there to draw the heat off, so a conventional circuit breaker would trip.

But with cogeneration they can bring that 45% up to 90% assuming heat and air conditioning loads at the load site.

Another approach effectively steers magnetic nanoparticles toward disease sites where they dump their therapeutic load or else destroy cancerous tissue with heat.
