Thermal energy keeps dancers going in Scotland
If you're a news addict like I am, you'll have
noticed an extra dose of doom and gloom lately. There’s the terrible war
in Ukraine, divisive politics in the U.S. and inflation and rising
prices pretty much everywhere.
However, on the bright side, a Scottish nightclub has found it can
reduce its carbon footprint by 70 tons per year if it collects body heat
from dancers.
There's a nightclub in Glasgow, Scotland that has a dancefloor that
absorbs body heat from the dancers and converts it to thermal energy,
between 250 and 600 watts depending on how intense the music is.
The thermal energy is sent inside fluid to a hole that lies 200 metres
underground. There, it's charged like a thermal battery before being
pushed back up to provide heating and air conditioning inside the
nightclub.
Medium intensity music like the Rolling Stones could generate 250 watts,
whereas a modern dance DJ who pumps out the beats and gets the dancers
jumping up and down, could generate thermal energy in the region of 500
to 600 watts.
At a total cost of £600,000, this clean energy system wasn't cheap to
install. Nevertheless, the club owners calculate that they can recoup
the investment in five years by disconnecting the gas boilers and saving
on costs that have sky-rocketed due to recent price increases.
The advantage of using water as a heating system is that while it
requires a lot of energy to heat up, it holds onto that energy much
longer than air. With the fluid that carries the heat stored underground
it’s well insulated, and therefore also more efficient than any gas
heating system.
Other venues, including the famous SchwuZ nightclub in Berlin, have also
expressed interest in this technology. High-profile nightclubs don't
want to be left behind when it comes to the latest and coolest green
energy installations.
It's not only about saving money and protecting the environment, it's
also about being fashionable!
