The Cube generates more energy than it uses, thanks to the solar panels. It’s calculated that the average electrical power used by the Cube over a year in the southern part of the UKwill be around 260-300 Watts. This equates to 2280-2630 kWh of electrical energy demand over the year. Electricity prices will depend on country and tariff, but in the UKthis would cost about £300 per year. Other bills would include water and, perhaps, drainage (the latter depending on whether the composting toilet option is chosen) together with any local rates/tax. In the southern UK, this might be another £300. If registered with the UK Government’s Feed-in Tariff, the Cube’s solar panels would generate a taxfree, index-linked income of £1000-£1200 per year. If the ASHP is also incentivized under the UK Government’s Renewable Heat Incentive, then it might also generate an income of around £150-£200 per year. The Cube will therefore have negative running costs, that is, it will make a profit of £600-£800 per year.

The Cube isn’t put into production yet, but the team behind is developing this aspect. If you wish to be included on a mailing list of people who are interested (even vaguely) in acquiring a Cube at some point in the future, you can send an email to m.2.page@herts .ac.uk with the subject line “Cube purchase enquiry XX” where XX is your country of origin. You will then be updated on any developments. A 360 degree panorama of the interior is available here
